Problems solved by technology

[0003] At present, artificial breeding of large yellow croakers is mainly carried out in cages. Due to the weak wind and wave resistance of the frame structure, it can only be limited to shallow sea areas in coastal harbors. A large number of fry, high breeding density, and a large amount of artificial bait, resulting in light color, fat body, greasy taste and low price

Embodiment 1

[0028] Step 1. Place four buoys 1 in the deep water area. The buoys 1 are fixedly connected with the fixed piles through the steel cables 2. The buoys 1 are connected with the flexible nets 3 to form a rectangular closed area, and are reserved for fishing. The opening for the fish boat to enter and exit, the net clothing 3 makes the net clothing open to form a net wall through the fixed float 4 at the upper end and the fixed net pendant 5 at the lower end, and the float 4 is a cylindrical foam float with a diameter of 60cm and a length of 80cm. The lower end of the anchor chain is connected to the anchor chain, and the plumb weight 5a for increasing the weight is hung on the anchor chain. The anchor chain sinks into the mud on the seabed under the action of gravity. Sinking piles 6 are arranged, and the net clothes 3 are connected and matched with the sinking piles 6 through connecting ropes 7. The height of the net clothes 3 is 1.2 times higher than the highest tide level of s...

[0034] Step 1. Place four buoys 1 in the deep water area. The buoys 1 are fixedly connected with the fixed piles through the steel cables 2. The buoys 1 are connected with the flexible nets 3 to form a rectangular closed area, and are reserved for fishing. The opening for the fish boat to enter and exit, the net clothing 3 makes the net clothing open to form a net wall through the fixed float 4 at the upper end and the fixed net pendant 5 at the lower end, and the float 4 is a cylindrical foam float with a diameter of 80cm and a length of 120cm. The lower end of the anchor chain is connected to the anchor chain, and the plumb weight 5a for increasing the weight is hung on the anchor chain. The anchor chain sinks into the mud on the seabed under the action of gravity. Sinking piles 6 are arranged, and the net clothes 3 are connected and cooperated with the sinking piles 6 through connecting ropes 7. The height of the net clothes 3 is 1.5 times higher than the highest tide level ...

Abstract

The invention discloses a method for large-scale breeding of large yellow croakers in the open deepwater sea area. The method comprises the steps as follows: laying a breeding device; putting adult fishes into the breeding device; daily monitoring; catching the finished fishes; and recovering the breeding device. A closed area is defined through a netting, the position of the netting is kept relatively stable by a buoy, and the artificially bred large yellow croakers are wildly acclimatized in the deepwater sea area by making full use of the natural resources in the deepwater sea area, so that the meat quality and the mouth feel of the artificially bred large yellow croakers are closer to those of the wild large yellow croakers, and further the economic value of the artificially bred large yellow croakers is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating large yellow croakers, in particular to a large-scale method for cultivating large yellow croakers in deep waters in open seas. Background technique [0002] Large yellow croaker, which belongs to the family Stoaceae and the genus Yellow croaker, is commonly known as yellow croaker and yellow croaker. Due to overfishing in the early 1970s, the resources were severely damaged and could not be restored. In the 1980s, the Ningde area of ​​Fujian successfully broke through the artificial breeding and breeding technology of large yellow croaker, which rapidly expanded the industrial scale of artificial breeding of large yellow croaker. At present, large yellow croaker has become the largest seawater fish in China and one of the eight advantageous export aquaculture products, with remarkable economic benefits. [0003] At present, artificial breeding of l...
