Problems solved by technology

[0004] Salmon are usually hatched and larvae grown in fresh water, and need to be domesticated in seawater before being transferred into seawater. In CN106577369, a method for off-shore breeding of large-scale salmon and trout in temperate seas mentions mariculture in the cold water mass of the Yellow Sea. However, it is mainly aimed at the overall farming method, and does not have any inspiration for how to domesticate seawater.
At present, the seawater domestication of salmon commonly used in my country is mostly the domestication method from 0 degree fresh water to 30 degree sea water step by step, but this method has a long domestication period and low survival rate

[0019] Embodiment 1 Salmon Seawater Domestication Technology Comparative Test

[0020] 1. Experimental methods and materials

[0021] 1.1 Experimental materials

[0022] 1.1.1 Fish species: It is best to purchase salmon with a domestication specification of 400-500 grams from farmers. 3000 tails in the domestication experiment group and 3000 tails in the control group were carried out simultaneously.

[0023] 1.1.2 Equipment: Check water pumps, air pumps, microfilters, lines, switches, and have anti-leakage protection. Check that the inflatable pan and pipeline are in good condition.

[0024] 1.1.3 Tools: Prepare electronic scales, fishing nets, buckets, and brushes.

[0025] 1.2 Experimental method

[0026] 1.2.1 Experimental grouping

[0027] The acclimatization of the experimental group started from 15°C salt water to 30°C salt water step by step, and was divided into two stages according to the domestication technical route, as shown in Table 1.

Abstract

The invention discloses a salmon seawater acclimation method. According to the method, the acclimation transition stage of salmon from freshwater to seawater is standardized, an existing acclimation method for 0-degree freshwater to 30-degree seawater step by step is changed, fingerlings of the specification being 400 g or larger are selected, the technical route for beginning acclimation from 15-degree saline water is adopted, the good adaptability of salmon can be achieved only within two weeks, the survival rate can reach 99% or above, the acclimation period is effectively shortened, and the cultivation efficiency is improved.

Description

technical field [0001] The invention relates to a seawater domestication method of salmon, which belongs to the field of aquaculture. Background technique [0002] Salmon, also known as salmon, salmon, and Salmon, belongs to the bony fish class, salmoniformes, and salmon genus. It is mainly distributed in the waters at the junction of the Atlantic Ocean, the Pacific Ocean, and the Arctic Ocean. It is a highly migratory fish in cold water. The gourmet industry is known as the "Emperor of the Ice Sea". Studies have shown that both tuna and salmon are delicious, nutritious, and rich in biologically active substances such as EPA and DHA. There are more than 30 species with commercial value, and the two most common types of trout (salmon trout, golden trout) and 4 types of salmon (Pacific salmon, Atlantic salmon, arctic char, coho). Many salmon are fish that can be cultured in both freshwater and seawater. Freshwater farming is common in my country. In 2014, the production of f...
