Acoustic abundance estimates of the Icelandic stock of capelin, October 1978 - January 1980.
Vilhjálmsson, Hjálmar; Reynisson, Páll; Hamre, Johannes; Røttingen, Ingolf (ICES CM Documents;1980/H:63, Working paper, 1980)During the period October 1978 - January 1980 several estimates of the size and yearclass composition of the Icelandic capelin stock were obtained by the acoustic method. Surveying was carried out in October 1978, ... -
Acoustic abundance estimation of the Icelandic stock of capelin : 1978-1982
Vilhjálmsson, Hjálmar; Reynisson, Páll; Hamre, Johannes; Røttingen, Ingolf (Working paper, 1982)During the period October 1978 - february 1982 several abundance estimates and yearclass composition of the Icelandic capelin stock were obtained by acoustic methods.

The effects of a minimum landings size regulation in the fishery of Norwegian spring-spawning herring
Hamre, Johannes; Toresen, Reidar (ICES CM Documents;1986/H:51, Working paper, 1986)Effects of minimum landing size (LC) in the fishery of Norwegian spring-spawning herring have been investigated. The herring is assumed to be a unit stock, in which the growth of immatures differs according to the ... -
Effects of climate and stocks interactions on the yield of north-east arctic cod. Results from multispecies model run
Hamre, Johannes (ICES CM documents, Working paper, 2000)A conceptual climate dependent multispecies model for stock interactions and harvesting of herring, capelin and cod in the Norwegian Sea-Barents Sea region has been developed. The concept presupposes that good recruitment ... -

A model of estimating biological attachment of fish stocks to exclusive economic zones
Hamre, Johannes (ICES CM Documents;1993/D:43, Working paper, 1993)The paper describes a model of calculating indices of attachment of fish stock to fisheries zones based on biological parameters. Input data are weight by age, mortality rate and the percentage area distribution of an ... -
Observations on the Depth Range of tagged Bluefin Tuna (Thunnus thynnus L.) based on Pressure Marks on the Lea Tag
Hamre, Johannes (ICES CM Documents, Working paper, 1964)The present paper is an investigation on the depth range of tagged bluefin tuna based on pressure marks on the Lea tag (Figure 1). It was observed that the within season recaptures were without pressure marks, while the ... -
On the interpretation of the central zone in otoliths of capelin from the Barents Sea
Hamre, Johannes (ICES CM Documents;1977/H:37, Working paper, 1977)The present paper deals with biological aspects associated to the width of the central zone in capelin otoliths. It is found that the central zone represent the 0-group growth even in cases when the radius of the zone is ... -
