Les métiers du filet fixe en France (Régions 1, 2 et 3)

This study provides some background on the set nets and the use of the gears. The various metiers using set nets are presented by region and maritime basin detailing the target species. The physical characteristics of nets (type, mesh), the number of vessels engaged in the activity, fishing areas, the amount of material used and the composition of the catch are inventoried by target species. Intraspecific selectivity for the main target species of set nets is examined in light of the available size composition of catches of turbot, brill, monkfish, pollack, red mullet, bass, common sole, rays, hake, spider crab, lobster. Few differences exist between the nets (single layer) and trammel nets except for the lobster. Minimum mesh sizes are suggested by target species, taking into account the above information and the average size of first maturity.
