Standardized CPUE of Pacific saury (Cololabis saira) caught by the Japanese stick-held dip net fishery up to 2019

    We updated the standardized catch-per-unit-effort (CPUE) of Pacific saury caught by the Japanese stick-held dip net fishery up to 2019 for the stock assessment under the framework of NPFC. CPUE was explained by a generalized linear model (GLM) incorporating explanatory variables such as year, month, fishing area, vessel size, and sea surface temperature. The standardized CPUE in 2019 decreased to the lowest level since 1994.
