Key Points of Farming Management Techniques for Whiteleg Shrimp

Whiteleg shrimp, also known as Vannamei shrimp, has an average lifespan of more than 32 months and a high yield per unit area, making it very popular among farmers. So,what farming management methods are there for whiteleg shrimp?Let's take a look!

1. Toxin-free testing

Farming whiteleg shrimp also requires concern about contracting infectious diseases that lead to reduced yields. To ensure that the shrimp fry carry no toxins or pollutants and to avoid viral infectious diseases, when selecting fry, the fry should undergo toxin-free testing, and all fry must meet the required standards. Moreover, before stocking, the fry should be placed in batches in plastic bags and floated in the pond for about half an hour, so that the whiteleg shrimp gradually adapt to the pond environment, and then be released into the pond in batches. This ensures that the fry quickly adapt to the pond, improves the survival rate, and reduces losses.

2. Farming density

When farming whiteleg shrimp, many farmers, in order to increase yields, disregard the size of the pond and its capacity when stocking fry, and simply release a quantity exceeding the pond's carrying capacity all at once. This is wrong. Overstocking causes whiteleg shrimp to compete for feed, making it impossible to ensure that all whiteleg shrimp can eat enough feed and develop well. Therefore, to control the density in the pond properly, a certain number of mesh grids can be placed in the pond, with a fixed number of shrimp stocked in each grid. This not only reasonably controls the farming density of whiteleg shrimp but also makes management easier and improves the effectiveness of stocking whiteleg shrimp. Only by reasonably controlling the stocking density can farming results be improved.

3. Rational feeding

Farming whiteleg shrimp necessarily requires artificial feed. When feeding, two principles must be grasped. First, when feeding whiteleg shrimp, reasonable choices must be made to ensure that the feeding amount can meet the growth needs of the whiteleg shrimp. The feed amount must be neither too high nor too low. Too high will cause leftover feed to spoil and pollute the water quality, affecting the growth of the whiteleg shrimp to a certain extent. Too low will fail to provide the nutrients needed for the growth of the whiteleg shrimp and affect the quality of the shrimp. Therefore, the effectiveness of feed feeding should be strengthened. Second, feeding time also has certain requirements. The number of feedings should change according to the growth needs of the whiteleg shrimp, and the feeding time should conform to the eating habits of the whiteleg shrimp.

4. Increasing dissolved oxygen

If the dissolved oxygen in the pond is insufficient, the whiteleg shrimp will suffer from insufficient oxygen and suffocate to death, greatly reducing yields and also affecting the economic interests of farmers. The oxygen content in the pond should be checked regularly, and corresponding measures should be taken promptly according to the oxygen content in the pond. Oxygen can be injected into the pond through oxygen supply equipment, and then the oxygen content in the pond water should be tested to see whether it meets the standard. Once the required oxygen content is reached, oxygen supply should be stopped immediately. It should be noted that with seasonal changes, the oxygen content in the pond also changes, so oxygen content should be increased in a timely manner to improve water quality.
