However, in recent years there has been a focus on implementing climate variability in the assessment ... -
Influence of climate on recruitment and migration of fish stocks in the North Sea
Svendsen, Einar; Aglen, Asgeir; Iversen, Svein A.; Skagen, Dankert W.; Smedstad, Odd M. (ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
