Problems solved by technology

Among them, the culture in small water bodies is generally cultured in beakers or glass tanks, which are often used for small-scale experiments, which cannot satisfy a large number of experiments and be used as materials for breeding live bait; while the culture in large outdoor ponds is a kind of extensive culture, there are some problems in production and application. The problem is that there are many factors that are difficult to control (such as increased rainfall, etc.) that are prone to decline in the output of copepods and increased mortality, which makes their output unstable and insufficient supply, which directly affects the cultivation of fish seedlings, etc.

Embodiment Construction

[0008] This cultivating device has a set of bucket type incubator 16, and it can be used for copepod adults to lay eggs and ovum hatches and larva growth and development; The water outlet of cooler 11 is communicated, and the water outlet at the bottom of the incubator is communicated with filter box 8 by water pipe, and the outlet pipe of incubator 16 is equipped with harvest port 18, and filter screen 17 is equipped with at the inner barrel bottom of incubator. There is a box cover 5 on the filter box 8, which mainly plays the role of dust prevention; there are two orifice plates 6 inside, which divide the box body into three parts, and the two parts on the left side are equipped with different filter materials to filter the water for cultivation. , Cleaning effect. Also on the pipeline between filter case 8 and cooler 11, water pump 9, ultraviolet sterilizer 7 and heater 4 are successively housed. The water pump 9 provides power for the circulation of water in the device. ...

Abstract

A sleeved drum type culturing apparatus for the copepodid crustacean is composed of a culturing drum with internal and external drums, water inlet and outlet and internal net filter, an air-water mixer, a cooler, a water pump, an ultraviolet disinfector and a heater with external sensor.

Description

technical field [0001] The invention relates to a device used in aquaculture, in particular to a cultivation device and its application in the cultivation of crustacean copepods. Background technique [0002] At present, the culture of crustacean copepods is generally cultivated in small indoor water bodies and outdoor large ponds, and there is no copepod culture device. Among them, the culture in small water bodies is generally cultured in beakers or glass tanks, which are often used for small-scale experiments, which cannot satisfy a large number of experiments and be used as materials for breeding live bait; while the culture in large outdoor ponds is a kind of extensive culture, there are some problems in production and application. The problem is that there are many factors that are difficult to control (such as increased rainfall, etc.) that are prone to decline in the output of copepods and increased mortality, making their output unstable and insufficient supply, whi...
