“…The SGR of the group treated with 360 g/kg protein was significantly lower than that of the groups treated with 420–480 g/kg protein. Similar results have been observed in grouper ( Epinephelus lanceolatus ♂ × Epinephelus fuscoguttatus ♀) (Jiang et al., ), Pacific threadfin ( Polydactylus sexfilis ) (Deng, Ju, Dominy, Murashige, & Wilson, ), totoaba ( Totoaba macdonaldi ) (Rueda‐López, Lazo, Reyes, & Viana, ) and red drum ( Sciaenops ocellatus ) (McGoogan & Gatlin, ). This was due to the insufficient amount of amino acids, especially essential amino acids, available to the fish when the dietary protein level was low.…”

This study was conducted to estimate the effects of dietary protein and lipid levels on the growth, body composition, gonadal development and activity of liver metabolic enzymes of the brown trout Salmo trutta fario broodstock. Ten diets were formulated containing five different protein levels (360, 390, 420, 450 and 480 g/kg) and two different lipid levels (90 and 180 g/kg). The experiment was a completely randomized 5 × 2 factorial design. The fish with an initial body weight of 462.53 ± 45.40 g were cultured in a spring water flow‐through system for 77 days. The growth performance was affected by dietary protein and lipid levels. Increase in the dietary protein and lipid resulted in increase in the body lipid and protein contents. The male gonadosomatic index decreased in the groups treated with relatively high levels of protein (390–480 g/kg). The activities of the hepatic amino acid‐catabolizing enzymes—alanine aminotransferase and aspartate aminotransferase—increased significantly with the increase in the dietary protein level. The activities of the lipogenic enzymes (fatty acid synthetase and glucose‐6‐phosphate dehydrogenase) and gluconeogenic enzyme (fructose‐1,6‐bisphosphatase) increased with the increase in the dietary protein level. Further, an increase in the activities of glycolytic enzyme in liver with an increase in the dietary lipid was observed. The variation in some intermediary metabolizing enzymes due to dietary components supports the high‐metabolic adaptability of this species to dietary protein and lipid levels. A diet with 450 g/kg protein and 90 g/kg lipid with 24.56 mg/kJ protein/energy ratio maximizes the growth, feed efficiency and gonadal development.

“…: grouper in juvenile stages, have a better growth in lower salinity while freshwater species have a better growth in higher salinity (Singhabun & Kummee, 2015). Nevertheless, our results are not agree with previous results in hybrid grouper whereby no significant effects of food consumption and growth are observed in different diet treatments (Jiang et al, 2015).…”

The influence of salinities and diet on growth performance of tiger grouper (Epinephelus fuscoguttatus) × giant grouper (E. lanceolatus) (TG×GG hybrid), was investigated. TG×GG hybrid (10.0 ± 0.5 cm initial length and 50.5 ± 2.0 gram initial weight) were subjected to different salinities (10, 15, 20, 25 and 30 part per thousand (ppt)) and two diets, commercial pellet (42% protein, 9% ash, 11% lipid, 9% moisture) or trash fish, Sardinella fimbriata (70%protein, 15%ash, 4%lipid, 76% moisture) in triplicates with 15 fish per replication. At the end of the experiment (60 days), the final length, weight, feed consumption (FC), feed conversion ratio (FCR) and specific growth rate (SGR) were calculated. The highest mean SGR (1.05± 0.02% BM day -1 , P<0.05) was observed in the 15 ppt + pellet group of fish, while the lowest SGR was observed in the 30 ppt + trash fish group (0.40 ± 0.05% BM day -1 , P<0.05). The highest FC was significantly (P<0.05) observed at 15 ppt on both diets. The lowest FCR (1.21± 0.15, P<0.05) was observed in the 15 ppt on pellet diet. The results denotes that 15 ppt fed with commercial pellet is the optimum condition for growth performance of TG×GG hybrid grouper juveniles.

ABSTRAKProtein merupakan nutrien yang sangat berperan dalam pertumbuhan ikan. Penelitian ini bertujuan mengetahui kebutuhan protein optimal untuk pertumbuhan ikan Tor tambroides dan pengaruh kandungan protein pakan terhadap efisiensi pakannya. Benih ikan Tor yang digunakan berukuran panjang (1,5 ± 0,1 cm) dan bobot (0,08 ± 0,01 g). Benih ikan dipelihara dalam akuarium berukuran 40 cm x 30 cm x 30 cm dengan ketinggian air 20 cm sebanyak 50 ekor. Selama 40 hari pemeliharaan benih ikan diberi pakan komersil berupa crumble dengan kandungan protein, (A) 25%, (B) 35%, dan (C) 50% sebanyak 20% per hari dari total biomassa ikan, pemberian pakan dengan frekuensi tiga kali sehari. Rancangan penelitian menggunakan rancangan acak lengkap dengan tiga perlakuan dan tiga ulangan. Hasil penelitian menunjukkan ikan Tor tambroides yang diberi pakan dengan kandungan protein sebesar 35% dan 50% memiliki pertumbuhan panjang, bobot, laju pertumbuhan harian (LPH), biomassa, nisbah konversi pakan (FCR), dan efisiensi pakan yang sama (P>0,05) dan berbeda nyata pada pakan dengan kandungan protein 25% (P<0,05).
