Abstract
The invention provides a method for breeding snakehead through circulating running water, and belongs to the technical field of running water breeding. The method comprises the steps that four running water pools with the area of 120 m<2> are built on one side of a fish pool with the area of 40 mu, a sewage collection pool with the area of 100 m<2> is arranged on the downstream of the running water pools, the upstream of each running water pool is provided with a Roots blower, and the bottom of each running water pool is provided with a micro hole oxygenation facility; 150-200 snakehead fingerlings with the specification of 200/kg are placed in each square meter of the running water pools, chub is placed in the pools based on the density of 200/667 m<2>, bighead carp is placed in the pools based on the density of 30/667 m<2>, a small amount of crucian carp can also be placed in the pools, and some aquatic plants are planted at shallow water positions; puffing compound feed containing 40-44% of protein is fed to the snakehead in the whole process, the daily feeding amount is about 5% of the weight of the snakehead, and artificial food is not fed to the fishes in the pools. According to the method, a more appropriate growing environment is built for snakehead, and compared with common pool breeding, the growth speed is improved by 10% or more, the yield is improved by 25%, and the medicine consumption is reduced by 60%.
Description
Technical field
The present invention relates to a kind of method of cycle water flowing water culture snakehead, belong to flowing water culture technical field.
Background technology
Snakehead (Channaargus) belongs to Perciformes, murrel section, Ophiocephalus.Be commonly called as: snakehead fish, snakeheaded fish, snakeheaded fish, crow rod, snakehead shape are in long bar-shaped.Head is flat, and head is large, and schistostoma is large.Rhynchodaenm is circular.In mouthful, teeth are grown thickly.Paired fin is all little, dorsal fin and anal fin speciality, and tail fin is circular.Head and trunk are all by the scale having size similar.Side line is complete, has individual bending at the rear of pectoral fin.There are many sensation apertures in crown portion, and its number of large fish is more.Body colour back celadon, belly is greyish white, and there is the obvious blackstreak doing splayed arrangement on side.Head has three to the striped stretched out backward.Snakehead is the powerhouse in the Shui nationality, and it likes inhabiting the luxuriant or muddy bottom of pasture and water at ordinary times, and when the trip such as small fish, shrimp is near, it just makes a surprise attack and to be gulped down by these small animals, and the snakeheaded fish of 0.5 kilogram can gulp next two or three double grass carps or carp.The vitality of snakeheaded fish is very strong, ranks first in freshwater fish.Someone did experiment, snakeheaded fish was placed on moist shady and cool land, first quarter moon of can living.Because general fish inspiration can only be dissolved in oxygen in water, and snakeheaded fish directly can also absorb the oxygen in air, it relies on this " exceptional function ", when suffering from a severe drought, when lake water is about to withered, it can as some animal hibernation, namely in dormancy state, at this moment its afterbody is sat health enter in mud down, only stays face to be exposed at more than mud face, be commonly called as snakeheaded fish and " sit short wooden stake " or " sit escape ", " drought is slept " of Here it is snakeheaded fish.At this moment it is in stupefaction, sustainable several weeks, and when waiting again water, snakeheaded fish just recovers normal life.
Snakehead is distributed widely in waters, east China each province.Its delicious meat, nutritious is the aquatic products that a kind of economic worth is higher.China was once a country abounding with snakehead.Make the natural resources of snakehead significantly reduce for various reasons over nearly 30 years, snakehead has become the rare product in aquatic product.In recent years; for complying with the needs of domestic and international trading market; many areas have been carried out the scientific research propagating snakehead artificially and have been put into practice with cultivation; have accumulated many successfully experiences; especially the breakthrough of seed breeding technology and hand fit's special feed, for snakehead aquaculture move towards commercialization, large-scale production is laid a good foundation.The main method of current snakehead cultivation is pond fish farming, the cage culture of flood face, substantially without flowing water culture.
Flowing water culture is the water body utilizing constantly flowing, carries out the cultivation of aquatic animal.Have that the culture-cycle is short, area occupied is little, density is high, output is high, the feature such as high efficiency and convenient management.Flowing water culture water body is constantly updated, and enables the ramp under the conditions such as optimum water temperature, water quality, dissolved oxygen, bait of the fish of cultivation.The principal mode of current flowing water culture has nature flowing water culture, warm flow water to cultivate and industrial circulating water flowing water culture.
Circulating water cultivation is a kind of breeding way recycled after aeration, precipitation, sterilization, filtration breeding water, and current circulating water cultivation water position reason is all through mechanical treatment, or special ecological canal processes.
Summary of the invention
In order to overcome the deficiencies in the prior art, for not high, the with serious pollution problem of existing pond culture output, the invention provides a kind of method of cycle water flowing water culture snakehead.
A method for cycle water flowing water culture snakehead, is characterized in that it comprises the following steps:
First, build the flowing water pond of 4 each 120 square metres in the fishponds of 40 mu, 100 square metres of dirty ponds of collection are built in downstream, flowing water pond, and upstream, each flowing water pond is respectively installed one and pushed away water machine, and stream basin bottom installs micro-pore oxygenation facility.
Secondly, in flowing water pond stocking size be 200 tails/kilogram above snakehead kind 150-200 tail/square metre, put silver carp 200 tail/667 square metre in pond in a suitable place to breed, bighead 30 tail/667 square metre, also can put a small amount of crucian, and shoal plants part water plants.
3rd, snakehead whole process is thrown something and fed containing the expanding compound feed of protein 40-44%, and daily ration of feeding is about 5% of fish body weight, and the fish in fishpond are not are not thrown something and fed artitificial food.
Beneficial effect of the present invention:
The present invention is by building more suitable growing environment for snakehead, and compared with cultivating with ordinary pond, fast growth more than 10%, output exceeds 25%, and dosage reduces 60%.
The present invention is simple, and easy, output is high, has good promotional value.
