Abstract:
In this study, we tried to develop a theoretical framework based on the Schaefer model and establish bioeconometric models to estimate the index of fishery resources using cross-country macro data. The characteristics of our model are that we consider the effect of natural fluctuations of fishery resources over time (in other words, we assume not a steady-state equilibrium, but a state of disequilibrium) and differences in country. Our model indicated that Schaefer model, which has been applied to assess fishery resources in local fishery, can fit comfortably to the macro data in OECD countries. Our model need only an essential socioeconomic data in fishery and has a potential to supplement information on the status of resources in non-OECD or developing countries where scientific surveys are costly or may not be a workable option.
