Description

Crab shrimpfish recirculation system
Technical field
The invention belongs to technical field of aquaculture, be specifically related to a kind of crab shrimpfish recirculation system.
Background technology
Crab, shrimp be pool cultivated refer in pond, to carry out river crab, several breeding way such as freshwater shrimp, cray, crab shrimp are raised together with, this several breeding way, carry out river crab, freshwater shrimp, cray monoculture, or these kinds are raised together with, do not carry out fish in general crab shrimp pond and raise together with.
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.
Crab shrimp aquaculture due to output lower, general per mu yield only has about 100 kilograms, causes water body availability not high; Flowing water culture output is high, but needs to consume a large amount of water resources, and produces a large amount of pollutants; There is the higher problem of cost of water treatment in circulating water cultivation.
Summary of the invention
The object of this invention is to provide a kind of crab shrimpfish recirculation system, crab shrimp and fish are raised together with, improve water surface availability, output is high, reaches the effect of cyclic culture.
For achieving the above object, the technical solution adopted in the present invention is: a kind of crab shrimpfish recirculation system, and it is two crab shrimp ponds that crab shrimpfish recirculation system is separated by ridge, puts spiral shell, crab or shrimp in a suitable place to breed in each crab shrimp pond; The two ends of ridge have flowing water pond, stocked carp in each flowing water pond, oxygenation facility is equipped with in the bottom in each flowing water pond, and fan blower is equipped with in the upstream in flowing water pond, downstream is provided with the dirty pond of collection, the upstream and downstream direction in flowing water pond is vertical with ridge to be arranged, and collects dirty pond built with soil pick-up pump; Be provided with water vermiculture pond with collection dirty pond adjacent position in crab shrimp pond, in water vermiculture pond, inoculate water earthworm.
Preferably, the size of crab shrimpfish recirculation system is 15-30 mu, and the quantity in the flowing water pond that ridge is often held is 2-3, and the size in each flowing water pond is 110-130 ㎡; Collect dirty pond and be positioned at the downstream position of often holding flowing water pond, integrate the 1/15-1/25 of size as the total size of ridge one end all flowing water pool area in dirty pond, the area in water vermiculture pond is the 40%-60% of all flowing water pool areas in ridge one end.
Preferably, the size in each flowing water pond is 120 ㎡, and integrate the size in dirty pond as 1/20 of the total size of ridge one end all flowing water pool area, the area in water vermiculture pond is 50% of all flowing water pool areas in ridge one end.
Preferably, described fish are the one in perch, snakehead, grass carp and black carp.
Preferably, described fish size be 20-50 tail/kilogram, breeding density be 150-200 tail/square metre, water body exchange frequency be every 1.5 minutes exchange 1 time.
Preferably, the pond stalk of described crab shrimpfish recirculation system has ecological canal, the organic matter collecting fish excretion in dirty pond enters crab shrimp pond and water vermiculture pond, and the water body in water vermiculture pond flows into ecological canal, flows into crab shrimp pond through purifying waste water of ecological canal.
Preferably, in crab shrimp pond, plant pasture and water, shoal plantation very water water plants, by the quantity inoculation water earthworm of 0.5 kilogram/square metre.
Preferably, the water bottom in water vermiculture pond and ecological canal inoculates water earthworm, top plantation aquatic vegetable, and water earthworm inoculation quantity is 1 kilogram/square metre, and the coverage rate of aquatic vegetable is 60-80%.
Preferably, described aquatic vegetable is water spinach or Chinese celery, and the coverage rate of aquatic vegetable is 70%.
Preferably, in crab shrimp pond, every mu of cover supports silver carp 30 tail and/or variegated carp 10 tail.
After adopting technique scheme, the present invention has following good effect:
(1) the present invention sets up flowing water pond in crab shrimp pond, carries out fish culture, and the discarded object of fish enters water vermiculture pond by concentrated blowdown on the one hand and ecological canal carries out purified treatment; Entering crab shrimp pond carries out rich water on the other hand, and is purified by pasture and water in pond.Simultaneously, the dissolved oxygen in crab shrimp pond is improve by flowing water, like this, substantially increase water surface availability on the one hand, add yield per unit area, ight soil, the residual bait of another aspect fish are absorbed by water earthworm, aquatic vegetable, plankton, pasture and water, reach the object of ecologic breeding, water circulation use;
(2) the present invention is by building more suitable growing environment for fish, and compared with cultivating with ordinary pond, fast growth more than 10%, dosage reduces 60%.Crab, shrimp pond flow into owing to constantly there being organic matter, add that dissolved oxygen enriches, and benthon and pasture and water grow vigorous, by aquaculture water earthworm, both consume organic matter, again for crab, shrimp add animal protein sources, enhance immunity, make crab, shrimp volume increase more than 10%.Crab shrimpfish recirculation system of the present invention, makes water surface availability improve more than 1 times, and reach the effect of low-carbon (LC), efficient, ecological, circulation, solve breeding pollution problem, controllability is strong, and disease is few, and aquatic products listing is flexible for season.
