Mortality and injuries of haddock (Melanogrammus aeglefinus) that are caught by pelagic longline
(ICES CM documents, Working paper, 2002)By-catches of haddock (Melanogrammus aeglefinus) below legal size (44 cm total length) in the seasonal pelagic longline fisheries for haddock off the coast of Finnmark, northern Norway, are often high. The small fish are ... -

Pelagic occurrence of Greenland halibut (Reinhardtius hippoglossoides) studied by means of vertical longlines
(ICES CM Documents;2004/K:69, Working paper, 2004)In order to calculate reliable survey indices it’s important to know the dynamics of vertical distribution of a fish species. The vertical distribution of Greenland halibut (Reinhardtius hippogolossoides) cannot be studied ... -

Review and evaluation of three mitigation measures - bird-scaring line, underwater setting and line shooter - to reduce seabird bycatch in the Norwegian longline fishery
(ICES CM documents, Working paper, 2000)Seabirds scavenge baits from the hooks of commercial longlines, resulting in incidental seabird mortality and bait loss. As interactions between seabirds and longline fishing may cause decline in seabird populations and ... -
Seleksjon og dødelighet i fløytlinefisket
(Fisken og havet, Research report, 1997)The bycatch of haddock (Melanogrammus aeglefinus) below legal size in the pelagic longline fisheries off the coast of Finnmark, Northern Norway, is sometimes very high. This project was aimed at reducing this bycatch by ... -
Size selective effects of a plastic body on longline hooks
(ICES CM Documents;1991/B:46, Working paper, 1991)The potential for improving size selectivity of longlines by using a plastic body attached to the hook shank was tested in a fishing trial for tusk (Brosme brosme), ling (Molva molva) and haddock (Melanogrammus aeglefinus). ... -
Swivel connected gangions in mechanized longlining - effect on cath rates and operation
(ICES CM Documents;1987/B:18, Working paper, 1987)Multifilament longline with swivel connection between gangions and mainline were compared with traditionally rigged gear on a vessel equipped with a mechanized longline system. The swivel-lines were adapted to the ... -
Synergistic effects of different baits on the same hook in the longline fishery for hake (Merluccius merluccius) and torsk (Brosme brosme)
(ICES CM Documents;1987/B:39, Working paper, 1987)The effects of a combination of different baits on the same hook were tested in two different situations. A bait combination of sardine (Sardina pilchardus) and mackerel (Scomber scombrus) was used to catch hake (Merluccius ... -
Testing of a new hook design in the longline fishery for tusk (Brosme brosme) and ling (Molva molva)
(ICES CM Documents;1987/B:20, Working paper, 1987)The EZ-Baiter Circle hook which is a hybrid design between the classical J- and Circle hook shapes, is developed to provide a more effective hook for use in mechanized longline systems. In comparative fishing trials, ... -
The Effect of Gangion Floats on Bait-loss and Catch Rates in Longlining
(ICES CM Documents;1984/B:8, Working paper, 1984)The use of gangion floats will expectedly reduces bait loss and increase catch rates in bottom longlining. Two floats of 5- and 8 g buoyancy are tested through flume tank experiments, underwater observations in the field ... -
