This technology was tested at the Aquaculture Test Site in Chuanqing Town, Gaoyou City, Jiangsu Province.
material
1. Pond conditions. An area of ​​10.5 acres, water depth of 2 meters, about 30 cm deep silt, flat bottom. Adequate water supply, fresh water, convenient drainage and drainage, 1 pump set.
2. Clear pond. There are two steps: First, clean the slope and remove the weeds; second, disinfect the drugs. Ten days before the fish enters the pool, use 150 kg of lime to clear the pond.
3. Fertilizer. After 5 days of disinfection in the clear pond, the pond water is filtered with a 40-mesh sieve to prevent wild fish and other predator organisms from entering the pond. The depth of the water is 50 cm. At the same time, 400 kg of fermented chicken manure was applied at a time to cultivate plankton, and ready-to-eat bait was prepared for the fish into the pond.
method
1. Fish into the pond. Heterophyllous silver carp seedlings from the high-yield silver grass breeding base in Chuanqing Town, Gaoyou City, Jiangsu Province. The eel and eel fry were from the Gaoyou Fisheries Breeding Farm and were transported to Tangkou through a double-layer oxygen bag. In front of the pond, place the oxygen bag containing fish fry into the pool and let it rest for 15 minutes so that the fry gradually adapts to the temperature difference. Lightly lift the bottom of the bag and slowly put the fry into the pool. A total of 105,000 fish fry were placed in the test pond, of which: 65,000 were reared on May 10, 30 thousand were reared on May 30, and 5 thousand were reared on summer May 30.
2. Feed the bait. From the 12th day after the fry hatching, homemade No. 1 mixture (20% soybean powder, 40% wheat flour, and 40% cabbage cake) was fed and 30 days later, the homemade No. 2 compound was prepared (90% of the cake and 10% of wheat flour). ). Throughout the year, it shared 11760 kg of biscuits, 630 kg of soybean powder, 1522 kg of wheat flour, a total of 13912 kg, 1325 kg of mu, and a feed coefficient of 2.1. The “four determinants†are used for feeding, that is, timing, positioning, quantifying, and quantifying, and they are fed twice a day. From 8 am to 9 am and from 2 pm to 4 pm, the daily feeding amount depends on the season, weather, and fish body. The food intake and activities are determined to account for approximately 8% of the pond fish.
3. Water quality management. The first is timely, appropriate, and suitable fertilizer. From June to August, fertilizers are applied every 15 days to 20 days. According to the water conditions, 5 kg to 10 kg of phosphate fertilizer are chased each time, so that a small amount, multiple times, and uniform splashing can be used to maintain a reasonable composition and quantity of plankton. The second is to constantly add fresh water, once every 7 days to 10 days, 20 cm to 30 cm each time, and apply lime every 20 days to 30 days (20 kg to 30 kg per mu). The transparency is controlled at about 30 cm. , to maintain water quality "fat, live, tender, cool."
4. Disease prevention and control. Adhere to the main ecological prevention, supplemented by drug therapy. In addition to doing a good job of clearing the ponds and seedlings before entering the pond, and strengthening feeding and management, during the period of “bale barley†and “Bai Luxinâ€, the external use of strong chlorine fines Quanchiposa, internal use of fish and blood baits for internal use Method to effectively control fish diseases.
Carnitine, or trans. carnitine, is an amino acid, a quaternary ammonium cationic complex, which can be biosynthesized from both lysine and methionine and is involved in the metabolism of fat into energy in the body. Carnitine has two stereoisomerism: L-Carnitine, which is biologically active, and D-carnitine, which is non-biologically active. L-carnitine (L-carnitine) is an amino acid widely distributed in the liver, especially in myocardium and skeletal muscle. Most of the carnitine required by the body comes from meat and dairy products in the diet. [1]
Carnitine is an amino acid widely distributed in the liver, especially in cardiac muscle and skeletal muscle. Most of the carnitine components required by the body come from meat and dairy products in the diet. In addition, the body itself can synthesize part of methionine as raw material, and the body needs vitamin C, iron, B6 and niacin as auxiliary factors of various enzymes in the reaction when biosynthesizing carnitine. L-carnitine is widely present in the body, especially in mitochondria. The concentration of L-carnitine was highest in the adrenal gland, followed by the heart, bone, muscle, adipose tissue and liver. Free L-carnitine is excreted in the urine. Plant-based foods contain less l-carnitine (in some cases none), as well as less lysine and methionine, the two essential amino acids that make carnitine. The l-carnitine content in animal food is high, especially in liver. Foods rich in L-carnitine include yeast, milk, liver, meat and other animal foods. Humans and most animals can also meet their physiological needs through synthesis within their bodies. L-carnitine is not deficient under normal conditions.
