The use of non-feeding cages for the cultivation of calyx is an effective breeding model for the full use of biological resources of water and the reduction of aquaculture production costs. The technology is now described as follows: First, cage structure General use of polyethylene mesh woven into 4 meters 6 meters 2 meters, 4 meters 7 meters 2 meters or 4 meters 8 meters 2 meters rectangular closed floating cage, net single layer, mesh size should be determined to break a head Do not run fish as a principle. Second, the cage settings Net cages should be installed in areas sheltered from the wind, water quality, rich plankton, and non-polluted water quality. They are generally selected at the reservoirs and reservoirs in the upper reaches of the reservoir. The water level in the cage setting area should not be too deep, with 5-8 meters being better. When the depth is too deep, the number of food organisms will be insufficient, which will affect the normal growth of the fish. At the same time, there must be micro-flowing water with a flow rate of no more than 0.1 m/s. In general, in the fertilized water areas where food organisms are abundant, the area of ​​the cages does not exceed 1% of the total area of ​​the set-up area. When the water quality is relatively thin, the area of ​​cages does not exceed 0.5% of the total area of ​​the set-up area. If there are many cages, multiple boxes can be set in series, with 5-10 each, with a spacing of not less than 10 meters and a group spacing of not less than 50 meters. The purpose is to increase the volume of water exchange to promote the growth of calyx. When fixing the cages, either as a single cage or as a unit, it is also possible to fix the ropes on both banks of the bank. Third, fish species The cages should be launched 7-10 days before the fish species are stocked. This will allow the nets to grow a little longer on the algae, making the nets smoother and less likely to scratch the fish. The time for the fish species to enter the box can be selected in the autumn or early spring, when the water temperature is appropriate, the scale structure is relatively tight, and the survival rate of the fish species is also high. Before entering the box, the fish species must undergo strict body surface disinfection. The specific operation depends on the strength of the fish species, the water temperature and the concentration of the liquid medicine. If any abnormality occurs, the fish should be stopped immediately. The longer the breeding cycle, the lower the economic benefit, so it is necessary to stock large-size fingerlings to shorten the breeding cycle. General stocking specifications are 18-23 cm in 1 year old fingerlings. The stocking density should be determined according to the condition of the water body. In general, the appropriate stocking density is 15-20 tails per square meter. Fourth, daily management The cage inspection will be combined with the regular inspections and regular inspections. Check once a week. Temporary inspections are required after heavy rain and floods. The focus of the inspection is on the area 30 cm below the water surface. This is where the water rat is likely to bite the net. After the cage cleaning cage is launched, it is easily attached by some filamentous algae and other organisms to clog meshes and affect the exchange of water bodies. The more the water quality is, the more the number of attached organisms is. The smaller the mesh size, the more serious the degree of enrollment is. Timely change of the box as soon as possible to replace the large mesh cage is the key to the success of the bait cage. According to the growth situation of calyx in cages, the stocking density in the cages should be continuously reduced, and they should be transferred from small mesh cages to large mesh cages. This will increase the exchange of water inside and outside the cage and promote rapid fish growth. Grow. Reasonable mobile cages should promptly move the cages according to the changes in the water level of Hongxun, the quality of the water, and the abundance of food organisms, avoid the unfavorable environment, and select suitable sites to ensure the normal growth of fish. Disease prevention and control Under normal circumstances, do not feed bait cages less disease, but easy to infect the anchor head, can be combined with hanging and splashing methods to ensure the healthy growth of fish. The fresh and natural taste is always attractive to people. When you are confused, drowsy and need to relax, if you take a few minutes to feel the aroma of the fruit, the situation will be completely different. As you know, blueberry flavor has always been popular with people. Therefore, we have developed and produced blueberry-flavored cigarette substitutes to help people feel the comfort of nature anytime, anywhere.
