Embodiment 1

[0020] Example 1: In the sea area of ​​Zhoushan, from November to May of the next year, the culture of large yellow croaker is changed from cage culture in natural sea area to pond culture in plastic greenhouses.

[0021] Starting catch: before the end of November, when the water temperature drops to 12°C, start to catch large yellow croakers. When starting to catch, choose during the small tide period, preferably at night, stop feeding for 1 day before starting to catch, and collect fish in the corner of the cage when starting to catch, and use the automatic fish suction pump to catch; Large yellow croakers are transported and sold by running water trucks or boats; large yellow croakers weighing less than 500g and not reaching the market size are transferred to plastic greenhouses for pond breeding.

[0022] There are gas-dispersing stones at the bottom of the pond in the plastic greenhouse, and one gas-dispersing stone is arranged every 5 square meters. The roof is made of ...

Embodiment 2

[0025] Example 2: In the sea area of ​​Zhoushan, from November to May of the next year, the culture of large yellow croaker is changed from cage culture in natural sea area to pond culture in plastic greenhouses.

[0026] Starting catch: before the end of November, when the water temperature drops to 15°C, start to catch large yellow croakers. When starting to catch, choose during the small tide period, preferably at night, stop feeding for 2 days before starting to catch, and collect fish in the corner of the cage when starting to catch, and use the automatic fish suction pump to catch; Large yellow croakers are transported and sold by running water trucks or boats; large yellow croakers weighing less than 500g and not reaching the market size are transferred to plastic greenhouses for pond breeding.

Embodiment 3

[0030] Example 3: In the sea area of ​​Zhoushan, from November to May of the next year, the culture of large yellow croaker is changed from cage culture in natural sea area to pond culture in plastic greenhouses.

[0031] Starting catch: before the end of November, when the water temperature drops to 13°C, start to catch large yellow croakers. When starting to catch, choose during the small tide period, preferably at night, stop feeding for 2 days before starting to catch, and collect fish in the corner of the cage when starting to catch, and use the automatic fish suction pump to catch; Large yellow croakers are transported and sold by running water trucks or boats; large yellow croakers weighing less than 500g and not reaching the market size are transferred to plastic greenhouses for pond breeding.

Abstract

The invention discloses a method for performing wintering breeding on large yellow croaker. The large yellow croaker is bred in the Zhoushan sea area, natural sea area net cage breeding is converted into plastic greenhouse pond breeding from yearly November to May in the next year, catch is performed on the large yellow croaker at the end of November, the large yellow croaker is placed in a plastic greenhouse pond, perforated stone is placed at the bottom of the plastic greenhouse pond, a plastic thin film is arranged on the ceiling of the plastic greenhouse pond, natural sea water is adopted as main water of the plastic greenhouse pond, and an underground deep well geothermal water and steam warming facilities are matched. Nutrient enrichment is performed on the large yellow croaker, and betaine hydrochloride and vitamin C powder are added in fodders. In the winter and early spring seasons, the large yellow croaker is bred in the plastic greenhouse pond, the temperature of the water area is controlled, meanwhile, in the breeding process, nutrient enrichment is performed, and the survival rate of the large yellow croaker breeding in the winter and early spring seasons is improved.

Description

technical field [0001] The invention relates to the technical field of fish overwintering, in particular to a method for overwintering large yellow croaker. Background technique [0002] Large yellow croakers are mainly distributed in the East China Sea and the southern coast of China. Due to its fast growth, strong disease resistance, delicious meat and high nutritional value, large yellow croaker is welcomed by consumers at home and abroad. It is one of the most potential targets for intensive marine fish farming in the future. The suitable temperature range for the survival of large yellow croaker is 8-34°C, the optimum growth water temperature is 18-28°C, the feeding temperature is 10-32°C, and the safe temperature for overwintering is 10°C. [0003] Zhejiang Zhoushan sea area is located at the estuary of the Yangtze River, Qiantang River, and Yongjiang River. The coastal current, the Taiwan warm current and the cold water mass of the Yellow Sea meet here. It is rich in...
