The objective of this study was to generate information for the development of Isostichopus badionotus culture protocols by determining optimal spawning methods, egg production, length and duration of larval stages, and larval habitat settlement preferences. Studies performed during the spawning seasons of 2010 and 2011 showed that this organism spawns between July and November without mechanical or chemical induction. The larval development has five well-defined stages: early, mid and late auricularia, doliolaria, and pentactula. Juveniles (654.3 μm length) were obtained on average 25 days after fertilization (DAF), when larvae were incubated at 25 ± 1 C. No preference was observed for any of the materials used for settlement of the larvae. The easy adaptation of I. badionotus to the culture conditions and the competence of the larvae to complete metamorphosis while feeding solely on microalgae concentrates make this species an excellent candidate for farming. However, it is necessary to continue designing techniques for larval culture and to establish appropriate captivity conditions that allow multiannual reproduction.
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.
