Description

Data on estimated back-calculated body growth from both harvested and non-harvested populations of northern pike over 50 years along the Baltic Sea coast and in Lake Mälaren, Sweden. The aim is to study spatial and temporal variation in body growth, and especially how body growth relates to variation in water temperature. Data on surface water temperature from Kvädöfjärden (Batltic Sea) and Lake Mälaren during the study period. See detailed description of methods and analyses in the original article.
