Natural Breeding of Snakehead Fish (Channa striata) On Concrete Ponds in Cangkringan Center For Aquaculture Technology Development Special Region of Yogyakarta

Tilapia fish is much in demand because it has several advantages such as its distinctive taste that makes tilapia delicious after being processed in any way. Tilapia has the potential to be used as an export commodity in the form of fish fillets and the price is relatively cheap. The climate situation and the extent of freshwater fishing land are contributing factors in the development of tilapia cultivation in Indonesia. One of the efforts to increase efficiency and productivity in cultivation is fish spawning activities. Spawning activities are important for producing seeds or larvae. Female fish are 300 to 400 g and for males, 400 to 500 g, aged 5 months. Tilapia can colonize weighing 250 g and age 4 to 6 months, meaning the parent used in this study has been following the required. The maintained parent is a healthy, unformed, and complete morphological parent (SNI 01-61412009). The purpose of this study is to improve the quality of Tilapia fish seeds produced by the Mina Ayu Group of Tabanan Regency of Bali Province by a selective breeding method. Male and female tilapia broods are kept separately in hapa measuring 5x5x1m. In shelters, for the acceleration of gonad maturation before the fish are stocked in the spawning pond. The feeding given during maintenance is 2 to 3%. Individual selection methods can improve the quality and survival rate of tilapia fish larvae. The absolute length increased 1.5 cm and weight increased 0.950 mg/day with a survival rate of 80% to 90%.

Background: With remarkable growth in aquaculture, the need for system diversification and species diversification has been demanded by the producers to gain fruitful output in terms of profit. Striped murrel, Channa striata has been identified as a suitable species for modern aquaculture systems in terms of species diversification due to their fast growth rate, air-breathing nature, higher market price and consumer acceptance. The major bottlenecks in seed production of murrel are captive maturation and short spawning window. To overcome these problems, an attempt was made to achieve early gonadal maturity of striped murrel in captive conditions by intervening in the brooder rearing habitat. Methods: In this regard, four habitats were tested in duplicates, namely T1 - Tank with clean reservoir water without macrophytes and soil base, T2 - Tanks provided with floating (Water hyacinth, Eichhornia sp) and submerged (Waterthyme, Hydrilla sp) aquatic macrophytes without any soil base, T3- Tanks provided with only soil base (15-20 cm) without any macrophytes and T4 - Tanks provided with both soil base and macrophytes. Result: At the end of the three-months rearing phase, the fishes provided with macrophytes and soil base (T4) resulted in early maturation characterized by an egg size of around 1.29±0.21 mm and the majority of late granular stage oocytes and spermatozoa in ovary and testes, respectively. The results concluded that providing a bottom soil base of 15-20 cm and covering the 20-30% water spread area using aquatic macrophytes in the brood rearing tank helped in the gonadal maturation of striped murrel during pre-monsoon in captive conditions.
