Relations between recruitment indices and occurence in cod stomachs of pre-recruits of cod and haddock in the Barents Sea
(PINRO-IMR Symposium, Conference object, 1995)The predation by North-East Arctic cod on pre-recruits of cod and haddock is reviewed based on data from the joint PINRO-IMR stomach content data base. It is investigated how the abundance indices from surveys of pre-recruits ... -
Relationship between survey indices of recruitment and VPA abundance estimates for North-East Arctic cod
(PINRO-IMR Symposium, Conference object, 1995)Survey estimates of abundance of recruiting and partially recruited age groups are important elements for tuning the VPA of north-east Arctic cod, both for estimating the present state of the stock and for future ... -
Relative selectivity in trawls, longline and gillnets on Greenland halibut
(PINRO-IMR Symposium, Conference object, 1997)Selectivity parameters for Greenland halibut (Reinhardtius hippoglossoides, Walbaum) are compared to catches reported fiom trawl, gillnets and longline in the Norwegian scientific fisheries for Greenland halibut. A trouser ... -

Sampling gear selectivity and its effect on estimates of mean length at age
(PINRO-IMR Symposium, Conference object, 1997)Using data fiom the Norwegian bottorn trawl surveys in the Barents Sea in February ( 1989- 1996), the International O-group surveys in the Barents Sea (1 985-1 996) and previously estimaied selectivity for the standard ... -

Schooling dynamics of spawning herring (Clupea harengus L.) in a bay in South-Western Norway
(PINRO-IMR Symposium, Conference object, 1997)The schooling dynamics of hening (Clupea harengta L.) was investigated during spawning in Raunefjord, south-westem Norway in 1994. A single school of Nonvegian spring spawning hening WSS) was tracked during daytime over ... -

Selection and survival in the Norwegian shrimp trawl fisheries
(PINRO-IMR Symposium, Conference object, 1997)Shrimp trawling has aiways been associated with large bycatches. The problems are solely due to the small mesh sizes generally used in shrimp trawl compared to mesh size in trawls used for various groundfish. During the ... -
Short note on abundance of SEBASTES Mentella in the 0-group and youngfish surveys as indicator of recruitment overfishing
(PINRO-IMR Symposium, Conference object, 1995)Abundance indices of 0-group Sebastes mentella from the international 0-group survey in the Barents Sea showed a sudden decrease from 1990 to 1991 to a low level which remained for three years. The strength of these weak ... -
Size- and species selection in Danish seine
(IMR/PINRO Joint Report Series, Conference object, 2001)The Norwegian seine fishery has traditionally been performed in relative shallow water close to the coast, and this as inevitable led to a high proportion of small fish in the catches. A work on size selectivity was therefore ... -
Some aspects of mortality, condition factors and liver state with Anisakis-infection in blue whiting in the North-east Atlantic
(PINRO-IMR Symposium, Conference object, 1990)Total mortality coefficients of blue whiting in the spawning area as well as in the feeding area, were obtained for various years and for various yearclasses, by calculating the regressions of the natural logarithms of ... -
