Abstrak

Lobster air tawar Cherax quadricarinatus (von Martens, 1868) merupakan komoditas budidaya yang bernilai ekonomis. Dalam budidaya terdapat beberapa kendala, antaralain harga pakan yang mahal karena pada umumnya sumber protein yang digunakan adalah tepung ikan sehingga diperlukan alternatif sumber protein lainnya untuk menggantikan tepung ikan. Tepung keong mas Pomacea canaliculata (Lamarck 1822) dapat dijadikan alternatif sumber protein karena mengandung 44,13% protein, 2,95% lemak dan 22,03% karbohidrat. Penelitiian ini bertujuan untuk mempelajari penggunaan tepung keong mas sebagai sumber protein untuk menggantikan tepung ikan pada pakan lobster air tawar. Dalam penelitian ini digunakan rancangan acak lengkap (RAL) yang terdiri dari 5 perlakuan, yaitu A(100% tepung ikan + 0% tepung keong mas) sebagai kontrol, B (75% tepung ikan + 25% tepung keong mas), C (50% tepung ikan + 50% tepung keong mas), D (25% tepung ikan + 75% tepung keong mas),dan E (0% tepung ikan + 100% tepung keong mas). Masing-masing perlakuan memiliki tiga ulangan. Hasil penelitian menunjukkan bahwa tepung keong mas dapat digunakan sebagai sumber protein untuk pakan lobster air tawar menggantikan tepung tepung ikan. Perlakuan B menghasilkan pertumbuhan yang lebih baik dibandingkan dengan perlakuan lainnya sehingga disarankan dapat diterapkan oleh pembudidaya. Kata kunci : Lobster air tawar, tepung keong mas, kandungan nutrisi tepung keong mas, pakan dan pertumbuhan. Freswater cryfish Cherax quadricarinatus (von Martens, 1868) is a cultured commodity that has economic value. In crayfish cultured there ase contrains such as expensive feed prices because generally the protein source is fish meal, so it needs alternative source of protein to substitute fish meal. The golden snail,Pomacea canaliculata (Lamarck 1822) meal can be an alternative source of protein because it contains 44.13% of protein, 2.95% of fat and 22.03% of carbohydrate. This reseach aimed to study the use of the golden snail meal as a protein source to substitute fish meal for crayfish feed. A completely rondomized design (CDR) was used with five treatment, i.e A (100% fish meal + 0% golden snail meal) as control, B(75% fish meal + 25% golden snail meal), C (50% fish meal + 50% golden snail meal), D (25% fish meal + 75% golden snail meal), and E (0% fish meal + 100% golden snail meal). Each treatment had three replication. The result showed that the golden snail meal could be used as a protein source for crayfish feed to substitute fish meal. The treatments of B leads to better growth, so it was advisable to be used by the farmer. Keywords: Crayfish, golden snail meal, nutritional content of golden snail meal, feed and growth.
