Abstract
The utility model relates to a bag-type larva collector which comprises a net cylinder. A fish body temporary rearing area is arranged inside the net cylinder. A conical colleting bag used for collecting larva cysts is detachably connected with the bottom of the net cylinder. When the bag-type larva collector is used, the bag-type larva collector is placed in seawater, firstly fishes are reared in the net cylinder, fish bodies can freely move around in the fish body temporary rearing area, then infective stage larvae are placed into the fish body temporary rearing area, the larvae continuously grow up after infecting the fish bodies, then the larvae are separated from the fish bodies, the fallen cysts slide into the conical collecting bag, and the conical collecting bag is full of the cysts. When the cysts need to be collected, the conical collecting bag is taken out of the surface of the seawater, sediment is conveniently taken out, and therefore the cysts of cryptocaryon irritans brown are collected under the condition that the fish bodies are not influenced.
Description
Technical field
The utility model relates to a kind of pocket type polypide gatherer.
Background technology
Stimulating cryptonucleus insect is a kind of epizoon of seawater fish, how it is carried out immune protection in order to study, and we need collect the packing of a large amount of stimulation cryptonucleus insects, and the diameter of polypide packing is between the 0.1-0.5 millimeter.Stimulate the packing workload of cryptonucleus insect big owing to collect in water body, collection work can influence the activity of fish body in water, and polypide is difficult for observing and collects, and therefore is necessary to design a kind of gatherer of being convenient to collect the polypide packing.
The utility model content
The utility model is made improvement at the problem that above-mentioned prior art exists, and namely the technical problems to be solved in the utility model provides a kind of convenient pocket type polypide gatherer of collecting the polypide packing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of pocket type polypide gatherer, comprise the net tube, and be that the fish body is supported the district temporarily in the described net tube, the bottom of described net tube is removable to be connected with for the cone-shaped collection bag of collecting the polypide packing.
Further, described net tube is to be sewed up by skeleton and net sheet to form.
Further, the mesh order number of described net tube is 120 orders.
Further, the material of described skeleton is stainless steel.
Further, the top of described cone-shaped collection bag is connected by the bottom of first slide fastener with the net tube.
Further, described cone-shaped collection bag is made up of taper etting and collecting bag, and the bottom of described taper etting is connected with collecting bag by second slide fastener.
Compared with prior art, the utlity model has following beneficial effect: this pocket type polypide collector structure is simple, cost of manufacture is low and easy to use, conveniently culture the fish body and infect the fish body with polypide in the net tube, conveniently the cone-shaped collection bag being taken out the water surface stimulates the cryptonucleus insect packing to collect under the situation that does not influence the fish body.
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Among the figure: 1-nets tube, and 11-skeleton, 12-net sheet, 2-cone-shaped collection bag, 21-taper etting, 22-collecting bag, 3-first slide fastener, 4-second slide fastener, A-fish body are supported the district temporarily.
Embodiment
As shown in Figure 1, a kind of pocket type polypide gatherer comprises net tube 1, is that the fish body is supported district A temporarily in the described net tube 1, and the bottom of described net tube 1 is removable to be connected with for the cone-shaped collection bag 2 of collecting the polypide packing.
In the present embodiment, described net tube 1 is to be sewed up by skeleton 11 and net sheet 12 to form, and the mesh order number of described net tube 1 is 120 orders, namely adopts 120 order net sheets, and the material of described skeleton 11 is stainless steel.
In the present embodiment, described cone-shaped collection bag 2 is made up of taper etting 21 and collecting bag 22, the upper shed of described taper etting 21 is bigger than under shed, the top of described cone-shaped collection bag 2 is connected by the bottom of first slide fastener 3 with net tube 1, the top that is taper etting 21 is connected by the bottom of first slide fastener 3 with net tube 1, and the bottom of described taper etting 21 is connected with collecting bag 22 by second slide fastener 4.
During use, this pocket type polypide gatherer is placed in the seawater, cultured fishes in roomy net tube 1 earlier, the fish body can be supported district A temporarily at the fish body and freely be moved about; Put into infective stage larva again, polypide constantly grows up after infecting the fish body, breaks away from the fish body subsequently, and the packing that drops is slipped in the cone-shaped collection bag 2 of net tube 1 bottom, enrichment packing in cone-shaped collection bag 2.When needs are collected packing, draw back first slide fastener 3 earlier so that cone-shaped collection bag 2 is taken out the water surface, draw back second slide fastener 4 again so that collecting bag 22 is separated with taper etting 21, the convenient taking-up precipitated, and stimulates the cryptonucleus insect packing thereby collect under the situation that does not influence the fish body.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
