Abstract

The invention relates to a wild-Cottus-poecilopus domestication method and belongs to the technical field aquaculture. The method includes water source selection, domestication condition setting, domestication method selection, fish disease control and the like. The domestication survival rate of the method is 85.9%, the artificial propagation of Cottus poecilopus becomes possible, a foundation islaid for complete artificial propagation and large-scale propagation, and the method is of greatly significance to Cottus poecilopus species protection and also provides technical support for providing precious cultivation varieties for cold water fish industry.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for artificial domestication of wild variegated sculpin. Background technique [0002] The variegated sculptus belongs to the genus Sculptus of the Sculptidae suborder Sculptidae, and is only distributed in Heilongjiang, Songhua River, Wusuli River, Suifen River, Tumen River, Yalu River, Hunhe River, a tributary of the Liaohe River in China. Taizi River, Biliu River in Liaodong Peninsula, etc., are found abroad in northern North Korea, Russian Far East and Nordic countries. They are sexually mature at the second age and feed on aquatic insects and their larvae, as well as small fish and shrimp. Variegated sculpin is a small and rare fish in cold water. Its outstanding features are: (1) The meat is tender and garlic-shaped, with good taste and high nutritional value. (2) Living in a stream with no pollution and clear water quality, the living environment ...
