Problems solved by technology

Only wild fish in the Irtysh River system are distributed in the country. Perch is a carnivorous fish. In natural waters, only palatable live bait is eaten. Because the amount of palatable live bait is limited, the output is low and cannot be scaled. , the yield of artificial breeding is also very low

Embodiment Construction

[0016] The method of artificial domestication of wild perch is as follows:

[0017] 1. Breeding conditions:

[0018] Cement pool area selection 100-200m 2 , the water depth is 0.6-1m, the drainage is convenient, the drainage is equipped with anti-escape mesh, and there is oxygen increasing equipment. The area of ​​the pond is 3-5 mu, the water depth is more than 1.2m, and the thickness of the silt is not more than 20cm. The water source is sufficient, pollution-free, and there are good water inlet and drainage facilities. Before stocking, use quicklime medicine pond, the dosage is 30-50kg / mu, and each pond is equipped with an aerator.

[0019] 2. Water quality conditions

[0020] The breeding water meets the national aquaculture water quality standards. The optimum temperature for perch farming is 0-35°C, and the optimum growth water temperature is 18-25°C; the optimum pH value is 7.0-8.5; the dissolved oxygen content in the water is 5mg / L-8mg / L, the yield of perch in th...

Abstract

The invention provides an artificial domestication method for wild perches. The artificial domestication method for the wild perches comprises selection of cultivation conditions, selection of water quality conditions, throwing in and domestication of fish fry, feed selection feeding after changing of ponds and prevention of fish disease. The artificial domestication method for the wild perches has the advantages of enabling the per unit area yield of the wild perches to be more than 400 kg / mu, improving the yield of high quality wild perches by a large margin, effectively relieving an urgent requirement of the high quality wild perches in the local area and external areas and making contributions to the development of distinguished aquatic product industries in Sinkiang.

Description

technical field [0001] The invention relates to a method for artificially domesticating wild perch. Background technique [0002] Perca (Perca fluviatilis) belongs to the order Perciformes, the family Perch, and the genus Perca, also known as Wudaohei and colorful grouper. In my country, it is only produced in the Irtysh River system in Xinjiang. It is a rare and precious sub-cold freshwater fish. The fish has the characteristics of fast growth and strong disease resistance. It became one of the most productive economic fish in our region in the 1980s. Perch meat is rich and thin, delicious, with few intermuscular thorns, and has the characteristics of high protein and low fat. Only wild fish in the Irtysh River system are distributed in the country. Perch is a carnivorous fish. In natural waters, only palatable live bait is eaten. Because the amount of palatable live bait is limited, the output is low and cannot be scaled. , the artificial breeding yield is also very low...
