Cyclic nature of the male and female gonads compared to length of day and tempera- ture. (Gonadosomatic index = gonad weight (g) X 100/fish weight (g)) function for the developing embryos. After the first gill cleft is formed, the alimentary canal begins to function and desquamated cells, sperm, and blood cells are used as food (Turner 1938; Amoroso 1960). Vascularity increases and ramifies just beneath the epithelium of the ovarian wall and ovigerous sheets. The embryos are thus provided with both nutrition and oxygen from the epitheli- al lining (Wiebe 1968; Webb and Brett 1972). Presumably, toxic nitrogenous.
