Bostrychus sinensis feeding method and acoustic domestication feeding system thereof

Abstract

The invention discloses a bostrychus sinensis feeding method and an acoustic domestication feeding system thereof. The method is characterized in that excellent diatom is inoculated after water changing, chaetoceros is selected as the diatom, the feed feeding is decreased progressively according to the levels of 8%, 7%, 6%, 5% and 4% of the total weight of fish, each level is fed for 3 days, 15 days serve as a period, after 15 days, 100% water change is carried out, a fishing pond is cleaned, weighing is carried out, the above operation is repeated, an acoustic domestication feeding system isadopted for feeding during feeding, the acoustic domestication feeding system comprises a support frame, and a hydrophone and a camera which are positioned in a culture pond, four feeding machines, aloudspeaker and a controller are arranged on the support frame, and the feeding machines, the loudspeaker, the hydrophone and the camera are all electrically connected with the controller. The methodhas the functions of improving the feeding efficiency, reducing the feed loss, adjusting the pH value of the water body and inhibiting the growth of bacteria, so that the fatality rate of the bostrychus sinensis is reduced, and the survival rate of the bostrychus sinensis is increased.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a feeding method for Chinese snakehead and an acoustic acclimation feeding system thereof. Background technique [0002] Chinese snakeheads belong to Osteichthyes, Perciformes, Gobies suborders, and Channaidae, commonly known as "earth fish", and are a kind of warm-water shallow sea fish. It is distributed in salt water areas such as coastal areas, estuaries, and harbors in southern my country, and likes to inhabit sandy mud bottom or reef areas. Channa sinensis is a rare marine fish with delicate meat, delicious taste, rich nutrition and high economic value. In the process of cultivating Channa sinensis, the acidification of seawater will lead to the growth and reproduction of bacteria. Harmful bacteria such as Vibrio verticillium and Vibrio parahaemolyticus can easily cause skin ulcers of Channa sinensis, which is difficult to treat, highly contagious, and easy to relaps...

AI Technical Summary

Problems solved by technology

In the process of cultivating Channa sinensis, the acidification of seawater will lead to the growth and reproduction of bacteria. Harmful bacteria such as Vibrio verticillium and Vibrio parahaemolyticus can easily cause skin ulcers of Channa sinensis, which is difficult to treat, highly contagious, and easy to relapse. Features, when the existing feeding method is used for feeding, because the fish are distributed everywhere in the fish pond, the feed will be put into the fish pond, but this will cause a lot of waste of feed, and the excess feed will easily lead to bacteria in the seawater Obtaining a large number of nutrients and multiplying, and acidic feed will increase the acidification of seawater and provide an environment for bacterial growth, resulting in a decrease in the survival rate of Chinese snakehead
