Problems solved by technology

I missed this stage of domestication. If I don’t domesticate at this stage, I will eat wild fish as soon as I start eating, and it will be difficult to eat compound feed for artificial compound feed breeding in the later stage. Due to the limitation of technical level in this stage of domestication from fry to fish species, it is difficult to The survival rate is greatly reduced, which has become a bottleneck problem in the breeding process of snakehead

Abstract

The invention relates to a snakehead seedling expandable compound feed and a method for comprehensively feeding snakehead seedlings by using the same. The snakehead seedling expandable compound feed has buoyancy rate of 100 percent, floats in water when fed to the snakehead seedlings, is more soft and elastic after entering the water, is closer to the meat in the aspect of physical character, hasgood body color and mouth feel as well as special taste and better water stability, and solves the difficulty of food-transferring domestication. Multiple vitamins and multiple mineral elements premix prepared in the feed is set according to the demands of the snakehead seedlings, has the functions of promoting the growth and improving the survival rate, is suitable for the nutrition demands of the snakehead seedlings, has low feed coefficient, ensures rapid snakehead growth, expands the matched feed, avoids the loss of nutrients and the pollution to water, improves the feed utilization and reduces the generation rate of diseases, thereby lowering the feeding cost, and improving the feeding benefit. The snakehead can be fed together with the chub and the bighead to gain higher economic benefit and is suitable for the northeast area of China. The meat of commercial snakehead has high quality and best mouth feel.

Description

technical field [0001] The invention belongs to the field of aquaculture, and specifically relates to an expanded compound feed for snakehead seedlings and a feeding method. Background technique [0002] Channa argus (Channa argus) belongs to Perciformes, Climbing perciformes, Channaidae, Channa genus. Commonly known as mullet (North and East China), talented fish (Hunan and Hubei), raw fish (Guangdong, Hong Kong), black stick (Southwest), also known as black fish, snakehead fish, black fish stick, grouper and grass snakehead, etc. In the anoxic water body, it can use the auxiliary respirator in the upper cavity of the gills to breathe with its head tilted out of the water from time to time, and a certain amount of gas is stored in the depression above the throat; it can survive for a long time after leaving the water body , It is not easy to die during transportation and sales, can survive for a long time, and the cost is low; and the body is not easy to rot and deteriorat...
