How to raise shrimp seedlings

Shrimp seedlings should be released on cloudy or rainy days to avoid direct sunlight. After entering the pool, they are fed with mixed fish or minced meat for the first three days, and can be fed with other bait a month later. The amount and time of feeding are determined by the scale of feeding. In addition, special attention should be paid to the following points when releasing shrimp fry:

1. Stocking time of shrimp fry

There are 5 ~ 100000 shrimp fry per mu, the specification is more than 1.5cm, and the time should be from June to July. The stocking of shrimp is 2025kg / mu, 100000kg / kg, and the suitable time is from October to December.

Of course, the earlier the time of stocking, the better. The lobster seedlings entered in early May are all propagated around September last year and hatched before and after overwintering. These lobster seedlings can mature and reproduce around September this year, and most of the lobster seedlings entered after June 10 will mature and reproduce around May next year. Therefore, in order to obtain better culture benefits, it is necessary to enter the seedlings early, which is helpful to provide the culture benefits.

two。 Matters needing attention in stocking

Shrimp breeding should be carried out in cloudy or rainy days, in case of sunny days should be carried out in the morning and night, so as to avoid direct sunlight and affect the survival rate. Shrimp fry should be fully released at one time.

3. Species of silver carp with flowers

There are 80 million silver carp species per mu of shrimp ponds, with a specification of about 30 / kg, and 200 silver carp summer flowers per mu. The stocking of silver carp must be 10-15 days after the stocking of shrimp seedlings in order to ensure the demand for food organisms of green shrimp. The first is to adjust the water quality, and the other is to make full use of the water body to increase the income of fish.

4. Disease prevention

The ability of disease resistance is strong, so it is also the key to enhance the physique of crayfish in the process of disease prevention. Crayfish belong to crustaceans and molt frequently. Timely supplement of calcium in the pond is conducive to the recovery and enhancement of crayfish physique.
