Abstract
The utility model discloses a closed circulating water culturing device for the fish larval experiment, which relates to the closed circulating water culturing device for the fish experiment in the fish larval stage. The utility model has the purpose to provide the closed circulating water culturing device for researching the fish larval, and the structure is simple, the operation is easy, the environment factors influence in each experimental group can be eliminated thoroughly, and the uniformity and the repeatability of the experimental conditions are ensured, which required in the utility model. The utility model adopts the technical proposal that the utility model is composed of a water storage tank, a filtrating device, a water inlet pipe, an aquatic tank, a water pump, a water outlet pipe, and experiment vessels. The utility model has characteristics that the water inlet pipe is connected with the water storage tank and the aquatic tank, the water outlet pipe of the aquatic tank is connected into the filtrating device through the water pump, the filtrating device is positioned on the water tank, and the experiment vessels are hung in the aquatic tank. The utility model is used for the fish larval culturing experimental device in the aquaculture.
Description
Technical field:
The utility model belongs to fish experiment alevin stage cultivator.
Background technology
Fish belong to aquatic animal, and lot of experiments need be carried out in water body.Fish physiology, research work such as grow need be experiment material with the live fish, culture for a long time in water.In this class research, grow needed primary condition except satisfying fish growth, beyond water temperature, dissolved oxygen etc., importantly require the uniformity of experiment condition, guarantee the contrast property and the repeatability of experiment.This class research need be carried out in flowing water or circulating water culture system for this reason.Flowing water or circulating water culture system device all comprise storage tank, water plant, aquarium.
The fish prelarva is generally less, the method that the culture experiment device of fish prelarva is commonly used has 2 kinds: the one,, newly hatched larvae is directly put into nursery pond to be cultivated, therefrom Related Experimental Study is carried out in sampling, these class methods are suitable for the cultivation technical research of fish prelarva, be applied to fish individual growth growth research but be unsuitable for, and experiment is repeatable relatively poor; The 2nd,, newly hatched larvae is put into the small dimension aquarium or beaker carries out grouping experiment, but the influence of this method envirment factor is bigger, can't guarantee the uniformity of experiment condition.
The utility model content
The purpose of this utility model is to provide a kind of closed circulation water cultivator that is used for the research of fish prelarva, this matching requirements is simple in structure, easy to operate, can thoroughly eliminate the envirment factor influence of each experimental group, guarantee the uniformity and the repeatability of experiment condition.
The technical solution of the utility model adopts storage tank, filter, water inlet pipe, aquarium, water pump, outlet pipe, experiment container to constitute, it is characterized in that water inlet pipe links to each other with aquarium with storage tank, the aquarium outlet pipe inserts filter through water pump, filter places on the storage tank, and experiment container hangs in the aquarium.
The utility model compared with prior art, have the following advantages and effect: simple in structure, easy to make, can guarantee the uniformity of experiment condition in each experiment container, cost is low, the conserve water resource is applicable to the indoor closed circulation water culture experiment of fish prelarva system.
Description of drawings
What accompanying drawing was represented is the closed circulation water cultivator schematic diagram that is used for the prelarva experiment.
Embodiment
This device (seeing accompanying drawing) comprises storage tank 1, water inlet pipe 2, aquarium 3, outlet pipe 4, water pump 5, filter 6, experiment container 7, experiment container suspension board 8; Wherein, the filter course of filter 6 is made up of sponge filter course 6a, fine sand filter course 6b, coarse sand filter course 6c, nylon yarn thin,tough silk filter course 6d, porose dividing plate 6e; Water inlet pipe 2 links to each other with aquarium 3 with storage tank 1 respectively, guarantees the water body exchange in storage tank 1 and the aquarium 3; In the middle of the water inlet pipe 2 control valve 2a is housed and is used to regulate the current size; Outlet pipe 4 one ends link to each other with the aquarium bottom, and an end pumps into filter 6 by water pump 5 with the water in the aquarium, and filter 6 places on the storage tank 1, enters storage tank 1 through the water that filters.Control water body exchange rate between aquarium 3 and the storage tank 1 by the size of control of pump water outlet, filter, remove solid particle and oxious component in the water body, guarantee that water body recycles by the water body in 6 pairs of aquariums of filter.The bottom of experiment container 7 is the end that bolting silk is made, and mesh size is made according to the size of experiment prelarva, guarantees that water in each experiment container 7 and water in the aquarium 3 lead to, and the environmental condition in each experiment container all has uniformity like this; 7a at the bottom of the threaded bolting silk button of experiment container 7 employings can conveniently change according to the size of experiment fish.Experiment container 7 container suspension board 8 by experiment hangs in the aquarium 3.
Claims (3)
1. prelarva is tested the closed circulation water cultivator of usefulness, adopt storage tank, filter, water inlet pipe, aquarium, water pump, outlet pipe, experiment container to constitute, it is characterized in that water inlet pipe links to each other with aquarium with storage tank, the aquarium outlet pipe inserts filter through water pump, filter places on the storage tank, and experiment container hangs in the aquarium.
2. the closed circulation water cultivator of prelarva according to claim 1 experiment usefulness is characterized in that the end that the bottom of experiment container adopts bolting silk to make.
3. prelarva according to claim 1 is tested the closed circulation water cultivator of usefulness, it is characterized in that the experiment container bottom is at the bottom of the threaded bolting silk button.
