The purpose of this study was to examine the effect of dietary supplementation with recombinant growth hormone (rGH) on the growth and dietary utility of juvenile giant gourami. 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.

High production costs in grouper nursery can be caused by the use of large fingerlings size and long rearing times. The purposes of this study were to evaluate the culture performance and economic profitability of “cantang” hybrid grouper juveniles reared at different initial stocking sizes and nursery periods. This research lasted from September to December 2017 in one of small scale hatcheries in Buleleng, Bali, Indonesia. This study consisted of two experimental treatments; the first treatment was different initial stocking sizes (body weight and total length) of 0.50 ± 0.07 g and 3.0 ± 2.1 cm; 3.50 ± 0.67 g and 5.0 ± 1.9 cm; and 6.10 ± 0.91 g and 7.0 ± 2.3 cm. The second treatment was different nursery periods with the following arrangement: 15, 30, and 45 days (initial body weight and length of 0.54 ± 0.067 g and 3.0 ± 0.09 cm, respectively). The stocking density in all treatments was 1,000 fish reared in a 2 m x 2 m x 1 m concrete tank. The observed culture performance parameters consisted of survival rate (SR, %), daily growth rate (DGR, g/day), and feed conversion ratio (FCR). The calculated economic profitability parameters were net profit, return-on-investment (ROI, %), and return cost ratio (R/C). The highest culture performance was achieved by the juveniles reared using the largest initial stocking size and longest nursery period. This was in contrast with the economic profitability, in which smaller initial stocking size and middle nursery period had resulted in the highest profit. Based on the culture performance and profitability considerations, the suggested combination of initial stocking size and nursery period for cantang fingerlings is 3.0 ± 2.1 cm initial stocking size and 30 days rearing times.

Three species of groupers, including tiger grouper (Epinephelus fuscoguttatus), humpback grouper (Cromileptes altivelis), and leopard coral grouper (Plectropomus leopardus), have been successfully cultivated. 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 Method (Cara Pembenihan Ikan yang Baik/CPIB) based on Indonesian National Standard (Standar Nasional Indonesia/SNI). The experimental parameters were egg diameter, hatching rate, larvae mouth opening width, survival activity index (SAI), larvae development, and total body length growth. The several hatchery parameters in three grouper fish species are significantly different. The tiger grouper has the best larval performance.
