Embodiment 1

[0029] This embodiment is used to illustrate the method for cultivating S. sinensis provided by the present invention.

[0030] The iron cage specification that this embodiment adopts is 1m (length) * 0.4m (width) * 0.8m (height), and its surroundings and the bottom adopt the iron net that mesh is rectangular and the side length is 1cm * 1cm to build, and the top adopts solid The iron plate is constructed, and the opening is arranged on the top of the iron cage. The lower end of the iron cage is provided with a foam board with a height of 20 cm (arranged on the inner surface of the iron cage), and four fixing rings are arranged on the diagonal of the iron cage. , to reinforce the iron cage, the specific structural diagram is as follows figure 1 shown.

[0031] Choose a place with flat terrain and gentle water flow under the mangroves, install the iron cage when the tide is low, specifically, press the iron cage into the mud under the mangroves to a depth of 30cm, and then pla...

Abstract

The invention belongs to the field of aquaculture and discloses a method for adopting an iron cage for breeding bostrichthys sinensis under a mangrove forest. According to the method, the periphery and the bottom of the iron cage are all made of iron nets, the top of the iron cage is made of a solid iron plate, baffles are arranged at the lower ends of the periphery of the iron cage, and the height H of the iron cage is greater than the height h of each baffle, wherein the height h of each baffle is 10-30 cm. The method includes the steps of pushing the iron cage into silt under the mangrove forest, wherein the downward pushing depth of the iron cage is greater than the height h of each baffle and smaller than the height H of the iron cage, and during flood tide, seawater can at least inundate the area under the mangrove forest; then, putting bostrichthys sinensis into the iron cage for breeding. By adopting the provided method for breeding bostrichthys sinensis, the usage of baits canbe reduced, and the survival rate is increased. Additionally, since the provided method belongs to ecological breeding simulation, the taste and nutrient value of obtained bostrichthys sinensis are both identical to those of wild bostrichthys sinensis.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating Chinese snakeheads in iron cages under mangrove forests. Background technique [0002] Chinese snakehead is a fish belonging to the genus Wutang snakehead of the family Channaidae. It usually inhabits shallow seas, inner bays and estuary brackish waters. It is ferocious and feeds on small fish, shrimps and crabs, aquatic insects and shellfish. In the southern part of the Yellow Sea, the East China Sea, the South my country Sea, and the Sea of ​​Japan, it has strong vitality, wide adaptability, strong disease resistance, and fast growth. It is an excellent variety for artificial breeding. Channa sinensis is rich in nutrition, delicious in meat quality, and has the effect of accelerating wound healing. [0003] Due to the wide adaptability, strong disease resistance, and easy breeding of Chinese snakeheads, the cultivation of Chinese snakeheads along ...
