Problems solved by technology

[0003] At present, there is no large-scale breeding of marine rainbow trout in my country, and its seed cultivation is still in the exploratory stage. Compared with traditional seedling raising methods, industrial seedling breeding can efficiently produce healthy seedlings with limited natural resources

Embodiment Construction

[0020] Describe in detail below in conjunction with embodiment, present embodiment is the seedling raising test that applicant carries out in Muping culture base, the industrialized seedling raising method of marine rainbow trout of the present invention, comprises the steps:

[0021] (1) Incubation

[0022] In the salmon hatching workshop of the applicant's Muping breeding base, the hatching of marine rainbow trout eggs is carried out. Incubation adopts the fresh water flow method. The aquaculture water passes through the refrigerator, spraying device, and absorbent cotton in order to control the water temperature, remove excess gas in the groundwater, and filter large suspended particles. The water quality after treatment meets the fishery water quality standard (GB11607-89). The cabinet-type incubator used for incubation is manufactured by ALVESTAD company in Norway. The incubator has 8 layers, each layer is composed of 2 hatching tanks, and the size is 60cm×60cm×60cm. 6L...

Abstract

The invention discloses an industrialized fry breeding method for marine oncorhynchus mykiss. The method comprises steps as follows: (1), hatching: eyed eggs are hatched in an indoor fresh water flowing manner, and a hatching room keeps dark; (2), breeding of fish larvae and juveniles: the fish larvae and juveniles are bred in the indoor fresh water flowing manner, the water temperature is kept in a range from 10 DEG C to 14 DEG C, the new water addition amount of a single pool is 10-15 L / min / 10,000 fish larvae and juveniles, and the breeding density in the water flowing mode does not exceed 15 kg / m<3>; (3), fry breeding: the marine oncorhynchus mykiss fries are bred by adopting indoor closed circulating fresh water, the water temperature is kept in a range from 14 DEG C to 18 DEG C, the water circulating amount of a circulating water breeding pool is 15-25 times / day / pool, the illumination intensity is kept in 800-1,000 lux, and the 24 hours of illumination intensity is kept. The fry breeding process of the marine oncorhynchus mykiss is performed indoors and is not influenced by weather, year-round production can be realized, the water quality condition is stable and controllable, the survival rate of the bred fries is high, and high-density large-scale breeding can be realized.

Description

technical field [0001] The invention relates to an industrial seedling raising method for marine rainbow trout, belonging to the technical field of aquatic seedling raising. Background technique [0002] Rainbow trout (Oncorhynchus mykiss) belongs to Salmoniformes, Salmonidae, Pacific Salmon, and is the most widely cultivated rare cold-water fish in the world. There are two types of rainbow trout: land-sealed type (living in lakes and rivers all their lives) and sea-falling type (a strain that can grow in the sea, called steelhead trout). After years of research, Denmark's AquaSearch company has developed a high-salt-tolerant all-female marine rainbow trout. Compared with the domestic traditionally cultured rainbow trout, this strain has fast growth, low feed coefficient, strong disease resistance, and high breeding economic benefits. [0003] At present, there is no large-scale breeding of marine rainbow trout in my country, and its seed cultivation is still in the explor...
