Ikan baung merupakan salah satu komoditas populer di Indonesia. Dalam pengembangan budidayanya masih diperlukan input teknologi terutama pada proses pembenihan. Penelitian ini bertujuan untuk mengevaluasi karakter biologi reproduksi dan keberhasilannya dalam proses pemijahan pada ikan baung populasi Cirata yang diinkubasi pada suhu 23°C-24°C, 25°C-26°C, 27°C-28°C, dan 29°C-30°C. Inkubasi induk dilakukan pada styrofoam berukuran 45 cm x 35 cm x 25 cm dengan ketebalan 3 cm. Setiap styrofoam diisi satu ekor induk yang matang gonad. Seleksi tingkat kematangan gonad dilakukan secara kanulasi dan induksi hormon menggunakan LHRH analog (0,6 mL/kg). Penyuntikan dilakukan dua kali dengan selang waktu enam jam. Styrofoam diisi air dengan ketinggian 20 cm, dilengkapi tutup pada bagian atas, water heater, dan sistem aerasi. Inkubasi suhu dilakukan secara eksperimental menggunakan rancangan acak lengkap dengan empat perlakuan suhu dan masing-masing perlakuan diulang sebanyak tiga kali. Hasil penelitian menunjukkan suhu optimal inkubasi pada induk yaitu 27°C-28°C dengan waktu laten 8 jam 35 menit, dan derajat ovulasi 100%. Secara statistik inkubasi induk pada suhu 27°C-28°C menunjukkan nilai karakter biologi reproduksi yang berbeda nyata (P<0,05) dibandingkan dengan inkubasi suhu 23°C-24°C dan 25°C-26°C. Nilai biologi reproduksi yang dihasilkan pada perlakuan terbaik tersebut adalah indeks kematangan gonad 8,6 ± 0,5%; fekunditas 23.909 ± 1.473 butir per ekor; derajat pembuahan 85,5 ± 5,5%; derajat penetasan 69,9 ± 5,0%; dan sintasan 72,3 ± 5,8%. Pada inkubasi suhu 27C°-28°C, telur terdistribusi dengan diameter telur rata-rata sebesar 1,5 mm.Asian redtail catfish is one of the most popular fish commodities in Indonesia. However, improvements in its aquaculture technology are still needed, especially in the breeding process. This study was aimed to evaluate the characters of reproductive biology and level of spawning on Asian redtail catfish from Cirata population incubated at different temperature settings of 23°C-24°C, 25°C-26°C, 27°C-28°C, and 29°C-30°C. Broodstock incubation was conducted in styrofoam boxes (sized 45 cm x 35 cm x 25 cm) with a wall thickness of 3 cm. One mature broodstock was placed inside each Styrofoam. Each styrofoam box was previously filled with freshwater of 20 cm deep, equipped with a lid on top, a water heater, and an aeration system. The gonad maturity stage of each broodstock was determined using cannulation, whilst the hormone induction used LHRH hormone analog (0.6 mL/kg). The injection was performed twice within six hours interval. The incubation was arranged in a completely randomized design (CRD) with four temperature treatments with three replicates. The results showed that the optimal incubation temperature for the broodstock was 27°C-28°C with the latent time ovulation of 8 hours 35 minutes and an ovulation rate of 100%. Statistically, the incubation of broodstock at 27°C-28°C showed a significant difference on the reproductive biological character value (P<0.05) compared to temperature ranges at 23°C-24°C and 25°C-26°C. The reproductive biology parameters generated were gonadosomatic index of 8.6 ± 0.5%; fecundity of 23,909 ± 1,473 egg per individual; fertilization rate of 85.5 ± 5.5%; hatching rate of 69.9 ± 5.0%; and survival rate of 72.3 ± 5.8%. At the incubation temperature of 27°C-28°C, the egg was distributed with an average egg diameter of 1.5 mm.

Black ghost knifefish, Apteronotus albifrons, is a South America-introduced ornamental fish species that has been widely cultivated in Indonesia. Some farmers breed this fish with different sex ratios, but the optimum sex ratio remains unclear. This study aimed to evaluate the spawning behavior and reproductive performance of black ghost knifefish with different sex ratios. The treatments in this study were arranged in a completely randomized design consisting of different sex ratios between males and females, namely: A (one male : three females), B (two males : three females), and C (three males : three females). Each treatment was done in triplicate. The broodstock were maintained in an aquarium (80 cm x 40 cm x 40 cm) and fed with bloodworm twice a day. The water was changed every day as much as 60% of the total volume. During the experiment, the parameters of spawning behavior, number of fish spawning, number of eggs, fertilization rate, hatching rate, and daily spawning frequencies were observed. The observation was done for seven days. The study results showed that black ghost knifefish spawned at night (11 pm - 2 am). The mating and spawning occurred between one male and one female. Competition between males was observed in the treatments indicated by aggressive movements of a male toward the others, such as sudden approaching, chasing, and driving away the others. Fish in treatment-B spawned consistently from day-1 to day-5. Fish in treatment-A spawned from day-2 to day-4, while fish in treatment-C spawned only on day-7. The reproductive performance parameters showed no significant difference in all treatments except the hatching rate parameter of treatment-B. The study concludes that better reproductive performance of black ghost knifefish, A. albifrons can be achieved with a spawning ratio of two males and three females. Further research on individual and mass spawning methods with the best spawning ratio of the fish is required.

An experiment was designed to study the effects of curcumin and thyroxine hormone supplementation in the diet to improve the reproductive performance of catfish broodstock by improving egg quality that eventually increases the production of seedlings. Catfish used in this experiment were supplemented with curcumin and thyroxine hormone through their feeds for 12 weeks. The results showed that there was no significant difference (p > 0.05) in the hepatosomatic index (HSI), gonadosomatic index (GSI), percentage of gonad maturity, total cholesterol concentration in the spawned eggs, high density lipoprotein (HDL) concentration in the spawned eggs, fertilization rate of spawned eggs, and hatching rate of fertilized eggs.  However, there were significant differences (p < 0.05) in the concentration of vitellogenin in the spawned eggs, egg diameter of the spawned eggs, and the triglycerides contents of spawned eggs. It was concluded that curcumin and thyroxine supplementations of African catfish increased vitellogenin concentrations and diameters of spawned eggs that have great potential to improve the reproductive performance.

Labeo bata is one of the important minor carps in Bangladesh with great demand as good table fish. The study was conducted to observe the breeding performance at different management practices in Mafatema, Rupali, Modhumoti and Anan fish hatchery and disinfection treatments of water, eggs and fry in Jessore, Bangladesh during 10 March 2014 to 15 May 2015. An improvement in broodstock nutrition and feeding has been shown to greatly improve seed production. Protein and lipid percentage of broodstock diet have been identified as major dietary factors. Protein level was 24.77%, 23.47%, 18.08%, 17.78% and lipid level was 11.07%, 9.50%, 7.74%, 8.14% in Mafatema, Rupali, Modhumoti and Anan fish hatchery respectively. Three concentrations of four chemical-formalin (10, 20, 30 mg/L), malachite green (1, 3, 5 mg/L), NaCl (1, 2, 3 g/L) and methylene blue ( 1, 3, 5 mg/L) treatment regimes and a control were compared for efficacy in treating L. bata eggs to prevent fungus and bacterial infection and improve hatch and survival rate of fry. Highest correlation value between absolute fecundity and body weight (r=.938, p<.05) and total length (r=.891, p<.05) and gonadosomatic index (26.2%) were found in Mafatema fish hatchery among four experimental hatcheries at 24.77% protein and 11.07% lipid level. Better fertilization rate (84.2±5.17%) and hatching rate (82.0±4.30%) were found in Mafatema and Rupali fish hatchery respectively that has significant difference (P<0.05) from that of Modhumoti and Anan fish hatchery at higher protein and lipid level. Lowest deformity rate (6.05+2.65) was observed in Mafatema fish hatchery that was significantly different (P<0.05) from that of Modhumoti fish hatchery. In case of disinfection treatment, methylene blue at 1mg/L bath treatment daily for 4 days showed significantly higher hatching rate (92.33±3.51%) and survival rate (94.33±4.73%).Asian J. Med. Biol.

Udang windu transgenik merupakan udang hasil rekayasa dengan mengintroduksikan gen antivirus yang diisolasi dari udang windu untuk menghasilkan fenotipe yang lebih baik. Domestikasi udang transgenik telah dilakukan dan berhasil memijah/bertelur, tetapi umumnya telurnya infertil yang disebabkan tidak terjadinya pembuahan di tambak pemeliharaan. Udang betina tidak kawin ditandai tidak membawa spermatofor di telikumnya. Upaya untuk mendapatkan telur fertil udang dengan inseminasi buatan (IB) perlu dilakukan. Tujuan penelitian untuk mengevaluasi performa reproduksi udang betina transgenik dan mutu larva yang dihasilkan pasca IB menggunakan sumber spermatofor yang berbeda. Penelitian ini dirancang dengan tiga perlakuan yaitu: IB menggunakan spermatofor udang windu jantan transgenik (SJT), spermatofor udang windu jantan alam Sulawesi Selatan (SulSel) (SJS) dan spermatofor udang windu jantan alam Aceh (SJA). IB dilakukan pada udang windu betina transgenik setelah dua hari moulting. Hasil penelitian menunjukkan bahwa udang windu betina transgenik pasca IB perlakuan SJT menghasilkan total telur fertil sebanyak 766.949 butir, perlakuan SJS 535.644 butir dan perlakuan SJA 678.016 butir dengan daya tetas telur fertil yaitu: pada SJT, SJS, dan SJA masing-masing adalah 53,5%; 53,7%; dan 55,0%. Uji vitalitas larva dengan perendaman dalam larutan formalin 150-200 mg/L, perendaman air tawar: 5-15 menit, dan pengeringan 3-9 menit menghasilkan sintasan larva udang yang relatif sama pada ketiga perlakuan. Nilai morfologi larva perlakuan SJT, SJA, dan SJS adalah masing-masing 85,0; 84,5; dan 75,0. Dari hasil penelitian ini mengindikasikan bahwa performa reproduksi udang windu betina transgenik dan mutu larva yang dihasilkan pasca IB tidak dipengaruhi oleh sumber spermatofor induk udang windu jantan Penaeus monodon.Transgenic tiger shrimp, Penaeus monodon has been developed in the last decade to equip shrimp with immunity against viral diseases. However, the effort to produce large quantities of specific pathogen resistance (SPR) tiger shrimp seed is hampered by several constraints in the domestication process. The successfulness of domesticated broodstock in producing larvae is very low due to low fertilization rate. An artificial insemination (AI) offers a solution to increase fertilization rate in crustacean. This study was aimed to evaluate the reproductive performance of female transgenic tiger shrimp broodstock and their larval quality after artificially inseminated with males from different sources. The spermatophores of male from different sources i.e. transgenic male spermatophore (SJT), wild male from South Sulawesi (SJS), and wild male from Aceh (SJA) were collected through electric shock and inseminated to female transgenic broodstock two days after moulting. The results showed that the total numbers of fertile eggs produced from SJT, SJS, and SJA treatment were 766,949 pcs; 535,644 pcs; and 678,016 pcs, respectively and not significantly different (P>0.05). Similar to the number of fertile eggs, the hatching rate of eggs of SJT (53.5%), SJS (53.7%), and SJA (55.0%) also did not indicate any significant differences (P>0.05). On the larval vitality test by soaking the larvae in formalin and freshwater as well as by air exposure at different duration showed no significant difference on the survival rate (P>0.05) as indicated by score value at each treatment of 85.0, 84.5, and 75.0 for SJT, SJS, and SJA, respectively. In conclusion, the reproductive performance of female transgenic tiger shrimp and their larval quality were not affected by the different sources of spermatophores inseminated artificially during the spawning cycle.

The Relationship

The experiments investigated the reproductive performance of the domesticated broodstock of the silver perch and the relationship between various degrees of oil globule fragmentation and egg quality. Six years old of second generation broodstock (n=3) were evaluated based on the fecundity, fertilisation rate, hatching rate, the degree of oil fragmentation of egg, and the quality of embryos and larvae produced. The fragmentation were grouped into three categories: un-fragmented (cat-1), moderately fragmented (cat-2), and highly fragmented (cat-3). The results showed that the broodstock had a relatively high fecundity (132,400 ± 7,22), fertilization rate (94.27 ± 1.28%), and hatching rates (87.94 ± 1.23%). The survival rate of larvae at 12 days post hatching (dph) in cat-1 (71.3 ± 0.9%) was higher than cat-2 (66.7 ± 0.9%) whereas cat-2 was higher than cat-3 (61.3 ± 0.3%). The eggs was dominated by cat-1 (78.11 ± 2.44%) which was significantly higher than cat-2 (21.26 ± 2.45%) and cat-3 ones (0.40 ± 0.21%). The survival rate of embryo at 20 hours post spawning (hps) and hatching rate of cat-1 (95.33 ± 0.00% and 93.33 ± 0.00%) and cat-2 (90.00 ± 0.00% and 85.00 ± 0.00%) were significantly higher than cat-3 (72.33 ± 1.76% and 60.33 ± 0.00%). The total length (TL) of the larvae of cat-1 and cat-2 (8.44 ± 0.21 mm and 8.35 ± 0.23 mm respectively) were significantly higher than larvae of cat-3 (7.09 ± 0.14 mm). No significant difference was found in the larval deformities among any categories. In conclusion, the reproductive performance of six year-old broodstock silver perch showing acceptable performance and egg categorisation based on oil globule fragmentation can be used as a useful tool to indicate eggs quality of silver perch.
