Problems solved by technology

Because this kind of large fish has a strong sense of territory, fighting and attacking each other is a common phenomenon during the cultivation process. When a cage of corrugated lip fish is cultured in sea cages, the huge loss often comes from killing each other. After one process of breeding, the survival rate is often less than 10%

Embodiment 1

[0018] From December, 2006 to May, 2008, we adopted the technology of the present invention to cultivate the squid in Xincun Port, Lingshui County, Hainan, and obtained a 90% survival rate (the other 10% loss was due to the impact of the typhoon). Methods as below:

[0019] 1. Cut off the incisors: Lift the selected corrugated lip fish out of the water, and use small wire-cutting scissors to align the upper and lower jaws with a total of four incisors and cut them off from the roots to make the roots even. The corrugated lip fish that have had their front teeth cut off can be kept together for a period of time. When signs of fighting with each other are found, they should be kept separately in time.

[0020] 2. Scattered breeding, one cage and one tail

[0021] According to the size of fish body, make different size breeding net cages (fish cages), raise fish separately, raise separately in the net cage, and each net cage carries out classification number. The length of time...

Embodiment 2

[0026] From May 2008 to May 2009, we adopted the technology of the present invention to culture the chrysalis in Xincun Port, Lingshui County, Hainan, and obtained a 100% survival rate during the experiment. Methods as below:

[0027] 1. Cut off the incisors: Lift the selected corrugated lip fish out of the water, and use small wire-cutting scissors to align the upper and lower jaws with a total of four incisors and cut them off from the roots to make the roots even. The corrugated lip fish that have had their front teeth cut off can be kept together for a period of time. When signs of fighting with each other are found, they should be kept separately in time.

[0028] 2. Scattered breeding, one cage and one tail

[0029] According to the size of the fish body, different sizes of breeding net cages are made, and the fish are raised separately and kept in the net cages separately, and each net cage is classified and numbered. The length of time the rearing will be based on th...

Abstract

The invention discloses an offshore net cage cultivation technology of cheilinus undulates. The offshore net cage cultivation technology is characterized in that: before the cultivation is started, for the introduced large-sized cheilinus undulates, incisor teeth are sheared off first, and thus the aggressiveness among the cheilinus undulates is reduced; the cheilinus undulates can be centrally fed for a period of time according to the condition of fishes; and when mutual aggressive behavior is found, the timely separated cultivation is required and one fish is fed in one cage, which is important guarantee for improving the cultivation survival rate. Aiming at a large amount of attaching organisms in an Atami area, the cultivation net cage is required to be timely cleaned so as to avoid the damage of the attaching organisms to the fishes. By adopting three technologies, huge loss caused by mutual killing among the fishes can be avoided and the cultivation benefit and the protection of resources are improved.

Description

technical field [0001] The invention relates to a breeding technology of a rare marine species of rippling fish, belongs to the field of fish farming, and is applied to the protection of marine endangered species, resource multiplication and aquaculture. Background technique [0002] Humphead wrasse (Cheilinus undulates Rüppell, 1835), commonly known as Su Mei, English name: Humphead wrasse, Napoleon fish. It was listed as the second among the top ten endangered species by the "World Conservation Union (IUCN) Red Book" in 2004, and was also included in the "Washington Convention" (CITES) Appendix II species at the end of the same year. The fish has become one of the iconic species of coral reef waters. [0003] Because of its delicious taste and beautiful shape, corrugated lip fish has always been the most valuable fish in the seafood market. Whether it is aquaculture or ecological protection, this fish has great value. [0004] In the process of artificial breeding, it i...
