Embodiment 1

[0026] A low-salinity recirculating water culture method for Australian jewel perch, comprising the following steps:

[0027] (1) Purchase fish fry with an average weight of 30-35g, first soak and disinfect them with 2.5% salt water for 3 minutes, and then put them into a circulating pool with a salt water concentration of 0.8% to raise them. The stocking density is 230 fish / m 3 The circulating pool is equipped with a 24-hour ultraviolet disinfection lamp to continuously disinfect the circulating water, and ensure that the ultraviolet disinfection lamp cannot be irradiated on the gem perch; at the same time, a microbial filter tank is set to purify the water quality; the inside of the microbial filter tank is provided with fillers, and the The fillers are biochemical cotton, pebbles, activated carbon, medical stone and volcanic rock from top to bottom, and the fillers are replaced every 90 days.

[0028] (2) During the breeding process, feed the gemstone perch special feed; ch...

Embodiment 2

[0030] A low-salinity recirculating water culture method for Australian jewel perch, comprising the following steps:

[0031] (1) Purchase fish fry with an average weight of 30-35g, first soak and disinfect them with 3.5% salt water for 7 minutes, and then put them into a circulating pool with a salt water concentration of 1.5% to raise them. The stocking density is 240 fish / m 3 The circulating pool is provided with a 24-hour ultraviolet disinfection lamp to continuously disinfect the water, and to ensure that the ultraviolet disinfection lamp cannot be irradiated on the gemstone perch; at the same time, a microbial filter tank is set to purify the water quality; the inside of the microbial filter tank is provided with fillers, so The fillers described above are biochemical cotton, pebbles, activated carbon, medical stone and volcanic rock from top to bottom, and the fillers are replaced every 120 days.

[0032] (2) During the breeding process, feed the gemstone perch special ...

Embodiment 3

[0034] A low-salinity recirculating water culture method for Australian jewel perch, comprising the following steps:

[0035] (1) Purchase fish fry with an average weight of 30-35g, first soak and disinfect them with 3.0% salt water for 5 minutes, and then put them into a circulating pool with a salt water concentration of 1.0% to raise them. The stocking density is 250 fish / m 3 The circulating pool is equipped with a 24-hour ultraviolet disinfection lamp to continuously disinfect the circulating water, and ensure that the ultraviolet disinfection lamp cannot be irradiated on the gem perch; at the same time, a microbial filter tank is set to purify the water quality; the inside of the microbial filter tank is provided with fillers. The fillers described above are biochemical cotton, pebbles, activated carbon, medical stone and volcanic rock from top to bottom, and the fillers are replaced every 100 days.

Abstract

The invention relates to the field of aquaculture, in particular to a method for low-salinity circulating aquaculture of scortum barcoo. According to the method, fish fries are immersed in high-salinity water to be sterilized, freshwater bacteria and parasites can be effectively killed or the number of freshwater bacteria and parasites can be effectively reduced through salinity change, and then bacterium and parasite infection rate of fish fries is reduced. In the culturing process, the content of bacteria and parasites in circulating water is low, the growth environment of scortum barcoo is relatively clean, and therefore no drug is needed during culture so that the quality of aquatic products can be improved greatly.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a low-salinity recirculating aquaculture method for Australian jewel perch. Background technique [0002] Jade Perch, also known as jewel perch and jewel fish, is native to the freshwater waters of Australia and is the only famous freshwater fish species distributed in Australia. It was first evolved from seawater fish, so it not only maintains the tenderness of freshwater fish, but also has the unique deliciousness of seawater fish. The shape of the jewel fish is very attractive, its body color is silver and bright, and there are several black shiny oval plaques on the side of the body, just like black gemstones inlaid on the surface of the fish body, so it is called "jewel fish". [0003] Trial breeding proves that gem perch has the advantages of fast growth, miscellaneous food habits, low oxygen resistance, strong adaptability and strong disease resistance. It can be cultured in hi...
