Abstract

Tawes fish has economic value and affordable price. Growth rate and survival rate are important factors in cultivation productivity. The purpose of this study was to test the effectiveness of recombinant growth hormone of kertang grouper (rElGH) on the growth response of tawes fish seeds at different stocking densities. This study used a factorial randomized design with two treatment factors and three replications. The treatments were rElGH (dose 0 mg/kg and 2 mg/kg) and different stocking densities (40 fish/m3, 80 fish/m3 and 160 fish/m3). The tawes fish seeds used weighed 2.33 ± 0.002 cm and were 4-5 cm long. Maintenance is carried out for 60 days used a hapa measuring 1.0 × 1.0 × 1.0 m3 with a water height of ±60 cm.  Fish are fed with at satiation method using commercial feed with a protein content of 31-33%. The administration of rElGH was carried out on the first 7 days of maintenance and continued with the provision of feed without rElGH. The results of the Two-way ANOVA analysis showed that the use of rElGH and stocking density and their interactions had significant differences. The best treatment was the provision of rElGH stocking density 40 (R40) with survival rate 100%, specific growth rate 3.58%/day, absolute weight gain 8.75 g, and feed conversion ratio 1.12. The combination of the use of rElGH and increasing stocking density significantly increased the biomass production of tawes fish.

Abstract

The nilem fish (Osteochilus vittatus) has high economic value, but its growth rate is relatively slow. One potential solution to accelerate its cultivation period is the use of recombinant growth hormone (rGH). This study aimed to evaluate the effect of oral administration of rGH derived from Epinephelus lanceolatus (rElGH) on the growth rate of nilem fish juveniles at different stocking densities. A completely randomized design with three replications was used in this study. Juvenile fish with an average length of 4.43±0.03 cm and weight of 0.96±0.03 g were reared in aquaria measuring 100 × 50 × 50 cm with a water height of 20 cm for 30 days. The fish were fed commercial feed containing 31–33% protein, with rElGH-supplemented feed given to satiation twice daily (at 08:00 and 16:00) during the first seven days, followed by regular feed without rElGH. The best production performance was obtained in the R30 treatment group (30 fish per 100 L with rElGH), with an absolute weight gain (AWG) of 3.4 g, a survival rate of 98.89%, and a specific growth rate (SGR) of 4.8% per day, indicating that nilem fish given rElGH grew faster.

Abstract

Catfish (Clarias sp.) aquaculture in Kediri Regency, East Java, faces challenges due to the limited availability of high-quality broodstock and the lack of mastery in catfish spawning technologies, such as broodstock selection and the use of natural materials and probiotics to accelerate gonad maturation. These issues formed the basis for implementing a community empowerment program titled "Empowering Fish Farmers through Reproductive Process Education to Improve Catfish Seed Productivity in Kediri Regency." The program aimed to educate fish farmers on proper catfish breeding techniques, from broodstock selection to the use of probiotics and pine fruit extract to enhance gonad maturation and broodstock rematuration, through outreach activities. The community service program included public outreach to fish farming communities and discussions on program sustainability with the Kediri Regency Fisheries Department. Key stakeholders involved in the program included IPB University, the Fisheries Department of Kediri Regency, fisheries extension officers (Ministry of Marine Affairs and Fisheries), and catfish farmer groups in the region. The outreach began with a pre-test and concluded with a post-test to evaluate the program’s effectiveness. The materials covered included broodstock selection, application of pine fruit extract and probiotics for accelerating gonad maturation and rematuration. The community responded positively, as evidenced by an increase in average test scores from 78.42 (pre-test) to 92.63 (post-test), indicating that participants had gained a general understanding of catfish farming techniques and, through the outreach, comprehended the technology needed to produce high-quality broodstock.
