Siganid is better known as rabbit fish. In hatcheries, constraint that is still faced is the low survival, which was assumed to occur because of the timing for initial feeding is not solidly known. This research aimed to examine the best initial feeding time for siganus, based on evaluation on eyes and yolk reserves during the transition. The research was conducted from 24-29 March 2021 in IPUW Barru, South Sulawesi. Larvae were obtained from the second progeny (G2) of domesticated Siganus guttatus. Larvae were reared for 5-6 days without feeding. Evaluated parameters include eyes diameter and yolk reserves. Samples were observed with microscope and will be explained descriptively. Water quality parameters were measured, namely DO, salinity, pH and temperature. Eyes diameter at 6 Hour After Hatching (HAH) ranges between 81.5-128.9 m, 13 HAH= 125.5-167.7 m, 24 HAH= 138.2-213.9 m, two days after hatching 2 Day After Hatching (DAH) = 113.6-193.1 m, 3 DAH= 163.1-219.2 m, 4 DAH= 190.4-212.6 m. Yolk reserves diameter ranged between 137-194m (6 HAH), 13 HAH= 152-191m, 24 HAH= 94.0-185m, 2 DAH= 75.3-99.63m, 3 DAH= 42.33-87.58m, 4 DAH= 38.17-55.59m. After age 5 DAH, there are no larvae found alive (dead). Eyes developed at age 6 HAH and experienced pigmentation at age 24 HAH. Conversely, yolk reserves diameters were getting smaller since age 24 HAH and completely disappear at age 4 DAH. It indicates that eyes effectively see feeds at age 2 DAH. Therefore, initial feeding should be started. The water quality parameters measured were still in normal conditions according to the life of S. guttatus larvae. From this research, it can be concluded that eyes have been well functioned at age 2 DAH and yolk reserves was finished at age 4 DAH. Therefore, the initial feeding should be done at the age of 2 DAH.Keywords:Development, Siganus guttatus larvae,Transition

This study aims to evaluate the culture performance of tilapia (Oreochromis niloticus) that have been treated with 17-methyltestosterone (MT) and without MT (w-MT), feed with different protein levels (20, 24, and 28%) and recombinant Epinephelus lanceolatus growth hormone (rElGH)-diet. The research was conducted in 9 treatments and triplicate. Tilapia larvae were soaked twice, totaling 500 larvae, at the age of 10 days after hatching (DAH) and the age of 14 DAH was soaked for 4 hours using 1/l MT 2 mg/l solution. Fish maintenance was conducted in an aquarium of 1.0x0.5x0.5 m3 in the first month, and three months later in net cages (2.0x2.0x1.5 m3). Daily growth rate (DGR) and biomass gain (BG) were increased in line with increasing feed protein content and rElGH supplementation. The highest DGR and BG values were MT+28+rElGH (P 0.05) treatment. The highest feed consumption and the lowest feed conversion ratio were also obtained in the MT+28+rElGH treatment (P 0.05). Fish survival was ranged from 79.89 to 90.28% (P 0.05). The highest profit potential was found in the MT+28+rElGH treatment. The efficient aquaculture can be obtained by feeding sex-reversed tilapia at a protein level of 28% and a diet supplemented with rElGH.Keywords:Feed conversion ratioGrowth hormoneProtein retention17-methyltestosterone

Highlight Research The dose, duration of immersion, and time interval of immersion of the estradiol-17β affect the rate of cannibalism and increase the seed survival of Asian redtail catfish in low treatment in this research. Over optimum treatment increased the incidence of cannibalism at Asian redtail catfish and decrease growth performance. Treatment of estradiol-17β, give the ability of Asian redtail catfish to live on high density The treatment of estradiol-17β, has an effect on concentration plasma of body testosterone and cortisol Abstract The cannibalistic behavior of Asian redtail catfish greatly hampers the supply of these fish seeds, invoking the need to be controlled. Estradiol is one of the hormones that has been known to reduce cannibalistic behavior on fish. This study aimed to evaluate the effect of estradiol-17β immersion on the incidence of cannibalism in the rearing of post larvae of Asian redtail catfish. Post larvae was treated with a combination of doses of estradiol hormone 0, 1, and 2 ppm and immersion time of two and four hours with immersion intervals of three and six days with a completely randomized design. Each treatment had a fish density of 10 fish L-1, with mean size individual length of 6.73 ± 0.73 mm (three days of age after hatched), with four replications. Fish were fed with tubifex up until satiation point and reared for 30 days. The results showed that the administration of the estradiol-17β through immersion with a dose of 1 ppm for two hours and interval of six days was able to reduce the level of cannibalism and increase the survivability. A further increase in dose, immersion time, and interval had the opposite effect. Estradiol-17β immersion with certain dose, duration, and interval affected the rate of cannibalism, growth rate, and survival. Estradiol-17β immersion at a dose of 1 ppm for two hours and six days interval was the best to reduce the level of cannibalism and normal mortality in post larvae of Asian redtail catfish.

One of the obstacles in Asian redtail catfish hatchery is the high cannibalism incidence. Cannibalism is associated with aggressive behavior caused by hormonal metabolism especially of testosterone. The purpose of this study was to evaluate the effect of testosterone administration on the cannibalism incidence in the Asian redtail catfish juveniles. The experiment was conducted by rearing fish with initial length of 4.09±0.19 cm in 16 of 20 L aquariums with a density of 2 fish L-1. The experiment was designed with a completely randomized design with 4 treatments which were different level of 17α-methyltestosterone supplementation in feed, i.e., 0 mg kg-1 feed (A) as control, 7.5 mg kg-1 feed (B), 15 mg kg-1 feed (C), and 30 mg kg-1 feed (D). Each treatment has 4 replications. Fish fed experimental diet (40% protein) 4 times a day to satiation for 30 days. The parameters observed were type and index of cannibalism, aggressive behavior, survival rate, normal mortality, growth performance, hormones concentrations (estradiol, testosterone, and cortisol), and water quality. The results showed that cannibalism type II (the fish eaten completely or missing) and cannibalism index increased with the increasing doses of testosterone administration in the feed with the highest cannibalism incidence was 40.63%. The highest survival rate was found in treatment B (73.75±2.50%) and was not significantly different from the control treatment (69.38±2.39%). No differences in testosterone concentration and in the growth performance among the treatments. However, there was a trend of decrease in the estradiol concentration of Asian redtail catfish juveniles fed ration supplemented with the increasing doses of 17α-methyltestosterone. Based on the results obtained in this research, estradiol changed in the body's plasma, it appears that there was a role for plasma estradiol concentration in controlling cannibalism of Asian redtail catfish juveniles. It concluded that the testosterone administration affected the cannibalism incidence in the Asian redtail Catfish.

This study aims to evaluate the effectiveness of NSP enzyme and organic chromium supplementation in low-protein Colosoma macropomum diet to increase carbohydrate utilization. The diets contains isoprotein (20%) and isoenergy. Factorial design with two factors, namely NSP enzyme (0 and 1 g/kg) and organic chromium (0, 1, and 2 mg/kg). Fish are reared in an aquarium measuring 80 x 50 x 35 cm3 and containing 75 L of water and stock at the density of 15 fish and reared for 60 days. The test parameters used are postprandial blood glucose levels, antioxidant activity, glycogen in muscle and liver, and growth performance. The results showed that the highest postprandial blood glucose levels were when the NSP enzyme was administered. Furthermore, the lowest malondialdehyde (MDA) values and the highest superoxide dismutase (SOD) and glutathione peroxide (GPx) values were obtained in fish fed feed containing 1 g/kg of NSP enzyme and 1 mg/kg organic chromium. Fish fed feed containing 1 g/kg NSP enzyme and 1 mg/kg organic chromium showed significant values in liver and muscle glycogen as well as growth performance compared to other treatments. From this research, it can be concluded that supplementation of NSP enzyme and organic chromium at doses of 1 g and 1 mg per kg of feed produces the best growth performance and anti-oxidant capacity in pomfret fish.

This experiment was conducted to evaluate the quality of rotifer enriched with four kinds of enrichement materials from the stand point of essensial fatty acids. Rotifer was enriched at 24 - 25oC for 18 hours at a density of 1000 ind/ml. Rotifers were treated by four kinds of enrichment materials such as oleic acid (R-OA), two different density of Nannochloropsis oculata, (4x107 and 16x107 cell/ml; R-N18 and R-N42) two different levels of eicosapentaenoic acids (EPA) triglyceride type (EPA-TAG) (20 and 40 ml/ml; R-E20, R-E40) and two different level of EPA ethyl ester (EPA-EE) (R-EE25 and R-EE50%) respectively. Rotifers enriched with Nannochloropsis oculata and EPA-EE type have a similar profile of essensial fatty acid especially on n3-HUFA that dominated by EPA, while DHA was in a trace amount or not detected. In addition Nannochloropsis oculata as an enrichment material showed the highest population density of rotifers during enrichment periods. Rotifer enriched with EPA-TAG has a more complete of essential fatty acid profile compared to other enrichment materials due to their contained both of EPA and DHA. We conclude that rotifer enriched with EPA-TAG as enrichment material showed the best nutritional quality of rotifers from the stand point of essential fatty acid. Key words : Rotifers, enrichment, eicosapentaenoic acid, docosaheksaenoic acid, n3-HUFA ABSTRAK Penelitian ini dilakukan untuk mengetahui profil asam lemak rotifera yang diperkaya dengan berbagai macam jenis dan dosis pengkaya.

This experiment was conducted to improve the protein retention through carbohydrate efficiency in the chromium diet of common carp Cyprinus carpio. Four experimental diets with isonitrogen and isocaloric but different Cr+3 level 0,00; 1,33; 2,23 and 3,96 ppm were used in this experiment. Fish with body weight of 5,31 ± 0,02 gram were reared in aquaria (50 x 40 x 35 cm); 20 fish per aquarium. Fish fed upon the experimental diets three times daily, at satiation for 50 days. Results of this experiment showed that the protein retention could be improved by given Cr+3 in the diet. Based on the respon curve of protein retention (Yi = -1.1678X2 + 3,7223X + 24,818 ; R2 = 0,9) it was found that the optimum Cr*J in the diet was 1,59 ppm. The maximum relative growth rate was found at 2,16 ppm Cr3+ (Y2 = -14,592 X: + 63,18IX + 426,43 ; R = 0,9). The feed efficiency and the survival rate of the fish are the same between treatment (p>0.05). The protein level of the fish from treatment 3,96 ppm Cr+3 was lower than the others; the lipid level of Cr+3 diets was higher than that of non Cr+3 diet; however the carbohydrate level of fish from diet 2,23 Cr+3 was lower than the others. It was concluded that the optimum level of Cr +3 in the diet of common carp was 1,59-2,16 ppm Key words : dietary chromium, common carp, Cyprinus carpio ABSTRAK Penelitian ini bertujuan untuk meningkatkan retensi protein dan pertumbuhan ikan mas Cyprinus carpio melalui peningkatan efisiensi karbohidrat pakan yang diberi kromium (Cr"3). Empat macam pakan dengan kadar Cr+3 yang berbeda yaitu 0,00; 1,33; 2,23 dan 3,96 ppm tetapi kadar protein dan energi yang sama digunakan pada penelitian ini. Ikan mas berbobot 5,31 ± 0,02 gram per ekor dipelihara dalam akuarium (50x40x35 cm) dengan kepadatan 20 ekor. Ikan diberi pakan tiga kali sehari secara at satiation. Pemberian pakan dilakukan selama 50 hari. Hasil penelitian memperlihatkan bahwa adanya pemberian Cr+3 dalam pakan akan mengefisienkan penggunaan karbohidrat pakan sehingga retensi protein akan meningkat pula. Retensi protein tertinggi dicapai pada kadar Cr+3 1,59 ppm (dihitung dari persamaan y, = -1,1678X2 + 3,7223X + 24,818; R2 = 0,9). Pertumbuhan relatif tertinggi dicapai pada kadar Cr+3 2,16 ppm (dihitung dari y2 = -14,592 X2 + 63.181X + 426,43; R2 = 0,9); sedangkan efiseinsi pakan dan tingkat kelangsungan hidup antar perlakuan sama (p>0,05). Kadar protein tubuh perlakuan 3,96 ppm Cr+3 relatif lebih rendah dari perlakuan lainnya. Kadar lemak tubuh ikan yang diberi Cr+3 lebih tinggi dari yang tidak diberi Cr+3; sedangkan kadar karbohidrat tubuh terendah pada perlakuan 2,23 ppm Cr+3. Secara keseluruhan dapat disimpulkan bahwa kadar Cr+3 optimum dalam pakan ikan adalah 1,59-2,16 ppm. Kata kunci : Kromium pakan. ikan mas, Cyprinus carpio
