POPULATION STATUS AND DYNAMICS

Purpose: To better understand Dungeness crab biology, including spatial and temporal variation of larval crab abundance, characteristics of different life stages of crab, and controls on population growth and distribution.

Research Priorities:

  • Determine the best predictors of adult Dungeness crab abundance 

  • Identify population bottlenecks (e.g. spatial, temporal, life history)

  • Characterize mechanisms and extent of larval transport and distribution (see ongoing larval crab study)

  • Quantify basic information on biology and behavior to develop accurate stock assessments for Dungeness crab in inland Washington waters

  • Assess the male/female population structure

  • Investigate spatial and/or temporal variation in molting/mating

  • Determine the best way to use test fishery data in a predictive way
