Embodiment Construction

[0021] The following are examples of the present invention, but the technical solution of the present invention is not limited to the examples listed below, and also includes any combination of specific implementation methods.

[0022] Breeding Example

[0023] (1) Seedling cultivation: The eyed salmon eggs of autumn salmon were introduced from the Heilongjiang Fisheries Research Institute of the Chinese Academy of Fishery Sciences, and hatched in the nursery workshop of the Oriental Ocean Shanhai Branch. Transport 3,600 unsalinated fish fry to the culture base of Dongfang Ocean Development Zone for seawater stage culture. The culture is divided into thirteen control groups A-M, with 200 fish in each group. See Table 2 for the average weight. into different circulating water systems for cultivation.

[0024] (2) Mariculture:

[0025] Breeding 5g-35g (group A-E) seedlings are cultured by seawater flowing water. The breeding pond is a square cement pond with four corners in an...

Abstract

The invention discloses a mariculture method for oncorhynchus keta. The mariculture method for oncorhynchus keta is implemented mainly from four aspects of culture equipment, feedstuff feeding, water quality requirements, daily management and the like. Complete artificial mariculture for oncorhynchus keta is achieved for the first time in China by means of unique culture technology and culture conditions. The method comprises the following advantages that it can be ensured that oncorhynchus keta is protected against influences of severe natural environment and various natural enemies in the growth process, the growth speed is high, and the survival rate is high; 2, oncorhynchus keta can be harvested in any growth stage, the meat quality is ensured, and meanwhile products with different specifications are provided for the market; and a foundation is laid for achieving complete artificial breeding of oncorhynchus keta. By integrating the advantages, the method has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to a seawater culture method for autumn salmon, and belongs to the field of aquatic product culture. Background technique [0002] Autumn salmon (Oncorhynchus keta), also known as chook salmon and salmon, belongs to the order Salmoniformes, the family Salmonidae, and the genus Oncorhynchus. It is a famous rare and precious cold-water fish in my country. It is mainly distributed on the east and west banks of the North Pacific Ocean.
