Data from: Spatial variability in size at maturity of golden king crab (Lithodes aequispinus) and implications for fisheries management ...
Many crab fisheries around the world are managed by size, sex and season, where males are given at least one opportunity to reproduce before being harvested.

Many crab fisheries around the world are managed by size, sex and season, where males are given at least one opportunity to reproduce before being harvested. Golden king crab (Lithodes aequispinus) supports a commercial fishery in Southeast Alaska and legal size is based on growth and maturity information from other parts of their range. Size at maturity estimates varied for crabs among seven management areas in Southeast Alaska, where male maturity estimates increased in size with increases in latitude while maturity estimates across their North Pacific range decreased in size with increases in latitude. Depth, temperature, and harvest history were not related to variation observed in male maturity estimates. Management implications from this research include reducing legal size in some areas to maximize harvest potential and increasing in others to allow male crab the opportunity to reproduce before being harvested. A more conservative strategy would incorporate the largest maturity estimate thus, ... : SEAK_Male_SAM_DataMale size at maturity data collected for golden king crab (GKC) in Southeast, Alaska, which includes management area, carapace length (CL), and carapace width (CW).SEAK_Female_SAM_DataSize at maturity data for golden king crab collected in Southeast, Alaska, by management area, carapace length (CL), and female maturity.SEAK GKC tempTemperature data associated with golden king crab in Southeast Alaska, collected by management area, date, time, temperature reading.SEAK GKC DepthObserved depth of golden king crab captures in Southeast, Alaska.Male GKC legal spine lengthsMale golden king crab spine length data collected in Southeast, Alaska by management area.
