Product type Meeting

Edition 1

Synopsis (short abstract) We attempted the core fishing area approach and the new area effect concept incorporating environmental data, in order to evaluate standardized catch rates for Striped marlin (Tetrapturus audax) and Blue marlin (Makaira mazara) in the Indian Ocean. We used operatiol catch and effort data of the Japanese tu longline fisheries (1971-2012). We discussed pros and cons on the core fishing area approach and the new area effect concept by comparing results from last year.

Correlations between environmental factors and CPUEs of blue marlin (Makaira mazara) and striped marlin (Kajikia audax) caught by Taiwanese longline fishery in the Indian Ocean 2013

This study investigated the correlations between environmental factors (Indian Oscillation Index, Dipole Mode Index, Southern Oscillation Index, sheer currents, amplitude of the shear current, thermocline depth, and temperature at depth of 15/55m and temperature gradient at depth of 15/55m) and nomil CPUEs of blue marlin and striped marlin caught by Taiwanese longline fishery in the Indian Ocean. The results clearly showed that there are significant cycle-patterns between CPUEs and most environm ental factors. In addition, this study also suggested the environmental factors with the time-lags for CPUE standardization alyses of blue and striped marlins in the Indian Ocean.
