How to Raise Pangasius? Detailed Guide to Farming Methods and Techniques
Pangasius is an important freshwater aquaculture species in Southeast Asian countries, with delicious meat and high nutritional value. So, what farming methods are there for pangasius? Let's take a look!
1. Feed Feeding
During the fry rearing stage, pangasius is mainly fed meat-based feed. When it grows to the middle and late stages, the feed is switched to pellet feed. The growth of pangasius has relatively high protein requirements, so the feed we provide must contain relatively high protein, but the balance of the remaining nutrients must also be ensured. Feeding begins one day after the fry are stocked, at least twice a day. The feeding amount depends on the total weight of the fish, generally about 1/10 of the fish weight. When pangasius grows to the late stage, one additional feeding per day is required. During feeding, appropriately adjust the feed composition, timing, method, and so on according to the growth and feeding conditions of the pangasius.
2. Pond Patrol and Observation
Patrol the pond at least once a day, observe the environment around the pond and the growth of the fish, promptly discover various abnormal conditions, and take corresponding measures at any time. For example, if signs of disease are found, immediately remove the suspected diseased fish, disinfect the fish pond, examine the specific disease of the diseased fish, carry out isolated rearing, and put them back into the original pond when growth resumes. Change the water at appropriate times, then determine the water exchange amount according to various factors such as water quality and transparency.
3. Water Quality Management
As pangasius grows, its food intake gradually increases, which also brings some problems. When food intake increases, the excrement and leftover feed of pangasius affect water quality, causing water quality to deteriorate. Therefore, we must promptly adjust it according to the specific water quality conditions. Pangasius generally lives in waters with small fluctuations and likes to swim up and down, so we should make the pond water as deep as possible. When changing water, pay attention to the water temperature and do not change too much water, which would cause the water temperature to drop and affect the growth of pangasius. The pH value in the water must be well controlled. Being too acidic will aggravate the occurrence of disease. Keep the pH value on the alkaline side, appropriately adjust the acidity and alkalinity, and create a good growth environment.
4. Disease Prevention and Control
There are many common diseases of pangasius. For disease prevention and control of pangasius, prevention work must be done well, with control as a supplement, because the pond water is relatively deep, we cannot discover problems in time, and it is also difficult to control them. Therefore, the water temperature must be well controlled to ensure it remains within the range suitable for pangasius growth. Then regularly sprinkle quicklime powder over the pond for comprehensive disinfection, promptly remove leftover bait, appropriately add preventive drugs to the bait, and take response measures for various adverse weather conditions to prevent mechanical damage to the fish body that could produce wounds.
