Much study has been done about larval ichthyofauna of inlets and estuaries along coasts of South Africa, Australia, Japan and the United States. These studies documented the importance of inlets and estuaries as nursery grounds for coastal fish larvae and juveniles. Although researches about the immigration of fish larvae and juveniles into inlets and estuaries were carried out in these areas mentioned above, little was known about immigration mechanism. The present study, conducted at Uranouchi Bay, being the largest inlet in Tosa Bay, intended to study the mechanism of immigration to inlets as fish nurseries. Three components of investigations were carried out, i.e. collections of fish larvae and juveniles using the inlet as nursery, capturing of immigrating fish larvae at the mouth part of inlet and acquirement of vertical distributions of fish larvae outside the inlet.
