First, fish ponds mixed with about 3cm of squid summer flowers, the survival rate is low, generally only about 20% -40%, but due to less stocking, so the growth rate is faster; with a higher survival rate , But the technical requirements are also high, and the stocking density is greater and affects the growth rate; therefore, for the first time farmers, it is better to use nesting, and after a certain amount of experience is accumulated, special pool breeding will be carried out.
Second, ponds with fishery mainly based on fertilized fish are generally not suitable for raising or rearing squid, and the squid has low resistance to hypoxia and is susceptible to lack of oxygen and “floating head†and “pan-tangâ€.
Third, we must pay attention to the observation of the amount of bait fish, when it is insufficient, it should be introduced in time. It is best to set up a certain amount of tilapia and squid and reproduce larvae as a supplement source for bait fish.
Fourth, the adult pool culture: pond area of ​​5-10 acres, water depth 2.0-2.5 meters is appropriate, sets of summer flowers 50-80 tail per acre or nesting 1-15 years old fish species. Monopolize the pool: pond area should be 1-3 acres, the water depth should be able to maintain 1.2-1.5 meters, acres of summer fish 1200-1500 acres, or 500-700 tail fish.
Fifth, the pond fish farming bait fish stocking ratio: squid summer flowers directly to develop commercial fish, before the squid summer flower pond, early stocking bred 30-50 million bait fish summer or by male and female 3: A ratio of 100-150 grams of sexual mature salmon, hatched salmon fry, breed 20-30 days. For 1st instar larvae to grow into commercial fish, the stocking amount of bait should be 4-5 times of the weight of puffer fish. It is better to use white peony and pupa and bream, and also to match some grass carp and tilapia species. After June and July, it is the peak season for squid to eat, and fish should be added in time according to the growth of squid and the condition of pond fish.
Sixth, the prevention and treatment of carp disease. Should pay attention to the occurrence of bait fish and the mutual infection of carp. Therefore, it is particularly important for the control of fish diseases in bait. At the same time, squids are more sensitive to drugs. A slight carelessness may lead to the annihilation of the entire army, especially in the hot season, usually requiring low doses or stopping the use.
