Trout farming increased yield

<

Carp is a tropical fish, with large individuals, less prickly flesh and flavour. It is known as "Ochimusa," and it has good properties such as fast growth, wide appetite, and few diseases. It is an excellent source of freshwater fish. Varieties, but its disadvantage is poor cold resistance, when the water temperature drops below 7 °C easily frozen to death, so the growth period is very short, only 5 to 6 months of the year, because in the natural waters can not winter (except Guangdong and Guangxi), so In the season of fishing season, the market for fresh fish is highly concentrated, causing a backlog of fishery products. The price is low and the benefit is not high. In addition, the killing of squid during the breeding process is serious, which greatly affects the increase of stocking density and yield. However, if you use some production tips and use scientific methods to farm squid, you will get twice the result with half the effort.

1. Two levels of seedlings. The newly-fed fish fry have weak resistance and different specifications; if they are put directly into the big pond, they will have a large range of fish fry and consume more energy, and the bait they feed will be hard to eat, resulting in waste. It will pollute the water. However, if two-stage seedlings are put in place, they are first intensively reared in small ponds and then put into the pond for feeding. This will not only make it easier to manage, but also allow fish fry to better adapt to the new environment, and easily get enough food in small ponds to promote its rapid growth. When the fry cultivated in Xiaotang reaches 10-15 cm, large species of fish can be selected from the pond and put into the pond for breeding. The small species of fish remain in the small pond for intensive cultivation, so that the species balance can be developed. Consistent. This avoids the phenomenon of large fish eating small fish in the breeding process, thereby effectively increasing the survival rate and unit yield of the fry.

2. Reasonably feed the bait. Carp is an omnivorous fish, bulimia, so it is necessary to correctly grasp the amount of feeding, so that how much fish in the pond to vote how much material to prevent blind feeding. At the same time, it is necessary to implement sub-point feeding, even bait, small meals, enough to feed enough to prevent inequality, and there is polarization. At the same time, in the initial stage of fry cultivation, animal feeds should be used as the main, and intensive cultivation should be carried out. With the growth of fish, some plant-based feeds can be gradually transferred to combine animal and plant feeds. The daily feeding amount should be controlled at about 5 to 8% of the total fish body weight, and the amount of feeding should be adjusted every other week or half a month to make the amount of feeding more reasonable.

3. The implementation of arrests. Due to the fierce gluttony of squid, when feeding, the big fish often catch food first, while the small fish can't eat food, resulting in an increasing gap between the size of the fish. For this reason, a round of catch and breeding should be conducted before the squid is caught. The size of the fish is raised in ponds to balance the growth. This is one of the important measures to increase production.

4. Promote the wintering of squid. In autumn fishing, in addition to the sale of big fish, part of the adult fish can be moved into the deep pool over winter (nylon pond on the pond) to sell early spring fish; this will not only solve the problem of hard-to-sell sales during the high season but also extend the supply time of fresh fish. , and the fish price can be doubled, really killing two birds with one stone.

  1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .

2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.

3.Better protection with high titer and immune effVaricella Vaccineicacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75%  in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
