Rearing tank size effects feeding performance, growth, and survival of sergeant major, Abudefduf saxatilis, larvae
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2012, Vol 5, Issue 5
Abstract
This study examined the interplay between food and environment during larval rearing of the sergeant major (Abudefduf saxatilis) and potential constraints to aquaculture production. To address this objective, larvae were reared in two different size rearing tanks (60 and 120 L) and fed a diet of rotifers and size-sorted copepod dominated zooplankton. Prey-capture success was significantly lower in 60 L rearing tanks and larvae consumed significantly lower numbers of prey when compared to larger rearing tanks. Growth rates were significantly higher in 120 L rearing tanks. No larvae survived beyond 10 DPH in 60 L rearing tanks. The pattern of mortality observed in the 60 L tanks was attributed to poor preycapture performance generated by inappropriate rearing tank conditions.
