چکیده انگلیسی


• Four catch control devices were tested in the Barents Sea cod fishery.
• The devices with an acoustic releaser worked well but were expensive and required a lot of attention and time during fishing.
• The device with weak links worked well and was simple and inexpensive.
• The device with side splits also worked very well, was simple and inexpensive, and did not require attention between hauls.

Four catch control devices were tested in the Barents Sea cod fishery. Three of the devices were codends that close and partially detach from the rest of the trawl when they have filled up with the desired amount of fish. Each of these three systems had a different release mechanism (based on an acoustic releaser or a weak link). The fourth prototype was a codend with two side splits along the gear in the N-direction. For each prototype, the simplicity of the device, its cost, and its operational reliability in securing the desired catch size while releasing excess fish at fishing depth were evaluated.
