Hybrid quail is produced by the hybridization of squid and squid, and is currently the most growth-dominant farmed squid. Its breeding season is from May to July, when the water temperature is between 16 and 24°C, it can lay eggs successfully. After one month, it enters the juvenile stage. In the pond culture process, we must grasp the following technologies:
As early as possible domesticated squid is a mild meat-eating fish, likes to eat leeches, leeches, mosquito larvae, Artemia and bottom wild fish etc. for a lifetime, and it is very good to use these live baits to cultivate fish species. However, in large-scale production, in principle, only live baits are opened and domesticated as soon as possible, and then cultured with compound feed.
In general, the fry seedlings that are sold to the farmers on the seed farm are domesticated. If no domestication is performed, tame food should be taken before feeding. The method of taming is that the squid starts feeding 2 days after entering the pond and feeds the biological live food first. After 3 days, it feeds the fresh or frozen low-quality mixed fish. After 3 days, it feeds the mash mixture and changes the feed after 3 days. Formulated feed.
Preparation of feedstuffs for preparation of feedstuffs The preparation of paste feeds is to be processed into pulp pastes with low-quality wild fish and then mixed with fishmeal, flour, bran and other compound feeds to produce a crude protein content of more than 45% and a fat content of 10% to 20%. The carbohydrate content of about 20% of the nutritional more comprehensive feed.
The nutrient composition of the formulated feed is basically the same as that of the mixed feed. Here are a few mature recipes (see attached table). At the time of production, various raw materials were first crushed, passed through a 100-mesh sieve, and granulated into hard particles. The fish of the year was fed a feed with a particle size of 0.2-0.5 mm, and the fish of the second age was fed a feed with a particle size of 1.5-5 mm. It is also possible to directly feed the appropriate size of salmon feed. Note that it must be ensured that the feed is fresh and not deteriorated. Feeding 4 times a day at 7 o'clock, 12 o'clock 30 o'clock, 10 o'clock, 21 o'clock 30 o'clock, the feeding amount is 0.5% to 2.0% of the fish's body weight, and adjusted according to water temperature and season. . Feeding using hand sprinkler method, evenly sprinkled in the pool, feeding time 10 to 15 minutes, so that the fish eat 80% full appropriate.
Adjust the water quality and water temperature The suitable water temperature for hybrid quail breeding is 14-26°C, and the optimal growth water temperature is 17-22°C. If the water temperature is lower than 14°C or higher than 26°C, the growth is slow. Therefore, in the breeding process, the water temperature should be controlled below 30°C. In the summer season, the temperature of the pond water is easy to rise. Therefore, the water depth should be kept above 1 meter and the water should be flushed frequently. Cover scaffolding above the pond and shade it with a shade net. Where conditions permit, it is best to extract the reservoir bottom water, so that the pond forms a flowing water environment. In winter, when the water temperature is 5°C, the hybrid quail can still feed and grow. In winter, the depth of water should be kept at about 1 meter, and plastic sheds should be built on the ponds, covered with special black film for aquatic production to avoid frost in the pool. Drain it once a week.
The requirements of dissolved earthworms for dissolved oxygen in water are significantly higher than those of the four major ones. When the water temperature is between 18 and 22°C, if the dissolved oxygen in water can be maintained above 6 mg/l, the appetite of the carp is strong and the growth rate is fast. Therefore, in the still water pond culture, change the water once a day and change the water volume by 1/4 of the pool water. It is necessary to remove the residual baits and feces in the pool in time, increase the amount of water in the summer, and discharge it once every 2 to 3 days. Flowing water ponds should also be regularly drained and washed twice a week. Each time the sewage is discharged, 4/5 of the water should be drained, and the water should be drained while cleaning, and then the new water should be refilled.
