specific Embodiment approach 1

[0010] Specific embodiment one: the high-efficiency cultivation method of a kind of carp zero-change water pond of the present embodiment is carried out according to the following steps: one, pond condition: pond area 5~15 mus, pond water body depth 1.8~2.5 meters, be equipped with bait feeder One set, equipped with an aerator at 0.7-1 kilowatt per mu; 7-10 days before the fish species are stocked, dry disinfection with quicklime, the amount of quicklime is 70-75 kg / mu;

[0011] 2. Stocking of fish species: select fish species with neat specifications, complete body surface, no deformity, no disease and no injury; stocking density and specifications are as follows: Songpu mirror carp 100-110kg / mu, specification 100-200g / tail; silver carp 20-25kg / mu, size 50-100g / tail; bighead carp 10-16kg / mu, size 50-100g / tail; grass carp 5-8kg / mu, size 100-200g / tail;

[0012] 3. Feed feeding: The feed for feeding is commercial fish compound feed; when feeding each meal, 60-70% of the fish lea...

specific Embodiment approach 2

[0018] Specific embodiment two: what this embodiment is different from specific embodiment one is that in step 2, stocking density is Matsuura mirror carp 105kg / mu; Silver carp 22.5kg / mu; Bighead carp 15kg / mu; Grass carp 7.5kg / mu. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step three, the food is fed 4 times a day. Others are the same as in the first or second embodiment.

Abstract

An efficient carp farming method by using a free-of-water changing pond relates to a carp farming method. The efficient carp farming method aims at solving the problems of low farming efficiency, serious per se pollution to a farming water body and low survival rate of carps existing in the traditional farming method. The efficient carp farming method provided by the invention comprises the following steps: 1. setting of pond conditions; 2. fish seed farming; 3. feedstuff feeding; 4. farming management; and 5. regulation and control of water quality. The efficient carp farming method has the advantages of being free of discharging of farming sewage in the farming process and pollution to surrounding environments and capable of effectively increasing the survival rate of carps. The efficient carp farming method is applied to the field of carp farming.

Description

technical field [0001] The invention relates to a carp breeding method. Background technique [0002] At present, most of the culture of carp has followed the traditional pond culture mode of changing water. However, the traditional pond culture of fish is carried out at the cost of consuming a large amount of natural resources, that is to say, the occupation of land resources is increasing, the consumption of water resources is increasing, and the consumption of biological resources is increasing. , and during the breeding process, a large amount of organic matter such as residual bait, feces, corpses of dead organisms, and sediments in aquaculture water accumulates, and the content of ammonia nitrogen and nitrite increases significantly, posing a serious threat to farmed fish and the surrounding environment. Carp The survival rate of the species is only about 85%, which seriously hinders the sustainable and healthy development of pond culture. Therefore, it is imperative...
