Standardized CPUE of Pacific saury (Cololabis saira) caught by the Japanese stick-held dip net fishery up to 2023
We updated the standardized catch-per-unit-effort (CPUE) of Pacific saury caught by the Japanese stick-held dip net fishery up to 2023 for the stock assessment conducted by NPFC. CPUE was standardized 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 2023 was the second lowest since 1994 and the same level as in 2022.
