“…However, the feed effi ciency ratio in energy units (FER e ) is not affected by fi sh body water content, life stage, or trial period. (Kelso, 1972;Huisman, 1976;Verreth and den Bieman, 1987;Han et al, 2004). The proportion of feed energy used for excretion ranged from 5.22% to 6.08%, which was within the range of mean values of 5%-6.8% in other studies (Winberg, 1956;Brafi eld, 1985), but lower than that reported for brown trout (mean value of 8%) (Elliott, 1976).…”

We evaluated the effect of ration level (RL) on the growth and energy budget of lenok Brachymystax lenok . Juvenile lenok (initial mean body weight 3.06±0.13 g) were fed for 21 d at fi ve different ration levels: starvation, 2%, 3%, 4% bwd (body weight per day, based on initial mean values), and apparent satiation. Feed consumption, apparent digestibility, and growth were directly measured. Specifi c growth rates in terms of wet weight, dry weight, protein, and energy increased logarithmically with an increase in ration levels. The relationship between specifi c growth rate in terms of wet weight (SGR w , %/d) and RL (%) was characterized by a decelerating curve: SGR w =-1.417+3.166ln(RL+1). The apparent digestibility coeffi cients of energy exhibited a decreasing pattern with increasing ration level, and there was a signifi cant difference among different RLs. Body composition was signifi cantly affected by ration size. The relationship between feed effi ciency rate in terms of energy (FERe) and RL was: FERe=-14.167+23.793RL-3.367(RL) 2 , and the maximum FERe was observed at a 3.53% ration. The maintenance requirement for energy of juvenile lenok was 105.39 kJ BW (kg) -0.80 /d , the utilization effi ciency of DE for growth was 0.496. The energy budget equation at satiation was: 100IE=29.03FE+5.78(ZE+UE)+39.56 HE+25.63 RE, where IE is feed energy, FE is fecal energy, ZE+UE is excretory energy, HE is heat production, and RE is recovered energy. Our results suggest that the most suitable feeding rate for juvenile lenok aquaculture for wet weight growth is 2.89% bwd, whereas for energy growth, the suggested rate is 3.53% bwd at this growth stage.

ABSTRAKEvaluasi karakter pertumbuhan katak benggala stok Bali, Klaten, dan Sleman dilakukan untuk mencari kandidat populasi dasar. Pemijahan induk-induk katak benggala dilaksanakan secara fullsibs dari masing-masing stok dan percil yang diperoleh dipelihara selama 22 minggu. Pemeliharaan percil menggunakan bak beton berukuran 1x1x1 m 3 dengan kepadatan 75 ekor/ bak. Pakan berupa pelet terapung diberikan sebanyak 1,5%-3% per hari. Hasil pengamatan selama 22 minggu menunjukkan bahwa katak benggala stok Sleman merupakan kandidat untuk dimanfaatkan sebagai populasi dasar. Karakter fenotip spesifik katak benggala stok Sleman memiliki pertumbuhan bobot yang lebih cepat dibanding turunan Bali dan Klaten (P<0,05). Model populasi dalam karakter bobot relatif homogen, hal ini akan berdampak positif dalam menghasilkan individu katak benggala yang relatif seragam. ABSTRACT:Growth

The white shrimp (Litopenaeus vannamei) has been an important commercial shrimp species inIndonesia. This species is tolerance to low salinity therefore, it is important to develop its aquaculture. The purpose of this study was to study the effect of protein and calcium levels in diet on growth performance of the white shrimp post larvae. A factorial experiment at three levels of dietary protein (25, 35, 45%) and three levels of calcium (0, 2, 4%) ABSTRAKUdang vaname (Litopenaeus vannamei) merupakan jenis udang bernilai komersial penting di Indonesia. Spesies ini dapat hidup di salinitas rendah untuk itu perlu dikembangkan budidayanya. Penelitian ini dilaksanakan untuk mengetahui pengaruh protein dan kalsium pakan terhadap kinerja pertumbuhan pasca larva vaname. Disain faktorial digunakan dalam penelitian terdiri tiga tingkat protein (25, 35, 45%) dikombinasi dengan tiga tingkat kalsium (0, 2, 4%) dengan tiga ulangan digunakan dalam penelitian ini. Lima belas udang (PL 25) dimasukkan dalam 45 L akuarium. Salinitas dalam wadah adalah 2 ppt. Udang kemudian diberi pakan sekitar 8% dari bobot badan empat kali perhari. Percobaan dilaksanakan selama 28 hari. Parameter uji yang digunakan adalah laju pertumbuhan rerata harian, efisiensi pakan, rasio RNA/DNA, frekuensi ganti kulit, retensi kalsium dan protein. Hasil penelitian menunjukkan bahwa udang yang diberi kombinasi pakan mengandung 45% protein dan 2% kalsium menghasilkan laju pertumbuhan rerata harian, efisiensi pakan, rasio RNA/DNA, retensi protein lebih tinggi dibandingkan perlakuan lainnya. Kesimpulan diperoleh bahwa pasca larva vaname membutuhkan 45% protein dan 2% kalsium untuk pemeliharaan di kondisi media salinitas rendah.
