Summary: This study elucidates the molecular mechanisms of gonadal sex differentiation in tunas. In the female gonads, the expression of foxl2 and cyp19a1a induces ovarian differentiation, while in the male gonads, the upregulation of dmrt1 and gsdf promotes testicular differentiation. Androgen biosynthesis also plays a crucial role in male gonad differentiation.

Summary: This study investigated the reproductive traits of Pacific bluefin tuna in the Nansei Islands and waters off southwestern Honshu Island. The results showed that the distribution of spawning fish was influenced by sea surface temperatures, with a peak in late June. Mature female fish were widely distributed in the study area. The spawning fraction increased over time, and batch fecundity was positively affected by fork length and days since the start of the season.

Summary: This study investigated the effects of dietary L-ascorbyl-2-polyphosphate on juvenile hybrid grouper and found that supplementing with vitamin C improved growth performance and survival rates while reducing total feed intake. Hepatic VC concentration was positively correlated with dietary VC supplementation, reaching saturation at 386 mg/kg. Feeding diets without VC may lead to higher serum protein levels and skeletal deformities.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
