Development of a surplus production model applicable to British Columbia offshore stocks of lingcod (Ophiodon elongates) / by M. Cuif, M. AcAllister, and J.R. King. : Fs97-6/2861E

This species has been exploited offshore in four distinct areas since the development of the bottom trawl fishery in the 1940s. The last yield recommendations for B.C. offshore stocks were provided by King and Surry in 2000. The Total Allowable Catch limits have remained the same in the four areas since 1998 following the recommended yield options supplied by Leaman and McFarlane in 1997. Here, a Bayesian analysis of biological data was used to estimate the growth, length to weight conversion and maturity parameters for both sexes in the four areas. A state-space Schaefer production model was fitted to annual catch biomass from commercial and recreational fisheries and to several abundance index time series from commercial and scientific survey data.
