However, the constraints on larviculture that have been described still arise in the hatchery. This study compares several hatchery parameters in these three grouper species representing three different genera (Epinephelus, Cromileptes, and Plectropomus). The egg incubation and larval rearing were carried out in a concrete tank (3 x 3 x 1.2 m3) filled with 6-7 m3 seawater. Eggs were stocked with a density of 100,000 eggs/tank. The grouper larvae were reared until they became juvenile. The eggs were incubated until they were hatched in the same container and media as larval rearing. Larvae were reared until 60 dah (days after hatching), and data were taken from the rearing for three cycle's larval culture. Management of grouper larval rearing follows the Good Fish Hatchery M...
viable hatch (Kashiwagi et al. 1987). The same trend in survival times (ST), survival activity index (SAI), and survival rate (SR) was also obtained in Japanese whiting (Sillago janopica), where the larger size of eggs produced more viable larvae than smaller eggs (Kashiwagi et al. 1987). SAI is defined as an index for larval fish quality because it is expressed as a function of larval tolerance to starvation and is positively connected with larval survival (Matsuo et al. 2006). The SAI is a widely used metric for assessing the vitality and quality of larvae in marine fish larviculture (Wang et al. 2013). The SAI is linked to nutrition storage (Wang et al. 2013)

Aplikasi hormon pertumbuhan rekombinan (recombinant growth hormone, rGH) melalui pakan telah terbukti menghasilkan peningkatan pertumbuhan. Secara umum, pemberian GH eksogen dapat meningkatkan kapasitas metabolisme ikan gurami, khususnya metabolisme lemak serta optimasi sintesis dan pemanfaatan protein untuk pertumbuhan pada ikan gurami. Penambahan nutrien non-protein sebagai penghasil energi dapat menurunkan penggunaan protein sebagai sumber energi (protein sparring effect) sehingga dapat meningkatkan fungsi protein dalam menunjang pertumbuhan ikan. Penggunaan pakan dengan kadar protein yang rendah dapat mengurangi harga pakan namun dapat menyebabkan pertumbuhan ikan menjadi lambat sehingga waktu produksi menjadi semakin lama. Kombinasi antara aplikasi rGH dan penggunaan pakan berkadar protein yang berbeda yang diberikan pada benih ikan gurami diharapkan mampu meningkatkan protein sparring effect. Tujuan penelitian ini adal...

The experiment was conducted for 80 days in plastic-lined ponds with dimensions of 1 x 1 x 0.6 m. Two biofloc systems with two C/N ratios (10 and 15), using molasses as the carbon source and a control system without molasses were compared. Mixed-sex Nile tilapia with an initial average body weight of 7.00 ± 0.25 g were stocked at a density of 30 fish m −2. After 30 days of culture, redclaw crayfish with initial average body weight of 11.50 ± 0.55 g were added to the culture system at a density of 10 crayfish m −2. There were no significant differences in total animal biomass or total weight gain between treatments (P > 0.05). The total feed and overall feed conversion ratio (FCR) differed significantly (P < 0.05) between the biofloc systems and the control. Total ammonia nitrogen (TAN), nitrite nitrogen (NO 2 −N) and nitrate nitrogen (NO 3 −N) concentrations in biofloc systems with a C/N ratio of 15 were generally lower than those of other treatments. Dissolved oxygen concentrations decreased with the increase in the culture period in (4.13-4.40 mg L −1). Based on the results of this study, it can be concluded that an increase in the C/N ratio has positive effects on the feed utilization efficiency and water quality in biofloc-based tilapia-redclaw crayfish co-culture systems.

The rGH was mixed with chicken egg yolk and sprayed on to artificial feed with different protein levels (34, 28, and 21%; isoenergy). Each treatment group of gourami was paired with a control group that received feed of the same protein level, but without rGH supplementation. Juvenile of giant gourami (weight 15.83 + 0.13 g) were fed diets containing rGH, to apparent satiation, 2 times a week. Fish were reared from less than 2 months old for 42 days in 100 L glass aquaria at an initial density of 10 fish per aquarium. At the end of this period, the biomass and daily growth rate (SGR) of the fish were measured and the feed conversion ratio calculated and compared. Our data showed that fish fed rGH-supplemented diets experienced higher growth than fish in the control groups and showed that fish with higher protein diets experienced higher growth than the groups with less protein diets. The group with the highest biomass gain, SGR, and lowest feed conversion ratio (FCR) was the group fed a 34% protein diet supplemented with rGH. Furthermore, biomass gain, SGR, and FCR in the rGH treatment group with a 28% protein diet matched the measurements of the non-rGH control group receiving a 34% protein diet (P > 0.05). We conclude that giant juvenile gourami given feed supplemented with recombinant growth hormone will experience increased growth and dietary utility compared with gourami given the same feed without supplementation.

The same trend in survival times (ST), survival activity index (SAI), and survival rate (SR) was also obtained in Japanese whiting (Sillago janopica), where the larger size of eggs produced more viable larvae than smaller eggs (Kashiwagi et al. 1987). SAI is defined as an index for larval fish quality because it is expressed as a function of larval tolerance to starvation and is positively connected with larval survival (Matsuo et al. 2006). The SAI is a widely used metric for assessing the vitality and quality of larvae in marine fish larviculture (Wang et al. 2013). The SAI is linked to nutrition storage (Wang et al. 2013)

Aplikasi hormon pertumbuhan rekombinan (recombinant growth hormone, rGH) melalui pakan telah terbukti menghasilkan peningkatan pertumbuhan. Secara umum, pemberian GH eksogen dapat meningkatkan kapasitas metabolisme ikan gurami, khususnya metabolisme lemak serta optimasi sintesis dan pemanfaatan protein untuk pertumbuhan pada ikan gurami. Penambahan nutrien non-protein sebagai penghasil energi dapat menurunkan penggunaan protein sebagai sumber energi (protein sparring effect) sehingga dapat meningkatkan fungsi protein dalam menunjang pertumbuhan ikan. Penggunaan pakan dengan kadar protein yang rendah dapat mengurangi harga pakan namun dapat menyebabkan pertumbuhan ikan menjadi lambat sehingga waktu produksi menjadi semakin lama. Kombinasi antara aplikasi rGH dan penggunaan pakan berkadar protein yang berbeda yang diberikan pada benih ikan gurami diharapkan mampu meningkatkan protein sparring effect. Tujuan penelitian ini adal...

The experiment was conducted for 80 days in plastic-lined ponds with dimensions of 1 x 1 x 0.6 m. Two biofloc systems with two C/N ratios (10 and 15), using molasses as the carbon source and a control system without molasses were compared. Mixed-sex Nile tilapia with an initial average body weight of 7.00 ± 0.25 g were stocked at a density of 30 fish m −2. After 30 days of culture, redclaw crayfish with initial average body weight of 11.50 ± 0.55 g were added to the culture system at a density of 10 crayfish m −2. There were no significant differences in total animal biomass or total weight gain between treatments (P > 0.05). The total feed and overall feed conversion ratio (FCR) differed significantly (P < 0.05) between the biofloc systems and the control. Total ammonia nitrogen (TAN), nitrite nitrogen (NO 2 −N) and nitrate nitrogen (NO 3 −N) concentrations in biofloc systems with a C/N ratio of 15 were generally lower than those of other treatments. Dissolved oxygen concentrations decreased with the increase in the culture period in (4.13-4.40 mg L −1). Based on the results of this study, it can be concluded that an increase in the C/N ratio has positive effects on the feed utilization efficiency and water quality in biofloc-based tilapia-redclaw crayfish co-culture systems.

The rGH was mixed with chicken egg yolk and sprayed on to artificial feed with different protein levels (34, 28, and 21%; isoenergy). Each treatment group of gourami was paired with a control group that received feed of the same protein level, but without rGH supplementation. Juvenile of giant gourami (weight 15.83 + 0.13 g) were fed diets containing rGH, to apparent satiation, 2 times a week. Fish were reared from less than 2 months old for 42 days in 100 L glass aquaria at an initial density of 10 fish per aquarium. At the end of this period, the biomass and daily growth rate (SGR) of the fish were measured and the feed conversion ratio calculated and compared. Our data showed that fish fed rGH-supplemented diets experienced higher growth than fish in the control groups and showed that fish with higher protein diets experienced higher growth than the groups with less protein diets. The group with the highest biomass gain, SGR, and lowest feed conversion ratio (FCR) was the group fed a 34% protein diet supplemented with rGH. Furthermore, biomass gain, SGR, and FCR in the rGH treatment group with a 28% protein diet matched the measurements of the non-rGH control group receiving a 34% protein diet (P > 0.05). We conclude that giant juvenile gourami given feed supplemented with recombinant growth hormone will experience increased growth and dietary utility compared with gourami given the same feed without supplementation.
