内容記述 | Archival tagged immature Pacific bluefin tuna were released off Tsushima Island in the East China Sea. Time-series data on swimming depth, ambient temperature, internal body temperature, and light intensity were recorded every 128s to evaluate : 1) their vertical swimming patterns to depths below the thermocline and 2) the development of their diving performance with growth. In summer, the tuna spent most of their time at the surface, but occasionally dove to depths below the thermocline during the daytime, and at dawn and dusk. In addition, bluefin dove at increasing descent rates and surfaced more slowly when they made excursions to deeper depths. Larger-sized bluefin dove to much deeper depths than smaller individuals, suggesting that the diving performance of bluefin is related to their body size and larger size enables them to expand their vertical movement range. | |||||
