Yellow plate crucian carp

Yellow plate crucian carp, the scientific name triangle carp, is a wild famous and excellent economic fish in rivers. Tender meat and delicious taste, the price of yellow plate crucian carp weighing more than 400 grams is as high as 80m / kg, which has a very high economic value. In recent years, due to the deterioration of river ecological environment and excessive fishing, the wild resources of yellow plate crucian carp are becoming more and more depleted. In order to develop and protect this precious natural resource, Shaoguan Fisheries Research Institute has carried out artificial culture and reproduction experiments of yellow plate crucian carp since 2001 and achieved success.

1. Pond conditions: the pond area should be 8 mu / mouth, with sand and gravel sediment, less silt, good water quality, convenient entry and drainage, and a water depth of 1.5 muri 2 meters. If possible, it should also be equipped with oxygen facilities.

Second, the stocking mode: the mixed culture mode based on unisexual tilapia and grass carp was adopted. Desilting and disinfecting before stocking, 100 yellow crucian carp fry with a specification of about 5 cm were released at the end of March and the beginning of April, and 10 days later, unisexual tilapia and large grass carp were released according to conventional culture methods, and matched with an appropriate amount of silver carp and bighead carp, generally do not or less cast carp, crucian carp, mud carp and other bottom fish.

3. Feed feeding: it is the same as the pond feeding method of tilapia, mainly feeding tilapia pellet feed, which accounts for about 3% of the total weight of eating fish, so it is not necessary to feed separately for yellow plate crucian carp.

Fourth, daily management: daily focus on water quality management. As the yellow crucian carp is a wild fish in rivers, the requirements for water quality and dissolved oxygen are slightly higher, so the daily management should pay attention to the pond water quality should not be too fertile, often flush with new water to keep the water fresh and sufficient dissolved oxygen. In terms of diseases, because the yellow plate crucian carp is a new breeding variety, the breeding time is short and the breeding quantity is small, so as long as we pay attention to the regulation and control of water quality, there are generally no serious diseases.

Fifth, culture effect: yellow plate crucian carp is omnivorous fish, in the pond environment, mainly feed on aquatic insects and artificial compound feed. Under the condition of no or less competition from other bottom fish, yellow plate crucian carp grows rapidly and can reach the market specification of more than 500 grams per tail after one year of culture. Calculated according to the survival rate of 80%, the annual harvest of yellow plate crucian carp can be 40 kg / mu, and according to the current purchase price of 80 murmur100 yuan / kg, the income of single yellow plate crucian carp can reach 3000 murmur4000 yuan / mu, the breeding profit is huge, and the breeding effect is remarkable.
