Things to note when raising tilapia

Perch is a relatively easy fish to raise, has a fairly fast growth rate, raising for 4-5 months if applying appropriate technical measures, the fish will reach a weight of 10-15 fish/kg and a productivity of 3-5 tons/1,000m2. Perch meat is very delicious, popular and has a fairly high price on the market.

During the breeding process, we need to pay close attention to the mandatory characteristics of this fish species such as:

- Should be raised with artificial breeds and especially must control the source of breeds, better yet is to create your own source of breeds to proactively follow the farming plan. When raising fry for about 40-45 days, you can filter the cage to have fish of the same size and thereby select a fish school with a high proportion of female fish so that the fish can grow quickly and achieve high productivity.

- It is necessary to feed fish with industrial pellets with high protein content of over 30% in the first 2 months and then combine with homemade food from animal by-products, however, it is necessary to follow a certain ratio (should not exceed 50% of the total amount of food) and need to feed fish continuously because if the fish are not fed enough quantity and quality of food, the fish will go into early sexual maturity and will grow slowly and ineffectively.

- For every 1,000 square meters of pond, farmers need to prepare capital of about 100 - 120 million VND.

- When the tilapia reaches the stage of being sold, it cannot be delayed. If it is prolonged, the fish will hold eggs and stop growing, or the fish will eat less and become thin… usually traders will criticize and lower the price.

- Like other types of fish, raising tilapia also requires seasonal arrangements to avoid selling in the 8th, 9th, and 10th lunar months, because this is when there is a large amount of natural fish, so the fish cannot be sold at a good price.

- Although it is a species that can live well in harsh environments such as dirty stagnant water and low dissolved oxygen content in water..., when raised at high density in ponds, it is necessary to periodically change clean water regularly. On the other hand, fish often develop some diseases such as: Hemorrhage, intestinal diseases, slime mold, and some other diseases, especially during the changing seasons... These diseases are mainly caused by bad water environment. Therefore, during the farming process, it is necessary to pay attention to keeping the water in the pond really good to prevent diseases for fish, especially in the middle of the season onwards, because at this time the amount of waste from fish and layers of dead algae accumulate at the bottom of the pond is very large. The most obvious manifestation is when the pH increases above 7.0 (the best pH for tilapia is from 6.5 - 7.0). Therefore, during the farming process, it is necessary to pay attention to using bottom treatment agents such as zeolite or other biological products to treat ponds.
