Starting from the year 2000, the European Union planned to establish the use of a selective trawl in brown shrimp (Crangon crangon) fisheries. In fact, the brown shrimp is caught by a bottom trawl equipped with stretched 20 mm exempted meshing in estuary areas where the nurseries of flat fish and gadidae are located. For Vilaine's estuary, Dupouy et al (1997) estimated at about 1 tonne of flat fish and one tonne of gadidae the loss in equivalent fish of marketable size, per landed tonne of brown shrimp. In this document, the authors introduce improvements resulting from the use of selective trawls developed in France (Asselin and Devismes trawls), and they show by what means the selectivity of these trawls can be improved further.

The impact of biotic factors such as density-dependent processes, recruitment, total mortality, and abiotic factors such as upwelling intensity, temperature and chlorophyll a concentration on the variation of growth parameters of pelagic and demersal fish were studied during the periods 1990 - 2008 (pelagic) and 1971 - 2015 (demersal). Life history parameters vary according to the species and from one region to another and over time within a given area because of their plasticity and the high fishing pressure. Interspecies and inter-regional comparison were carried out. Non-linear mixed effects models were used on different fish species of the Atlantic Ocean in order to estimate the growth parameters at the individual and population levels. Variations in...

Comment épargner les juvéniles de soles et de gadidés dans la pêcherie crevettière : expériences de chalut sélectif en baie de Vilaine, première partie

The French brown shrimp (Crangon crangon) fishery employs on a seasonal basis around 140 ships about 10 metres in length and with engines of about 100 kilowatts of power. It takes place mainly along the coastal bottoms of silted-up sand at a depth of 2 to 10 metres and occupies principally the coasts of the eastern English Channel and those of the Gulf of Gascony. The brown shrimp catch is performed by bottom trawl, with exempted meshing of 20 mm (stretched mesh), which causes numerous rejects of immature fish that live on the same bottoms. The main part of these juveniles is made up of flat fish (sole, in particular) and of gadidae (whiting and pout). To reduce these undesirable catches that are also detrimental to other fisheries, some ingenious...
