Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the process figure of the shrimp crab mixed cultivation method of embodiment of the present invention ecological efficient.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the process figure of the shrimp crab mixed cultivation method of embodiment of the present invention ecological efficient; This cultural method comprises the steps: that a) pond is selected and facility is equipped with, and b) put front preparation in a suitable place to breed, c) seed is put in a suitable place to breed, d) bait feeding, e) water quality adjustment, f) dailyly patrols the pool and disease control.
The shrimp crab mixed cultivation method of the ecological efficient that the present invention mentions is put in a suitable place to breed by preparation before improving pond condition, refinement cultivation, reasonable arrangement seed, scientific and normal aquaculture management, achieves the high yield of freshwater shrimp and river crab, greatly improves economic benefit.Wherein, the cultivation of freshwater shrimp divided for two seasons carried out, and the 1st season put in a suitable place to breed mid-February, and 4 ~ July catches to stay greatly with cage net and littlely to go on the market in batches; 9 ~ November caught to stay greatly with cage net and littlely to go on the market in batches in putting in a suitable place to breed by the end of July 2nd season.The cultivation of river crab starts to put in a suitable place to breed in by the end of February, and 9 ~ November fishes for listing in batches, and prawn, crab carry out concentrating dry pond to fish for listing by the end of November.Adjust through actual tests cultivation, annual benefit can reach 10,000 yuan/667m
2above.
Embodiment
Concrete cultural method is as follows:
A) pond is selected and facility outfit, first chooses the pond near lake, and its slope is than being 1:3, and pond can reach 2m deeply; Then around intake, use netting fence, the close screen cloth in water inlet outer end seals, and prevents wild fishes etc. from entering, and seals in case freshwater shrimp flight at delivery port with close screen cloth; Subsequently micro-pore oxygenation equipment is installed in pond, altogether supporting 2 paddle aerators.
B) put front preparation in a suitable place to breed, prepare before putting in a suitable place to breed to comprise: sterilization of cleaning up the pond, plantation waterweed, organic fertilizer cultivate water quality.Wherein, pond, carrying out by the end of December, is first drained by sterilization of cleaning up the pond, remove the mud that bottom is unnecessary again, then shine pool 10d, be filled to 20cm afterwards dark, carry out disinfection with quicklime water full pond of splashing again, drain pond again after 3d and shine pool 20d, finally discharging water dark to 40cm.Plantation waterweed adopts interval planting patterns, spacing 60cm, and distribute in strip, its area coverage accounts for 60% of full pool area.Organic fertilizer is cultivated water quality and is being carried out by the end of February, is first filled to 50cm dark, re-uses decomposed manure by 40kg/667m
2consumption applies at the bottom of pond, makes the agreeable to the taste bait of seed with the plankton such as culture of rotifera, cladocera.
C) seed is put in a suitable place to breed, and the seed process of putting in a suitable place to breed is: first in mid-February by 23kg/667m
2stocking rate throws in the 1st batch of freshwater shrimp, and freshwater shrimp specification is 1600 tails/kg; Then 1300/667m is being pressed by the end of February
2breeding density throws in river crab kind, and first by iodine sterilization crab kind before putting in a suitable place to breed, crab kind specification is 200/kg; Pressing 50000 tails/667m by the end of July subsequently
2breeding density throws in the 2nd batch of freshwater shrimp, and freshwater shrimp specification is 10000 tails/kg.
D) bait feeding, bait feeding process is: throw something and feed in 2 ~ April protein content 36% pellet, small fish and corn, their amount ratio is 1:4:1, throws something and feeds twice every day, 40% feed of throwing something and feeding the morning, 60% feed of throwing something and feeding afternoon.500kg/667m is pressed at the beginning of 4 months
2consumption disposable input high-quality spiral shell, the living bait as river crab is originated, and purifies water simultaneously.Throw something and feed in 5 ~ August protein content 32% pellet and corn, their amount ratio is 1:1, throws something and feeds twice every day, 35% feed of throwing something and feeding the morning, 65% feed of throwing something and feeding afternoon.Throw something and feed in 9 ~ November protein content 32% pellet and small fish, their amount ratio is 2:5, throws something and feeds twice every day, 30% feed of throwing something and feeding the morning, 70% feed of throwing something and feeding afternoon.
E) water quality adjustment, water quality adjustment process is: to splash Freamine Ⅲ every 20d at spring and autumn, keeps water transparence at 30cm; Summer uses a microorganism formulation every 10d, keeps water transparence at 40cm; Summer high temperature controlling water level in season is at 1.5m; In good time unlatching aerator, keeps dissolved oxygen in water to be greater than 5mg/L.
F) dailyly the pool and disease control is patrolled, the daily pool of patrolling comprises and patrols the pool morning once a day and patrol the pool evening once a day, by looking into variation of water, looking into shrimp crab feeding activity situation, looking into disease harmful animal invasion and attack situation, carry out Timeliness coverage abnormal conditions and take corresponding measure to avoid and reduce the loss.Disease control mainly prevents and treats cilium insect pest, in March and susceptible disease period in April, monthly adopts fine worm clean, by 250g/667m
2consumption full pool spilling head, then use iodine solution sterilization every other day.
Present invention is disclosed a kind of shrimp crab mixed cultivation method of ecological efficient, this cultural method by arranging rational cultivating condition, the feeding and management method of science, both ensure that two season freshwater shrimp and the growing up healthy and sound of river crab, greatly improve again output and benefit.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
