Survivorship and Growth Performance of Red Spiny Lobster Panulirus longipes longipes Reared in Floating Netcages Fed with Sardinella spp at Different Feeding Rates

Abstract

This study was conducted to determine the survivorship and growth performance of Panulirus longipeslongipes fed with Sardinella spp. in floating netcages at different feeding rates and to determine whichfeeding rate provides the best feed conversion ratio.Results showed that a feeding rate of 20% gave the highest growth (final average weight) followed by15% and 10% feeding rates, respectively. In terms of length increment, 20% feeding rate likewisepromoted the highest increment.Differences in feed conversion ratio among treatments was significant (P<0.05). Among the differenttreatments however, stocks fed at 15% body weight attained better growth increment and trend in feedconversion ratio.
