Abstract:Metamorphosing leptocephalous larvae of the bonefish (Albula sp.) were analyzed for total ninhydrinpositive substances (NPS) and free amino acids. Total NPS content showed little change during metamorphosis. The average NPS value (±S.E.) for 16 larvae was 1.8 (±0.1) mg×larva(-1), which represents approximately 4% and 8% of the total dry weight of early and advanced larvae, respectively. Taurine was the most abundant free amino acid in whole-larva extracts, accounting for 36% and 59% of the total by weight in e… Show more
scite is a Brooklyn-based startup 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 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.
