Embodiment Construction

[0030] The following examples further describe the present invention, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.

[0031] The steps of the present invention are as follows:

[0032] 1) Incubation of fertilized eggs: the hatching bucket adopts 0.5m 3 The FRP triangular hatching bucket is equipped with a water pipe full of drainage holes in the middle of the bucket, and the drainage hole is wrapped with 100-mesh nylon mesh. The nano-tracheal tube is fixed at the bottom of the drainage tube and connected to the trachea to prevent fish eggs from adhering to the Nylon mesh. The high-quality fertilized eggs after screening and separation are hatched by micro-flowing water, and the egg density is controlled at 300,000-400,000 eggs / m 3 , the amount of inflation is adjusted to drive the uniform distribution of fish eggs. Keep the hatch in the dark, the hatching...

Abstract

The invention relates to an industrialized fry cultivation method of oval pompano. The method comprises the steps of incubation, transfer of the fries, cultivation of fish larva and juvenile, fodder domestication and the like; according to the method, the fry cultivating processes are all conducted indoors, incubating and raising processes are not influenced by weather, and the yield of raised fries is greatly improved; the method can be used for carrying out directed screening to fed bait, and the fry survival rate in the stage is greatly improved; the requirement of fries on EPA and DHA is ensured, and the fry quality is guaranteed; in the process of industrialized cultivation, the temperature, salinity, dissolved oxygen and other factors in a fry cultivating water body are relatively stable, the aberration rate of the fries is effectively reduced, and the survival rate of the fries is improved; a fry separating sifter is utilized to periodically screen the fries, the self-injury of the fries is reduced, the survival rate of the fries is improved, and meanwhile, the homogeneity of the fries is guaranteed; the method has the advantages that the occupied area for industrialized cultivation of the fries is small, the water demand is less, the sewage discharge is less, and the influence on natural environment is small.

Description

technical field [0001] The invention relates to a method for cultivating seedlings, in particular to a method for cultivating industrialized seedlings of oval pomfret. Background technique [0002] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, is a high-quality edible seawater fish with tender meat, delicious taste, and no intermuscular spines. In the 1980s, Taiwan, China first broke through the breeding technology of oval pomfret, and in the early 1990s, it was introduced to the South China coast of the mainland for domestication. Because of its advantages of ingesting artificial compound feed, suitable for pond culture and deep-water anti-wind and wave cage culture, fast growth and short breeding cycle, the breeding industry of pomfret pomfret has developed rapidly in the past ten years, with an annual output of more than 100,000 tons , has become one of the most important mariculture fishes in the southern coast of my country, and has high economic ...
