Preliminary Review of Experimental Harvest Rates in the Depuration Fishery for Intertidal ClamsMicroform - 2000
This paper reviews eight beaches managed experimentally in the depuration fishery for intertidal clams in British Columbia. The beaches were surveyed annually between 1997 and 1999, and total allowable catches were calculated by applying various harvest rates to the estimated legal biomass of Manila clams (Venerupis philippinarum). From the preliminary results, the paper draws conclusions regarding the existence of a single harvest rate that ensures sustainability for all beaches. The paper proposes a management framework using biologically based reference points. It also makes recommendations with regard to the harvest rates used in the current management framework, alternatives to constant harvest rate management, protocols for estimating total landed weight & species composition, and beach management.
