Abstract
The utility model discloses a net cage for cultivating ancherythroculter nigrocauda with a small water body. The net cage is used for experimental study and comprises a net cage body (1) without a top cover, and a net piece (2) which is a little larger than the net cage body (1). The net piece (2) and the net cage body (1) are sewn together. The net piece (2) covers the most upper top of the net cage body (1). A gap (5) is reserved on the front section of the top cover of the net cage body (1), so that convenience is brought to fodder throwing and test observation. The net cage enables a test to be accurate, materials are easy to take, the manufacturing cost is low, scientific research personnel can carry out small water body cultivation tests conveniently, and the net cage has the great advantage compared with a water circulating system often used for the experimental study.
Description
Technical field
The utility model relates to a kind of net cage, particularly the net cage of a kind of nearly red Culter of little aquifer cultivation black tail for experimental study.
Background technology
At present, the medium and small aquifer cultivation test of aquaculture, generally adopts indoor full automatic circulation.Because full-automatic water circulatory system cost is high, a lot of scientific research institutions only have one or two covers, and causing a lot of students and scientific research personnel to do this type of test needs to queue up, and the slightly nervous prefecture-level scientific research institutions of funds do not have enough funds to buy above-mentioned circulation device.In addition, for this fiddle-footed fish of the nearly red Culter of black tail, as adopt traditional net cage to carry out little aquifer cultivation test, fish easily jump out net cage, ingest inactive, even do not ingest, and cause test to carry out.
Utility model content
In order to overcome the above-mentioned deficiency that has technical problem, the utility model provides the net cage of a kind of nearly red Culter of little aquifer cultivation black tail for experimental study.
Technical solution adopted in the utility model is: the net cage of the nearly red Culter of a kind of little aquifer cultivation black tail, it is characterized in that, and comprising: half-headed net cage (1); The net sheet (2) slightly larger than net cage (1); Net sheet (2) is stitched together with net cage (1), net sheet (2) hides most of net cage (1) upper top, stay a space (5) at net cage (1) upper top cover leading portion, instant feedstuff is thrown something and fed and experimental observation.
Further, by the six roots of sensation stretching (3) at top and four sinkers (4) of net cage bottom, package unit is fixed in the little water body of indoor and outdoor.
Further, net cage and net sheet are made up of 40 object summer flower screen cloths.
Further, net cage length is 0.8 meter, net sheet length and width is respectively 1.6 meters, 0.8 meter, and the gap length that net cage and net sheet leave after sewing up is 0.3 meter, and the width that net sheet covering net cage rear left and right, rear have more is respectively 0.4 meter, 0.4 meter, 0.3 meter.
The utlity model has following positive effect:
Compared with traditional net cage, tradition net cage is open type, the utility model is added a cover a slightly larger net sheet can be for experimenter be in the little water body environment of indoor and outdoor, nearly red Culter is this frightening for cultivation black tail, easily frightened, the fish that irritability is strong, strengthen its safety, avoid fish to jump out net cage, can guarantee that they ingest enthusiastically, thereby make test more accurate, reduce in process of the test, because the nearly red Culter of black tail is subject to the artificial interference experimental error causing of stopping eating, net sheet is larger than the area at net cage top, make the fish in net cage can be in more quiet environment, be not subject to interference around.And, the material that this device adopts is 40 order net cages of modal green nylon wire braiding, draw materials simple, cheap, greatly facilitate scientific research personnel and carry out little aquifer cultivation test, there is very large advantage with respect to the water circulation system that is usually used in experimental study.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For example the utility model is explained in more detail below in conjunction with accompanying drawing:
As shown in Figure 1, it shows a kind of net cage for the nearly red Culter of the little aquifer cultivation black tail of experimental study, comprises half-headed net cage 1, and net cage 1 hides a slightly larger net sheet 2, and net cage 1 and net sheet 2 are sewed up, and stays space 5 instant feedstuffs to throw something and feed and experimental observation.
Unnecessary area is left at the rear, left and right of net sheet 2, by the six roots of sensation stretching 3 at top and four sinkers 4 of net cage bottom, package unit is fixed in the little water body of indoor and outdoor.
Net cage and net sheet are made up of 40 object summer flower screen cloths.
In specific implementation process, the net cage length that the utility model is recorded is 0.8 meter, net sheet length and width is respectively 1.6 meters, 0.8 meter, the gap length that net cage and net sheet leave after sewing up is 0.3 meter, and net sheet hides its width left and right, that rear has more of net cage and is respectively 0.4 meter, 0.4 meter, 0.3 meter.
Above disclosed is only preferred embodiments of the present utility model, can not limit with this interest field of the utility model, and the equivalent variations of doing according to the utility model claim, still belongs to the scope that the utility model is contained.
Claims (4)
1. a net cage of the nearly red Culter of little aquifer cultivation black tail, is characterized in that, comprising: half-headed net cage (1); The net sheet (2) slightly larger than net cage (1); Net sheet (2) is stitched together with net cage (1), and net sheet (2) hides most of net cage (1) upper top, stays a space (5) at net cage (1) upper top cover leading portion.
