Age determination, growth and maturity of the bleak Alburnus alburnus (L.) (Cyprinidae) in Lake Øyeren, SE Norway
Main Article Content
Abstract
Age, growth and maturity have been examined in bleak Alburnus alburnus (L.) collected in Lake Øyeren in 1975, 1976 and 1977. Otoliths were found to be more suitable than scales for age determination, while opercula were unsuitable. No difference in the growth of males and females of age 0 - IV could be detected in the material, and males have a shorter life span than females. Males and females reach sexual maturity at an age of 3 years. The spawning period is in June-July, and lasts for about one month.
