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.
