Surplus Production Models with Autocorrelated Errors

Abstract

In the present investigation, the surplus production models are fitted by incorporating error term with autoregressive of order one for the serially correlated catch-effort dataset from Gobindsagar reservoir. A comparative study among the various models is being possible for fish stock assessment of the above reservoir fisheries. The best model identified is, further, used to estimate the MSY value along with the optimum effort to achieve it.
