In the Chiaochou Bay Paralichthys olivaceus lays eggs from near the end of April to that of May. The fertilized eggs was obtained from artificial fertiliza- tion on board. The incubation of eggs as well as the breeding of larvae and fing- erling were carried out in entirely static water. The larvae of Mussels, Rotifers and the Nauplii of Artemia salina constituted the main part of the food given them. Towards the later stages various zooplanktons were used in addition. Breeding in a large scale was made within the room in a cemented pond which contained 2 M~3 of water. There were two sets of nilon silk-bolting cloth net cage of 80×60×50 cm~3 in capacity were arranged, and 50 fish larvae per liter of water being put into each cage. The water temperature was 15--26℃ during the breeding experiment. The metamorphosed fingerling obtained after 32 days breeding amounted to 1,615 in number. The survival was 6.7 per cent.
