a bag netâ hasâ a long vertical wall of netting, often several hundred metres long, running at right angles to the shoreline that is intended to interrupt the natural swim of the fish and direct them along it away from the shore and into a series of traps. it is usually a seasonal fishery when the target species are migrating or known to the moving close along the shorelines at certain times of the year. there will be some intertidal seabed disturbance when the gear is initially set out but this is in an already highly mobile area of the seabed.the bag net has however historically been blamed as having a contribution to the decreasing numbers of salmon and sea trout entering the uk river system. in uk this used to be traditional method of fishing for salmon and sea trout as they head for the river mouths to swim up the rivers to spawn. this fishing method has died out in most areas but in some places there are still the remnants of the poles from the bag nets on the shore.many migratory fish such as salmon and sea trout have a tendency to swim parallel to the shoreline as they move between feeding areas and spawning grounds.
when the fish come up against the ‘wall’ of netting they will turn and swim along it. as they swim in this direction they will encounter the ‘trap’ section of the bag net.these traps are similar to other fish traps in that the fish are easily directed into the trap but the escape is hard to find. on some of the larger versions of this gear the final trap can be sub divided by moving sections of netting or the netting floor lifted to trap the fish in a smaller section to make it easier to scoop them out.although there is not much of this type of fishing in the uk today there are many examples of this style of gear employed in the estuaries and shorelines in other countries. these are nets that are designed to be fixed to a beach or seabed to catch fish and guide them into a trap section. they are often used to capture fish as they migrate along a shoreline or up an estuary. they have a long vertical wall of netting, often several hundred metres long, running at right angles to the shoreline that is intended to interrupt the natural swim of the fish and direct them along it away from the shore and into a series of traps.
