Problems solved by technology

[0005] Although the above-mentioned patents can effectively prevent the corrugated lip fish from killing each other, the culture conditions of the corrugated lip fish are uncontrollable by hanging the corrugated lip fish in the sea through cages; and preventing fighting by means of isolation, the cost is high, and bait feeding is inconvenient, which is not conducive to Scale Conservation and Management of Rippled Lipfish

Embodiment Construction

[0016] The following is further described in detail through specific implementation methods:

[0017] This embodiment provides a kind of corrugated lip fish conservation method, when starting to nurse, put 15-30 corrugated lip fish in each nursery pool, construct conservation density≤5kg / m 3 (the weight of the largest corrugated lip fish) / (the weight of the next largest corrugated lip fish)≥3 (the larger the ratio, the better).

[0018] Plastic pipes are suspended in the nursery pond for the corrugated lip fish to avoid. In this embodiment, the preferred shielding member is a plastic pipe suspended in the nursery pond (through stones or sinkers). The diameter of the plastic tube is 20-80cm, and the length is 50-150cm. During the conservation process, it is adjusted according to the size of the corrugated lip fish. The standard is that it can provide the corrugated lip fish to avoid and not affect the growth of the fish. The corrugated lip fish is timid and easily frightened. ...

Abstract

The invention belongs to the technical field of tropical famous and precious seawater fish culture, and specifically discloses a conservation method for corrugated lip fish, and constructs a conservation density ≤ 5kg / m in each conservation pond 3 In the conservation group, (the weight of the largest corrugated lip fish) / (the weight of the second largest corrugated lip fish)≥3. The conservation method of the corrugated lip fish provided by the present invention can effectively prevent mutual killing behavior among the corrugated lip fish individuals by constructing a stable conservation group, reduce conservation loss and improve conservation survival rate, and at the same time appropriately increase conservation density, reduce conservation cost, improve conservation efficiency.

Description

technical field [0001] The invention belongs to the technical field of tropical famous and precious seawater fish culture, and in particular relates to a conservation method for the rippling fish. Background technique [0002] Cheilinus undulatus (Rüppell, 1835), also known as Sumei, is the largest member of the wrasse family and one of the larger bony fishes in the coral reef area. It is edible fish and can also be used as ornamental fish in aquariums or large display fish tanks. As fishing increases and coral reefs shrink, the number of wild bellfish is declining year by year. [0003] The corrugated lip fish has the following characteristics: (1) The corrugated lip fish has a long growth period. Male individuals generally need 7-8 years to reach sexual maturity and can survive for at least 30 years (25 years old for males and 32 years old for females). The chrysalis is a hermaphroditic premature fish. Most of the chrysalis keep their sex unchanged after birth, and only ...
