Abstract

Sand crab (Emerita sp.) is a marine biodiversity, but it has not been used as a fish feed ingredient. This study aimed to evaluate the nutritional value of sand crabs and to understand its effect when used as feed ingredient on the performance of Koi carp. The study was conducted in two steps, which is evaluation of the nutritional value of sand crab and its effect on fish performance. The proximate composition, amino acids, and fatty acids were measured using AOAC methods, and then the carotenoid content was determined by spectrophotometry. In the second step, the sand crab was added to fish feed at doses of 0, 5, 10, and 15 percent, and fed to koi fish for 42 days. The parameters observed were length gain (LG), weight gain (WG), and feed efficiency (FE). Nutritional data were analyzed by description and compared with fish feed ingredients from previous studies. Fish performance were analyzed by one-way ANOVA. When significant, Tukey’s significant mean test was applied. The result showed that the nutritional value of sand crab was comparable to other feed ingredients with a protein content of 37.88%, while carotenoid content was superior. The best performance of Koi carp was obtained with a dose of 15% sand crab in the diet, with LG, WG, and FE values of 0.93 ± 0.05 cm, 0.48 ± 0.06 g, and 63.50 ± 7.05 %, respectively. Based on this result, it can be concluded that sand crab has a high nutritional value and can be used up to 15% in Koi carp diet.

Abstract

Artemia merupakan pakan utama pada benih botia hingga umur tiga bulan sehingga substitusi Artemia sangat penting untuk pemeliharaan yang efisien. Penelitian ini bertujuan untuk menentukan rasio frekuensi Tubifex untuk mensubstitusi Artemia pada benih ikan botia. Benih botia yang digunakan berumur satu bulan dengan bobot 35-90 mg dan panjang 13-20 mm yang dipelihara dalam sistem resirkulasi selama delapan minggu hingga berumur tiga bulan. Desain penelitian adalah rancangan acak lengkap (RAL) faktorial dua faktor yaitu faktor kesatu merupakan kelas ukuran ikan S (35-54 mg), M (55-74 mg), L (75-94 mg) dan faktor kedua berupa lima rasio frekuensi substitusi Artemia: Tubifex dari A (4:0) yaitu 4 kali sehari untuk Artemia dan 0 kali sehari untuk Tubifex, B (3:1), C (2:2), D (1:3) dan E (0:4). Lima belas perlakuan interaksi dihasilkan dari kedua faktor yaitu SA (ukuran S; rasio frekuensi A), SB, SC, SD, SE, MA, MB, MC, MD, ME, LA, LB, LC, LD, dan LE diulang dua kali. Pengamatan dilakukan dengan mengukur pertumbuhan yaitu bobot, panjang total, serta sintasan. Parameter penunjang berupa kualitas air dan proksimat pakan. Data dianalisis statistik dilanjutkan uji Tukey. Hasil penelitian menunjukkan bahwa Tubifex dapat diberikan sebanyak 4 kali per hari pada seluruh kelas ukuran ikan tanpa pemberian Artemia.
