Further experiments with radial escape section (RES) as fish-shrimp separator in trawl
(ICES CM Documents;1986/B:29, Working paper, 1986)A new approach to the bycatch problem when trawling for shrimp was initiated in Norway in 1984 utilizing the difference in swimming behaviour of fish and shrimp. A radial escape section (RES) in the aft belly of the ... -
In situ target strength observations on haddock
(ICES CM Documents;1986/B:39, Working paper, 1986)In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting ... -
Outflow of Skagerrak water to the North Sea during summer 1984
(ICES CM Documents;1985/C:21, Working paper, 1985)This paper describes a situation from summer 1984 where low salinity water from the Skagerrak was flowing west and north and covered a significant part of the northern North Sea Plateau. This unusually Skagerrak water ... -
