Preliminary review of experimental harvest rates in the depuration fishery for intertidal clams [electronic resource] / Graham E. Gillespie. Ottawa : Fisheries and Oceans Canada, 2000. 57 p. : fig., graphs, maps, tables.

This paper provides a preliminary review of results of the experimental harvest program in the depuration fishery for intertidal clams in B.C. Its objectives include: 1) To review survey results from eight beaches in the program, which began in 1996, through the surveys completed in the summer of 1999. This review includes discussion of quality of data from industry-conducted surveys. 2) To propose a management framework based on biologically-based reference points, with the objective of rebuilding stock size on over-harvested beaches, and providing threshold reference points for reduction in harvest rate as stock size decreases. This includes discussion of the quality of industry-estimated landings and the importance of recruitment to sustainable harvests. 3) To outline the implications of this review for depuration beaches harvested under a total allowable catch (TAC) management framework. gccst Fisheries resources gccst Molluscs gccst Fishing area gccst Fisheries management Canada.
