A stripping method for Atlantic halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1987/F:40, Working paper, 1987)A stripping-board was built and tested on a broodstock of halibut ranging from 8 to 150 kg body weight. The smooth surface of the neophrene mattress minimized the loss of mucus and reduced the stripping stress ... -

Causes of variation in carcass traits of Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:25, Working paper, 1984)The aim of the present study was to reveal causes of variation in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon, composed of half sib and full sib groups, ... -
Coincidence echo statistics
(ICES CM Documents;1994/B:40, Working paper, 1994)Two scatterers at similar range give an echo which may appear to be due to a single scatterer. Methods for determining target strength that depend on resolving single scatterers may fail in this instance. Statistics associated ... -
Effects of fishing strategy on relative selectivity in trawls, longline and gillnets
(ICES CM Documents;1996/B:23, Working paper, 1996)Exploitation of fish stocks is dependent on effort, catchability, the selectivity of the gear used, and the fishermen's choice of time and place. A full-scale fishing experiment was conducted in February 1996 at the coast ... -

Size-selection of mackerel and saithe in purse seine
(ICES CM Documents;1994/B:28, Working paper, 1994)In purse seine fisheries, there may exist potentials for size selection because some of the fish in the catch are less than the legal size, and because different size groups are paid differently. Both potentials are ...
