Embodiment Construction
[0014] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.
[0015] A kind of fast feed domestication method of California perch, comprises the following steps:
[0016] Step 1: Sprinkle the zooplankton cultivated with fertilizer and water into the pond, and feed the perch fry for 20-25 days.
[0017] Step 2: When the fry grow to 2-3 cm, they can start domestication. On the first day, 70% surimi and 30% perch feed are mixed and stirred for feeding, and on the second day, 50% surimi and 50% perch feed are mixed and stirred. Feed, stop eating on the third day, and all use perch feed for feeding on the fourth day. The perch feed used is 0# perch compound feed, and the above ratios are mass ratios.
[0018] The feeding method adopts the method of timing and throwing. Feeding is 3-4 times a day, and the...

Abstract
The invention relates to the technical field of aquaculture, in particular to a micropterus salmoides fast feed domestication method which mainly includes the steps of firstly, spreading fertilizer water cultured floating animals into a pond and feeding micropterus salmoides fries for 20-25 days; secondly, starting domestication when the fries grow to 2-3 centimeters, mixing and stirring 70% of minced fillets and 30% of micropterus salmoides feed to perform feeding in the first day, mixing and stirring 50% of minced fillets and 50% of micropterus salmoides feed to perform feeding in the secondday, stopping feeding in the third day and totally using the micropterus salmoides feed for feeding in the fourth day; third, performing water quality management. The ratio is mass ratio. By the culture domestication method, micropterus salmoides culture is simpler and more convenient, the micropterus salmoides fries are fast in feeding and low in dog-eat-dog rate, finally, the labor intensity ofworkers is greatly reduced, labor efficiency and fry survival rate are increased, and water quality pollution is reduced.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fast feed domestication method for California perch. Background technique [0002] California perch, also known as largemouth bass, belongs to Perciformes, Perciformes, Sunfish family, and Black Perch, and is a freshwater carnivorous fish. Native to North America, it was introduced from abroad by Taiwan, China in the late 1970s, and was successfully artificially propagated in 1983, and was introduced to Guangdong Province from Taiwan, China in the same year. Because of its strong adaptability, fast growth, short breeding cycle, easy to catch, etc., coupled with delicious and tender meat, no intermuscular spines, etc., it is very popular among farmers and consumers, and has become one of the important freshwater aquaculture species in my country. [0003] In the breeding process, feeding chilled fish not only has a heavy workload for workers, but also may bring in pathogens...
