• An ancient fish with a pair of barbells. Large scale. • Carnivorous freshwater. Benthos that lives in the tropics. 24 ° C-30 ° C • Young individuals eat insects on the surface of the water, and adults catch fish, frogs and large insects. • Inhabits slightly muddy, slow-flowing streams, some of which occur in tannin-stained black water, forested streams, and slightly acidic water. • Mouth breeders and males carry eggs and larvae into their mouths until the yolk sac is completely absorbed.


• Communicate knowledge and experience of natural breeding and nursing practices in Surat Thani's Asian Arowana hatching system.


From the jungle to the research center • Wild parent birds from Klongsen, the Khao Sok Natural Park in Surat Thani, have been collected since 1986. • Relying on the breeding of chicks of unknown gender and the natural breeding of all captured fish, a major step towards domestication was introduced into the soil pond, but fortunately breeding The first success of was in 1988 and had 29 offspring.


Naturally Induced Breeding in Soil Ponds • Water-flowing soil ponds, 800-1,600 m2 and 1 m deep, are commonly used for natural breeding. • Paddle wheels are also needed to increase night and cloudy DO and water circulation. • Approximately 80 captive breeding pairs are stocked, 45 cm long, 1.5 kg in weight, and have a male-female sex ratio of 2: 1. • Adult fish, athlete's foot, and some auxiliary pellets are fed daily, followed by weekly courtship inspections along with fish spawning behavior.

Spawning behavior and fry harvesting • Courtship and mating occur days after the first heavy rain of the year. • At night, the eggs are fertilized and the males scoop the eggs into their mouths to hatch, allowing the fry to swim and survive independently. • Half-developed larvae are removed from the male mouth, collected bimonthly and cultured in a glass aquarium. • Dark males need to be caught carefully. Normally, 20 to 35 yellowish fertilized eggs are properly collected from a single broader.

Nursing techniques • Acriflavine solution is applied for infection prevention and aeration. Live insect larvae and fry of fish are rarely fed. • The larva remains with a large yolk sac for the first few weeks and is always lying at the bottom of the aquarium. The yolk sac is completely absorbed and the larvae are free to swim about 6-8 cm in length at 8 weeks. • Water Boatman (Corixa) is the most popular meal for the youngest children in the first three months. To increase growth rate, elders 10-12 cm can be fed live freshwater shrimp, juveniles, sliced ​​fish meat

Return to Nature • After 6 months of free swimming, it is suitable for returning juveniles about 20 cm in length to the wild according to a native fish rehabilitation program. • Partial water exchange of about 30% of the total amount every 3-4 days, use saline and 1% salt to prevent fry damage due to fin rot, and monitor water quality every other week Recommended to use
