Abstract
The utility model relates to medaka culturing equipment, comprising an aquarium, wherein an artificial fish nest and a floating type fry raising net cage are arranged in the aquarium. The medaka culturing equipment is used for culturing medakas, the medaka culturing equipment has the characteristics of small culturing water body, small pollution, strong culturing controllability, high culturing efficiency, high output, high quality, simple management, convenient fishing operation and the like, and massive standardized experimental animals can be provided for Chinese zoology experiments.
Description
Technical field
The utility model belongs to animal farming industry, is specifically related to a kind of cultivation equipment of medaka.
Background technology
Medaka (O.latipes) belongs to Chordata, Vertebrate, net-rope, bony fish subclass, Medaka shape order, jaw Medaka suborder, Medaka section, Medaka genus.Medaka distributed more widely general can adapt to the weather conditions in the most of area of China, and at the degree of saltiness aqua region in area, river mouth distribution arranged also.
The biological study background of medaka very fully.Medaka is approved by the international organization of majority as a kind of laboratory animal.Because medaka is comparatively responsive to the variation of water quality, is classified as toxicity test the eighties in 20th century by International Standards Organization and one of is planted experimentally.At present, medaka is applied in the multiple water quality monitoring widely.
Yet owing to the pressure of environment damage and species invasion, medaka is fewer and feweri in the distribution of occurring in nature at present.Simultaneously, the source of medaka is still to fish for, and it is less that artificial culture work is carried out, and existing artificial culture mode also exists a series of problems such as output is lower of cultivating simultaneously, and therefore present scale is cultivated and had certain difficulty.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of cultivation equipment of medaka is provided.
The utility model adopts following technical scheme to solve the problems of the technologies described above:
A kind of cultivation equipment of medaka comprises aquarium, establishes artificial fish nest and the floating type net cage of growing seedlings in the aquarium.
The preferred right angle of described aquarium glass aquarium.
Further, described artificial fish nest is provided with a plurality of and is arranged parallel to each other.
Described artificial fish nest comprises the main body of planar structure, and described main body is provided with mesh, and the top of main body is connected with nylon wire, and the bottom of main body is connected with weight.
Further, the described floating type net cage of growing seedlings is provided with a plurality of.
The described floating type net cage of growing seedlings comprises cubical net cage main body, and the top of net cage main body is provided with buoyant module.Owing to be provided with buoyant module, when the water-filling net cage is floating in the aquarium, described floating type is grown seedlings the upper surface of net cage above water, generally requiring the grow seedlings upper surface of net cage and the vertical range of horizontal plane of floating type is 0.1～0.2mm, and this can reach by the material and the volume matching design of buoyant module.
Further, also be provided with water circulation system and Temperature-controlled appliance in the described aquarium.The preferred gas stripping type filter of water circulation system.
Utilize the biochemistry filtered device of gas stripping type to promote water circulation to make the oxygen abundance of aquarium, make it possible to carry out high density, the breed of high water body availability improves water quality simultaneously.
Adopt medaka cultivation equipment of the present utility model to culture medaka, have breeding water body little, pollute little, culture controllability strong, culture efficient height, output and quality height, simple and convenient management, fish for characteristics such as convenient, a large amount of standardization laboratory animal can be provided for the Experiment of Zoology of China.

Embodiment
The cultivation equipment of medaka comprises aquarium 1 as shown in Figure 1, establishes artificial fish nest 2 and the floating type net cage 3 of growing seedlings in the aquarium.
Described aquarium 1 is for being of a size of the 36L right angle glass aquarium of 60cm * 30cm * 20cm.
Further, described artificial fish nest 2 is provided with a plurality of and is arranged parallel to each other.
Described artificial fish nest comprises the main body 21 of planar structure as shown in Figure 2, and described main body is provided with mesh, and the top of main body is connected with nylon wire 22, and the bottom of main body is connected with weight 23.Size of main body is 15cm * 10cm, and mesh size is 30 orders.
Further, the described floating type net cage 3 of growing seedlings is provided with a plurality of.
The described floating type net cage 3 of growing seedlings comprises cubical net cage main body 31, and the top of net cage main body is provided with buoyant module 32.Net cage main body floor space is 90cm
2, height is 30cm, mesh diameter is 0.25～0.28mm.
Further, also be provided with water circulation system 4 and Temperature-controlled appliance 5 in the described aquarium.The preferred gas stripping type filter of water circulation system.
Can adopt following method to utilize the cultivation equipment of medaka of the present utility model to culture medaka:
Screen health, great-hearted medaka kind fish and remove harmful organisms in spring;
The river that injects 2～3 days running water of aeration or filter through sand in aquarium is raised the medaka after the screening in aquarium, and stocking density is 1 tail/L, and female-male proportion is 3: 2; And placement artificial fish nest; In breeding process, maintain the temperature between 22～26 ℃, and throw something and feed every day; With 8 days was the cycle artificial fish nest to be gathered.
The artificial fish nest that takes out is positioned over concentrates hatching in the floating type net cage, temperature is controlled at 28 ± 1 ℃.
The medaka prelarva that hatches uses pulvis feed or artemia nauplii to throw something and feed.
The dissolved oxygen that uses the biochemistry filtered device assurance of gas stripping type water body in whole breeding process guarantees that simultaneously the water body quality is good more than 5mg/L.
Adopt above-mentioned raising method, the medaka survival rate can reach 70%, medaka year output reach 2400 tails/L.
