摘要: Cod Gadus morhua population in the Barents Sea was found to be spatially structured with regard length-at-age. Results were based on data collected during research surveys between 1982 and 1997. The identified spatial structure most pronounced for age groups 24 years decreased older higher potential migration. A positive linear correlation mean length-at-age geographical temperature established years. This shown strongest when temperatures 3 year periods ending of capture. follow gradient Sea. large part observed area effects could explained by variation areas. Evidence is also presented which indicates that predictability sensitivity dependence increases under extreme environmental conditions, i.e. northern eastern areas
