AI Technical Summary
During the artificial breeding process of rippled bream, the survival rate of fry is low when hatching, especially due to lack of swimming ability, which leads to lack of oxygen at the bottom or the influence of inflation bubbles, resulting in the hatching rate being reduced to 30-60%, and most of the fry can only survive for about a week.
A device was designed that includes a reflux purification tank, an incubation tank, and multiple incubation containers. The incubation containers are in the shape of a hollow bullet and are equipped with a 60-mesh screening net and a water pump circulation system. Through water exchange and biological filtration, the water quality is maintained stable to avoid damage caused by bubbles. Biochemical cotton and denitrifying bacteria are used to decompose soluble organic matter, forming a water quality cycle.
The hatching survival rate of ripple lip fish is improved, the water flow dead corners and bubble damage in traditional hatching methods are avoided, the water quality is kept fresh, and the survival ability of the fry is enhanced.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of artificial breeding of undulating lip fish, in particular to an artificial hatching device for undulating lip fish. Background Art
[0002] The wavy lipper, a member of the family Wrasseniidae, order Perciformes, and genus Gnaphalidae, is a highly prized tropical marine fish. Due to its high economic value and high market demand, overfishing has led to a sharp decline in its wild population. In 2004, the World Wildlife Fund published a list of 10 endangered species worldwide, with the wavy lipper ranked second. That same year, it was designated vulnerable by the IUCN. In January 2021, wild populations of the wavy lipper were listed as Class II protected species (wild populations only) on my country's National List of Key Protected Wildlife (No. 3 of 2021), and fishing of wild populations is prohibited.
[0003] Fry fish often live in shallow waters inside the reef, while adults often appear in deeper waters outside the reef area. They mainly feed on mollusks, fish, sea urchins, crustaceans and other invertebrates.
[0004] Because the wavy lipper is domesticated from its wild parent, artificial breeding technology has yet to achieve large-scale breakthroughs. Artificial fry rearing is difficult, with low survival rates and a shortage of seedlings. Consequently, large-scale artificial breeding of the wavy lipper has not yet been achieved. However, during artificial fry rearing, it was discovered that the larvae of the wavy lipper are slender and lack swimming ability. During hatching, they tend to sink to the bottom due to lack of oxygen or the effects of air bubbles. This reduces the hatching rate to 30-60%, and most larvae only survive for about a week. If this problem of larval fry sinking to the bottom during hatching is not resolved, it will be impossible to improve the survival rate of artificial fry.
[0005] Therefore, it is necessary to propose a kind of artificial hatching device of undulant lip fish, to solve the above problems. Utility Model Content
[0006] Aiming at the problem that the survival rate of fry of undulating bream is low when hatching, the utility model proposes a new artificial hatching device for undulating bream.
[0007] In order to solve the above technical problems, the utility model provides an artificial hatching device for rippled lip fish, comprising: a reflux purification tank, a hatching tank and multiple hatching containers, multiple hatching containers are clamped in the hatching tank, the hatching container is in the shape of a hollow bullet, a filter port is opened on one side of the top of the hatching container, and a 60-mesh screening net is installed on the filter port. The reflux purification tank is arranged on one side of the hatching tank, and a water pump is installed at the bottom thereof. The outlet pipe of the water pump extends into the hatching tank at one end away from the water pump and is connected to multiple branch pipes. The branch pipes are inserted into the hatching containers and are arranged one-to-one corresponding to the hatching containers.
[0008] In a preferred embodiment of this solution, a card plate is horizontally mounted in the middle of the hatching tank, and a plurality of slots are provided on the card plate, and the hatching containers are inserted into the slots one by one.
[0009] In a preferred embodiment of the present scheme, a purification tank and a reflow tank are formed separately by partitions in the reflux purification tank. The purification tank is 80 mm lower than the top of the incubation tank, and the top of the reflow tank is flush with the top of the incubation tank. An overflow port is provided on the top of the tank wall between the purification tank and the incubation tank, and the bottom side of the overflow port is not higher than the top of the purification tank.
[0010] Furthermore, the water pump is arranged in the reflux tank, and a filter window is provided on the partition between the reflux tank and the purification tank, and a filter screen with a mesh size greater than 100 is installed on the filter window.
[0011] The implementation of this utility model has the following beneficial effects:
[0012] The artificial hatching device for rippled lip fish can make newly hatched fry roll up and down while maintaining stable water quality, effectively avoiding the water flow dead corners and micro-bubbles that damage the fry caused by the traditional air stone inflation method used in hatching fry, as well as the frequent occurrence of bubbles bursting and pushing the fry out of the water, drying out or sticking to the pool wall and causing them to die.
[0013] The water flow inside and outside the hatching container is exchanged through the screening net on the hatching container. The proteins and mucus produced by the metabolism of the fry during the hatching process will also escape through the screening net. The exchanged impurities then enter the purification tank from the overflow port. The upper part of the purification tank is equipped with biochemical cotton attached with nitrifying bacteria and Bacillus to filter the water and decompose and absorb dissolved organic matter. The lower part is equipped with bioballs attached with denitrifying bacteria. After decomposition and filtration by bacteria, the water is returned to the hatching tank through the water pump, forming a cycle, thereby keeping the water fresh and improving the hatching survival rate of the rippled lip fish after hatching.
