Evaluation of management performance of a new state-space model for pink salmon ( Oncorhynchus gorbuscha ) stock–recruitment analysis
A new state space stock –recruitment (SR) model (XSR) was developed to treat observation errors in spawner and catch data, and nonstationarity in productivity for pink salmon ( Oncorhynchus gorbuscha) . Closed loop simulation was used to evaluate the management performance of XSR and compare its per...
