Sebastodes fuscescens parent fish warming cultivation and childbearing method

Abstract

The invention discloses a sebastodes fuscescens parent fish warming cultivation and childbearing method which comprises the following steps of: 1) selection of parent fish; 2) selection of farming facilities; 3) warming cultivation of the parent fish; and 4) childbearing. The method disclosed by the invention makes full use of the water quality conditions of the natural water body, the farming operation is simple and convenient, and the energy consumption is reduced. By adjusting the farming water temperature, the childbearing period of the sebastodes fuscescens parent fish is reduced by at least 20 days than the traditional method. Moreover, the parent fish obtained by the method has high quality, the parent fish can be recycled, and the normal childbearing rate can exceed 95%, thus the wild resources are protected while laying a foundation for obtaining high-quality child fish. The child fish obtained by the method is healthy with high quality and high survival rate, and large-specification fingerlings can be supplied in batches in advance; and moreover, by artificially controlling the environmental factor of indoor farming, the indoor artificial propagation method of sebastodes fuscescens is innovated, so that the parent fish gives birth in advance and an effective method is provided for obtaining large-scale fingerlings in advance.

Description

technical field [0001] The invention relates to a method for raising the temperature of broodstock black anchovy and giving birth. Background technique [0002] Black scorpion (Sebastes schlegeli), also known as Xu's flat scorpion, belongs to Scorpiomorpha, Scorpionidae, and Scorpion genus. It is a cold-temperate offshore bottom fish. It is oviparous and has a small migration range. It is widely distributed in the Yellow Sea and the East China Sea. It has the advantages of wide temperature range, strong adaptability, and less disease. It is an ideal species for artificial fish reefs for resource multiplication and cage culture, and has become an important cultured species along the coast of northern China. However, due to the special breeding habits of black carp, the breeding technology level of its seedlings is not high, far below the breeding technology level of other cultured fish. Although the artificial nursery technology of black carp has been broken through, the exi...

This breeding method destroys wild resources to a certain extent, and the quality of the larvae obtained is not high, and the survival rate is low

[0003] At present, the production process of black carp seed depends on natural resources to a high degree, and there is no report on the whole process of broodstock breeding. Most of the larvae are obtained in May, which makes the acquisition of large-scale seed late, and the actual production cannot meet the needs of cages. The demand for large-scale seedlings in farming
