Abstract
Egg development and morphological change of larvae of the Sakhalin sole Limanda sakhalinensis were studied by observing specimens obtained in a rearing experiment from fertilized eggs to the juvenile stage. The wild broodstock was collected in January 2010 and kept in a circular water tank (Ø1.5×1 m) at a temperature of 14.5±0.5℃. Fertilized eggs ranged from 0.72 to 0.82 mm (0.77±0.07 mm, mean±SD) in diameter. The eggs were spherical, transparent and adhesive demersal. The egg yolk was divided from the oocyte 10 min after fertilization (AF), and an embryo was formed in 36 h AF. More than 50% of the eggs hatched within 133 h AF. The mouth and anus did not open until 3.5±0.25 mm total length (TL). At 4, days after hatching (AH), the fish became larvae 3.7 to 4.2 mm (4.0±0.36 mm TL), yolk absorption was completed and the mouth began to open. The left eye moved upward and the nostril moved to the right at 39 days AH. These post-larvae ranged from 8.0 to 9.9 mm TL (8.9±1.33 mm TL). At 50 days AH, the fish became juveniles (12.4±1.20 mm TL) There were 70-72 dorsal fin rays, 55-56 anal fin rays, 11 pectoral fin rays, and 6 ventral fin rays and the juveniles adopted a benthic life.
