There are many kinds of squid, and the fastest type of squid with long speed is the preferred culture species. In order to develop and market the squid summer flower, it is necessary to fully meet the necessary conditions for the rapid growth of the squid in the breeding process according to the unique biological characteristics of the squid. First, the pond conditions should choose ample water, convenient drainage, water quality, less silt ponds. The Cui Youxi hard bottom, the new open pond is better, about 3 acres in area, water depth of 2 to 2.5 meters, after the selection of a good pond should be thoroughly cleaned, disinfected with quicklime, mud at the bottom of the pool, there is some sink in the pool Plants have clear beaches along the pool to meet the daytime habits and growth needs of carp. Second, the stocking conditions? Qing good pond after the application of ripening basal fertilizer, add new water 0.8 to 1 meters, 3 to 5 days after the bait fry can be stocked, and a week later stocking summer carp. The dissolved oxygen requirement of squid is very high, so the density should not be too large, otherwise the squid has great disparity in growth and affects the breeding effect. Stocking should be based on squid as the main method of fish farming, according to the quality of farming conditions and the level of technical level, the general acres of about 3 cm squid summer flower 800 to 1200, when the next pond with 30ppm formaldehyde solution immersion for 5 minutes . It is advisable to go back to stocking time, not later than the beginning of June, to extend the growth period. Three, feeding conditions? One foot, should be put 20 to 30 times the bait fry, choose to slender body, no hard spines, poor swimming ability, low value live fish and shrimp as well, such as pimple, dense pimple , Spike fish, clams, clams, white clams, grass carp, etc., are palatable bait fish. Carp gluttony, there is a gluttonous process after the pond, feeding 1 or 2 times a day, as 13 o'clock and 20 o'clock, the most fierce feeding at around 20 o'clock, feeding rate is generally 7% to 15%, bait fish remaining Not less than 15% to 20%, carp swallowing specifications increase with its own specifications, it is 50% to 60% of its body length, bait increases with the fish, the eclipse is gradually reduced, can be used since the fry or make up Fish, wild fish and other methods to effectively solve the bait fish palatability, quantity, is to develop large-scale, high-yield the most reliable guarantee. 3 cm squid summer flowers, usually about to devour three or so bait fish a day, feeding can be controlled once every five days, each time the first vote of large-scale body height fish, after the vote of small-sized slender fish, bait coefficient of 4.5 to 5. When conditions permit, a suitable 0.5 to 1 kg of mussel-feeding shrimp will be added simultaneously, which will not only improve the good diet of the prawn, but also effectively regulate and improve water quality. At the end of the year, more than 10 kg of shrimp can be harvested to increase the output value of the pond. Fourth, the management conditions? 1. Qintangtang: squid on the higher requirements of dissolved oxygen, the lack of oxygen in the pool is often easy to float head, so in Wangwangwangchang season, the weather is hot and thunderstorms in the evening, should be strengthened on duty, If you find that the larvae concentrate toward the poolside, you must cut the aerator immediately. You can also take measures in advance to prevent accidental death of the oxygen-depleted floating head. This is the key to ensuring the survival rate of squid. 2. Diligent flushing: The squid prefers clear water, prefers living water, and has better micro-fluid culture. Inject new water 1 or 2 times a week to keep the water fresh, with enough dissolved oxygen, a transparency of 40 cm, and a dissolved oxygen of 4 mg/l or more. When the water in the pool is turbid, it can be splashed with alum or calcified water to clarify the water quality. The bait fish has oysters, which can control the pool water fertility, meet the high demand of the squid for clear water and high dissolved oxygen, and at the end of the year can have additional value to harvest about 100 kilograms of fish such as quail. 3. Observe groundly: Observe the situation of squid to feed on the bait fish, and judge the time, quantity, and specification of the bait fish when the bait is collected, and when it is found that the growth of the bait fish makes the pond water excessively lean, It is necessary to put some fish feed properly to ensure that the bait fish and squid grow in synchrony. If the bait fish is not eaten within 10 days after its release, it is necessary to analyze the cause to find out whether the water quality is bad or the fish is sick. Measures. 4. Diligence check: Regularly check the growth status of squid. If you find that there is not enough food or discomfort affecting the growth of the squid, you should properly supplement the squid. The carp is susceptible to diseases such as trichomonads, slugs, ringworms, grubs and other diseases before it is 10% in body length. It can be sprayed with 0.7ppm copper sulfate and ferrous sulfate mixture in the whole pool, and the effect is good.
