Larvae from several spawns were reared at a salinity of 31 and a temperature of 28°C. Yolk utilization rate, changes in body parameters and the development of morphological characters were observed. Maximum standard length (LS) and body depth were observed concurrently with yolk-sac exhaustion at 56 h postfertilization (hpf). A decrease in LS, body width and body depth was observed following yolk-sac exhaustion. Orbit pigmentation, followed by jaw articulation, were observed at 65 hpf. Substantial cranial and body cavity development occurred in the absence of visible yolk material. Complete absence of visible yolk-sac material and less than 2% of the oil globule volume at hatching were observed at the time of development of feeding ability. This indicates an absence of a transitional feeding period and the critical nature of first-feeding in this species within controlled environments10aEndogenous reserves10aLarval development10aRed snapper10aYolk utilization1 aWilliams, K.1 aPapanikos, N.1 aPhelps, R., P.1 aShardo, J., D.  uhttps://indiareeffishes.myspecies.info/node/171
