In one preferred embodiment of the utility model, the water body is river, lake or pond.
In one preferred embodiment of the utility model, under cultivating condition, demarcation strip on flashboard is by culture zone and acquisition
It separates from Daphnia magna cannot traverse to enrichment region from culture zone.
In one preferred embodiment of the utility model, the wave-length coverage of the light source is 460nm-470nm.
The another technical solution that the utility model uses for：A kind of side carrying out Daphnia magna acquisition in breeding spaces
Method includes the following steps：
S1 lights the light source in enrichment region, the hood expansion of culture zone is sheltered to the periphery of culture zone, by flashboard
On demarcation strip detach out, so that Daphnia magna is travelled freely through grid；
S2 is placed in food bait on the fibrous layer into enrichment region；
Enrichment plate is detached enrichment region and is transferred in collecting pit by S3.
In one preferred embodiment of the utility model, the step S2 duration is -150 minutes 15 minutes.
In one preferred embodiment of the utility model, every 15 to 30 minutes, it is placed in a food bait.
The utility model solves defect present in background technology, and the utility model has following advantageous effect：
(1) Daphnia magna is cultivated in nature environment, Daphnia magna is cultivated in culturing area by the form of net cage,
Net cage is mutually isolated by the Daphnia magna inside and outside it, prevents from intersecting the pure of breeding influence Daphnia magna type.Net cage can not simultaneously
The disconnected water body with nature carries out inside and outside exchange, ensures that the growing environment of Daphnia magna is substantially consistent with the Daphnia magna of nature,
Initial resistance to malicious ability is coincide substantially with nature.
(2) enrichment region can lure Daphnia magna to realize that the enrichment of Daphnia magna is harvested by light and food bait, while
The separation of Daphnia magna and cultivation raising object more mixed and disorderly in culture zone is realized, the Daphnia magna of acquisition is cleaner, eliminates
The step of great effort removes the impurity dirt of incoming call is expended after acquisition.
(3) it is enriched with the fibrous layer being arranged on plate and provides the carrier of enrichment absorption for Daphnia magna, and plate will be enriched with from water
In Daphnia magna can be prevented to be detached from enrichment plate when detaching.Area source can attract Daphnia magna to move about to enrichment region.
(4) hood corresponding light source is arranged, and the condition of being protected from light is provided for culturing area, and the light source for setting off by contrast enrichment region is made
With guarantee enrichment region and culture zone light condition contrast are bigger, embody the effect that light lures Daphnia magna as far as possible.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples；
Fig. 1 is the schematic top plan view under cultivating condition of the preferred embodiment of the utility model；
Fig. 2 is the schematic top plan view under acquisition condition of the preferred embodiment of the utility model；
In figure：1, culture zone；2, enrichment region；3, hood；4, demarcation strip；5, grid；6, area source；7, fibrous layer.
Specific implementation mode
The utility model is described in further detail presently in connection with drawings and examples, these attached drawings are simplified
Schematic diagram only illustrates the basic structure of the utility model in a schematic way, therefore it only shows structure related with the utility model
At.
As depicted in figs. 1 and 2, a kind of breeding spaces convenient for acquisition Daphnia magna, including：The culture zone separated by flashboard
And enrichment region, which is characterized in that enrichment region is provided with enrichment plate and light source, is enriched on plate and is provided with fibrous layer, culture zone setting
It includes the demarcation strip being close together and grid to have the hood that can be folded, flashboard, and Daphnia magna can travel freely through the net of grid
