Problems solved by technology

my country's silver carp aquaculture industry has made great achievements in recent years, and the aquaculture method has also transitioned from extensive to intensive and semi-intensive aquaculture. However, the aquaculture production is basically based on ponds with still water and no sewage. The consequences of easy accumulation of toxic substances, deterioration of water quality, and induction of fish diseases

Abstract

The invention discloses an ecological breeding method for chubs. The method comprises the following steps: (1) managing a culture pond: injecting water in 0.2-0.4 m depth into a pond, increasing the water level in the pond to 1-1.5 m after planting aquatic plants at the bottom of the culture pond in the density of 250-400 plants / 100m<2> for 10-15 days, applying a diatom seed solution on the basis of the dosage of 600-1300g / 100m<2> and culturing diatom seed for 10-15 days under the conditions of water temperature of culture pond at 20-25 DEG C and illumination intensity of 2000-3500 lx; (2) disinfecting and managing fish fries; and (3) managing feeding. The technological method adopted by the invention can be used for effectively culturing chubs by adopting an ecological system; the yield of the chubs is increased; the disease resistance of the chubs is promoted; the water quality of the culture pond is improved; the method is suitable for long-term large-area popularization and has ultrahigh marketing value.

Description

[0001] 【Technical field】 [0002] The invention relates to the cultivation field of silver carp, in particular to an ecological cultivation method of silver carp. [0003] 【Background technique】 [0004] Silver carp, also known as silver carp, water carp, jumping carp and silver carp, belongs to Cyprinidae, Cyprinidae, and is one of the four famous big fishes. The body is flat on the sides, slightly taller, spindle-shaped, blue-gray on the back, white on both sides and abdomen, with a large head, low eye position, and small scales. The horny ridge in the middle of the abdomen extends from the bottom of the pectoral fins to the anus, and the pectoral fins do not exceed the base of the pelvic fins, and each fin is grayish white. Similar in shape to bighead carp, silver carp is impatient and good at jumping. Silver carp is a large-scale freshwater fish raised artificially. It grows fast, has few diseases, and has a high yield. It is mostly mixed with grass carp and carp. Its me...
