Abstract
The invention discloses a kind of cultural method for promoting Daphnia magna growth and breeding, including following operating procedure：1) using green alga as food source culture Daphnia magna, a green alga is replaced per 48h；2) water temperature is controlled in incubation as 18~28 DEG C, it is 7.6~8.0 to control culture water pH value；3) young Magna in incubation is separated into carry out squamous subculture in time.The present invention substantially increases the growth and breeding ability in Daphnia magna incubation, shortens cultivation cycle, and then effectively improve the economic benefit of Daphnia magna culture by improving the cultural method of Daphnia magna.Daphnia magna can be tamed to adapt it to the water body environment of certain green alga density simultaneously, can reach Effect of Ecological Restoration by ingesting planktonic algae so that the later stage is put into eutrophication water.
Description
Technical field
The present invention relates to water ecologies to repair field, more particularly to a kind of cultural method of Daphnia magna.
Background technology
The research that current biological treatment technology repairs aquatic ecosystem has become hot spot.And biomanipulation also becomes
The development trend of eutrophied water treatment mainly takes the photograph plankton feeder by removal or reduces plankton feeding habit fish
Quantity increases the biomass of zooplankter, and filter is promoted to eat the growth of efficient phytophagous macrozooplankton, floating so as to improve
Move about feed efficiency of the object to phytoplankton, the final biomass for reducing phytoplankton.
A kind of Daphnia magna macrozooplankton common as lake, reservoir, its growth, reproduction speed are fast, during sociales
Between it is long, there are stronger potentiality of ingesting, it is expected to according to bio operon principle, it is excessive to reach control eutrophication water phytoplankton
The purpose of growth, however.Wherein growth and breeding culture efficiency of the Daphnia magna before water body is launched is particularly important, how by effective
Cultural method obtain the fast Daphnia magna of growth and breeding speed, become the pass that Daphnia magna is applied to water ecology repairing and treating
Key.
The content of the invention
It is an object of the present invention to provide a kind of cultural methods that may advantageously facilitate Daphnia magna growth and breeding, can be effective
Ground improves the growth and breeding ability in Daphnia magna incubation, greatly shortens incubation time.
The technical solution used in the present invention is：A kind of cultural method for promoting Daphnia magna growth and breeding, including as follows
Operating procedure：
1) using green alga as food source culture Daphnia magna, a green alga is replaced per 48h；
2) water temperature is controlled in incubation as 18~28 DEG C, it is 7.6~8.0 to control culture water pH value；
3) young Magna in incubation is separated into carry out squamous subculture in time.
As being further improved for said program, the step 2) incubation light intensity be 1000~1250kx, brightness
Than for 14h:It is carried out under the external environment of 10h.
As being further improved for said program, the step 1) green alga is chlorella or scenedesmus.Specifically, chlorella and
Scenedesmus is respectively provided with better outdoor environment simulation effect, can effectively improve adaptability of the Daphnia magna to outdoor water body environment.
As being further improved for said program, the chlorella is 1.8 × 10 in the density of culture water body6~2.2 ×
106A/ml, the scenedesmus are 4 × 10 in the density of culture water body5~5 × 105A/ml.Specifically, nutrition water body green algae is close
Degree defines the efficiency ingested beneficial to raising Daphnia magna.
The beneficial effects of the invention are as follows：The present invention substantially increases Daphnia magna training by improving the cultural method of Daphnia magna
Growth and breeding ability during supporting, shortens cultivation cycle, and then effectively improves the economic benefit of Daphnia magna culture.It simultaneously can
The water body environment of certain green alga density is adapted it to tame Daphnia magna, put into eutrophication water can so as to the later stage
By ingesting planktonic algae to reach Effect of Ecological Restoration.

Than for 14h:It is carried out under the external environment of 10h.
Preferred embodiment is further used as, the step 1) green alga is chlorella or scenedesmus.Specifically, chlorella and
Scenedesmus is respectively provided with better outdoor environment simulation effect, can effectively improve adaptability of the Daphnia magna to outdoor water body environment.
Preferred embodiment is further used as, the chlorella is 1.8 × 10 in the density of culture water body6~2.2 ×
106A/ml, the scenedesmus are 4 × 10 in the density of culture water body5~5 × 105A/ml.Specifically, nutrition water body green algae is close
Degree defines the efficiency ingested beneficial to raising Daphnia magna.
Above-described embodiment is the preferred embodiment of the present invention, all with similar technique of the invention and the equivalence changes made,
The protection category of the present invention should all be belonged to.
