In stock assessment and fisheries management, the standardization of catch per unit effort (CPUE) is critical to derive an effective index of the abundance of exploited fish stocks. In addition to developing various statistical models, a method including the relative fishing power (RFP) of individual vessels has been developed from an intuition concept and applied to bottom trawl fisheries using logbookbased data. This is a convenient and traightforward approach for standardizing the catch-effort data of a fishery. The Pacific saury is a pelagic fish species, and its stock in the Northwest Pacific has been targeted by international fleets since the …

Maturity Characteristics Of Pacific Saury During Fishing Season In The Northwest Pacific, Wen-Bin Huang, Yu-Chun Huang
Journal of Marine Science and Technology
Pacific saury is a commercially important fish in the Northwest Pacific. This study examined the maturity characteristics, gonadosomatic index (GSI), condition factor (CF), and ovarian developmental stage of the saury stock in three months of the fishing season (from May to December) in the Northwest Pacific. The maturity characteristics of saury varied among these three months (May, July, and October) in 2009. In May, large GSI and CF values with advanced ovarian developmental stages but small knob lengths (KnL) and body weights (BW) were found. Also in this month, the large-sized saury (> 29 cm) possessed large GSI values and …
