Liza haematocheila seawater pond circulating water fry breeding method

Abstract

The invention discloses a Liza haematocheila seawater pond circulating water fry breeding method, and relates to the technical field of fry breeding. The breeding method comprises S1, conducting construction of a net cage circulating water fry breeding facility and S2, performing net cage circulating water fry breeding management, wherein the S1 is further subdivided into a, building of a fry breeding net cage; b, performing installing of a submersible pump; c, light luring living organism baits; and d, performing installing of an inflation facility; the S2 is subdivided into e, performing pond equipment work; f, preparing living rotifers, feed and Liza haematocheila fertilized eggs: purchasing the living rotifers and the feed; g, performing fry hatching; h, performing fry period management; i, performing young fish period management and j, performing juvenile fish period management, wherein the sub-steps h, i and j all comprise day age and breeding density control, feed feeding and net cage replacement or cleaning. A fry breeding technical mode is provided according to the breeding characteristics and living habits of the Liza haematocheila fry. The method has the advantages of high density and strong controllability of a cement pond mode, low cost of a pond mode, easiness in popularization and the like.

Description

technical field [0001] The invention relates to the technical field of fish fry cultivation, in particular to a method for raising seedlings of yellow-eyed mullet in a seawater pond with circulating water. Background technique [0002] "Yellow-eyed mullet" is a common name in Wenzhou, and its scientific name is Liza haematocheila, which belongs to Mugiliformes, Mugilidae, and genus Liza. It is a widespread fish in the Northwest Pacific Ocean. It is mainly distributed in the coasts of China, the Korean Peninsula and the coast of Japan. It inhabits shallow seas near the coast with a water depth of no more than 10m. It is also distributed in freshwater areas of estuaries. It does not migrate long distances. An endemic fish. Its suitable temperature range is -0.7~35℃, and the optimum temperature is 12~25℃; its suitable salt range is 0~30℃, suitable for living and growing in brackish water or even pure fresh water. It is an important economic fish in the coast of my country. In...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for cultivating seedlings of yellow-eyed mullet in a seawater pond with circulating water, which solves the conventional indoor cement pond seedling raising technology mode of seawater fish at present, which has the advantages of high density and strong controllability, but has high requirements for facilities , the cost of raising seedlings is also high, while the seawater fish pond breeding technology model has the advantages of low cost and easy promotion, but the seedling effect is unstable and the density is low.
