| Abstract: | Summary The concentration of taurine within the ovary remains fairly stable during the different stages of oogenesis. However, there is a marked increase in the taurine level within the hepatopancreas during the terminal phase of vitellogenesis and this can be correlated with the metabolic needs of the oocytes. In view of the osmoregulatory role of taurine in Crustacea, and of the reduction in hydration of the ovaries that takes place before spawning, at the end of anecdysis, a relation taurine-reproduction-moult is suggested. |
