    Transition from genetic to temperature-dependent sex determination in yellow catfish. A, Morphology and histology observations of yellow catfish with different genotypes. The gonad of 60 and 90 dph yellow catfish was fixed by Bouin’s solution (the top two panels), and H&E staining was carried out at 90 dph (two panels at the bottom, the lower panel was the magnification of the boxed regions). B, Statistics of sex ratios at 90 dph. The larvae of yellow catfish with XX and XY genotype were produced by XXm×XXf and YYm×XXf, respectively. One hundred fish of each group were selected randomly to count sex ratios by histology and morphology. Room temperature, 26–28.5°C.
