Abstract

Pengembangan budidaya lobster air tawar jenis Cherax quadricarinatus masih terbatas pada skala kecil. Pengetahuan terhadap domestikasi spesies krustasea tersebut masih terus dipelajari untuk mengembangkan budidaya secara luas, termasuk sosialisasi teknologinya. Salah satu faktor penting yang perlu diketahui untuk mendukung pengembangan budidaya adalah pakan ideal dalam menunjang pertumbuhan. Salah satu upaya yang dapat dilakukan dalam mengoptimalkan pertumbuhan lobster air tawar melalui pemberian pakan dalam bentuk segar dan secara konsisten. Penelitian ini bertujuan mengetahui jenis pakan segar yang dapat memberikan pertumbuhan tertinggi pada lobster air tawar. Penelitian ini terdiri dari 4 perlakuan jenis pakan segar yakni wortel, keong mas, cacing tanah dan ikan teri. Hasil penelitian menunjukkan bahwa pemberian pakan wortel, keong mas, cacing tanah, dan ikan teri menghasilkan pertambahan bobot individu sebesar 0,42; 0,38; 0,49; dan 0,11 g. Laju pertumbuhan harian secara berurut sebesar 0,40; 0,43; 0,69; 0,13%/hari. Hasil analisis menunjukkan bahwa bobot dan pertumbuhan lobster lebih tinggi (p<0.05) diperoleh pada perlakuan pakan cacing tanah (0,49 g dan 0,69%/hari). Kelangsungan hidup untuk semua perlakuan berkisar antara 68,75-87,50% (p>0.05). Penelitian menemukan jenis pakan segar dari cacing tanah Lumbricus rubellus yang menghasilkan respons pertumbuhan lobster air tawar yang tinggi.   Aquaculture of freshwater crayfish Cherax quadricarinatus, is still a small scale. Knowledge of the domestication of these crustacean species is still being studied to develop aquaculture widely, including the socialization of the technology. One important factor that needs to be known to support the development of aquaculture is the ideal feed to support growth. One of the efforts that can be done in optimizing the growth of freshwater crayfish is through the provision of fresh and consistent feed. This study aims to determine the type of fresh-feed that can provide the highest growth in freshwater crayfish. This study consisted of 4 treatments of fresh-feed, namely carrots, gold snails, earthworms and anchovies. The results showed that the feeding of carrots, gold snails, earthworms, and anchovies resulted in an individual weight gain of 0.42; 0.38; 0.49; and 0.11 g. The daily growth rate is 0.40 respectively; 0.43; 0.69; 0.13%/day. The results of the analysis showed that the higher weight and growth of lobster (p<0.05) was obtained in earthworm feed (0.49 g and 0.69%/day). Survival for all treatments ranged from 68.75-87.50% (p>0.05). Study found a type of fresh feed from the earthworm Lumbricus rubellus which resulted in a high growth response of freshwater crayfish.
