Embodiment 1

[0022] (1) On March 1 of a certain year, 300 parents of money fish were purchased from the market, and four broodstock breeding ponds were prepared, the water level was 80cm, the salinity was 25-33‰, and each pond was equipped with a constant temperature machine. Two pools were used for cultivation (A, B), and two were spared.

[0023] (2) On March 10 of a certain year, the natural water temperature was 22°C, and broodstock selection was carried out. Select uninjured individuals with smooth body surface as parents, 45 female parents (body weight 300-500g, body length 180-220mm), 45 male parents (body weight 145-210g, body length 165-179mm), and pool B Select 45 female parents (weight 500-1000g, body length 200-275mmmm), 45 male parents (weight 200-500g, body length 150-250mm), 2g / m 3 Bromochlorohydantoin was transferred to the parent breeding pool after disinfection treatment, and the number of parents in each pool was 90.

[0024] (3) After the parents were selected and sta...

Embodiment 2

[0028] (1) On March 15th of a certain year, prepare six broodstock breeding ponds. The breeding ponds are indoor semi-buried cement ponds. Cover the top of the ponds with thermal insulation film and inject seawater filtered by sand. The water level is 100cm and the salinity is 25. -33‰, each pool is equipped with a constant temperature machine. Four pools were used for cultivation (A, B, C, D), and two were spared.

[0029] (2) On March 16 of a certain year, the natural water temperature was 21.4°C, and broodstock selection was carried out. Choose uninjured individuals with smooth body surface as parents, and only feed No. 5 Jianma brand golden pomfret compound feed in pool A, and No. 5 Jianma brand golden pomfret compound feed in pool B. The fresh and live bait is shelled weed For razor clams and clam worms, the feeding ratio of compound feed to fresh bait is 4:1, and the daily feeding amount is 2-6% of the fish body weight. The C pond is all male parents, cultured at natura...

Embodiment 3

[0034] (1) On March 12 of a certain year, four broodstock breeding ponds were prepared. The breeding ponds were indoor semi-buried cement ponds. The top of the ponds was covered with thermal insulation film, and the seawater filtered by sand was injected. The water level was 100cm and the salinity was 25. -33‰, each pool is equipped with a constant temperature machine. Two pools are used for cultivation (A, B), and two are reserved.

[0035](2) On March 15 of a certain year, the natural water temperature was 22.4°C, and broodstock selection was carried out. Choose uninjured, smooth body surface, individual as the parent, A pool is injected with ripening hormone in 5 and 6 months, and B pool is not injected with ripening hormone in 5 and 6 months, 2g / m 3 Bromochlorhydrinated hydantoin was transferred to parent breeding pools after disinfection treatment, with 50 male and female parents in each pool, 100 in total.

[0036] (3) After the parents were selected and stabilized in ...

Abstract

The invention relates to an efficient artificial intensified cultivation method for scatophagus argus parents. The method comprises the technical means of cultivation pond selection, parent selection, water quality regulation and control, bait feeding, male and female separate cultivation, hormone ripening acceleration and the like, the cultivated scatophagus argus parent is high in maturation rate, male and female gonad development is synchronous, and a guarantee is provided for scatophagus argus large-scale breeding.

Description

technical field [0001] The invention belongs to the field of fish reproduction, and in particular relates to a method for highly efficient and artificially intensified cultivation of the parents of money fish. Background technique [0002] Money fish (Scatophagus argus), also known as golden drum fish, belongs to the order Perciformes, family Scatophagidae, and the genus Scatophagus. The money fish is a euryhaline subtropical fish, which is widely distributed in the Indo-Pacific waters. In my country, it is distributed from the south of the East China Sea to the South China Sea and the Beibu Gulf. Money fish is an omnivorous fish that is mainly herbivorous and also carnivorous. It has strong environmental adaptability and disease resistance. It can grow and develop in seawater, brackish water or even fresh water. It has dual values ​​of food and ornamental , is expected to become an important species for large-scale farming in coastal ponds and cages in southern my country. ...
