abstract
A study was carried out to clarify the fish fauna of Kojima Bay in the Seto Inland Sea. The samples of the fish were collected monthly by the two Masu-ami (a small set net) and every other month by the Kogata-sokobiki-ami (a small trawl net) from September in 1976 to September in '77. The number of fishes collected was 11,292. They were classified into 62 species belonging to 39 families. Their scientific name as well as their abundance were described with their Japanese common name, the month of their appearance in the Bay. On the basis of seasonal occurrence and abundance, those fishes of Kojima Bay can be divided into the following three ecological categories.
(1) Year-round "residents"
(2) Temporary "visitors"
(3) Infrequent of accidental "visitors"
It was assumed that 20 species belonged to the year-round "residents", 11 species the temporary "visitors" and 31 species the infrequent of accidental "visitors" amongst the 62 species collected in the Bay.
