Description
Technical field
The utility model relates to prawn culturing field, particularly a kind of device removing cladocera in prawn culturing pond.
Background technology
Cladocera, be commonly called as " worm for fishing ", be under the jurisdiction of Arthropoda (Arthropoda), Crustachia (Crustacea), Branchiopoda (Babchiopoda), peg graft (Cladocera), is distributed widely in fresh water, seawater and inland brackish water.Cladocera wide adaptability, fertility is strong, and growth rapidly, and has high nutritive value, and dry weight crude protein content reaches about 55%, is the natural bait of many aquatic shellfishs, aquatic products economic fish fry rearing stage high-quality.In prawn culturing, in view of cladocera has suitable size, the feature be of high nutritive value, cladocera is very important natural bait in prawn seedling stage, simultaneously because cladocera can be eaten a large amount of bacteriums, so keep certain quantity can also play prawn culturing pond control pathogen, prophylactic effect.But, along with the growth of prawn, it strengthened increasingly to needing of ingesting of pellet and zoobenthos, more and more less to the demand of ingesting of cladocera, and the amount reproduction of cladocera self, during prawn culturing, often occur in cultivating pool that cladocera exists in a large number, breed the phenomenon of spreading unchecked, cladocera is not only ingested in a large number and is carried out the planktonic algae of photosynthesis oxygenation in cultivating pool water body, and cladocera self also can consume a large amount of dissolved oxygens in water body, be easy to the balance destroying culture-pool water quality, cause water transparence too high, water hypoxia, raising the nose above water to breathe appears in prawn, trip limit and mortality phenomenon, especially when climatic condition such as weather sultry grade is severe, adverse consequences is more serious, whole cultivating pool is even caused to turn over the pool, a large amount of economic losses is produced to aquaculture family.
Therefore, when in cultivating pool, cladocera exists in a large number, removing process must be carried out to cladocera in water body, processing method conventional at present utilizes dredger to carry out manual salvaging, or utilize lamp light trapping salvaging in night, or drug administration is killed, these methods one are that labour intensity is large, need to drop into a large amount of labour costs, two is artificially carry out fishing operation continually, agitation is produced to the prawn being in vegetative stage, directly affect its growth, and the problem being mingled in healthy prawn in cladocera is dragged in generation by mistake; Three is natural water quality conditions that drug administration destroys cultivating pool, the residual cultivation survival rate that directly affects prawn of medicine.In view of this, need to design a kind of simple and feasible, the economical and practical device removing cladocera in prawn culturing pond, to reduce prawn culturing cost and cultivation risk, improve prawn culturing survival rate and success rate.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of device clearing up cladocera in prawn culturing pond, to reduce prawn culturing cost and cultivation risk, improves prawn culturing survival rate and success rate.
To achieve the above object of the invention, provide a kind of device removing cladocera in prawn culturing pond, comprise aerator, fixing rod and gathering unit, fixing rod is arranged between aerator and gathering unit; Described gathering unit comprises framework, the guard on cover framework surface, sack edge are fixed on collecting bag on framework, be fixed on float on framework and rope; The sack of collecting bag is in the face of aerator, rope connecting frame and fixing rod.
Preferably, the bag of described collecting bag is as taper.
Preferably, described framework is rectangle, and described float is arranged on the top thick stick of rectangular frame.
Preferably, described rectangular frame is long is 60cm to 120cm, and wide is 50cm to 80cm.
Preferably, described rope is divided into framework static line and connection cord, and framework static line connects rectangular frame corner and combines in a bit, and connection cord connection combines in the framework static line of any and fixing rod.
Preferably, the bag tail of described collecting bag is porose.
Preferably, described collecting bag bag tail has pricks bag rope.
Preferably, described collecting bag material is nylon bolting silk, has 70 to 120 orders.
Preferably, the mesh of described guard is 30 orders.
Preferably, described aerator and collecting bag sack spacing are 2 to 3 meters.
The device of cladocera in removing shrimp culture pond of the present utility model, be provided with aerator, fixing rod and gathering unit three part, after gathering unit is fixed on fixing rod, aerator starts and forms slow circulating water flow, cladocera in water body can be made with flow, filtered by gathering unit; Because gathering unit adopts structure framework covering guard and fixing collecting bag, prawn is when by gathering unit, can be blocked in outside guard, can not enter in collecting bag, and the cladocera in water body can by the sack of collecting bag, constantly filter in collecting bag, reach the object of collecting and removing prawn culturing pond.
The utility model is a kind of, and to clear up the apparatus structure of cladocera in prawn culturing pond simple, and it is convenient to manufacture, and cost is lower; Easy to operate, the intensity of work is low, is easy to promote the use of in prawn culturing is produced; Avoid a large amount of manual operation of salvaging cladocera and agitation is produced to prawn growth, and avoid medicine and bad reaction is caused to healthy prawn and decreases the pollution to cultivation water environment; Improve the use value of aerator, reduce the consumption of electric energy; Remove cladocera, improve the growing space of dissolved oxygen in pond waters and prawn, avoid prawn and enter in collecting net and produce loss and injured.
