| Research Abstract |
Larval transport and survival processes of white croaker, which has been recently decreasing, in Ariake Bay were studied by field samplings/measurements and numerical experiments. Several new findings were obtained, including a new genetic method for identification of white croaker larvae at the early stage, actual conditions of the spawning, larval distribution and transport, possible mechanism of the larval transport, and effects of prey availability and hypoxic water in the bottom water during the period of larval transport.
