| Abstract: |
| Based on the data collected from the exploratory trawl fishing and environmental surveys in the western deep sea of the East China Sea in 1980-1981.this paper shown the relationship between deepsea fish distributions and oceanic conditions.The bottom environment is chiefly controlled by the Kuroshio and its branches.Generally,the temperature and salinity are high in the northwest and loov in the southeast of the survey waters,though their seasonal variations are very small.The diversity and stability of oceanic conditions lead to the complexity of the fish species and their distributions,and the distribution features have a close relationship with the vertical structure of the Kuroshio.In the case of different depths near the bottom,not only most of the fish species distributions are different but also the fish resource densities vary considerably.The concentrated areas of major species,such as yellow-fin filefish (Navodan xanehopttras) and deep-sea smelt (Glossanndon semifasciata)etc.,spread in the upwelling waters from the Kuroahio with more abundant zooplankton.The new fishing ground of yellow-fin file fish has been exploited in recent years and other fishing grounds will be available there. |
