Mitigating Adverse Ecological impacts of open ocean fisheries
January 2013
Under the FP7, the EU DG Research has funded the research project MADE(Mitigating Adverse Ecological impacts of open ocean fisheries). The projectaimed at proposing measures to mitigate adverse impacts of fisheriestargeting large pelagic fish in the open ocean. Focusing on tropical tunapurse seiners using fish aggregating devices FADs and pelagic longliners, thegoal was achieved through the development of appropriate knowledge onthe behavioural ecology of species (with a particular focus on pelagic sharks), as well as on the fisheries themselves. The project gathered 13 partners from8 different countries (France, Spain, Portugal, Italy, Greece, Belgium, Brazil,Seychelles) and conducted research in the Indian and Atlantic oceans, as wellas in the Mediterranean Sea.This movie shows some aspects of the research that was developed under theMADE project to mitigate bycatch by pelagic longliners and tropical tunapurse seiners.

426 - Boom in jellyfish: overfishing called into question
March 2013
Will we soon be forced to eat jellyfish? Since the beginning of the 2000s, these gelatinous creatures have invaded many of the world's seas, like the Japan Sea, the Black Sea, the Mediterranean Sea, etc. Is it a cyclic phenomenon, caused by changes in marine currents or even global warming? Until now, the causes remained unknown. A new study conducted by IRD researchers and its partners, published in Bulletin of marine science, exposes overfishing as the main factor.
422 - Collapse of the false cod in Senegal: ineffective management of small-scale fisheries
January 2013
The waters off the coast of Senegal have been stripped of their false cods, also known as "thiof" or groupers. How is it possible that this country's iconic fish is nearly extinct? A French-Senegalese team recently demonstrated that the collapse of stocks is due to the boom in the small-scale fishery sector – generally viewed as a sustainable alternative to industrial fisheries. Over 30 years, the number of pirogues has quadrupled. Technological progress continuously improves the fishing power of the fleet. In order to reduce pressure on the resource, researchers recommend the implementation of a management system to control small-scale fisheries and regulate exportation, which pushes up prices per kilo and makes thiof a very profitable commodity, despite the scarcity of the fish.
