Abstract

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.

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 nilem (Osteochilus vittatus) is an endemic freshwater species native to Indonesia and is valued both for its therapeutic properties and its potential for processing into value-added products such as baby fish chips. However, its relatively low growth rate remains a major constraint in aquaculture development. The effect of overlapping feeding on the growth performance and survival of nilem larvae was evaluated. Spawning was conducted over three periods using hormone-induced broodstock prior to larval rearing, and fertilized eggs were incubated under controlled conditions. Larval rearing was carried out at the Freshwater Fish Germplasm Research Installation using two feeding treatments with two replicates: a non-overlapping feeding regime, in which Infusoria was administered from day 4 to 7 followed by artificial feed, and an overlapping regime, in which Infusoria was provided from day 3 to 10 alongside artificial feed from day 8 to 10 before transfer to outdoor concrete tanks. Higher absolute weight gain (0.022 ± 0.001 g), absolute length gain (0.78 ± 0.03 cm), specific growth rate (3.30 ± 0.135%), and survival rate (90.0 ± 0.89%) were recorded under overlapping feeding compared to the non-overlapping treatment (0.018 ± 0.001 g; 0.67 ± 0.01 cm; 2.76 ± 0.111%; and 86.1 ± 0.62%, respectively). Significant differences (p<0.05) were observed in absolute length gain and survival, while absolute weight gain and specific growth rate were not significantly affected. Overlapping feeding was demonstrated to improve larval performance and can be recommended as a feeding strategy to enhance hatchery productivity in nilem aquaculture.

Abstract

Corydoras julii is a freshwater ornamental fish species highly favored by both local and international markets. However, breeders often face challenges in achieving optimal egg production, which is suspected to be influenced by the type of spawning substrate used. This study aimed to determine the most effective substrate for improving the spawning performance of C. julii. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and three replications, consisting of no substrate (control, K), raffia string (T), PVC pipe (P), and Hydrilla verticillata (H). Parameters observed included egg productivity, fertilization rate, hatching rate, and larval survival rate. The results showed that the highest egg productivity was obtained in the PVC pipe treatment, with an average of 2081 ± 125.83 eggs. However, differences in substrate type did not significantly affect the fertilization rate, hatching rate, or survival rate. Water quality parameters, including temperature, pH, and dissolved oxygen, remained within the optimal range for spawning throughout the study. In conclusion, the PVC pipe was identified as the most effective substrate for enhancing egg productivity in Corydoras julii breeding without negatively affecting other reproductive parameters.
