Fishing Techniques




This funnel-shaped net pocket or pulled by the trawler with warps (wireline). Panels help maintain the open under water trawl. Bottom trawling scrapes the seabed and fishing prawns, monkfish, cod, sole and squid. Note that this capture technique is the most used in the world and also dominant in the fishing port of Les Sables d’Olonne.



These are rectangular tablecloths mesh more or less broad set vertically in the bottom of the sea across the road from the fish by vessels called netters. The fish are taken by the gills. The net remains in place and is marked by floats. The net is pulled by the boat. This type of fishing is effective for sole, hake and anglerfish (monkfish).



The Danish and Scottish seine nets are composed of two wings, a body and a bag, the general design reminds in many ways of the trawl. Operated from the seiner, this machine is generally used on the bottom where it is hauled by two long ropes into the water to ensure the largest possible fish drives to the net opening. It captures many species of fish: mackerel, whiting, mullet, hake, ….



Also called “Pots” traps are traps. They consist of a rigid contoured mesh structure, and an opening: the chute. It (there may be several) is arranged so that the animal can enter the record but very difficult to come out. Laying traps is by sector, ie the bins are connected to each other and weighted for good rest on the bottom. A crab boat can ship into the water several hundred records.



These are long lines (main line, mother or mistress) which hang over the entire length of baited hooks (pieces of mackerel, sardines, mackerel, cuttlefish, squid, …). They are braced with two anchors and two buoys on the surface. They catch of groundfish species such as conger, skate, ling, bar or pelagic species such as tuna and swordfish.
