Description
Technical Field
The utility model relates to the technical field of research on dormant eggs of copepods, in particular to an experimental device for hatching the dormant eggs of copepods.
Background
Copepods are of the phylum Arthropoda, Crustacea, and copepoda. Is a small crustacean with a body length of less than 3mm, and has floating and parasitic life, and is distributed in oceans, fresh water or brackish water, and is one of important groups of animals in water areas. The natural bait can be used as natural bait for a plurality of economic fishes and shrimps, but on the other hand, some zooplankton can prey on larval fish or juvenile fish in a fishpond, so that the natural bait has certain harmfulness to fishery breeding.
Many species in copepods can form dormant eggs after the external environment changes or the population number of the copepods proliferates to a certain value, and the dormant eggs are usually wrapped by thick egg membranes to protect embryos. The dormant eggs are activated after being stimulated by the outside and then hatched into nauplii, wherein two most important factors for stimulating the dormant eggs to hatch are the salinity and the temperature of a water body. Therefore, the influence of water bodies with different salinity and temperature on the incubation of the resting eggs of the copepod is known, and the method has important significance for fish and shrimp culture.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model mainly aims to provide an experimental device for hatching the dormant eggs of copepods, which is convenient for knowing the influence of water bodies with different salinity and temperature on the hatching of the dormant eggs of copepods.
In order to achieve the above object, the present invention provides an experimental apparatus for hatching resting eggs of copepod, comprising: the bearing platform is provided with a plurality of dormant egg hatching containers with openings at the top and a plurality of water containers filled with water with different salinity. The dormant egg hatching container is provided with a water inlet and a water outlet, the water container is provided with a water drainage hose, and the other end of the water drainage hose can be connected with the water inlet. Each dormant egg hatching container is provided with a heating wire for adjusting the water temperature in the dormant egg hatching container, and the bearing platform is provided with a controller for controlling the heating of the heating wire. The bearing platform is further provided with a support, a microscope is arranged on the support in a sliding mode and is located right above the dormant egg hatching containers.
Preferably, the bearing platform is in a step shape, and the plurality of water containers are all higher than the plurality of dormant egg hatching containers.
Preferably, the water inlet is higher than the water outlet, and the water inlet and the water outlet are both provided with a first switch valve.
Preferably, the drainage hose is provided with a connector, the connector is connected with the water inlet, and the connector is provided with a second switch valve.
Preferably, the side wall of the dormant egg hatching container is provided with an embedding groove in a surrounding mode, and the electric heating wire is arranged in the embedding groove.
Compared with the prior art, the utility model has the beneficial effects that: the whole structure is simple, the manufacture is easy, the use and the observation are very convenient, and the reliability of the experimental result is high.
