EVALUATION OF ACQUISITION, STOCKING AND SALE OF FISH IN A SPORTIVE FISHING ENTERPRISE

Abstract

The dynamics of the movement of fish was analyzed (acquisition, stock and sale) in a enterprise of sporting fishing or “fee fishing”. In the period understood between October of 1999 and December of 2003 monthly visits they were accomplished to an enterprise placed in the Road White Castle, in the State of São Paulo, Brazil, being made the rising of the data starting from you command them “of sale” and of the invoices of purchase of fish. They were obtained, for each one of the mentioned species, the amounts (in kilos) acquired by the fishing (entrance of fish) and for the customer-fishermen (exit of fish), whose number also enrolled. Such data allowed to determine the medium acquisition of fish for fishermen a month, to know the times of larger public frequency, the species preferred for acquisition, the biomass stocking in the pond, etc. The accompaniment showed that the practiced dynamics takes to the immobility capital, it puts in risk the sanitary safety of the fish population, and it turns the property a pollution exporter through pouring out water. The parameters for the selection the species, the handling techniques, as well as the incentives offered to the acquisition of the exemplary fish are insufficient, conspiring for the loss of profitability of the enterprise. The introduction with new fishes should obey the exit rhythm (fishing/sale) of the fish, being avoided to extrapolate the capacity supports of the pond. Therefore, one should not have the readiness of fishes for m3 as only incentive factor to the fishing, because that can take to an uncontrolled increase of the total population of the pond.
