Length, age and estimated back-calculated length of pike (Esox lucius) in relation to water temperature from Lake Mälaren and the Swedish Baltic Sea archipelago 1963-2019

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. Length and age of pike from monitoring and commercial fisheries. Data include estimated length at age of individuals from backcalculations of wingbones. Time series of monthly average surface water temperature during summer at Kvädöfjärden (Baltic Sea) and Lake Mälaren.
