Estimation of maximum sustainable yield and maximum economic rent from the Philippine small pelagic fisheries uri icon

abstract

  • A method is presented whereby the fishing power of commercial fishing fleets and municipal fishing vessels can be standardized with respect to landed catches of small pelagic fishes in the Philippines. Fishing power was expressed as adjusted fleet horsepower (hp) and averaged over two years to account for the average life span of small pelagic fishes. The corresponding plot of landed catch vs fishing power was used to obtain a countrywide estimate of annual maximum sustainable yield for Philippine small pelagic fishes of 544,000 tonnes at an optimal fishing pressure of 256,000 hp. The yield curve indicates that presently, the Philippine small pelagic fisheries are heavily overfished and that since 1973, small pelagic landings have shown a declining trend. The maximum annual yield above costs was estimated to be about 500,000 t at a fishing effort of 155,000 hp or 35% of the present effort level. At current fish values, the maximum economic rent from the Philippine small pelagic fisheries would be about US$250 million
