Problems solved by technology

The commercial culture of mandarin fish has always been carried out by feeding live bait, and mandarin fish fry will feed on other species of fish when they emerge from the film. Therefore, the survival rate of seedlings is low under natural conditions. Two restrictive factors for the rapid and large-scale development of production

Abstract

The invention discloses a method for large-scale breeding of large-standard mandarin fish fingerling. The method comprises the steps of 1 pool selection, 2 pool cleaning and disinfection, 3 forage fish breeding, 4 mandarin fish fry and large-scale fingerling breeding, 5 released density determination, 6 forage fish feeding, 7 water quality management and 8 disease control. The method is easy and convenient to operate, simple in device, easy to manage and high in fingerling survival rate. The method takes the lead in successfully breaking through a key of a large-scale mandarin fish fingerling technology at home and abroad, natural bait breeding through fertilizer controlled-release bags and manual bait domestication is used in cooperation for feeding are creatively and successfully achieved in the aspects of fingerling breeding, bait feeding and the like, the blank of domestic large-scale mandarin fish fingerling breeding in a pool is filled, the survival rate of the fingerling is over 80%, the water quality of the pool is kept good, most effective practical measures and means are created for thorough development of mandarin fish serving as a famous excellent breeding breed, and the method has the great social benefit and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating large-scale mandarin fish fingerlings on a large scale. Background technique [0002] Siniperca, also known as mandarin fish (Sinipercachuatsi), is a rare freshwater fish belonging to the suborder Perciformes. Because of its fast growth rate and high nutritional value, it has become more and more popular among consumers, and has become the main species in China's famous and high-quality aquaculture. The demand of market consumers is in short supply, and the market price is constantly increasing. Climbing, reaching 70-80 yuan per kilogram. But this kind of fish has a peculiar feeding habit, and feeds on live fish and shrimps throughout its life. Usually, it absolutely refuses to eat dead bait or compound feed. This phenomenon is very rare in fish (Liang Xufang, 2002). The commercial culture of mandarin fish has always been carried out by ...
