The stingray is a carnivorous fish. In the past, it was mainly used as a wild fish to survive in ponds and lakes. It uses small fish, shrimp, insects and various aquatic insect larvae (especially cockroaches and chironomid larvae) in water bodies. Shrimp, small mollusks and other aquatic invertebrates feed on food.
With the improvement of people's living standards and the adjustment of aquaculture structure, China has now adopted stingrays as high-quality fish for artificial breeding and large-scale breeding. However, the amount of natural food in water is limited, so the key to the development of large-scale breeding of yellow catfish is to solve the artificial domestication of bait. Now the two commonly used domestication methods are introduced as follows:
First, the domestication of animal foods The acquisition of small fish, shrimp, snail meat, etc. from the market is crushed into a paste. After water is poured around the pond, it induces feeding. Later, gradually reduce the spillage range and slowly lure the stingrays to feed on the bait station. After 7 days of domestication, the purpose of feeding animal feed at the bait station can be achieved regularly (2 times per day). However, using this method to raise yellow mullet costs a lot, and sometimes even outweigh the benefits. In general, the bait costs about 40%-60% of the total cost. The snail's bait coefficient is 60. Calculated at 1.2 yuan per kg of snail, the bait cost 36 yuan for every 1 kg of stingray, which is obviously higher than the market price of stingray in most regions. Therefore, it is necessary to develop domesticated bait for domestication. Only to reduce the cost of farming.
Second, with the bait domesticated According to the stingray as a carnivorous fish on the bait in the protein requirements of the higher proportion of the characteristics of the general design of the food formula is: Peruvian fish meal 45%, soybean meal 10%, 15% of the cake powder, sub-powder 15%, coarse grains 10%, yeast powder 2%, vegetable oil 1%, and attractant 2%. At the beginning of domestication, 10% formulated foods can be added to the original animal diets (fish, shrimp, and snail meat). After two days, the corresponding diets are added to 20% and the animal meat extracts are reduced by 10%. After 20 days of conversion, they can all be stopped. Animal fish food bait, use mixed food. This will not only guarantee the source, quantity, and quality of the bait, but also reduce the cost of the bait. It is easy to produce large-scale production and produce economies of scale.
