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.

Abstract

Triploidization is a polyploidization technique used to produce fish with improved growth, while hybridization is another method to enhance genetic quality through crosses within or between species. This study evaluated the growth performance of allotriploid catfish at the seed stage. The experiment was conducted for 45 days at the Laboratory of Reproduction and Genetics of Aquatic Organisms, Bogor Agricultural University, using a completely randomized design with four treatments and three replications. The treatments consisted of allotriploid, autotriploid, hybrid diploid, and diploid fish. Ploidy analysis showed that allotriploid and autotriploid fish had up to three nucleoli per cell, while hybrid diploid and diploid fish had a maximum of two. Growth results indicated that allotriploid fish achieved the highest final weight (4.68±0.12 g) and length (2.79 ± 0.16 inches), followed by hybrid diploid, autotriploid, and diploid fish. ANOVA results confirmed significant differences in final weight and length among treatments, indicating that ploidy manipulation and hybridization had a substantial impact on growth. However, feed conversion ratio and survival rate did not differ significantly (P > 0.05). Overall, the findings indicate that allotriploid catfish seeds showed superior growth performance compared to autotriploid, hybrid diploid, and diploid fish.

Abstract

One of the problems faced in catfish hatcheries is that the reproductive cycle does not occur throughout the year, so that available male broodstocks with mature gonads are rare. Cryopreservation is a method of storing spermatozoa with the help of diluents and cryoprotectants in frozen conditions to maintain the quality of spermatozoa. Cryopreservation has a negative effect due to the influence of reactive oxygen species (ROS) which causes a decrease in the quality of spermatozoa. An alternative that can be done is using antioxidants in the form of vitamin C and cryoprotectants such as vitamin E. This research aims to test the effectiveness of adding vitamin E and vitamin C to catfish (Clarias gariepinus) sperm on post-cryopreservation sperm quality. The test fish were catfish that had mature gonads and were injected with the ovaprim hormone for final approval. This study consisted of eight treatments and three replications, namely control (fresh sperm), DMSO 10%, DC1 (vitamin C dose 1 mg/mL), DC2 (vitamin C dose 2.5 mg/mL), and DC3 (vitamin C dose 4 mg/mL), DMSO 10%, DE 1 (vitamin E 2 mg/mL), DE2 (vitamin E 4 mg/mL), DE3 (vitamin E 6 mg/mL). The parameters observed include sperm motility, sperm viability, degree of egg fertilization, and degree of egg hatching. Sperm cryopreservation is carried out for one hour. The results showed that the motility, viability, and degree of egg fertilization in the vitamin C and vitamin E treatments were lower (P<0.05) than the control and 10% DMSO as the basic control. Keywords: Clarias gariepinus, cryopreservation, vitamin C, vitamin E   Abstrak Salah satu permasalahan yang dihadapi dalam pembenihan ikan lele adalah siklus reproduksi tidak terjadi sepanjang tahun sehingga ketersediaan induk jantan dengan gonad matang menjadi langka. Kriopreservasi merupakan salah satu metode penyimpanan spermatozoa dengan bantuan bahan pengencer dan krioprotektan dalam kondisi beku untuk mempertahankan kualitas spermatozoa. Kriopreservasi memiliki dampak negatif akibat adanya pengaruh reactive oxygen species (ROS) yang menyebabkan penurunan kualitas spermatozoa. Alternatif yang dapat dilakukan adalah dengan menggunakan antioksidan berupa vitamin C dan krioprotektan seperti vitamin E. Penelitian ini bertujuan untuk menguji efektivitas penambahan vitamin E dan vitamin C pada sperma ikan lele (Clarias gariepinus) terhadap kualitas sperma pascakriopreservasi. Ikan uji adalah ikan lele yang telah memiliki gonad matang dan disuntik hormon ovaprim untuk persetujuan akhir. Penelitian ini terdiri dari delapan perlakuan dan tiga kali ulangan, yaitu kontrol (sperma segar), DMSO 10%, DC1 (dosis vitamin C 1 mg/mL), DC2 (dosis vitamin C 2,5 mg/mL), dan DC3 (dosis vitamin C 4 mg/mL), DMSO 10%, DE 1 (vitamin E 2 mg/mL), DE2 (vitamin E 4 mg/mL), DE3 (vitamin E 6 mg/mL). Parameter yang diamati meliputi motilitas sperma, viabilitas sperma, derajat fertilisasi sel telur dan derajat penetasan sel telur. Kriopreservasi sperma dilakukan selama satu jam. Hasil penelitian menunjukkan bahwa motilitas, viabilitas dan derajat fertilisasi sel telur pada perlakuan vitamin C dan vitamin E lebih rendah (P<0,05) dibandingkan kontrol dan DMSO 10% sebagai kontrol dasar.
