Exploitation rates and population size of cod in Placentia Bay, subdivision 3Ps : estimates from a new mark-recapture study / J. Brattey, N. Cardigan. : Fs70-1/1998-20E-PDF
This paper describes findings of a new mark-recapture study initiated in 1997. This study was designed to provide estimates of the exploitation rates on sub-components of the 3Ps cod stock, and in this paper we focus on the components of the stock inhabiting Placentia Bay. The study includes methods to estimate tag reporting rate, short-term tagging mortality, and short-term and long-term tag loss. We also develop a model that uses information on commercial catches and tag returns over time to estimate (1) overall exploitation rates on Placentia Bay cod associated with commercial fishing activity during 1997, and (2) population size of cod in Placentia Bay prior to the reopening of the commercial fishery in 1997.
