State of the Med: the UNEP 2009 report

The UN Environment Programme (UNEP) Mediterranean Action Plan (MAP) and its Regional Activity Centres have released the first State of the Environment and Development report covering the Mediterranean region, which tackles key environmental issues, including climate change. The “State of the Environment and Development in the Mediterranean 2009″ was released during the 16th Meeting of the Contracting Parties to the Barcelona Convention, which took place from 3-5 November 2009, in Marrakech, Morocco.

The report is a pilot exercise, based on available sources of information and covers the 21 countries bordering the Mediterranean Sea. It finds that climate change is already occurring in the region and forecasts that it will lead to, inter alia, a decline in rainfall, increased periods of droughts and rises in sea-level. The report also identifies the most vulnerable Mediterranean zones and states that climate change will also affect agriculture and fishing, the attractiveness of tourism, coastal zones and infrastructure, and public health.

The Report

A new FAO treaty to crack down on illegal fishing

Rome, Nov 23 2009 - A new FAO treaty to fight illegal fishing - finalised by 91 countries - is now open for signature by member states. The agreement will legally enter into force after 25 countries have ratified it.

Officially known as the Agreement of Port State Measures to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated (IUU) Fishing, the treaty specifies minimum standards for inspection.

Under the terms of the text, foreign vessels will have to request permission in advance to dock at specially designated ports and will have to provide information on their catch. Signatories will also commit to regularly inspect fishing vessels in their ports according to a set of international standards. Port States will be obliged to prohibit entry to illegal fishing vessels.

So far the situation is not good: a research by the Pew Environment Group shows that while some vessels known to engage in IUU fishing are penalised by port authorities, many are entirely unaffected or simply manage to escape penalties by moving out of the convention area where they were listed.

Environmental groups estimate that one-fifth of all fish landed are caught illegally.

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.

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.

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.

Contaminants and marine megavertebrates - a workshop

'Contaminants and pathology in marine megavertebrates as environmental assessment tools' is the title of a workshop organized by University of Bologna on May, 8th, in Cesenatico, Italy. The meeting is organized in conjunction with Gruppo di Ricerca sui Grandi Vertebrati Pelagici.

Aim of the workshop is to focus on potential effects of pollutants on the health of marine megavertebrates. It will focus on different aspects of natural and anothropogenic pollutants and on suspected or proved connections with specific pathologies. Proceedings will be published on Endangered Species Research.

The workshop is open to students as well. Registration deadline is April, 30th.

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.

"Protected" marine protected areas are better than "just" marine protected areas

An obvious statement? Not so, as it seems. Many Mediterranean coastal states have established marine protected areas (MPAs), however more than 50% of these have no management plans and their regulations, particularly as far as fisheries are concerned, are not enforced. As a result, fish assemblages in these "paper parks" often cannot be distinguished from those found in non-protected waters.

Paolo Guidetti (University of Lecce, Italy) and colleagues have recently published (Biological Conservation, doi:10.1016/j.biocon.2007.12.013) results from research on fish assemblages simultaneously conducted across 15 Italian rocky shore MPAs within the framework of the "Sistema Afrodite" programme.

The authors discovered that only three of the marine reserves investigated had adequate enforcement, and that the degree of recovery of target fish species was tightly linked to the level of surveillance conducted in the MPAs. The study demonstrates the importance of including compliance among the factors considered in evaluating the conservation effectiveness of marine reserves, and warns that in careless analyses positive ecological responses in properly managed reserves can be masked by neutral or even negative results in paper parks.

How sharks find their next meal

Ever wondered how marine animals find their next meal?

Apparently, the same way we do our shopping: we don't wander aimlessly but go down the road and, if we don't find what we want, make a couple of longer trips downtown. This special type of random motion is known as a Levy walk.

Ecologist David Sims of the Marine Biological Association laboratory in Plymouth, U.K., and collegues have found evidence of Levy walks analyzing more than a million dives of 31 large marine predators - including sharks, fish, sea turtles and penguins - as they apparently hunted for food.

The team also conducted computer simulations showing that if prey is scattered in the ocean, but concentrated in clumps, repeated short dives with an occasional much longer plunge would be the best strategy to find it.

This research was published today on Nature.
