Feeding and management of Penaeus vannamei

Penaeus vannamei, also known as Penaeus vannamei, has an average life span of more than 32 months and has a high yield, so it is very popular among farmers. So, what are the feeding and management methods of Penaeus vannamei? Let's get to know it together.

1. Non-toxic testing

Culture of Penaeus vannamei also needs to worry about the reduction of production caused by some infectious diseases. In order to ensure that shrimp seedlings do not have any toxicity and pollutants and avoid viral infectious diseases, shrimp seedlings should be tested for non-toxicity when selecting seedlings. To ensure that all shrimp seedlings can meet the target, and before stocking, shrimp seedlings should be placed in a plastic bag in a pond for about half an hour. Make the white shrimp gradually adapt to the shrimp pond environment, and then put into the pond in batches, which can ensure that the shrimp seedlings quickly adapt to the shrimp pond, improve the survival rate and reduce the loss.

2. Culture density

When many farmers raise white shrimp, in order to increase the yield, regardless of the size and capacity of the shrimp pond, the stocking in the shrimp pond exceeds the bearing range of the shrimp pond, which is not right. Stocking too dense will lead to the competition for feed of Penaeus vannamei, and there is no guarantee that all white shrimp can eat enough feed to ensure good development. Therefore, in order to control the density in the shrimp pond, we can put a certain number of grids in the shrimp pond and put a fixed number in each grid, which can not only reasonably control the culture density of Penaeus vannamei, but also facilitate management. improve the effectiveness of white shrimp stocking, reasonable control of stocking density, in order to improve the culture effect.

3. Reasonable input and feeding

Artificial feeding must be carried out for the culture of Penaeus vannamei, and two principles should be paid attention to. First, reasonable selection should be made when feeding Penaeus vannamei to ensure that the feeding amount can meet the growth needs of Penaeus vannamei. Feed feeding can not be too high or too low, too high will make the residual feed deteriorate and pollute the water quality and affect the growth of Penaeus vannamei. Too low can not meet the nutrients needed for the growth of Penaeus vannamei and affect the quality of Penaeus vannamei, so the effectiveness of feeding should be strengthened. Second, the feeding time also has certain requirements, and the number of times of feeding should change with the growth needs of Penaeus vanname. the feeding time should be in line with the feeding habits of Penaeus vannamei.

4. increase the amount of dissolved oxygen

If the dissolved oxygen in the shrimp pond is insufficient, it will lead to the suffocation of white shrimp due to insufficient nutrition, which will greatly reduce the yield, and will also have an impact on the economic interests of farmers. It is necessary to regularly check the oxygen content in the shrimp pond, according to the oxygen content in the shrimp pond, timely take corresponding measures, you can inject some oxygen through the oxygen supply equipment in the shrimp pond, and then test the oxygen content in the pond water to see if the oxygen content is up to the standard. To reach the required oxygen content, the oxygen supply should be stopped immediately. It should be noted that with the change of seasons, the oxygen content in shrimp ponds also varies, so it is necessary to increase oxygen content in time and improve water quality.
