The use of squid summer flowers (or slightly larger specifications) to directly develop commercial fish is currently a popular form of farming.
1. In order to ensure the survival rate of the breeding stock for the stocking of fingerlings, the stocking specification must be more than 3 cm. Generally, 3 to 4 centimetres of puffer fish should be stocked with 15,000 to 25,000 tails per hectare.
2. Sources of bait fish can be cultivated through the following ways.
1 Cultivation pond cultivation: In the early 15 to 20 days before the puffer fish species are stocked, the pre-harvest bait fish are cultivated in the pond. Feeding bait fish 7.5 million to 12 million tails per hectare; In order to reduce the cost of bait fish, some fast-proliferating bait fish parents can be mixed in the carp pond, such as 3000-6000 pairs of tilapia or 2 7-year-old squid 7500 per hectare. At the end, the progeny of their breeding are used as live bait fish for carp; the pond can also be divided into two parts by using a moderately-dimensioned dilute net. While raising the carp while raising the bait fish parent, the juveniles that they breed can pass through the dilute net to become crickets. The fish's diet, bait fish parent breeding is best to use enhanced cultivation methods.
2 supporting pool cultivation: 1 hectare carp single nutrition pool needs to be equipped with 3 to 4.5 hectares bait fish ponds, arrested in batches, according to the needs of sparse, to ensure the bait fish and carp synchronization growth. The density and feeding amount should be adjusted to control the growth and specification of the bait fish.
3 Natural waters fishing: Squid farms are close to lakes, reservoirs and other large surface waters, and can use abundant bait fish resources as a supplementary source for carp bait.
4 Purchase: In the case of bait fish production, in case of low flower rate, disease, or severe weather, etc., baitfish should be purchased in time to avoid affecting squid farming.
3, bait feed in the higher water temperature, the rapid growth period of carp, it is best to feed the bait once a day, after September the water temperature decreased, the carp feed decreased, can be fed 5 to 7 days or half a month The feeding amount is based on the principle of maintaining a certain bait fish density in the water body and increasing the predation opportunity of the squid. The specification of bait fish is 30% to 59% of the carcass length. The palatability is good. At the same time, it is necessary to check the feeding and growth status of the carp. The amount of bait fish used in the baitfish should be matched with the bait fish of different specifications to ensure that the carp is kept. Under conditions, the food is adequate and palatable. The feed fish must first be disinfected.
4, water quality control of carp special pool, the entire breeding process of dissolved oxygen in the water to keep at least 4 mg / liter above, but also in the carp special pool with aerator. End of spring and summer every day at noon from 12 to 15 o'clock to start oxygen, in case of special weather, the next night boot to the sun. Lime water is regularly splashed to regulate water quality.

In agriculture, Estrous Synchronization is used (particularly in the dairy and beef industries) to facilitate breeding by artificial insemination. We have Progesterone Injection, Cloprostenol Sodium Injection and Testerone Propionate Injection and Estradiol Benzoate to solve farmers' different difficultites in aninal 's estrous synchronization.
