Research Abstract |
In the present study, we tried to create the basis for an optimum design for an offshore aquaculture facility for Pacific bluefin tuna (PBT) from not only mechanical aspects but also biological ones after considering the behavior of PBT. We used a numerical simulation system of the netting geometry developed by us to evaluate net deformation and the loads to the facility. The simulation results showed that the net cage was deformed and reduced to 50% of the original volume by current flow when the speed was 1 kt. The observation data obtained using a bio-telemetry system showed that the strong current blew up the net cage and caused a collision between the netting and the cultured tuna. In addition, the cold water mass acted as a strong constraint factor on the vertical swimming of PBT.
