Effect of Dietary Vitamin E and C on the Reproduction Performance of Chinese Mitten Crab Eriocheir sinensis

摘要

Shrimp and crab aquaculture has grown impressively in many developing countries where this activity has attained great economic and social importance. A hairier to the development of shrimp and crab farming is an insufficient supply of seed, which ispresently gathered from natural sources. Thus, one of the most important and fundamental approaches to artificial seed production is to satisfy the ever-growing demand on crustacean bleeders to ensure a year-round supply of high-quality fertile eggs thatresult in high survival and growth rates, comparable to those occurring naturally (William and Addison 1990). For this purpose, the cultivation of broodstock that produce high-quality eggs is important. The nutrition of broodstock fishes and crustaceans plays a major role in achieving reproductive success and has a considerable influence on gonad maturation, fecundity, egg hatchability, and viability of larvae (Teshima and Kanazawa 1983; Watanabe et al. 1989; Bray and Lawrence 1992).
