High yield seedlings breeding test

First, materials and methods
1. Two Pond Ponds Located in the town of Liuhu in Dongying District, the area of ​​a single pond is 1 epoch, the water depth is 1.5 meters, and the water source is Yellow River water. It is clean, pollution-free and convenient for drainage and irrigation.
2. Before clearing the pond, all the fish in the pond shall be cleaned up, thoroughly dredged, and disinfected with clear lime.
3, after the cultivation of the basic bait clear pond with fermented waste feed water, arm arm bait, so that the water color is light green.
4. The fry transport and stocking are transported from the nursery base with oxygen in air by a plastic bag. Each bag has a body length of 2 centimeters and 6,000 pupae. It takes about 12 hours to reach the nursery pond, and the survival rate is 100%. After arrival, the bag is placed in a pond. When the water temperature inside and outside the bag is the same, the bag opening is opened so that the fish fry naturally swim into the pool. The stocking time was April 2 and the water temperature was 16.2~C.
5. Cultivate and manage (1) feed feed Feed 1 to 3 times a day for high-yielding quail special opening feed. The fish seedlings were fed once a day for the first 10 days after the lower pond, two times a day for the middle 20 days, and three times a day for the next 20 days. Due to the small caliber of the carp, feeding is slower. Each feeding is done for about 1 hour. According to the “Four Ding” principle, the conditioned reflexes of the concentrated feeding are trained and the fish eat on the water to observe the living conditions of the fish. Reduce the loss of feed, ensure timely prevention of disease and water pollution, so be sure to be patient and meticulous. Because the fry is small and frightened, try to keep quiet as you feed and take slow shots.
(2) Water quality management Due to the high fish density during the cultivation, it is easy to cause “floating head” phenomenon. Therefore, it is necessary to strengthen the inspection pond and find that the floating head immediately increases oxygen. Generally speaking, sunny days, noon, cloudy early morning to artificial oxygen. In addition, irregular phenomena (outliers, jumps, dead fish, etc.) found in the patrol pond must be inspected so that problems can be solved in time. Because the fry is too small, frequently changing the water pump suction will cause fry damage, so try not to change the water during the cultivation, add water every 5 days, inject new water 1020 cm, regularly check the water ammonia, pH, dissolved oxygen, regular Solid photosynthetic bacteria and ammonia-lowering agent remove ammonia nitrogen and nitrite. Doing so can effectively prevent the pond water from becoming over-fat, but it can also avoid the damage caused by changing the water and the excessive change of water temperature.
(3) Disease prevention and control Due to the relatively high cultivation density, due to factors such as feed, water supply, and climate, the water quality is liable to change, resulting in morbidity. Therefore, the disease is generally disinfected once every two months, and the strength is uniformly distributed at the depth of every meter per acre. 130,-,200 grams. Disinfection is usually performed at 2-3 o'clock in the afternoon on sunny days, which can effectively prevent and control the diseases that may occur in high-yield farms. Sprinkle the photosynthetic bacteria 5 days after the disinfectant is sprayed to cultivate beneficial bacteria. During the period of splashing the medicine, observe the feeding condition and the fish condition of the fry when feeding the food, so as to prevent and cure the disease in time.
Second, the results of the test early pond fish fry 2 cm in length, after nearly 50 days of intensive cultivation, on May 20 full-length average of 6 cm, weighing 3.5 grams, specifications and tidy, lively and vigorous campaign. During the cultivation period, more than 80,000 fish fry were exported from the pond, and the survival rate reached over 90%.
Third, discuss and analyze
1. It has been proved by practice that high-yield maggots grow faster and have higher demand for nutrients in feed, especially protein, vitamins and mineral salts. Therefore, we must choose high-quality feed to ensure its rapid growth.
2, in the feeding process to adhere to qualitative, timing, quantitative, fixed-point "four principles" principle. As soon as possible to cultivate the conditional reflexes of fry concentrates and increase feed utilization. Due to the small size of the high-yield pods, the requirements for the particle size of feeds are stricter, and feeds with a suitable particle size should be selected.
3, in the early fry cultivation, the density can be a little larger, with the growth of fry, to reduce the density in time to prevent the occurrence of hypoxic floating head, resulting in unnecessary losses.

Canned Sardine is made of sardines and tomato sauce, is common canned food, the production is complex. The ingredients are from our company ocean going ships, we going sea fishing, directly sea-frozen, then returned to the factory for production, processed into canned sardines. We have variety of tasty, including Canned Sardine in Brine, Canned Sardine in Tomato Sauce, Canned Sardine In Sunflower Oil, Canned Tuna in Vegetable Oil.

Canned fishes are made in our sub company-Zhejiang XingWang LongSheng Food Co.,Ltd. The company now has two factories(can branch and loin branch) and the main production equipment are: 3 processing capacity of 60 mt(materials)/day canned fish production lines; 4 processing capacity of 50 mt(materials)/day frozen cooked tuna loin production lines; 3 freezing capacity of 80 mt/day freezer rooms and 1 disposing capacity of 1000m³/day waste-water treatment plant. All the key equipment of every plant are imported from Thailand or Japan.

We will always strive to create more delicious, natural and safer marine health food.
