ABSTRACT This study was aimed to evaluate the growth performance and gonadal development of diploid and triploid striped catfish Pangasianodon hypophthalmus. Triploids were produced through a heat shock method at 42 °C for two minutes, at two minutes after fertilization. Before treatment performed, group of triploid and diploid were separated through nucleolus counting confirmed cromoseme counting. Five individual of each group at the age of nine months were tagged and reared for two months. Parameter of growth performance, feed conversion ratio, and survival rate were analysed using independent-samples t-test at confidence interval 95%, while gonadosomatic index (GSI) and gonad histology were analysed descriptively. No significant differences were observed between diploid and triploid fish in terms of growth performance, feed conversion ratio, and survival rate (P>0.05) during the two months rearing period, while GSI was higher in diploid (P<0.05) compared to triploid females. Histological observations of triploid female gonads showed early development stage, indicating sterility through symptoms such as oocytes degradation and abnormal development. Meanwhile, male gonad developed faster compared to female as spermatids were found in several lobules. As conclusion, diploid and triploid striped catfish P. hypophthalmus growth performance did not differ up to the age of 11 months, although some sterility symptoms were observed in both male and female. Keywords: diploid, triploid, growth, gonad, Pangasianodon hypophthalmus ABSTRAK Penelitian ini bertujuan untuk mengevaluasi performa pertumbuhan dan perkembangan gonad ikan patin siam Pangasianodon hypophthalmus diploid dan triploid. Triploid diproduksi dengan kejut suhu panas pada suhu 42 °C selama dua menit, pada dua menit setelah fertilisasi. Sebelum pengujian, kelompok diploid dan triploid dipisahkan dengan menganalisis jumlah nukleolus yang dikonfirmasi dengan penghitungan jumlah kromosom. Masing-masing lima ekor ikan diploid dan triploid pada umur sembilan bulan ditandai dan dipelihara selama dua bulan. Parameter pertumbuhan, rasio konversi pakan, dan kelangsungan hidup dianalisis menggunakan independent-samples t-test pada selang kepercayaan 95% sedangkan gonadosomatik indeks (GSI) dan histologi gonad dianalisis secara deskriptif. Pertumbuhan, rasio konversi pakan, dan kelangsungan hidup antara diploid dan triploid selama dua bulan pemeliharaan tidak menunjukkan perbedaan yang nyata (P>0,05). Nilai GSI diploid lebih tinggi (P<0,05) dibandingkan triploid, baik pada jantan maupun betina. Hasil histologi menunjukkan bahwa gonad ikan patin betina masih pada tahap perkembangan awal. Namun, indikasi steril terlihat dengan adanya degradasi oosit dan perkembangannya yang terganggu. Gonad jantan berkembang lebih cepat dibandingkan betina, dengan ditemukannya spermatid pada beberapa lobule. Gonad jantan triploid menunjukkan adanya gejala sterilitas tetapi tidak permanen, sebagian masih mampu berkembang hingga fase spermatid, namun jumlahnya lebih sedikit dibandingkan diploid. Berdasarkan penelitian, disimpulkan bahwa pertumbuhan antara ikan patin siam diploid dan triploid hingga umur 11 bulan tidak menunjukkan perbedaan, akan tetapi gejala sterilitas ditemukan baik pada jantan maupun betina triploid.

ABSTRACT Immersion of undifferentiated larval tilapia in high temperature and 17α-methyltestosterone (MT) cab increase the male ratio. However, the effectiveness of immersion in high temperature of water containing MT remains to be evaluated. The purposes of this study were: 1) evaluate the male ratio, growth, and survival of tilapia, and 2) analyze the aromatase brain-type gene expression level in tilapia after immersing in high temperature (36 °C) containing MT at 2 mg/L for four hour with single and double immersion. Aromatase gene expression was analyzed by semi-quantitative RT-PCR (sqRT-PCR) method. The result showed that higher monosex male ratio was obtained by single immersion of MT at 36 °C at room temperature. Gene expression level of aromatase brain-type was lower on single immersion and increased significantly at second immersion compared to control (immersion at room temperature without MT). Immersion using MT and high temperature had no significant effect on fish survival. However the specific growth rate and fish biomass were higher than control. Thus, monosex male tilapia can be produced by single immersion of undifferentiated larvae at 36 °C temperature containing MT. Keywords: male ratio, aromatase, Oreochromis niloticus, temperature, 17α-methyltestosterone ABSTRAK Perendaman larva ikan nila yang belum terdeferensiasi kelaminnya dengan suhu tinggi dan hormon 17α-metiltestosteron (MT) dapat meningkatkan nisbah kelamin jantan. Tetapi, efektivitas perendaman menggunakan MT pada suhu tinggi belum diteliti. Tujuan dari penelitian ini adalah 1) mengevaluasi nisbah kelamin jantan, pertumbuhan, dan kelangsungan hidup ikan nila, dan 2) menganalisis ekspresi gen aromatase tipe-otak pada ikan direndam menggunakan MT dengan dosis 2 mg/L selama empat jam sebanyak satu dan dua kali perendaman pada suhu 36 °C. Ekspresi gen aromatase dianalisis menggunakan metode RT-PCR semi-kuantitatif (sqRT-PCR). Hasil penelitian menunjukkan bahwa kombinasi perendaman MT satu kali pada suhu 36 °C lebih tinggi menghasilkan ikan nila jantan monoseks dibandingkan perendaman MT satu kali pada suhu ruang. Tingkat ekspresi gen aromatase tipe otak pada perendaman satu kali lebih rendah, dan meningkat secara signifikan pada perendaman kedua dibandingkan dengan kontrol (perendaman pada suhu ruang tanpa MT). Perendaman larva menggunakan MT dan suhu 36 °C tidak berpengaruh nyata terhadap kelangsungan hidup, tetapi laju pertumbuhan spesifik dan biomassa ikan perlakuan tersebut lebih tinggi daripada kontrol. Dengan demikian, ikan nila jantan monoseks dapat diproduksi dengan perendaman satu kali pada larva yang belum terdeferensiasi jenis kelaminnya menggunakan MT pada suhu 36 °C.

Nomorhamphus sp. is a freshwater fish that has been traded as an ornamental fish. This fish is unique as an endemic species with a halfbeak-like jaw and orange color on the caudal fin. However, this fish culture information needs a further information. Based on this condition, it is necessary to conduct a study as a basis for ornamental fish breeding and growing-out activities through domestication. A crucial problem in this fish is larval rearing, which can be observed through ontogeny studies. The study was conducted on the newly-born larval behavior, morphological development, andropodium development, growth, and survival rate at the early stages, namely larvae to juvenile. The results showed that the newly-born larvae of Nomorhamphus sp. Lindu had a total length of 1.6-1.8 cm. Larvae could swim four hours 22 minutes after birth and feed artemia nauplii with surface feeding type. The initial juvenile stage occurred 25 days of post-birth period with a total length of 2.0-2.2 cm. The water condition of the rearing during the study could support the larval transformation to juvenile. This study is the first report related to the aquaculture success of the early life stage of Nomorhamphus sp. Lindu at the domestication stage. Keywords: andropodium, domestication, endemic halfbeak, larva development, surface feeding ABSTRAK Nomorhamphus sp. adalah ikan air tawar yang telah diperdagangkan sebagai ikan hias. Ikan ini memiliki keunikan pada statusnya sebagai spesies endemik, bentuk mulut menyerupai paruh setengah (halfbeak), dan warna oranye pada sirip ekor. Namun informasi budidayanya belum diketahui dengan baik. Karena itu perlu dilakukan kajian sebagai dasar dalam kegiatan pengembangbiakan dan pembesaran sebagai ikan hias melalui domestikasi. Salah satu kegiatan penting dalam budidaya yaitu pemeliharaan larva yang dapat diamati melalui studi ontogeni. Kajian pada studi awal ini dilakukan pada stadia awal hidup yaitu larva sampai juvenil. Pengamatan dilakukan pada tingkah laku larva pascalahir, perkembangan morfologi, perkembangan andropodium, pertumbuhan dan sintasan pada lingkungan budidaya. Hasil penelitian menunjukkan bahwa larva Nomorhamphus sp. Lindu yang baru dilahirkan memiliki panjang total 1,6-1,8 cm. Larva telah dapat berenang pada umur empat jam 22 menit pascalahir (pcl) dan bisa makan naupli artemia dengan tipe surface feeding. Stadia awal juvenil terlihat pada umur 25 hari pcl dengan ukuran panjang total 2,0-2,2 cm. Kondisi media pemeliharaan selama penelitian dapat mendukung kehidupan larva sampai juvenil. Penelitian ini merupakan catatan pertama terkait keberhasilan budidaya stadia awal hidup Nomorhamphus sp. Lindu pada tahap domestikasi.

The Channa limbata fish is a type of tropical freshwater fish of the Channidae family which is relatively small as an aquarium ornamental fish with a distinctive color at the tip of its dorsal fin and has a snake-like head (dwarf snakehead). Natural snakehead fishing activities have threatened its sustainability. Breeding C. limbata fish through cultivation can increase its potential for sustainable use. This study aims to evaluate the acclimation response of wild-type dwarf snakehead fish in captivity and its sexual characteristics as a basis for domestication and hatchery technology. The fish samples used were natural catches from rivers in West Java measuring <100 mm to >150 mm of body length then individually acclimated indoors in an aquarium (35×20×20 cm) for 14 days. Snakehead fish live in shallow, slow-flowing river waters with a temperature of 20.2-21.3°C, TDS 16-24 mg/L at neutral pH, while the rearing water temperature and TDS are higher (temperature: 24.9-27.6°C; TDS: 88-110 mg/L). The fish mortality rate during acclimation reached 25% in fish measuring >150 mm of length on tenth day, while fish measuring <150 mm more adaptive with 100% survival. The male fish measuring 100-150 mm have 13-15 pectoral fin rays while female fish have fewer (13-14). The gonad development level of male C. limbata in nature is slower than female fish measuring 100-150 mm with a gonadosomatic index of ovaries reached 10 times higher than testicular. Keywords: acclimation, C. limbata, gonadosomatic index, ovaries ABSTRAK Ikan Channa limbata merupakan jenis ikan air tawar tropis dari famili Channidae yang berukuran relatif kecil sebagai ikan hias akuarium dengan warna yang khas pada ujung sirip punggungnya dan bentuk kepala mirip ular (dwarf snakehead). Aktivitas penangkapan ikan gabus alam telah mengancam kelestariannya. Pembibitan ikan C.limbata melalui budidaya dapat meningkatkan potensi pemanfaatannya secara berkelanjutan. Penelitian ini bertujuan untuk mengevaluasi respons aklimatisasi ikan gabus alam di dalam penangkaran dan karakterisasi seksualnya sebagai landasan teknologi pembenihan ikan gabus C. limbata yang tepat. Sampel ikan yang digunakan merupakan hasil tangkapan alam dari sungai di Jawa Barat berukuran <100 mm hingga >150 mm kemudian diaklimasi indoor di akuarium (35×20×20 cm) selama 14 hari. Ikan gabus hidup di perairan sungai yang dangkal berarus lambat dengan suhu 20,2-21,3°C, TDS 16-24 mg/L dan pH netral, sedangkan suhu air pemeliharaan dan TDS lebih tinggi (suhu: 24,9-27,6°C; TDS: 88-110 mg/L). Angka kematian ikan selama aklimatisasi mencapai 25% pada ikan berukuran >150 mm hari ke 10, sedangkan ikan berukuran <150 mm lebih adaptif dengan sintasan 100%. Ikan jantan C.limbata berukuran 100-150 mm memiliki jari-jari sirip pektoral berjumlah 13-15, sedangkan ikan betina lebih sedikit (13-14). Tingkat perkembangan gonad ikan jantan lebih lambat dari pada ikan betina dengan indeks gonadosomatik ovarium mencapai 10 kali lipat lebih tinggi dibandingkan testis.

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.

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
