Studies on the growth rate of grass carp, Ctenopharyngodon idella Val., fed on the leaves of two terrestrial fodder plants, lucerne, Medicago sativa L., and drumstick, Moringa pterygosperma, were carried out in cement cisterns. The grass carp had gained ah average net weight of 177g and 111 g with an overall specific growth rate of 3-17 and 2-78% per day when fed on lucerne and drumstick leaves respectively in a period of 120 days. Feed conversion ratios were 13-9:1 in lucerne as against 10-2:1 in drumstick leaves. The percentage acceptance of drumstick leaves as feed was lower than lucerne. However, superior feed conversion was observed in fish fed on drumstick leaves. The average net production of grass carp fed on lucerne was higher than the drumstick leaves. Fish fed on drumstick leaves, however, gave better economical returns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
