GROWTH AND SURVIVAL RATES OF DONKEY’S EAR ABALONE Haliotis asinina JUVENILES FED WITH DIFFERENT INCLUSION LEVELS OF DRIED Eucheuma

The experiment was conducted to determine the effects of different inclusion levels of Eucheuma spinosum in a commercial feed on the growth and survival of Haliotis asinina juveniles at Multi-Species Hatchery, College of Fisheries of the Mindanao State University Tawi-Tawi College of Technology and Oceanography, Sanga-Sanga, Bongao, Tawi-Tawi for the duration of 45 days using Completely Randomized Design (CRD). H. asinina juveniles were fed with commercial feed as negative control (0% dried E. spinosum, T1), 15% (T2), 30% (T3), 45% (T4) and 100% fresh E. spinosum as positive control (T5).

The final weight (FW), weight gain (WG), specific growth rate (SGR), final shell length (FSL), shell length gain (SLG) and survival rate of H. asinina juveniles in Treatment I, II, III and V were highly significant than in Treatment IV where there was total mortality (p<0.01). The highest weight gain (WG) of -6.85±1.8g, specific growth rate of -0.16±0.25% and survival rate of 33.39±3.9% were obtained from T1 followed by T2, T3 and T5 (p<0.01). These treatments were statistically similar (p<0.01). Therefore, the commercial diet with or without 15% E. spinosum could preferably be used as feed for Haliotis asinina juveniles
