Fraser River Sockeye Fisheries and Fisheries Management - Cohen ...

estimates prior to 2001 are likely to be biased low due to under-reporting of commercialcatches in the sale slip system and deficiencies in catch monitoring efforts for FirstNation fisheries. The limited documentation for DFO catch monitoring program, fewestimates of precision, and minimal verification at landing sites for most Canadiancommercial fisheries (42% of the harvest) combine to leave substantial room forimprovement in the catch monitoring programs. Details regarding each of these fisheriesand the rationale for our evaluations of catch estimation methods are presented in thefollowing sections.Table 1 Annual estimates of the harvest of Fraser sockeye by Canadian and USfisheries, 1986-2009 (extracted from PSC annual reports).Canadian Fisheries US Fisheries TestYear Commercial First Nation Recreational Other Total Alaska Wash.
