Embodiment Construction

[0034] Below in conjunction with embodiment, the present invention will be further described.

[0035] (1) Prepare the breeding pond

[0036] In March 2015, Anhui Hongjia Agricultural Science and Technology Co., Ltd. chose two breeding ponds. The breeding ponds are 1300㎡ rectangular earthen ponds, 70m long, 20m wide, and 1.8m deep, running from east to west. The upper edge of the southeast corner of each pond is provided with a water inlet, and at the bottom of the northwest corner of the pond, there is a water outlet, all of which are sealed with a 60 mesh screen. There is a "ten" ditch at the bottom of the breeding pond, with the center of the pond as the "ten" intersection point, the ditch depth of the "ten" ditch is 50cm, and the ditch width is 2.5m. Plastic partitions are used to protect the slope around the pond, and the slope ratio is 1:1.

[0037] (2) Fertilization and planting aquatic plants

[0038] In May, each hole was disinfected with quicklime, and 100 kg of q...

Abstract

The invention discloses an ecological breeding method of high-quality fancy carps. The method includes the following operating steps that 1, an aquaculture pond is prepared; 2, fertilization and waterplant planting are carried out; 3, sexual precocity freshwater shrimp fry are cultivated and delivered; 4, fancy carp fry are selected and delivered; 5, breeding management is carried out; 6, a fry replenishing measure is taken. The characteristics that sexual precocity freshwater shrimp individuals are small, the propagation time is about 15-20 days shorter than that of normal freshwater shrimps, and the rapid feeding growth periods of zoea and juvenile shrimps of the sexual precocity freshwater shrimps are completely consistent with those of the fancy carps are ingeniously utilized, the juvenile freshwater shrimps and adult freshwater shrimps can meet the requirements of the body type growth of the fancy carps on protein and the body color development on astaxanthin, the material flow relation between organisms of the aquaculture pond is creatively utilized fully, dynamic balance of material flow between the organisms is kept, and under the conditions without manual feeding strips and polluted water drainage, the high-quality fancy carps are bred. Meanwhile, the problem that during freshwater shrimp breeding, breeding economic benefits are affected due to sexual precocity of freshwater shrimps is solved, and the method is easy to operate and has remarkable economic, ecological and social effects.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating high-quality koi. Background technique [0002] Koi is a high-end ornamental fish, known as "living jewel in water" and "swimming artwork". The price of high-quality koi has always been high. Bright body color, regular stains, large and well-proportioned body are the main evaluation indicators of high-quality koi, but at present, due to improper breeding methods, the phenomenon of fading, color drift and deformity of pure koi is serious. During the growth process of koi carp, the maintenance of body shape and body color mainly depends on the ratio of various nutrients in artificial feed and additives such as carotene. hair and growth retardation. In order to solve the adverse effects of inappropriate feed nutrition ratio and excessive feeding amount on the growth, body shape and body color of koi carp in the koi breeding process, it is n...
