| Outline of Final Research Achievements |
The stocks of tuna species such as Pacific bluefin tuna, bigeye tuna and yellowfin tuna are recently decreasing. In order to maintain the abundance of tuna species, it is required to reveal the behaviour of tuna species. Therefore, we monitored the three-dimensional swimming behaviour of tuna species in the net cages and the purse seine nets using a stereo-video camera system and bio-logging technics. The environmental stimulations (light intensity, net shape, ambient depth, ambient temperature and water current) were also observed. Furthermore, we histologically determined the visual capabilities, which is predominant in tuna species. Based on these results, the integrated mathematical models for induced behaviour in response to the environmental stimulation in tuna species were established.
