THE EFFECT OF FEEDING APPLE SNAILS ON THE GROWTH AND SURVIVAL OF SAND LOBSTER (Panulirus homarus)

Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian pakan keong mas terhadap pertumbuhan dan kelangsungan lobster pasir (Panulirus homarus). Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan perlakuan; Perlakuan P1 (100 % ikan rucah sebagai control), P2 (50 % ikan rucah + 50 % keong mas segar), P3 (50 % ikan rucah + 50 % keong mas olahan), P4 (100 % keong mas segar), P5 (100 % keong mas olahan). Data yang diperoleh dianalisa menggunakan analysis of variance (ANOVA) dengan taraf nyata 5 % dan dilakukan uji Duncan dengan taraf nyata 5 % untuk mengetahui perlakuan yang terbaik. Berdasarkan hasil penelitian menunjukkan bahwa semua perlakuan memberikan pengaruh yang berbeda nyata (p< 0.05) terhadap pertumbuhan mutlak, pertumbuhan spesifik, rasio konversi pakan dan efisiensi pakan. Pemberian pakan 100 % keong mas segar merupakan perlakuan yang paling baik dibandingkan dengan perlakuan yang lainnya. The aim of study was to determine    the effect of feeding apple snails on the growth and survival of sand lobster (panulirus homarus). The experiment used Completely Randomized Design with five  different treatments. The treatments were P1 (100% trash fish as control), P2 (50% trash fish + 50% fresh apple snail), P3 (50% trash fish + 50% processed apple snail), P4 (100% fresh apple snail), and P5 (100% processed apple snail). The data obtained were analyzed using analysis of variance (ANOVA) with a significant level of 5% and Duncan test was carried out with a significant level of 5% to find out the best treatment. Based on the results of the study showed that all treatments had a significantly different effect (p<0.05) on absolute growth, specific growth, feed conversion ratio and feed efficiency. Feeding 100% fresh apple snail is the best treatment compared to other treatments
