HYBRID PANGAS FISH HARVESTING PANGASIUS FISH FARMING | FISHERMAN CATCHING PANGAS SEED IN POND. Pangasius spp is commonly called as river or silver stripped catfish, Siamese shark, sutchi catfish, or swai catfish. This fish species live in freshwater and endemic to the Mekong basin. It is a riverine catfish belonging to the members of the family Pangasidae. It exhibits fast growth when cultured given a good environment. Pangasius Farming and Production Guide
Pangasius Farming and Production Guide:- Pangasius spp is commonly called as river or silver stripped catfish, Siamese shark sutchi catfish, or swai catfish. This fish species live in freshwater and endemic to the Mekong basin. It is a riverine catfish belonging to the members of the family Pangasidae. It exhibits fast growth when cultured given a good environment.
Pangasius Farming and Production Guide:- It is cultured due to its strong market demand, fast grower, few countries dominate the culture production, and being the 3rd most important freshwater fish group within aquaculture sector. Pangasius is now cultured in several countries in the world like Thailand, Nepal, Pakistan, India, Bangladesh, Vietnam, Laos, Myanmar, Indonesia, and Cambodia.Pond Preparation - Pond preparation is the same as general preparation for fish ponds.
Pond Management:- Feeding management. Pangasius can be fed with kitchen waste, rice bran or pelleted feeds recommended for faster growth and better fish qualit at a rate of 2.5% of their average body weight and will be adjusted bi-weekly. Feed Conversion Ratio averages to 1.5:1 which makes it a suitable for culture. Pangasius is omnivorous (both plants and animals during their first year and become herbivorous for the following years.
Since they are omnivorous, the Pangasius Catfish or Iridescent Shark Catfish will generally eat all kinds of live, fresh, and flake foods. To keep a good balance give them a high quality flake food or pellet everyday. Feed brine shrimp or blood worms. As they get older they loose their teeth, and like the Pacus, become more and more vegetarian. Home-made mixture of boiled vegetables, rice-bran and broken rice may also be used for feeding.
Water management. Water is important for all fish, so optimum conditions for certain parameters of water should be the primary factor to consider in engaging to fish culture. Water quality parameters like pH (6.5-7.5), Dissolve Oxygen (DO) (0.1 mg/l), Temperature (25-30° C), Salinity (2 ppt) and water depth (1.5-2m). These should be maintained to get a better yield for the culture of Pangasius spp. Pangasius spp. is an air breathing fish thus, they don’t need to have a much higher DO in the water column.
Sampling. Sampling is done to monitor the growth of stocks and to compute feeds to be given to the stocks for the following days. This is also done to see if the stock reaches its marketable/harvestable size. Since Pangasius spp. is fast grower fish, sampling is mandatory.
Harvesting can be done in partialselective harvesting or total harvesting. Pangasius spp. can be harvested for about 5-6 months of culture period. It can reach the weight of 1-1.5 kilogram in 5-6 months culture given the proper pond management.
