According to recommendations from the steering committee the work has focused on the following two main research areas: 1) To develop methods and equipment for identification of species and catch quality/size in a seine during hauling. The aim was to give the skipper tools to decide whether a catch should be slipped or kept at a stage of hauling where the fish is still viable if released. 2) to develop methods, equipment and procedures for lenient catch regulation from a seine set, with as little stress, physiological load and damage to released fish as possible. The aim was to give the skipper methods and equipment for releasing catch in a responsible manner if slipping is necessary. It is also a goal that the slipping procedure may be approved as a standard method by the authorities. Initially we tried to develop sampling methods based on permanent installations in the net and devices attached to it (i.e. bags built into the net walls and maneuverable landing nets), but with limited success. More successful is the development of a small sampling trawl that is shot into the seine with a line-thrower during net hauling, which was towed back to the vessel by using a small power block.
The main objective of this project has been to develop technologies and methods that reduce the extent of unaccounted mortality after crowding and slipping in purse seine fisheries for mackerel (Scomber scombrus) and herring (Clupea harengus).
