Embodiment 1

[0025] An artificial breeding method for reducing the feed coefficient of light-colored croaker and improving the swim bladder quality of light-colored croaker, comprising the following breeding environment: salinity 11ppt; water temperature 19-23°C; pH 7.1-7.6; ammonia nitrogen less than 0.06mg / L; dissolved oxygen greater than 6.0mg / L. The method of reducing the salinity of the culture is as follows: from the natural seawater salinity (29ppt), the salinity is reduced by 3-5ppt every day, and the salinity is 11ppt after 4 days.

Embodiment 2

[0027] An artificial breeding method for reducing the feed coefficient of light-colored croaker and improving the quality of the swim bladder of light-colored croaker, comprising the following breeding environment: salinity 8ppt; water temperature 19-23°C; pH 7.1-7.6; ammonia nitrogen less than 0.06mg / L ; Dissolved oxygen is greater than 6.0mg / L. The method of reducing the salinity of the culture is as follows: drop 3-5ppt from the natural seawater salinity (29ppt) every day, and the salinity will be 8ppt after 5 days.

Embodiment 3

[0029] An artificial breeding method for reducing the feed coefficient of light-colored croaker and improving the quality of the swim bladder of light-colored croaker, comprising the following breeding environment: salinity 6ppt; water temperature 19-23°C; pH 7.1-7.6; ammonia nitrogen less than 0.06mg / L ; Dissolved oxygen is greater than 6.0mg / L. The method of reducing the salinity of the culture is: from the natural seawater salinity (29ppt) to drop 3-5ppt every day, and the salinity will be 8ppt after 5 days; then reduce 2ppt every day, and the salinity will be 6ppt after a total of 6 days.

Abstract

The invention discloses a breeding method for decreasing the feed coefficient of light-colored nibea albiflora and improving the quality of swimming bladders. According to the method, the salinity ofan original living water environment of light-colored nibea albiflora is taken as the initial salinity of the breeding water environment, the salinity of the breeding water environment is gradually lowered, the final salinity of the culture water environment is finally formed, and breeding of light-colored nibea albiflora continues in the breeding water environment with the final salinity. The breeding method can decrease the feeding amount of feed and increase the content of crude proteins and collagen in the swimming bladders while not influencing the growth of light-colored nibea albiflora,so that the feed coefficient of light-colored nibea albiflora is decreased, and the quality of the swimming bladders of light-colored nibea albiflora is improved.

Description

technical field [0001] The invention relates to a breeding method for reducing the feed coefficient of light-colored meager and improving the quality of the swim bladder, and belongs to the field of fish artificial breeding. Background technique [0002] At present, high-density intensive breeding is generally adopted in artificial fish breeding, and the production cost is mainly the cost of feed. How to reduce the cost of feed is the key to increasing the benefits of artificial fish farming. The level of feed cost is determined by the level of feed price and feed coefficient. Under the situation that there is not much room for the price reduction of feed, how to change the breeding method, improve the utilization rate of feed, and reduce the feed coefficient are the key factors to reduce the cost of feed. Salinity represents the total concentration of various salts contained in the water body, is one of the most important abiotic factors affecting the growth and survival ...
