Carp is a rare freshwater fish in the world. Its artificial breeding has received more and more attention from people. Now we will introduce new technologies for the rapid development of catfish cages as follows:
Net cages and their settings The fast-growing cages of squid are generally woven from polyethylene threads and have a specification of 40 mx 4 m x 2.5 m. The size of the mesh depends on the size of the stocked carp species, and is based on the principle of not escaping fish, facilitating the exchange of water quality, and not leaking baits on the bottom mesh. If stocking more than 100 grams of fish per tail, the mesh size is 2 cm to 3 cm. Due to constant feeding, cages are suitable for open type, and the setting method is frame floating. The cage should be set up in a place with good water quality and a water depth of more than 3 meters. It should also have conditions such as micro-flowing water, sheltering, sunny, and wide water surface. Large reservoirs should be suitable for Kuwan, and small reservoirs should be equipped with cages not far from the dam.
The optimum temperature for the growth of the fish species and their stocking carp is 20°C～25°C, and the stocking time is preferably from the end of May to the beginning of June. The larger the size of the stocking species, the better, generally from 100 g to 120 g per tail. Stocking densities range from 35 to 40 per square meter. When stocking, choose 6 to 8 o'clock in the morning. At this time, the temperature difference between the temperature of the fingerling and the water temperature of the reservoir is small.
The main features of fast-growing bait and its feeding cages are the feeding of fresh animal foods and artificial feeds. With the bait protein content of 40% to 45%, the main raw materials are fish meal, silkworm cocoon, meat and bone meal, enteric coating powder, blood meal, yeast, dried cakes, wheat, corn and so on. Its reference formulation (%): fish meal 37, silkworm cocoon 15, blood meal 15, yeast 4.5, dried cake 5, wheat 17, corn 4, additive premix 2, binder 0.50, weighed according to formula, crushed, processed into 2 Millimeter to 3 mm particle size, dry storage. Here we must emphasize two points: First, the raw materials should be crushed very fine, it is best to achieve more than 40 mesh fineness; Second, the stability of the particles in the water required to maintain 1.5 hours to 2 hours does not disperse, that is to say must use Better performance adhesives. After the fish is put into the box, the feeding is stopped for 1 to 2 days in order to adapt to the cage environment. After 2 days, a small amount or multiple shots can be added to the food table placed around the cage. (0.3 to 0.4 square meters per cage can be used 4 to 6 bamboo screens 0.2 meters deep; suspended in the box Near the bottom of the body, the fish were fed and fed 5 to 6 times a day, so that the fish species could achieve the artificial diet of pellets after 7 days, and then enter the normal feeding stage. The daily feeding amount is generally 4% to 5% of the fish weight in the box. Carp has nighttime feeding habits, so the amount of feeding in the afternoon should be more appropriate. How to determine the appropriate amount of feed it? First, according to the daily feeding rate to calculate the daily amount of food. The second is to check how much residual bait is left. The third is to observe carefully the changes in the shadows of the fish in the “two layers of water†under the feeding point when feeding. Usually at the beginning of feeding, fish intensively catch food, the shadow is large, the water waves in the box roll, and after the feeding of high tide, the shadows of the fish become smaller or disappear, the water surface tends to be calm, and the feeding should end here.
Management and its measures The cages should be guarded by dedicated personnel and adhere to multiple inspections every morning, evening and evening to observe fish conditions and water conditions. In particular, flood prevention should be used to wash away cages, and cages should be grounded to prevent enemies from repelling water. Damaged cages, anti-sediment debris cages. In addition, cages should be cleaned every 10 days or so, especially after the flood, to remove debris and excess algae, and to keep the exchange of water inside and outside the cage open.
Fish diseases and their prevention and treatment The surface of the catfish is made of bone plate, the natural predators are less, the history of artificial breeding is short, and its epidemic and fulminant diseases are rare. The existing reports are mostly caused by water quality deterioration, but they should still be done. Good water quality control, adherence to prevention-based disease prevention work. The specific approach is: soaking the water in the cage before using water or bleaching lime, and 7 days to 10 days in advance of the water, let the algae attached, so as not to damage the skin after the fish into the box. When the fish enters the box, they are disinfected first, and soaked with 3% to 4% of salt water for 15 minutes to 20 minutes. Usually, the dead and injured fish must be picked up and removed to prevent contamination or cross-infection. For every 15 days to 20 days, use 2 to 3 kg of lime water in each box and the nearby waters, once a day, for 3 consecutive days. Every day must remove the residual bait, wash the table and drying, the surrounding table should be regularly sprinkled with quicklime water disinfection, in order to enhance the feeding of carp and reduce the occurrence of fish disease. If trichodiasis, oral filariasis, and tongue cup disease occur during feeding, potassium permanganate may be used for 2 mg per liter or copper sulphate for 75 mg per liter. If bacterial enteritis occurs, 0.2% bait containing baicalin can be fed and cured for 5 days to 6 days.
