A numerical simulation model of the population dynamics of walleye pollock, Theragra chalcogramma (Pallas 1811), in a simplified ecosystem. Part II. Model calibration, validation, and exercise

This report describes model calibration, validation, and results of simulation exercises using an age-structured energetics and population model of walleye pollock, Theragra chalcogramma (Pallas 1811), in a simplified Bering Sea ecosystem consisting of phytoplankton, copepods, and euphausiids. The model was described in detail in Knechtel and Bledsoe (1981). 1983 NMFS (National Marine Fisheries Service) NWFSC (Northwest Fisheries Science Center) AFSC (Alaska Fisheries Science Center) Library Public Domain 1864
