Preliminary results from tests using a high-frequency sonar as trawl-sonde
(ICES CM Documents;1986/B:37, Working paper, 1986)A high-frequency, short-range sonar is tested for trawl-geometry measurements on pelagic and bottom trawls. The sonar was operated on a standard, coaxial trawl sonde cable, and produced excellent images of the trawl ... -

Preliminary results of investigations on escapement of fish under the fishing line of a Norwegian sampling trawl
(ICES CM Documents;1986/B:30, Working paper, 1986)The Institute of Marine Research, Bergen, has carried out combined bottom trawl and acoustic surveys for cod and haddock in the Barents Sea and the Svalbard areas since 1981. These investigations have clearly demonstrated ... -
Preliminary results of Norwegian blue whiting survey northwest of Scotland in April 1979.
(ICES CM Documents;1979/H:33, Working paper, 1979)A brief report is given on the result from an acoustic survey with the R/V "Michael Sars'' to the blue whiting spawning area in second half of April 1979. Rather dense concentrations of blue whiting were found from west ... -

Preliminary results of the coalfish taggings 1954-58
(ICES CM Documents;1959/114, Working paper, 1959)From 1954 to 1958 more than 7 800 tagged coalfish were released, mainly in North Norway, of which about 2 600 recoveries have been reported. During the summer months the coalfish seem to be fairly stationary within ... -

Preliminary studies on the influence of bottom obstructions and topography on the availability of demersal fish for gillnet fishing in the North Sea.
(ICES CM Documents;1979/B:21, Working paper, 1979)Gillnet fishing experiments were carried out in the Little Fisher Bank area in the North Sea. Saithe and pollack and to some extent cod showed a patchy distribution along a gillnet string. The abundance of fish was ... -

Preliminary Tests of a Shrimp-fish Separator Section for Use in Shrimp Trawls
(ICES CM Documents;1984/B:12, Working paper, 1984)A prototype shrimp-fish separator to be installed between the body and codend of a shrimp trawl was designed and constructed. The separator uses large square meshes to provide an escape path for fish, while funnels ... -
Present ssatus of an intensive cod larvae rearing experiment at Austevoll
(ICES CM Documents;1981/F:13, Working paper, 1981)Cod yolk sac larvae were attempted start fed on natural plankton in plastic pens. The majority of the larval groups were also hatched in these pens. None of the sampled larvae had ingested feed, and all groups died out ... -
