By using harvest data for a North East Arctic Cod Fishery in the Barents Sea for the years 1971-1985 a monthly and
daily dimensional harvest function is estimated. The seasonal factors are investigated using dummy variables. The
results indicate that the seasonality is embodied in the catch ability coefficient of...
The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...
This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
