REARING OF SCALLOPED SPINY LOBSTER (Panulirus homarus) POST LARVAE IN FLOATING NET CAGE with different ARTIFICIAL DIET
Scalloped spiny lobster (Panulirus homarus) is an export commodity and high economic value in Asian-Pasific markets, but the wild population was already over fishing. The purpose of this study was to determine the best artificial feed for scalloped spiny lobster nursery in floating net cage.
The nursery were conducted using 9 floating net cage 1x1x1 m in size with four treatment and 3 replicates. Four different artificial diet were used as treatments, i.e.:
Pellet comertial for grouper (A), pellet comertial for shrimp (B), and pellet formula Gondol Institute of Mariculture Research and Development (IMRAD) (C). The stocking density of post larvae (total length 2.1 cm and body weight 0.28 g) was reared at 100 ind./cage. A complete random design was used as an experiment design. Data was analysed using ANOVA and descriptive statistics. Feeding times were twice a day at 08.00 and 15.00 at local time; wit dose 5% of biomass. The sampling of fry on nursery were conducted every month to measure of survival rate(SR), total length (TL) and body weight (BW). On the end of the experiment also take a sample of blood for haemocyte counting. The result of experiment during 4 month rearing show that there was not significant different (P>0.05) among treatments for growth of total length and body weight. The best survival rate was on treatment C with survival rate (39.0%), followed by treatment A (29.7%: and treatment B (16.7%). The number of haemocyte on the nursery was almost the same between treatments with haemocyte number about 250-285 x 103 per ml. From these results it can be concluded that artificial feed/pellet formula Gondol Institute of Mariculture Research and Development can be used for rearing of scallop spiny lobster post larvae.
