| 内容記述 | Vertical distribution of bigeye tuna and also their optimum water temperature were studied on the basis of experimental results of catches in both regular and deep tuna longline fisheries carried out in the Indian Ocean. Catch rate for the regular longline sharply increased towards the last situated layer between 141-160m where the maximum of 4.9 was recorded. The large catch rate was also found in the case of the deep longline at the depth below 200m; 7.4, 9.1 and 7.1-7.5 in the layers between 201-220m, 221-240m and 241-280m, respectively. The catch rate averaged over all temperature zone was 2.2 for the regular longline, and the catch rate became larger in the zone where the temperature lies within optimum water temperature reported for the bigeye tuna (10-16℃); 4.3 for 13-16℃ zone and 7.3 for 13-14℃ zone showing twofold and threefold, respectively larger than the average. For the deep longline, the averaged catch rate was 4.6, and the catch rate was 6.1 in the zone for optimum water temperature; considerably larger value of 7.4 was derived in the range between 11-14℃ zone. | |||||
