[0084] When the daily average water temperature in the pond is 8°C, put the silver anchovy fry with a size of 4.5-7.0g in the pond, and the stocking density is 300 fish / 667m 2 , after putting in the silver anchovy 5 days, cultivate zooplankton in the pond and / or throw in zooplankton in the pond, and adjust the existence of zooplankton in the pond, make:

[0085] When the daily average water temperature in the pond is 9-20°C, the density of zooplankton in the pond is 5ind. / mL; when the daily average water temperature in the pond is 21-30°C, the density of zooplankton in the pond is 10ind. / mL, When the daily average water temperature of the pond is 5-8°C, the density of zooplankton in the pond is 3 ind. / mL.

[0086] 15 days after putting in the anchovy, put Macrobrachium japonicus and gobies in the pond and adjust the presence of Macrobrachium japonicu...

Embodiment 3

[0092] This embodiment is used for illustrating the method for cultivating the silver anchovy pond provided by the invention.

[0093] When the daily average water temperature in the pond is 12°C, put the silver anchovy fry with a size of 4.5-7.0g in the pond, and the stocking density is 500 fish / 667m 2 , after 7 days of putting in the anchovy, cultivate zooplankton in the pond and / or release zooplankton in the pond, and adjust the existence of zooplankton in the pond, so that:

[0094] When the daily average water temperature in the pond is 9-20°C, the density of zooplankton in the pond is 10ind. / mL; when the daily average water temperature in the pond is 21-30°C, the density of zooplankton in the pond is 15ind. / mL. When the daily average water temperature of the pond is 5-8°C, the density of zooplankton in the pond is 5 ind. / mL.

[0095] 20 days after putting in the anchovy, put Macrobrachium japonicus and gobies in the pond and adjust the presence of Macrobrachium japonicu...

Abstract

The invention discloses a method for pond culturing Coilia ectenes, which is characterized in that the method comprises the following steps of putting Coilia ectenes in a pond, culturing the Coilia ectenes with the existence of zooplankton, Macrobrachium nipponensis and gobies, wherein the Coilia ectenes forms a balanced biological nutrition chain with the zooplankton, the Macrobrachium nipponensis and the gobies due to the existence quantity of the zooplankton, the Macrobrachium nipponensis and the gobies. With the adoption of the method for pond culturing the Coilia ectenes provided by theinvention, the biological nutrition chain with complementary ecological functions can be established among the Coilia ectenes, the zooplankton, the Macrobrachium nipponensis and the gobies in the aquaculture water; delectable flavor and proper quantity of the in-taken food of the Coilia ectenes can be ensured; the survival rate of the Coilia ectenes can be up to 90%; the Coilia ectanes can be grown above 100 g from about 5 g in two years, thus, a large scale of commercial Coilia ectenes can be formed, and the cultured Coilia ectenes has high qualities, the unsaturated fatty acid content in the meat is up to 6.8% and the collagen content is up to 0.3%. Therefore, the method has a high promotion value.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating cuttlefish in a pond. Background technique [0002] Coilia nasus, belonging to Clupeiformes, Engraulidae, genus Coilia, also known as long-jawed coilia, commonly known as hairy fish, shaving fish, hairy fish, swordfish, mainly distributed in China In the area of ​​the Yellow Bohai Sea and the East China Sea, all rivers leading to the sea such as the Yangtze River, Qiantang River, Yellow River, Huaihe River, and Liaohe River are distributed along the coast. Among them, the Yangtze River Basin has a high and concentrated output. It is famous for its plump fat and tender and delicious meat. It is a rare migratory fish that enjoys the reputation of "three delicacies of the Yangtze River". [0003] However, since the 1970s, due to the pollution of my country's water bodies and changes in hydrological conditions, the spawning grounds have been destroyed, especi...
