The effects of population density on the rate of growth, maturation, and productivity of the stock of the northeast Arctic cod Gadus morhua morhua

摘要

Multiterm dynamics of biomass, fishing mortality level, average weight of fish of various ages, and the rate of sexual maturation of cod Gadus morhua morhua of the northeastern Arctic population was considered. Hypotheses that explain a regular increase in the rate of cod growth and maturation were discussed. It was concluded that population density affects the rate of growth and the rate of sexual maturation of individuals.
