Crayfish is a kind of aquatic product that is loved by consumers in most parts of China because of its high nutritional value and delicious meat. It is currently being farmed in most areas. So how do you raise crayfish seedlings ? Let’s take a look below.

1. How to raise crayfish seedlings?

1. Site selection

The farms should be built in areas with no pollution sources, good water quality and convenient drainage and irrigation. The construction of the breeding pond also needs to be considered, including the depth, size and shape of the pond, as well as the slope of the bottom and sides of the pond. At the same time, appropriate aquatic plants , such as water peanuts, water hyacinths , etc., need to be set up to provide shelter and food for crayfish.

2. Seedling selection

High-quality crayfish seedlings should be healthy and active, with normal body color and uniform size. The number of introduced seedlings needs to be determined based on the size of the breeding pond and the expected yield. At the same time, care should be taken to avoid introducing seedlings containing pathogens or parasites to avoid causing epidemics.

3. Feeding

Crayfish are omnivorous animals and need to be provided with rich food sources, such as plant feed, animal feed and compound feed with high protein content. Adjust the feeding amount appropriately according to the growth stage and season of the crayfish. Each feeding should be done in such a way that the crayfish can finish eating within 1 hour.

4. Water quality management and disease prevention

During the breeding process, regular water quality management and disease prevention are the key to ensuring the healthy growth of crayfish. Change the pool water regularly to keep the water fresh. At the same time, the growth status of crayfish should be closely observed. If any abnormality is found, timely measures should be taken, such as isolating sick shrimps, disinfecting pond water, feeding medicated bait, etc.

2. How to effectively prevent the death of crayfish seedlings?

1. The seedlings should be produced in the breeding ponds, and the transportation method and time should be correct.

2. When stocking seedlings, pay attention to the disinfection and water immersion of the seedlings to avoid unnecessary death of the seedlings.

3. Spray stress-relieving drugs into the breeding pond before stocking the seedlings to reduce excessive stress on the seedlings caused by changes in their own environment.

4. Feed the shrimp promptly after stocking, and salvage and bury dead shrimp promptly.

5. Ensure that the water environment in the breeding pond is suitable before stocking.

6. Do a good job in killing the natural enemies of crayfish.
