| 内容記述 | A serranid fish, Epinephelus akaara (TEMMINCK et SCHLEGEL), is an only commercially important species belonging to the genus Epinephelus in the Seto Inland Sea. The authors have carried out artificial fry propagation of this fish since 1965, and reported on the spawning habits observed in the culturing pond, egg development and larvae of early stages in the previous paper (UKAWA, HIGUCHI and MITo, 1966). In the present paper, the morphological characteristics of the larvae and young of this fish are described and also some notes on the rearing techniques and the ecology are presented. The successive developmental stages are shown in Figs. 2-10. The most characteristic feature of the larvae is extraordinary prolongation of dorsal 2nd and ventral spine. The ratio of these spine lengths to body length attains its maximum at the stage of 5-12 mm in total length, thereafter, it decreases rapidly with growth (Fig. 12). The rays of all fins are differentiated completely at a stage of about 12 mm in total length. The body is nearly transparent in alive, and pigment cells are less appeared until the stage of about 25 mm in total length, after this stage many melanophores and orange pigment cells develop rapidly all over the body surface, when the larvae change their habits from pelagic to benthic. It is difficult to denote the growth of the larvae because of the remarkable fructuation in growth among the larvae reared under the same conditions, however, they seem to attain 3.7 mm in total length within 7 days after hatching out, 6.2 mm in 13 days, 12.7 mm in 21 days, 24.5 mm in 25-26 days, 31.4 mm in 36 days, 49.4 mm in 45 days and 70 mm in 81 days. | |||||
