Premio internazionale per la tutela dei cetacei a Sabrina Giannini, giornalista di Report

Tredici organizzazioni attive nel campo della ricerca e tutela dei cetacei hanno conferito alla giornalista Sabrina Giannini il premio “Cetacean Conservation Star” per il suo impegno nella sensibilizzazione del pubblico riguardo al sovrasfruttamento delle risorse ittiche e alla pesca illegale con reti derivanti, un vero flagello per delfini, balene e altre specie minacciate del Mediterraneo.

Le tredici organizzazioni, che rappresentano circa 400.000 soci, hanno deciso di premiare Sabrina Giannini per il documentario “Mare Nostrum”, realizzato per la trasmissione di RaiTre “Report” condotta da Milena Gabanelli.

Nicolas Entrup, portavoce di WDCS, la Whale and Dolphin Conservation Society, ha affermato: “Sabrina Giannini e i suoi collaboratori hanno documentato il proseguimento della pesca illegale con reti derivanti e hanno chiarito i meccanismi che consentono questo scempio, che spesso avviene sotto gli occhi delle Autorità italiane”. “In seguito a questa denuncia molte reti sono state sequestrate e le attività di pesca illegale sono state interrotte, si spera per sempre, salvando così la vita a molti delfini, capodogli, mante, tartarughe marine e altri animali protetti che cadono vittima di queste reti”.

“Documentare l’impatto distruttivo delle attività umane che minacciano la vita nel mare è di enorme importanza”, ha sostenuto Xavier Pastor di Oceana Europe. “Sabrina e i suoi collaboratori di Report lo hanno fatto molto bene e con grande coraggio, riuscendo a ottenere risultati importanti e sensibilizzando il pubblico e le istituzioni sui grandi problemi legati alla gestione della pesca in Mediterraneo”.

Il premio è stato consegnato da Giuseppe Notarbartolo di Sciara, Presidente onorario dell’Istituto Tethys, nel corso di una semplice cerimonia tenutasi presso l’Acquario Civico di Milano.

Sabrina Giannini ha avuto modo di ribadire il suo impegno e ha affermato: “Per cancellare definitivamente le reti derivanti credo fosse importante mostrare il vero volto dei pescatori che ne fanno uso, un volto diverso dallo stereotipo del bravo e povero pescatore che guadagna il necessario per la sopravvivenza. Si tratta di pescatori che si sono arricchiti, sprezzanti delle regole e dell’etica. Credo fosse ancora più grave la 'tolleranza' e la complicità dei politici del Sud Italia che per dieci anni hanno lasciato operare questi pescatori in una sostanziale impunità, a dispetto dei pescatori onesti e delle specie marine drammaticamente coinvolte. Da quando il servizio televisivo ha fatto emergere l’impunità di cui godevano questi pescatori, mi ha piacevolmente colpita il fatto che ci sia stata una diffusa presa di coscienza, anche da parte della politica e delle capitanerie coinvolte, che stanno eseguendo numerosi controlli e sequestri. Non so se e quanto durerà l’attuale situazione. Ho reso noto alle istituzioni italiane la mia intenzione a documentare questa situazione finché la pesca al pescespada continuerà ad essere fatta con l’uso delle reti derivanti. Potrebbe essere una guerra lunga, ma vale la pena combatterla e il vostro autorevole riconoscimento è un importante sostegno. Per questo ringrazio tutti voi”.

HOME by Yann Arthus-Bertrand

Yann Arthus-Bertrand became famous through the “Earth from above,” a photographic portrait of aerial shots of our planet. Three million copies of his book have been sold and his free, open-air exhibitions have been seen by more than one hundred million people.

The movie HOME carries on this tradition. This feature will be made up of aerial images which have been filmed in more than fifty countries around the world. A voice-off will offer constructive hindsight into the major environmental and social challenges facing our world.

The worldwide release of the movie will be organized by EuropaCorp on June 5th, 2009 – World Environment Day – in cinemas, on television, on DVD and on the Internet around the world. The aim of this simultaneous worldwide broadcasting is to enable as many people as possible to watch the movie together.

The objective of HOME is not to make a profit. Its only benefit will be to contribute towards increasing awareness of our responsibility towards the planet. Profits will be donated to Goodplanet.org

Artemis: life and death of a monk seal

Please find below a message by Dr. Spyros Kotomatas, Director of MOm, the Hellenic Society for the Protection of the Monk Seal.

---

Dear friends and colleagues,

With great disappointment and sorrow I would like, on behalf of all of us at MOm, to inform you that Artemis, the orphan monk seal pup rescued and treated by MOm for a 4 month period, and released in the core zone of the National Marine Park of Alonnisos Northern Sporades in Greece just over a month ago, was found dead on the 14th of May. Based on the results of the necropsy conducted the animal died of drowning, most probably due to entanglement in fishing gear.

Do find below the press release that we have just issued in relation to the particular case, that provides a detail account of the events and the up to date available information.

A sad last message from Artemis

On Thursday 14th of May, our organization received sad and disheartening news: orphaned monk seal pup ‘Artemis’ had been found dead at the port of Skiathos. Subsequent investigations, including the results of a necropsy performed by a veterinary pathologist from the Netherlands, indicate that she had drowned, most probably as a result of becoming entangled in fishing gear.

With a clean bill of health from her veterinarians, Artemis had been released just over a month ago, into the core zone of the National Marine Park of Alonnisos, Northern Sporades (NMPANS) — this following 4 months of treatment at MOm’s Monk Seal Rehabilitation Centre, that had raised her from a vulnerable week-old pup to a vigorous young seal.

After her body was discovered at Skiathos, events unfolded as follows:

- MOm’s response team recovered the carcass and, in collaboration with the local Port Police authorities, managed to transfer it to Athens that same evening.

- Prof. Dr. Thijs Kuiken, a veterinary pathologist specialising in marine mammals at Erasmus University, Rotterdam, travelled urgently to Greece to conduct a full necropsy at the zoology laboratory at the University of Athens. He was assisted by MOm’s own biologists, who are also experienced in performing monk seal necropsies.

- The necropsy established that Artemis was in excellent nutritional condition and overall health, having a normal weight for her age. There was clear evidence that the seal had died as a result of drowning.

“The results of the necropsy,” said Dr. Thijs Kuiken, “led to the clear conclusion that the animal died of acute pneumonic edema, caused by drowning. The fresh food remains identified in the stomach and the evidence of active digestion in the digestive tract substantiate further that death was sudden.”

To further assess the condition of the animal, additional data were utilized, obtained through the attached satellite tag (GPS mobile telephony tag), that recorded Artemis’ movements and behavior during her post-release monitoring, a program conducted by MOm in collaboration with the Sea Mammal Research Unit of UK. Artemis, up until her death, exhibited a gradual and continuously increasing mobility and diving ability, first around her release site and then outside the NMPANS, covering distances of more than 100 nautical miles, and with dives exceeding 150 meters in depth.

The specific conditions in which the death occurred, as well as the exact cause of drowning, may yet be determined through further in-depth analysis, both of samples from the necropsy, and satellite tag data from the last few hours prior to the animal’s death.

At this point, however, interpretation of the accumulated evidence suggests that Artemis may have drowned as a result of becoming entangled in fishing gear.

“Although the young seal quickly adjusted to its natural environment,” says Vangelis Paravas, Conservation and Policy Coordinator of MOm, “the harsh but unavoidable fact is that Artemis ultimately also had to face the reality of surviving in the wild, just as the rest of the remaining monk seals in the Mediterranean Sea.”

Data stemming from MOm’s long-term research — notably from its current European Commission LIFE-MOFI project, that investigates seal-fisheries interactions throughout the country — have shown that the entanglement of monk seals in fishing gear, and especially in nets, constitutes one of the most significant threats for the Greek population of the species, the largest in the EU.

This threat, occurring commonly during spring, is the main cause of death in immature monk seals. In fact, 47% of the mortality recorded in immature animals is attributable to entanglements.

As part of the MOFI project and in consultation with artisanal professional fishermen and their representatives, MOm is formulating specific proposals to the Greek government to mitigate monk seal mortality and promote sustainable coastal fisheries.

“Despite difficult and disappointing times like today,” says Dr. Spyros Kotomatas, Director of MOm, “monk seal rescue, treatment and rehabilitation remains a key priority for MOm in the conservation of Europe’s most endangered marine mammal.”

We will keep you informed of any further developments as they become available.

MOm, would like to thank all people, institutions and bodies that participated, assisted and supported the particular effort and express our commitment to continue with conviction the course towards achieving MOm’s mission to conserve the most critically endangered marine mammal in Europe and to protect the marine environment of Greece.

The End of the Line

A feature documentary film revealing the impact of overfishing on our oceans. The film shows firsthand the effects of our global love affair with fish as food.

It examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.

Filmed across the world – from the Straits of Gibraltar to the coasts of Senegal and Alaska to the Tokyo fish market – featuring top scientists, indigenous fishermen and fisheries enforcement officials, The End of the Line is a wake-up call to the world.

In the film's web site http://endoftheline.com/ you can preview excellent video shots, waiting for the film to be released.

The web site also allows you to claim your bit of ocean - it's a nice idea and a smart way of making the point.

Mediterranean region: ever drier by 2100

'A new study suggests that the impact of climate change on the Mediterranean region will change precipitation and evaporation rates over land and sea, creating even drier conditions. A greater amount of atmospheric moisture will be lost from the region. Agriculture may suffer as a result, and the salinity of the Mediterranean Sea could increase.
The study suggests that many of the projected changes will have started by 2020-2049, with further changes gradually intensifying until 2070-2099.
Long-term changes project a decrease in precipitation and an equal increase in evaporation over the Mediterranean Sea, making the sea increasingly saline: the degree of salinity will depend on the inflow of fresh water from the Atlantic Ocean through the Gibraltar Strait.

Sea lions and marine debris

The Alaska Department of Fish and Game with Sea Gypsy Research produced an educational video called ‘Entanglement of Steller sea lions in marine debris: identifying causes and finding solutions’.

The video describes how Steller sea lions (Eumetopias jubatus) become entangled and - most of the time - dye for this reason, which are the most common sources of entangling debris, and what one could do to help reduce the number of entanglements.

These animals are threatened because of us and unfortunately this problem is not only related to sea lions but affects any marine animals such as cetaceans, elasmobranchs, pinnipeds, sea-turtles, marine birds, and big fishes.

As the video says: “... Since many of us live near some types of waterway, enjoy eating seafood and use plastic materials, we all contribute to the problem... Let’s be part of the solution!”

Don't feed wild dolphins animation

What is a dolphin doing in front of a fireplace with a brown bear, a seagull, another dolphin and two racoons?

He is telling the others 'patients' about his problems, and how it all started...

“For me it started with one hit of sardines.
Oooh... Sardines.
That's when I learned to beg.
It was easy to score free fish.
I mean eh, with this dolphin smile... [clicks].
Yeah, it's illegal but no one cares.
I had a monkey on my back and I was "jonesing" for people food...
Hanging out under boats, dodging props and hooks, doing dangerous stuff that I'm ashamed to admit?
Look... I know that I can kick this, if people would just stop feeding me”.

This animated announcement was produced by a coalition of governmental agencies and private organisations. Through innovative communication, it reminds viewers that feeding wild dolphins or harassing them is illegal and harmful to both dolphins and humans.

New monk seal breeding colony in the Aegean Sea

An island previously reserved for military use turned out to be a safe heaven for the endangered Mediterranean monk seal. Three out of the eight caves are suitable for pupping and in 2004 ten pups were identified, four in 2005 and seven in 2007.

Being off limits for all but the military, the beaches of this island provided a safe place for mothers and pups to rest, a behavior that has not been observed in this species in the Mediterranean Sea recently.

This newly discovered colony, with relatively high natality compared to other breeding sites in the Mediterranean Sea and the rare use of open beaches, is of outstanding conservation value and is in urgent need of effective protection.

EU halts bluefin tuna fishery in the Mediterranean

The European Commission closed the industrial tuna fishing season early (June 16th as opposed to end of month), provoking a wave of protest from Europe's leading fishing nations. With quotas nearly full, and substantial illegal fishing reported again this year, the EU executive said that fishing in the Mediterranean and eastern Atlantic needed to be halted early to protect the species.

The move targets fishing by purse seiners, which account for 70% of all bluefin tuna hauls. Spanish ships are allowed to fish until June 23rd.

The commission said an early closure was all the more necessary this year because the purse seiner fleet had grown substantially since 2007 despite tougher international quotas and EU funds available for reducing fleets. "The commission is determined to use all necessary means to prevent a recurrence of the substantial overfishing seen in 2007" it said.

Illegal fishing for bluefin tuna is still rampant in the Med. Last week WWF and Greenpeace caught Italian planes spotting tuna schools from the air in the central Mediterranean. Spotter planes are illegal in the area, as they give too strong an advantage to a massive hi-tech fleet that is already far larger than the capacity recommended by scientists for the survival of the species and the fishery.

Since the Mediterranean tuna fishing season opened at the beginning of May, WWF calculated that over 10,000 breeding bluefin tunas were caught every day by the industrial fishing fleet.

Turtles in trouble

The Marine Conservation Society together with the Travel Foundation and design company Juniperblue have recently produced an entertaining and educational cartoon called Turtles in Trouble.

The 8 minutes long animation is for everybody planning holidays in the Mediterranean, but it includes valuable advice relevant to all destinations where marine turtles may lay eggs.

The video effectively shows how simple changes in our behaviour while on holidays can make a big difference. As the video points out: “Turtles are in danger of extinction, and extinction is forever. But doing your bit, you can give this spectacular animals the chance to survive for generations to come”.

Where have all the sharks gone?

Several species of sharks in the Med have almost disappeared, their numbers 97% below what they were 200 years ago.

This is the scary figure that emerges from a new research (Loss of large predatory sharks in the Mediterranean), founded in part by the Lenfest Ocean Program, just published on Conservation Biology.

Fishing (both direct and by catch), coastal degradation and lack of management, coupled with the life history of sharks (who grow slowly, mature late and produce few young) caused this massive loss.

Blue, thresher, mako, porbeagle and hammerhead sharks have almost totally vanished in catch records from all sorts of different sources (tuna traps records, coast guard, fishing market, recreational fishing tournaments data) over the years, the authors found.

The consequences on the ecosystem of losing these key players is still poorly understood, as populations of other fish and invertebrates shift in unpredictable ways. But the extent of this collapse "may hold serious implications for the entire marine ecosystem, greatly affecting food webs throughout this region,” said the lead author of the study, Francesco Ferretti, a doctoral student in marine biology at Dalhousie University in Nova Scotia.

Better management of shark fisheries is clearly needed to reverse this trend.

New publication on the Pelagos Sanctuary

Back in 1990, the Tethys Research Institute proposed to the “European Association Rotary for the Environment” a project for the establishment of a marine protected area, a Biosphere Reserve, in the high seas encompassing the most important habitat for cetaceans in the region.

The rationale behind the proposal, which was named “Project Pelagos”, included the ecological representativeness of the area, its high species diversity, its intense biological activity, the presence of critical habitat for a number of pelagic species including cetaceans, and the opportunities that the area offered to baseline research.

Now, almost 20 years later, the pioneer of Pelagos Giuseppe Notarbartolo di Sciara and other four authors published a comprehensive review on the Cetacean Sanctuary.

‘The Pelagos Sanctuary for Mediterranean marine mammals’ provides a description of the rationale behind the initial proposal and an overview of the challenging process leading to the creation of the Sanctuary, a unique area that contains habitat suitable for the breeding and feeding needs of the entire complement of cetacean species regularly found in the Mediterranean Sea.

Tuna conservationists attacked by Turkish fishermen

Three Turkish tuna fishing vessels surrounded the Greenpeace ship Arctic Sunrise while the crew of one of the vessels attacked the ship in the Cypriot Channel.

Earlier, Greenpeace flew its helicopter to document the activities of tuna fishing vessels. One of the three, the Cinar Ibrahim, collided with the Arctic Sunrise. The tuna ship’s crew then started hurling lead fishing weights at the Greenpeace ship. Gunfire was also heard. No one was injured but the Greenpeace helicopter was damaged and is now inoperable.

The Arctic Sunrise was sailing between Turkey and Cyprus to draw attention to tuna illegal overfishing.

MPAs export fish

MPAs export adult fish, egg and larvae to adjacent areas, as results of BIOMEX project (Assessment of BIOMass EXport from Marine Protected Areas and its impact on Fisheries in the western Mediterranean Sea) prove.

Depending on the MPA, the effect is on some species or groups of species. Fish biomass export varies greatly in space and intensity according to fish species, and is restricted to a small distance from MPA border, but it is likely to have positive effects on adjacent fisheries.

Fishing out the pirates of the Mediterranean

Greenpeace campaign "Defending Our Mediterranean" had barely begun when activists confronted Italian fishing “pirates” in the Ionian Sea and confiscated almost two kilometres of illegal driftnet containing dead undersized bluefin tuna and a small sea turtle that was later released alive.

The Greenpeace crew came across the Italian fishing vessel Diomede II, fishing with 8-10 km of driftnet in international waters approximately 50 kilometres off the coast of Sicily, Italy.

Diomede II - which is licensed only to fish with longline or anchored nets within 15 kilometres from the coast - was met at her home port by officials, alerted by the NGO, that confiscated its illegal driftnets.

EU tightens control on bluefin tuna fisheries

The European Commission launched a major control campaign aimed at preventing a repeat of last year's overfishing of Mediterranean bluefin tuna by a number of EU Member States.

The plan will bring together the resources of the seven main Member States involved in the fishery – Cyprus, France, Greece, Italy, Malta, Portugal and Spain – and will cover all stages in the market chain, including controls at sea, onshore, and at fattening farms.

The control campaign marks an unprecedented effort, in terms of both the scale of operations, and the technical means deployed. The Community Fisheries Control Agency will coordinate joint inspection and control activities involving 13 large patrol vessels, 36 coastal patrol vessels and 16 aircraft. There will be 14 campaigns at sea involving in all 30 inspectors, representing overall 160 patrol days. 25 joint inspections involving 50 inspectors are planned in the ports concerned. Commission inspectors will also be involved in 32 inspection visits both at sea and in ports.

As illustrated by a report published by the WWF, the whole fishery is plagued by overfishing by a fleet that keeps growing in size and efficiency - thanks also to 16 million Euro of EU fundings, as Oceana recently underlined.

EU funding for tuna overexploitation

Oceana – the international ocean conservation organisation – reports that millions of Euros have been allocated for the overexploitation of bluefin tuna in the Mediterranean, calls for the immediate closure of the Balearic fishing grounds, and criticises the contradictory measures adopted by implicated states.

According to Oceana, overcapacity in Mediterranean bluefin tuna fishery denounced by a WWF report (see 12 March post), has been financed by the EU with more than 16 million Euros. The EU purse seine fleets involved in this fishery are from Spain, France and Italy.

Oceana also stressed that management measures and actions by the governments participating in this kind of fishery do not correspond to the reality of the fleet and the state of bluefin tuna stocks.

Once again, scientific recommendations are being ignored. Excessive quotas are established, the fleets continue to fish in spawning grounds, undersized tunas are being caught, illegal vessels catch and land bluefin tuna in unauthorised ports, the fleets continue to ignore the assigned quotas and do not declare the catches.

Ships dumping waste: illegal as of 2009

Dumping of waste by ships in the Mediterranean Sea will become illegal as of May 1, 2009, the United Nations Environment Programme (UNEP) said.

The new rules prohibit the ditching of "all plastics, including but not limited to synthetic ropes, synthetic fishing nets and plastic garbage bags and all other garbage, including paper products, rags, glass, metal, bottles, crockery, dunnage (loose material used in ship storage), lining and packing materials".

The application of International Maritime Organization measures had been suspended for years, until adequate garbage collection facilities were established in ports around the sea's coasts.

Trawling near the coasts of Greece

Bottom trawling, a fishing method that drags a large net across the sea floor, is a known threat to the marine environment.

Due to the disruptive nature of this method, the European Regulation currently in force across the Mediterranean forbids trawling closer than 1.5 nautical miles from the seashore.

The Hellenic Centre for Marine Research has also demonstrated that trawling is the least selective of all fishing gears, with an annual bycatch rate up to 44%. The Greek Ministry for Rural Development and Food, in its National Operational Plan for Fisheries 2007-2013, acknowledges that “most benthopelagic species are in a state of relative overfishing or overfishing”.

Despite the European regulation and scientific evidence the Greek Ministry for Rural Development and Food, itself, has recently decided to allow the use of trawling nets at a distance of only 1 nautical mile from the coast.

A coalition of Greek conservation organizations, including Archelon, Mediterranean SOS Network, MOM, Pelagos Cetacean Research Institute, Greenpeace and WWF Greece, is calling for the immediate reversal of this decision, to prevent the destruction of coastal ecosystems and ensure sustainability of fishing in the long term.

Dolphins in a bottle

Giovanni Bearzi and other four researchers from the Tethys Research Institute recently published a paper reporting the work done in the Gulf of Amvrakikos during 2002-2005, resulting in the individual identification of 148 bottlenose dolphins.

This work shows that dolphin density and levels of site fidelity are high, and this was related primarily to prey availability, particularly of epipelagic schooling fish.

The importance of this semi-closed basin for bottlenose dolphins and other threatened species such as marine turtles and endangered birds supports the adoption of measures aimed to conserve its valuable ecosystems and raise the naturalistic profile of the area, while promoting environment-conscious development.

Paraphrasing the famous song by The Police, Dolphins in a Bottle sends a S.O.S. to the world to protect these unique animals and their environment, and we hope that someone gets it :-)

Rocky deserts at sea: causes and solutions

Many vegetated systems in temperate regions throughout the world may face dramatic ecosystems shifts to unvegetated states. So, flourishing kelp forests may become desolated bare rocky substrates void of the rich floras and faunas usually associated to forests.

In the Mediterranean there are no kelp forests, but rocky bottoms can be covered by macroalgae (e.g. Cystoseira spp) that host juvenile and adult stages of many invertebrate and fish species. The persistence of these macroalgal beds, that greatly contribute to maintain coastal biodiversity and productivity, is the result of a delicate equilibrium among environmental conditions, interactions among species and human disturbance.

In recent years it has been demonstrated that in Mediterranean rocky reefs where fishing is particularly intense fish predators may decrease in abundance and size. Their decreased predation impact on preys, including sea urchins (the most important grazers in such systems), may reflect in a dramatic increase of prey abundance.

The ultimate consequence of the fishing impact may thus be an increased grazing impact of sea urchins that causes the transition from macroalgal beds to the so-called ‘barrens’, that is bare rocks partially covered by encrusting coralline algae. They are a sort of rocky deserts.

How to cope with this? Management of complex natural systems is not easy because many processes may interact. Formation of barrens, for instance, can be also a consequence of other processes like water warming or sedimentation. However, fishing restrictions and fish predator recovery may be useful to reverse this phenomenon.

From this perspective, there is increasing evidence that the creation of effective Marine Protected Areas (and not paper parks) can allow fish predators to recover along with their potential in controlling sea urchin populations and their effects on macroalgae.

At the MPA of Torre Guaceto (SE Italy), in the same rocky reefs where in the past (before the establishment of the MPA) there were barrens, there are at present (after about 7-8 years of effective protection) more fish predators, less sea urchins and lower barren covers than outside the MPA, which is the proof that properly managed MPAs can allow the entire ecosystems to recover.

How climate influences the deep sea

Picture the Grand Canyon in Arizona - then place it under the sea: the Mediterranean seafloor is criss-crossed with deep submarine canyons that in sheer size put their land counterpart to shame. Rivers of dense waters flow through these canyons, their capacity varying depending on climate-induced phonomena.

During such an event, the amount of water transported in 4 months from the Gulf of Lion to the deep Western Mediterranean via the Cap de Creus canyon equalled 2 years of input from all rivers draining in the Mediterranean.

How these dense shelf water cascading in the Gulf de Lion affect the population of the deep sea shrimp Aristeus antennatus, the most valuable deep-sea living resource in the Mediterranean Sea, was recently discovered by Spanish researchers. Initially, the strong currents (up to 80 cm/sec) displace shrimp populations from the normal fishing grounds, producing a temporary fishing collapse. However, the food provided by the currents soon leads to a large increase in recruitment - which results in plentiful landings of large shrimps 3-5 years after major cascading events.

These new findings resolve the paradox of a long-overexploited fishery that has not collapsed after 70 years of intense deep-sea trawling. But climate change is expected to cause a decrease of winter deep water formation in the Gulf de Lion, which in turn could decrease the frequency and intensity of dense shelf water cascading events. Without this regenerative mechanism, fishery pressure could quickly deplete the stock of Aristeus antennatus and other valuable deep-sea living resources in the area.

Global MPA database

MPA Global Database is a project that aims to create a database on the existing Marine Protected Areas, worldwide.

Based largely on information in the World Database on Protected Areas (WDPA), the project has two main goals: to develop a more robust global MPA baseline than currently exists, and to develop alternative scenarios of global MPA networks using spatial modelling techniques.

MPA Global Database contains a great variety of information such as: names of MPAs for each country, area covered and year of designation, mean area of MPAs, percentage of MPAs located in a specific latitude etc.

This database shows that 4435 MPAs exist worldwide and they cover an area of 2.35 million km2. These numbers sound misleadinly big, but the fact is: only 0.65% of the world oceans is covered by MPAs!

Even more impressive is the estimate of global no-take areas (areas where fishing is banned). The percentage of world oceans subject to this specific regulation is only 0.08% !

This database is a new tool for the marine conservation and shows how much still needs to be done to protect marine biodiversity.

Bycaught dolphins washing up dead on British coasts

A scaring number of dolphins and porpoises are washing up dead on British coasts.

Since the beginning of the year, 29 animals have been found on the beaches of south-west England. Experts suspect that most have drowned after being caught up in fishing nets.

Some dolphins have their tails or beaks amputated probably due to a useless attempt to free them from the nets, in other individuals bellies have been sliced open after death to try to make them sink.

Mark Simmonds, science director at the Whale and Dolphin Conservation Society, said: "It is a horrid way for these dolphins to die and you can see that when they come ashore. Fishermen are getting more adept at hiding the evidence and what we see on land is only a proportion of the problem."

On the other hand, Andy Wheeler, from the Cornish Fish Producers' Organisation, said: "Every reasonable effort is made by fishermen to avoid bycatch of dolphins. The jury is still out on whether the level of bycatch is a threat to the population."

Considering that the fishing effort is increasing worldwide, it’s time to increase also our effort to eliminate bycaught animals, whether cetaceans, birds, marine turtles, sharks or others.

French driftnets killed by the European Court of Justice

Oceana, an international organization that works to protect and recover the oceans in the world, has announced that the European Court of Justice has refused to grant France exemption from the prohibition of the use of driftnets in the Mediterranean.

Driftnets used to catch bluefin tuna and swordfish were outlawed in the European Union from 2002 because they constitute a threat to the conservation of cetaceans, sea turtles and sharks. However, years after the ban entered into force, France and Italy have continued using driftnets. While operations in Italy have been downright illegal, the French fleet had taken advantage of legal loopholes to continue carrying out its activities, with full support from its government. French driftnets have caused significant mortality to striped dolphins in the waters of the Pelagos Sanctuary for Mediterranean cetaceans.

The European Court of Justice ruled that the French driftnet fleet should not have a temporary exemption from the ban as requested by its government. As such, France cannot offer the driftnet fleet its protection in 2008. Any fishing vessel using this gear to catch bluefin tuna must be sanctioned by French authorities.
