Age determination and growth in the Tench Tinca tinca (L.) in Lake Jorkjenn, southern Norway
Main Article Content
Abstract
The age and growth of tench Tinca tinca (L.) collected from Lake Jorkjenn, southern Norway was investigated. Otoliths and opercular bones were found more suitable for age determination than scales. The maximum age was 18 years, higher than previously reported. This difference is explained by the use of different ageing techniques, and fishing pressure. Most important for the year-to-year variation in growth was found to be the mean air temperature in September since this may lead to an extension of the growth season.
