Abstract

Perkembangan ovarium ikan mempengaruhi kualitas anakan yang dihasilkan. Penelitian bertujuan mempercepat kematangan gonad ikan patin dengan suplemetasi ekstrak katuk (0,6 g/kg pakan), tepung kunyit (4,8 g/kg pakan), dan vitamin C (599 mg/kg pakan). Penelitian menggunakan rancangan acak lengkap, 8 perlakuan dan 3 ulangan, yaitu CON (Kontrol), SA (ekstrak katuk), TU (tepung kunyit), VC (vitamin C), SATU (ekstrak katuk dan tepung kunyit), SAVC (ekstrak katuk dan vitamin C), TUVC (tepung kunyit dan vitamin C), dan COM (ekstrak katuk, tepung kunyit, dan vitamin C). Induk ikan dipelihara selama 2 bulan dengan pemberian pakan dosis 5% bobot tubuh. Parameter yang diamati adalah bobot induk, bobot gonad, gonadosomatik indeks (GSI), histologi ovarium, dan diameter oosit fase endogenous vitelogenesis. Hasil penelitian menunjukkan bahwa penambahan ekstrak katuk, tepung kunyit, dan vitamin C menghasilkan nilai GSI dan bobot gonad yang lebih tinggi dibandingkan dengan kontrol. Perkembangan oosit dengan suplementasi ekstrak katuk, tepung kunyit, dan vitamin C mencapai fase endogenous vitelogenesis, sedangkan pada perlakuan kontrol masih banyak oosit pada fase previtelogenesis. Ukuran oosit fase endogenous vitelogenesis tertinggi ditemukan pada perlakuan kombinasi (603.60±99.09 µm) dan terendah pada kontrol (412.60±39.76 µm). Dapat disimpulkan bahwa penambahan ekstrak katuk, tepung kunyit, dan vitamin C mampu mempercepat perkembangan dan kualitas oosit ikan patin.

Abstract

Monopterus albus is a protogynous hermaphrodite species that undergoes a unidirectional sex change from female to male. Asian swamp eel cultivation activities face constraints in seeding due to limited mature gonad broodstock. This study aims to evaluate the effect of administering a combination of PMSG + Antidopamine (OodevⓇ) and hCG on the induction of gonad maturation of Asian swamp eels at various body sizes. The research design used was a factorial design consisting of control treatment (without hormone injection), P1 = hCG (dose 20 IU/kg), P2 = OodevⓇ (dose 0.5 ml/kg), and P3 = hCG+OodevⓇ (dose 20 IU+0.5 ml/kg) with body length groups, namely K1 (15–25 cm), K2 (30–40 cm), and K3 (45–55 cm). The results showed that eels in group K1 had the highest body length growth (3.63 ± 0.96 cm), while the highest body weight gain (5.30 ± 1.30 grams) in K3 (P<0.05). Administration of oodevⓇ showed the highest values ​​for GSI = 8.13 ± 0.72% and HSI = 4.36±0.80% in K1 compared to K2 (GSI = 6.95 ± 2.86%; HSI = 3.26 ± 0.68%) with female sex. In contrast, group K3 experienced a decrease in GSI = 0.81 ± 0.11% and HSI = 2.48 ± 1.06% accompanied by masculinization. Administration of oodevⓇ also increased the concentration of estradiol-17β in K1 and K2, while testosterone increased in K3. The conclusion of this study is that administering oodevⓇ to 15-40 cm sized Asian swamp eels can accelerate gonad maturity with female sex status, while at sizes >45 cm it can accelerate masculinization and maturation of male gonads. Keywords: body length size, gonad maturation, masculinization, Monopterus albus, oodevⓇ ABSTRAK Monopterus albus adalah spesies hermaprodit protogini yang mengalami perubahan jenis kelamin dari betina ke jantan secara searah. Kegiatan budidaya belut sawah menghadapi kendala dalam pembenihan karena keterbatasan induk matang gonad. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian kombinasi PMSG + Antidopamine (OodevⓇ) dan hCG terhadap induksi pematangan gonad belut sawah pada berbagai ukuran tubuh. Desain penelitian yang digunakan adalah rancangan faktorial yang terdiri dari perlakuan kontrol (tanpa injeksi hormon), P1 = hCG (dosis 20 IU/kg), P2 = OodevⓇ (dosis 0,5 ml/kg), dan P3 = hCG+OodevⓇ (dosis 20 IU+0,5 ml/kg) dengan kelompok ukuran panjang tubuh yaitu K1 (15–25 cm), K2 (30–40 cm), dan K3 (45–55 cm). Hasil penelitian menunjukkan bahwa belut kelompok K1 memiliki pertumbuhan panjang tubuh tertinggi (3,63 ± 0,96 cm), sementara pertambahan bobot tubuh tertinggi (5,30±1,30 gram) pada K3 (P<0,05). Pemberian oodevⓇ menunjukkan nilai tertinggi untuk GSI = 8,13±0,72% dan HSI = 4,36±0,80% pada K1 dibandingkan dengan K2 (GSI = 6,95±2,86%; HSI = 3,26±0,68%) dengan jenis kelamin betina. Sebaliknya, kelompok K3 mengalami penurunan nilai GSI = 0,81±0,11% dan HSI = 2,48±1,06% disertai dengan maskulinisasi. Pemberian oodevⓇ juga meningkatkan konsentrasi estradiol-17β pada K1 dan K2, sedangkan testosterone meningkat pada K3. Kesimpulan penelitian ini adalah pemberian oodevⓇ pada belut sawah ukuran 15-40 cm dapat mempercepat kematangan gonad dengan status kelamin betina sedangkan pada ukuran >45 cm dapat mempercepat maskulinisasi dan pematangan gonad jantan. Kata kunci: maskulinisasi, Monopterus albus, oodevⓇ, pematangan gonad, ukuran panjang tubuh

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

Estradiol, vitellogenin levels, and egg diameter are indicators of oocyte quality in aquaculture. This study evaluated the performance of 17β-estradiol (E2) and vitellogenin (Vtg) concentrations in eggs and oocyte diameter during the reproductive period of Oreochromis niloticus at the Fish Breeding Research Center, Sukamandi, Subang, West Java. Sixmonth- old female fish were fed a diet supplemented with varying doses of curcumin analog in the morning and evening for six weeks. The study used a completely randomized design with seven treatments and three replicates. E2 and Vtg concentrations in eggs were analyzed using the enzyme-linked immunosorbent assay (ELISA) Fish kit. The results indicated that the supplementation of curcumin analog in female broodfish of red tilapia increased the concentration of E2, which in turn stimulated Vtg synthesis in the liver, subsequently stored in developing follicles during gonadal maturation. The group supplemented with 2.4 mg of curcumin analog per 100 g of feed exhibited the highest concentrations of E2 (114.46 ng/mL) and egg Vtg (55.63 mg/mL). This study provides valuable insights for enhancing reproductive performance by incorporating curcumin analogs into the feed for commercial tilapia farming.

Abstract

Graphical Abstract Highlight Research Genus Nomorhamphusfrom three river inlets of Lindu Lake, Central Sulawesi was identified as Nomorhamphus with CO1 gene. Green wavelength can accelerate growth and maturation. Wild fish Nomorhamphus can complete life cycles in an aquaculture environment. Domestication level two is completed. Abstract Genus Nomorhamphus is an endemic fish that can be found in Sulawesi, Indonesia. This fish belongs to the halfbeak group and has diverse colors and morphology. It has economic value as an export commodity in the ornamental fish trade. Exploration of the genetic relationship of genus Nomorhamphus in Central Sulawesi is still limited. Nomorhamphus's fulfillment of export demand still comes from wild catches. This study aimed to identify the genetic relationship of genus Nomorhamphus in the inlet rivers of Lake Lindu, Central Sulawesi, and evaluate the adaptation response of genus Nomorhamphus to different wavelengths of light exposure. Caudal fin of six fish from the three inlet rivers of Lake Lindu were preserved in 95% ethanol for DNA extraction purposes. This research used a completely randomized design with three treatment, namely rearing under white (400 nm), green (525 nm), and red (625 nm) light for 60 days. Each treatment had three replications in the form of aquariums, with each aquarium being filled with four fish. A total of 42 fish were utilized in the study. CO1 sequence was amplified with universal primers of FISH-F2 and FISH-R2. The PCR amplification products were then sequenced and performed with phylogenetic tree analysis. The genetic diversity analysis suggests that the genus Nomorhamphus of all three rivers, Lindu Lake, Central Sulawesi is one species as Nomorhamphus sp.. Male and female growth length and gonad maturation were developed faster under green light exposure, while survival rate, blood glucose level, and color quality were not significantly different under different light. Exposure of wild fish to green light Nomorhamphus sp. can accelerate gonad maturation and growth to accelerate domestication.

Abstract

The study investigated the influence of the different LED light spectrums on the maturation of the gonads in female synodontis broodstock and examined the maturation-related gene expression levels. Female synodontis were exposed to four different LED light spectra, specifically: white, blue, green, and red, for a continuous period of 120 days rearing. This study employed a completely randomized design, consisting of four treatments and five individual fish as replication for each treatment. An analysis was conducted on the gonadosomatic index (GSI), hepatosomatic index (HSI), gonad histology, estradiol levels, kiss2 and gnrh2 mRNA expression levels. The utilization of blue LED light treatment is highly effective in enhancing the reproductive parameters in female synodontis fish. The results show that brain and gonad kiss2 mRNA expression levels are not significantly different (P<0.05), while gnrh2 mRNA expression levels were significantly different (P<0.05) and had the highest expression in the gonads. The results suggest that light exposure can induce changes in the expression levels of kiss2 and gnrh2 mRNA, as well as control reproduction.

Abstract

Perilaku kanibal pada benih ikan baung (Hemibagrus nemurus) menjadi permasalahan pada pembenihannya. Salah satu pendekatan yang sudah dilakukan untuk mengendalikan kanibalisme pada ikan adalah pemberian triptofan.  Penelitian ini bertujuan untuk mengetahui pengaruh triptofan terhadap kejadian kanibalisme dan kandungan konsentrasi hormon steroid pada benih ikan baung. Panjang awal benih yang digunakan adalah 4,98±0,1 cm yang dipelihara di dalam akuarium berkapasitas 20 L dengan kepadatan 3 ekor per L.  Selama penelitian, benih ikan baung diberi pakan komersial (40% protein) yang disuplementasi triptofan dengan konsentrasi berbeda, yaitu tanpa suplementasi triptofan (A), suplementasi triptofan 0,25% (B), suplementasi triptofan 0,50% (C), suplementasi triptofan 0,75% (D), dan suplementasi triptofan 1% (E). Setiap perlakuan terdiri dari tiga kali ulangan. Pakan diberikan empat kali sehari secara satiasi. Parameter yang diamati adalah tipe kanibal, indeks kanibal, kematian normal, sintasan, performa pertumbuhan serta konsentrasi hormon (estradiol, testosteron, dan kortisol). Hasil penelitian menunjukkan bahwa pemberian pakan yang diperkaya triptofan memberikan penurunan kejadian kanibal dan peningkatan sintasan benih ikan baung. Pemberian triptofan juga menurunkan kandungan estradiol tubuh, dan penurunan ini ada kaitannya dengan penurunan kejadian kanibalisme. Performa pertumbuhan benih ikan baung meningkat dengan pemberian pakan yang ditambahkan triptofan.  Hasil penelitian ini menunjukkan bahwa suplementasi 0,50–0,75% triptofan pada pakan efektif menurunkan kejadian kanibalisme pada benih ikan baung.The cannibal behavior of Asian redtail catfish (Hemibagrus nemurus) is a problem in the hatchery. One approach that has been used to control cannibalism in fish is the use of tryptophan. This study aimed to determine the effect of tryptophan on the incidence of cannibalism and the content of steroid hormones in Asian redtail catfish juveniles. The study was conducted using the fish with a body length of 4.98±0.14 cm reared in aquariums with a water volume of 20 L with a density of 3 fish per L. Fish were given commercial feed (40% protein) supplemented with tryptophan with different concentrations, namely without tryptophan supplementation (A), tryptophan supplementation 0.25% (B), tryptophan supplementation 0.5% (C), tryptophan supplementation 0.75% (D), and tryptophan supplementation 1% (E). Each treatment consisted of three replications. Feed were given four times a day at satiation level. Parameters observed were cannibal type, cannibal index, normal mortality, survival rate, growth performance, and hormone concentration (estradiol, testosterone, and cortisol). The results showed that giving tryptophan through feed decreased the incidence of cannibalism and increased the survival of Asian redtail catfish juveniles. The addition of tryptophan to the feed decreased the concentration of estradiol in the body of fish and it is associated with a decrease in the incidence of cannibalism, thereby improving survival.  Furthermore, the supplementation of tryptophan also increased growth performance. The results of this study showed that supplementation of 0.50-0.75% tryptophan in feed was effective in reducing the incidence of cannibals in Asian redtail catfish juveniles.

Abstract

Beberapa upaya yang dilakukan untuk menanggulangi adanya kanibalisme pada ikan adalah dengan pemberian hormon sintesis estradiol-17β dan pemberian asam amino triptofan (bahan baku biosintesis serotonin) dalam pakan. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh pemberian tepung kedelai terhadap tingkat kanibalisme benih ikan lele. Tiga dosis perlakuan penambahan tepung kedelai yaitu: 0 (Kontrol), 50 (TK50), dan 100 g kg-1 pakan (TK100). Terdapat dua perlakuan kontrol yaitu penambahan hormon menggunakan 17α-metiltestosteron 30 mg kg-1 pakan (MT) dan estradiol-17β 50 mg kg-1 pakan (E2). Penelitian ini menggunakan benih ikan lele berukuran 2,90 ± 0,41 cm dengan padat tebar 2000 ekor m-2. Pemeliharaan dilakukan selama 30 hari dengan pemberian pakan dilakukan tiga kali sehari (07.00, 12.00, dan 18.00). Metode yang digunakan dalam penelitian ini adalah rancangan acak lengkap dengan menggunakan lima perlakuan yang masing masing diulang sebanyak tiga kali. Hasil dari penelitian ini menunjukkan bahwa penambahan TK100 pada pakan dapat meningkatkan tingkat kelangsungan hidup, menekan adanya kanibalisme serta ikan yang berpotensi kanibal (P<0,05). Hasil dari kinerja pertumbuhan menunjukkan bahwa nilai laju bobot mutlak, laju panjang mutlak, laju panjang spesifik, dan koefisien keragaman panjang memiliki hasil yang berbeda nyata antarperlakuan (P<0,05) dan perlakuan laju bobot spesifik tidak berbeda nyata (P>0,05). Penambahan tepung kedelai dalam pakan mampu menekan adanya kanibalisme pada benih ikan lele sebesar 21,21%. Penurunan kanibalisme tersebut sejalan dengan adanya peningkatan kelangsungan hidup pada benih. Suplementasi tepung kedelai dalam pakan dapat menjadi alternatif solusi untuk penurunan tingkat kanibalisme pada pemeliharaan benih ikan lele.Several attempts have been made to reduce cannibalism in fish by supplementing the synthetic hormone estradiol-17β and amino acid tryptophan (raw material for serotonin biosynthesis) in feed. This study aimed to evaluate the effect of soybean meal on the level of cannibalism of catfish fingerlings. Three treatment doses of the supplementation of soybean meal were 0 (Control), 50 (TK50), and 100 g kg-1 feed (TK100). There were two control treatments, with the addition of hormones using 17α-methyltestosterone 30 mg kg-1 feed (MT) and estradiol-17β 50 mg kg-1 feed (E2). This study used catfish fingerlings measuring 2.90 ± 0.41 cm with a stocking density of 2000 m-2. The experiment was conducted for 30 days, thrice daily feeding (07.00, 12.00, and 18.00). The experiment was arranged in a completely randomized design using five treatments with triplicates. The results show that TK100 produced an increased survival rate and suppressed cannibalism level and potentially cannibalistic fish (P<0.05). The growth performance results show that the total weight rate, relative length rate, specific length rate, and length variation coefficient of catfish fingerlings were significantly different among the treatments (P<0.05). However,  the specific weight rate of catfish fish fingerlings was not significantly different among the treatments (P>0.05). The supplementation of soybean meal in feed suppresses cannibalism in the catfish seeds by 21.21%. The decrease in cannibalism was strongly correlated with the increase in the fingerlings’ survival rate. Supplementing soybean meal in feed can be an alternative solution to reduce cannibalism in catfish seed rearing.

Abstract

Udang galah (Macrobrachium rosenbergii) merupakan komoditas perikanan air tawar yang memiliki ciri dimorfisme seksual pada pertumbuhan individu jantan lebih cepat dibanding betina. Pembentukan populasi monoseks jantan potensial dalam budidaya bertujuan untuk meningkatkan keseragaman, memacu pertumbuhan, dan efisiensi produksi. Induksi sex reversal pada pembentukan individu neomale dapat dilakukan secara hormonal menggunakan bahan yang mengandung derivat testosteron, yaitu serbuk sari pinus (Pinus tabulaeformis). Penelitian ini bertujuan untuk mengevaluasi efektivitas ekstrak serbuk sari pinus terhadap performa sex reversal pada udang galah. Ekstrak serbuk sari pinus dengan dosis berbeda (0,0 mL L-1; 0,2 mL L-1; 0,4 mL L-1; dan 0,6 mL L-1) diberikan melalui perendaman selama 24 jam pada larva udang galah sebelum berdiferensiasi kelamin (PL15) berukuran panjang 12 ± 0,3 mm dan bobot 0,02 ± 0,001 g dengan kepadatan 60 individu per L, kemudian dipelihara selama 45 hari dalam kontainer (60 x 40 x 30 cm3) dengan tinggi air 20 cm dan kepadatan 1 individu per L. Perlakuan dosis ekstrak serbuk sari pinus dosis 0,2 mL L-1 menghasilkan nisbah kelamin jantan 46,69 ± 5,36%, sedangkan peningkatan dosis 0,4-0,6 mL L-1 dan kontrol tidak efektif mengarahkan kelamin jantan (35-42%) dengan tingkat kelangsungan hidup udang PL60 berkisar 66-82%. Ciri kelamin sekunder udang galah jantan PL60 berukuran 30-32 mm berupa male gonopore (MG) dan appendix masculine (AM), sedangkan betina memiliki appendix interna (AI) pada kaki renang kedua dan rongga di antara kedua kaki jalan kelima. Aplikasi ekstrak serbuk sari pinus pada dosis maksimal 0,2 mL L-1 dapat mengarahkan kelamin jantan udang galah.Giant freshwater prawn (Macrobrachium rosenbergii) is a freshwater fishery commodity with sexual dimorphism in which male individuals grow faster than females. The establishment of a male monosexual population is expected to increase individual uniformity, growth rate, and production efficiency. Induction of sex reversal in the formation of the pseudomale can be done hormonally using materials containing testosterone derivatives, for example, pine pollen (Pinus tabulaeformis). This study aimed to evaluate the effectiveness of pine pollen extract on the sex reversal performance of giant prawns. Pine pollen extract with different doses (0.0 mL L-1; 0.2 mL L-1; 0.4 mL L-1; and 0.6 mL L-1) was given by immersion during 24 hours in prawns before sexual differentiation (PL15) with a length of 12 ± 0.3 mm and a weight of 0.02 ± 0.001 g with a density of 60 individuals per L, then reared for 45 days in a container (60 x 40 x 30 cm3) with a water height of 20 cm and a density of 1 individual per L. Treatment with a dose of pine pollen extract at a dose of 0.2 mL L-1 resulted in a male sex ratio of 46.69 ± 5.36%, while increasing doses of 0.4-0.6 ml L-1 and the control were not effective in the sex reversal (35-42%) with a survival rate of PL60 ranged from 66-82%. The secondary sexual characteristics of PL60 male giant prawns measuring 30-32 mm are male gonopore (MG) and masculine appendix (AM), while female giant prawns have an internal appendix (AI) on the second swimming leg and the cavity between the fifth swimming leg. This study concludes that the application of pine pollen extract at a maximum dose of 0.2 mL L-1 could directly induced sex reversal of female to male of giant prawns.
