<p>ABSTRACT</p><p><br />This experiment was conducted to evaluate the use of by product of corn ethanol industry, DDGS (distiller dried grain with soluble) and hominy as feed raw material on digestibility and the growth performance of humpback grouper Cromileptes altivelis juvenile. Three experimental diets containing isoprotein (48%) but different in DDGS contain were used. Diet A containing 0% of DDGS and hominy while diet B and C containing 10.13% (6.13% of DDGS and 4% of hominy) and 19.05% (15.05% of DDGS and 4% of hominy). Reduce of fish meal level in the diet was happen as a consequence of balancing amino acid. For digestibility experiment and Cr2O3 at level of 0.05% was used as a tracer. The feces were daily collected 30‒60 minutes after feeding for 14 days. Dry matter and protein were used as digestibility parameters. Completely randomized design with three treatments and two replicates was used in this experiment. Humpback grouper with an average weight of 11‒14 g were reared at floating net cages (FNG) of 3×2×1.5 m3. The stocking density for each cage was 167 fish/FNG and reared for six months. For digestibility measurement 30 fish were held in cylindrical fiber tank filled with 800 L of sea water. Fish were fed three times daily at satiation level. For maintaining net in a clean condition net was changed in every ten days. Feed consumption, digestibility of protein and total, growth performance indicator i,e specific growth rate, feed efficiency protein and lipid retention were used as evaluating parameters. The results showed that the fish fed with diet containing DDGS (6.13%) dan hominy (4%), at the level of 10.13% (diet B), shows similar growth performance indicators with the fish fed diet A (0% of DDGS and hominy) and the growth performance indicator was higher when being compared to those fish fed diet C (containing 19.05% of DDGS (15.05%) and hominy (4%)) (p&lt;0.05). More over the inclusion of DDGS and hominy at the level of 10,13% give no negatif impact to feed palatability (shown by total feed consumption value) and digestibility of protein. The increasing level of DDGS and hominy more than 10% reduced palatability and protein digestibility. Based on this research, DDGS and hominy can be used up to 10% in the feed formulation of humpback grouper</p><p><br />Keywords: digestibility, growth performance, DDGS, hominy, humpback grouper, Cromileptes altivelis</p><p><br />ABSTRAK</p><p><br />Penelitian ini dilakukan untuk mengevaluasi pemanfaatan limbah jagung dari industri etanol dalam bentuk distillate dried grain with soluble (DDGS) dan homini sebagai bahan baku pakan terhadap kinerja pertumbuhan ikan kerapu bebek Cromiliptes altivelis. Ikan yang digunakan dalam penelitian ini adalah juvenil ikan kerapu bebek berukuran 11‒14 g. Ikan dipelihara dalam karamba jaring apung yang berukuran 3×1,5×2 m3 dengan kepadatan 167 ekor/jaring. Ikan diberi pakan sampai kenyang sebanyak dua kali sehari. Untuk menjaga agar jaring tetap bersih maka dilakukan pergantian jaring setiap satu sampai dua minggu sekali. Ikan dipelihara selama lima bulan dan setiap bulan dilakukan sampling. Tiga macam pakan digunakan dalam penelitian ini dengan kadar protein 47% dan rasio energi protein 10 kkal/g protein. Pakan A adalah pakan yang tidak mengandung DDGS dan homini, pakan B mengandung DDGS 6,13% dan 4% (total 10,13%), dan pakan C mengandung DDGS 15,05% dan Homini 4% (total 19,5%). Untuk mengevaluasi ketercernaan nutrien maka kromium oksida (Cr2O3) digunakan sebagai penelusur. Penelitian ketercernaan dilakukan di laboratorium dengan menggunakan fiber dengan volume 800 L. Rancangan acak lengkap dengan tiga perlakuan dan dua ulangan digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa nilai ketercernaan nutrien tidak berbeda sampai total kadar DDGS dan homini 10,13% (pakan B) dan peningkatan DDGS serta homini sampai 19,05% (pakan C) menurunkan nilai ketercernaan. Ikan yang diberi pakan dengan DDGS sebesar 10,13% (pakan B) memiliki nilai efisiensi pakan, sintasan, laju pertumbuhan spesifik, konsumsi pakan dan retensi protein yang sama dengan pakan tanpa DDGS (pakan A), akan tetapi nilai-nilai tersebut lebih tinggi jika dibandingkan dengan ikan yang diberi pakan B (p&lt;0,05). Retensi lemak ikan yang diberi pakan B memiliki nilai yang lebih tinggi jika dibandingkan dengan ikan yang diberi pakan A dan C. Dari penelitian ini dapat disimpulkan bahwa DDGS dan homini dapat digunakan sebagai bahan baku pakan ikan kerapu bebek sampai level 10,13% (DDGS 6,13% dan homini 4%).<br /><br />Kata kunci: pertumbuhan, ketercernaan, DDGS, homini, ikan kerapu bebek, Cromileptes altivelis</p>

Fulfill needs of Siamese gourami still rely on the catch from nature, so the population in nature has become decreased. The increase of Siamese gourami fish production from culture is still constrained by the survival rate and slow growth rate in the seed phase. The purpose of this research was to determine the effect of Siamese gourami stocking density on the application of optimum temperature and salinity to growth performance for optimization of production capacity. Application of optimum temperature and salinity refers to the results of previous research, i.e., temperature of 28 °C and salinity 3 ‰. Siamese gourami seed with length of 2.96 ± 0.42 cm and weight of 5.27 ± 0.10 g used in the research. The experimental design used completely randomized design with four treatments, i.e. 1 fish L-1, 2 fish L-1, 3 fish L-1 and 4 fish L-1. The results showed that there were an effect of different stocking density on absolute growth weight and length, survival rate, specific growth rate and productivity. This is shown in the C treatment which growth was 4.95 ± 0.037 g, length 3.51 ± 0.01 cm, survival rate 93.47%, specific growth rate 1.22% and fish productivity of 625.76 g.

The effect of stocking density on growth performance and survival rate of endangered Labeo bata, was conducted in nursery ponds from 14th June to 13th August, 2013. Three different stocking densities viz. 500, 600 and 700 piece-1 decimal were assigned as treatment T1, T2 and T3, respectively. The initial average weight of L. bata was 0.15±008 g. Hatchlings in all the nursery ponds were fed indigenous feed (26.95% crude protein) for 8 weeks. Temperature, ammonia nitrogen, pH had no significant differences (P<0.05). Final weight (g) was found to be the highest (4.06±0.06) in T1 and the lowest (3.20±0.03) in T3. The mean values of weight gain (g) was the highest (3.91±0.06) in T1 and the lowest (3.05±0.03) in T3. SGR was highest (5.49±0.02) in T1 and lowest (5.09±0.02) in T3. Yet again, survival rate was highest (70.33±0.88) in T1 where stocking density was the lowest among those aforementioned three treatments and lowest (61.00±0.58) in T3 where the stocking density was the highest among the treatments. And finally production (kg-1ha) was found highest (352.66±4.42) in T1 and lowest (337.50±3.19) in T3. Rearing of the Labeo bata fry in those three different stocking densities showed significant (p<0.05) variation both in highest survival and growth performance. Overall production of L. bata in treatment T1 was significantly higher than that of the other two treatments T2 and T3. Despite of this, consistently higher CBR was found from treatments T1 (1:1.78) than from treatment T2 (1:1.25) and T3 (1:1.06).J. Environ. Sci. & Natural Resources, 9(1): 67-73 2016

A trial involving a total of 56 weanling pigs was conducted to investigate the effects of including dark (Tower) and yellow (R500) rapeseed hulls, soybean hulls and a purified fiber source (Celufil) as 10% of the diets of starter pigs. The animals were offered the experimental diets from 5 to 9 wk of age. The pigs fed on the R500 hull diet had lower (P < 0.05) average weight gain (273 g/day) and feed consumption (481 g/day) values than those fed the other diets, which ranged from 400 to 466 g/day and from 755 to 882 g/day, respectively. The feed efficiency (gain:feed) values were similar for all dietary treatments with values ranging from 0.53 to 0.57. The lower feed consumption observed for the R500 hull diet was suspected to be due to poor palatability of these hulls probably caused by some hydrolytic products of glucosinolates. The dry matter, energy and protein digestibility coefficients for both rapeseed hull diets were similar. The R500 rapeseed hull diet had higher (P < 0.05) digestibility values for dry matter, energy and protein than the soybean hull diet while the Tower rapeseed and soybean hull diets had similar digestibility values for these components. The Celufil diet had similar dry matter and energy digestibility values with the SBH diet but the protein digestibility value for Celufil was higher (P < 0.05) than that of the soybean hull diet and similar to those of the rapeseed hull diets. The crude fiber digestibility values were similar for all diets. Key words: Dark and yellow rapeseed, hulls, fiber, growth performance, digestibility, swine

<p>This study was conducted to determine the effects of inorganic selenium (sodium selenite) and organic selenium (selenomethionine) supplementation on growth and viability of juvenile humpback grouper (Cromileptes altivelis). The experiment was designed as a completely randomized design with eight treatments and three replications. The treatment being tested was source and dosages of selenium ie., inorganic selenium (sodium selenite) supplementation with dosages of 0.5, 1, 2, and 4 mg Se/kg diet and organic selenium (selenomethionine) with dosages of 1, 2, and 4 mg Se/kg diet. Another treatment was unsupplemented selenium. Juveniles humpback grouper at an initial average length of 6,39±0,41 cm and body weight of 4,49±0,65 g were reared in 90×40×35 cm3 aquaria and fed artificial diet (pellet) two times daily (08.00 and 16.00) at satiation. Fishes were reared for 40 days at a stocking density of 12 fish per aquarium on sea water with salinity of 30–31 ppt and temperature of 28–29 °C. The results of this study showed that the source of selenium supplementation (inorganic or organic) affected growth performance, glutathione peroxidase (GPx) enzyme activity, and blood profiles of the experimental fish. Generally, it was found that selenomethionine supplementation resulted in better fish performance than sodium selenite. In sodium selenite supplementation, survival declined with the increased dosages of Se in the diet, and the supplementation at dosage of 0,5 mg Se/kg diet showed a toxic effects. Histopatological test showed that there were damage in livers, kidneys, and intestines of fish supplemented with sodium selenite from 0.5 to 4 mg Se/kg diet. On the contrary, supplementation of selenomethionine up to 4 mg Se/kg did not show any signs of toxicity and the survival was on 86.11 to 97.22%. Feed efficiency, protein retention, lipid retention, and Se retention indicated that a dosage of 4 mg Se/kg selenomethionine supplementation was the best dosage.</p><p>Keywords: selenium, viability, growth, Cromileptes altivelis, humpback grouper</p>

ABSTRACTThe study proposed to discover the optimum protein content and energy-protein ratio in practical diet for snakehead, Channa striata. The experiment applied complete randomized design, consisted of six treatments with four replications on each treatment. The treatments were: A (32.5%; 11.82 kcal GE/g), B (32.5%; 13.32 kcal GE/g), C (37.17%; 10.64 kcal GE/g), D (37.33%; 12.07 kcal GE/g), E (43.08%; 10.02 kcal GE/g), and F (42.88%; 10.66 kcal GE/g). Snakehead with average weight of 6.21 ± 0.03 g were reared for 8 weeks. The treatments showed significant results. Increased protein dietary level had increased the growth rate and treatment with high energy-protein ratio at the same protein dietary level provided better growth performance. However, increased energy-protein ratio at E and F treatments caused a decline in growth performance. The improvement of energy-protein dietary ratio had positive correlation with the level of lipid and protein content in fish body. Similar finding was found in liver and muscle glycogen. The results also showed that the increament of energy-protein dietary ratio was significantly and positively correlated with cholesterol, triglyceride, HDL, glucose, and albumin, yet it had no significant effect on LDL. It can be concluded that excellent growth performance was achieved by protein dietary level of 37.33% and energy-protein ratio of 12.07 kcal GE/g.Keywords: energy-protein ratio, growth, snakehead ABSTRAKPenelitian ini bertujuan untuk memperoleh kadar protein dan rasio energi-protein pakan buatan yang optimum bagi performa pertumbuhan ikan gabus. Penelitian ini mengaplikasikan rancangan acak lengkap dengan 6 perlakuan, yaitu: A (32,78%;11,82  kkal GE/g), B (32,56%;13,32 kkal GE/g), C (37,17%:10,64 kkal GE/g), D (37,33%:12,07 kkal GE/g), E (43,08%:10,02 kkal GE/g), dan F (42,88%:10,66 kkal GE/g) dan masing-masing terdiri 4 ulangan. Bobot rata-rata ikan gabus yang digunakan dalam penelitian ini yaitu 6,21 ± 0,03 g dan dipelihara selama 8 minggu. Hasil penelitian menunjukkan bahwa peningkatan kadar protein pakan meningkatkan laju pertumbuhan, dan perlakuan dengan rasio energi-protein tinggi pada level protein pakan yang sama memberikan kinerja pertumbuhan yang lebih baik. Namun demikian, pada perlakuan E dan F, peningkatan rasio energi-protein menyebabkan penurunan kinerja pertumbuhan. Peningkatan rasio energi-protein pakan berkorelasi positif terhadap kadar lemak dan protein tubuh ikan. Hal yang sama juga terjadi pada glikogen hati dan otot. Hasil penelitian juga menunjukkan bahwa peningkatan rasio energi-protein pakan berpengaruh nyata (P<0,05) dan  berkorelasi positif terhadap kolesterol, trigliserida, HDL, dan albumin, tetapi tidak berpengaruh nyata terhadap LDL  (P>0.05). Kesimpulan yang didapat adalah kinerja pertumbuhan optimal dihasilkan oleh kadar protein pakan 37,33% dan rasio energi protein pakan 12,07 kkal GE/g.Kata kunci: albumin, energi, ikan gabus, pertumbuhan, protein

Currently, the use of unconventional food sources in the inclusion of fish diets is cause of great interest. The growth performance of African catfish (Clarias gariepinus) was evaluated, with the inclusion of duckweed meal (Lemna perpusilla) in four levels (0, 6, 12 and 18 %) in the diet. African catfish with an average weight of 1.27 ± 0.03 g, were distributed in a completely randomized design, with 16 experimental cages (four replicates/treatment). The fingerlings were fed for 48 days of experimentation. An analysis of variance and a Duncan´s test were performed. No significant differences were found (p< 0.05) for the first two levels evaluated, but with the rest there were differences, as the percentage of inclusion of the duckweed meal in the ration increased. Final weight was decreasing, as well as absolute growth rate, increase in daily weight, feed conversion ratio and food efficiency. Survival throughout the experiment was between 72 y 65 % in all treatments. The inclusion of duckweed meal in the diet did not affect the parameters of water quality. It was concluded that the L. perpusillase meal can be included up to 12 % in diets for African catfish fingerlings, without affecting the growth performance.
