| The cooperative versus non-cooperative management of the South African west coast hake stock is explored using game theoretic modelling in conjunction with an age-structured model. The age-structured model is used to produce a physical flow account for input into national resource accounts. Between 1989 and 1998, the average catch of hake on the west coast was 92000 tons, most of which was harvested by the demersal trawl sector. The physical flow account indicates that the conservative re-building management strategy pursued for the fishery over the same time period mentioned above, has resulted in a 29% increase in the demersal trawl catch over the last decade. We simulated the effects of alternative quota restrictions on two fishing sectors (the... |
