Abstract

Eggs of Lithognathus mormyrus stripped from dead breeding fish are incubated and give larvae which are then reared to the fry stage. The yield of eggs depends on the freshness of the breeding fish. Survival of larvae is made possible by a natural bloom of ciliates, the duration of which depends on low initial larval density. In spite of a length of only 1.7 mm at hatching, growth is comparable with that of the sea bass. Fry adaptation to pellets is easy. Possibilities of mass production of fry with extensive rearing techniques are discussed. © 1983.
