Surveying the younger age grows of saithe - experiences from a small scale acoustic survey at the coast of western Finnmark
(PINRO-IMR Symposium, Conference object, 1995)The small saithe (1- and 2- group) is mainly distributed in fairly shallow areas close to the Norwegian coast from Rogaland to eastern Finnmark. It is known to occur quite regularily at certain localities. It is usually ... -
Survival experiments with cod trawls: summer 2000
(IMR/PINRO Joint Report Series, Conference object, 2001)Survival trials with gadoid fish sorted out from a demersal trawl by sorting grids and mesh selection, were carried out in August 2000 off the coast of East Finnmark. The experiments offered no evidences that the sorting ... -

Survival of mackerel and saithe escaping through sorting grids in purse seines
(ICES CM Documents;1996/B:24, Working paper, 1996)Technology for efficient size-selection of mackerel and saithe in purse seines has been developed. A critical constraint for application of the technology is the survival of escaping fish. We have conducted a series of ... -
Survival of saithe (Pollachius virens L.) escaping through trawl meshes
(ICES CM Documents;1992/B:29, Working paper, 1992)A pilot study to estimate the survival of saithe escaping from a cod-end with 145 mm diamond meshes was done in April-May 1992 north of the Faroes. Escaped fish were collected in fine meshed net cages (2x2x5m aluminium ... -
Survival of tagged capelin (Mallotus villosus, Müller) and estimates of the 1974 spawning population in the Barents Sea from tag returns

Survival tests of internally tagged herring
(PINRO-IMR Symposium, Conference object, 1990)Two separate survival tests were run in an indoor basin. Herring was tagged applying internal metal tags as used in the annua1 tagging experiments on the Norwegian spring-spawners. The mortality caused by tagging was ... -
Sustainable yield estimates of the Barents sea capelig stock
(ICES CM Documents;1982/H:45, Working paper, 1982)The Barents Sea capelin suffer mass mortality after spawning. A model is developed to calculate the biomass of springspawners using previous autumn acoustic survey estimates of the total stock as input data. It is assumed ... -
Swell as a turbulence source in shallow water
(ICES CM documents, Working paper, 2005)Two field investigations in an exposed shallow area outside Lofoten, western Norway, were conducted in 1995 and 1996. Direct measurements of turbulence were conducted from an underwater tower with acoustic current meters ... -
Swept area variation with depth and its influence on stratified trawl surveys indices on Arcto-Norwegian cod
(ICES CM Documents;1986/D:18, Working paper, 1986)Stratified trawl surveys have been carried out in the Barents Sea and the Svalbard areas since 1981. Based on the assumption of a constant area swept by the trawl during a standard trawl haul at any depth, swept area ... -
Swimming behaviour of fish schools in the North Sea during acoustic surveying and pelagic sampling trawling
(ICES CM Documents;1990/B:38, Working paper, 1990)Swimming behaviour of schooling herring, mackerel and sprat, when approached by a survey vessel, was observed by aid of a true motion sonar. Observations were made both during surveying and during pelagic trawling. Horizontal ... -
Swimming speed of spent Norwegian spring spawning herring
(ICES CM Documents;1991/H:9, Working paper, 1991)In March 1990 spent Norwegian spring spawning herring were tagged on the spawning grounds off Karmøy in southwestern Norway. 37 of these tagged herring were recaptured approximately 40 hours later. The recapture took place ... -
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 ... -
Systematic bias in estimates of reproductive potential of cod stocks: implications for stock/recruit theory and management
(ICES CM documents, Working paper, 2005)Stock/recruit relationships, describing the relationship between the parental population and the number of offspring produced, are a central tool in population ecology. For fish populations the stock/recruit relationship ...
