MeetingCPUE standardization for bigeye tuna caught by Korean tuna longline fisheries in the Indian Ocean 2013

No results found.In this study, bigeye tu CPUE (catch per unit effort) standardization of Korean longline fisheries in the Indian Ocean was conducted by Generalized Linear Model (GLM) using operatiol data and aggregated data (1977-2012) to assess the proxy of the abundance index. The data used for GLM were catch (in number), effort (number of hooks) and number of hooks between floats (HBF) by year, month and area. In addition, we explored the core area where Korean tu longline vessels have been mainly fishing fo r bigeye tu. Bigeye tu CPUE was standardized for the whole area using both operatiol data and aggregated data and for the core area. All the CPUEs had decreased until the early of 2000s except a jump in the mid-1990s, and then showed a steady trend with a level of 2-3 in recent years. -
