TOTAL HEMOCYTE COUNT AND HEMOLYMPH GLUCOSE CONCENRATION RESPONSE OF SPINY LOBSTER Panulirus homarus ON RATIO OF SHELTER

This research was conducted to assess the physiological response of the lobster Panulirus homarusfor the ratio of the shelters. The method used completely randomized design with two replicates of each treatments with shelter ratio (A) 1 : 5, (B) 3 : 5, (C) 4 : 5, (D) 5 : 5.Weight average for 18 4 lobsters with the stocking density of 23 lobsters for each treatment was 3 2 .64 ± 0.58 g. The experiment was conducted for 60 days. The lobster was fed with trash fish and acclimatized for 7 days before the experiment . O bservations on the physiologycal of every 10 days. The physiological responses that observed we re total hemocyte count (THC) and hemolymp h glucose concentration . The result s showed that 4:5 was the best lobster shelter ratio because it could reduc e stress leve ls . This is indicated by the stable values of THC and hemolymphglucose level during the experiment and supported by the growth of 57.28± 0.15 g and survival rate of 91.31±2.60%.   Keywords: lobster, Panulirus homarus , ratio, shelter, THC, glucose
