Raising device for crustacean plankton

Abstract

The invention discloses a raising device for crustacean plankton. The raising device comprises a feed culture room, a raising substrate storage chamber, a female crustacean plankton raising chamber, a young crustacean plankton raising chamber, a return chamber and a power system. The female crustacean plankton raising chamber and the young crustacean plankton raising chamber are transparent glass cylindrical containers. An aspen resin layer is connected to the inner wall of the bottom conical part of the young crustacean plankton raising chamber. The pipeline end of one end, connected with and extending into the young crustacean plankton raising chamber, of the female crustacean plankton raising chamber is connected with a vertical glass tube connected with the atmosphere. The return chamber is a transparent glass cylindrical container with a conical bottom. The top of the raising substrate storage chamber is as high as the return chamber. The raising device has the advantages the crustacean plankton raised by the device is healthy and free of germs, mechanical automatic running water type raising is achieved, manpower is saved, and cost is lowered greatly.

Description

technical field [0001] The present invention relates to a breeding device for planktonic crustaceans. Background technique [0002] The planktonic crustaceans in the prior art have become model organisms widely used in laboratories at home and abroad because of their short growth cycle, fast growth, high reproductive capacity, easy cultivation, and sensitivity to water environment stress. It plays an important role in the testing of acute and chronic toxicity and environmental hormone effects. [0003] At present, many international organizations and countries such as Europe, the United States, Japan, South Korea and my country have formed a systematic standard method for toxicological testing of planktonic crustaceans. This method has clear requirements for the age, culture medium, and culture conditions of the planktonic crustaceans used in the test. However, most laboratories in my country currently lack effective equipment or devices for planktonic crustaceans, and can...

AI Technical Summary

Problems solved by technology

However, most laboratories in my country currently lack effective equipment or devices for planktonic crustaceans, and can only rely on manual operations, which is not only inefficient and heavy workload, but also difficult to obtain young planktonic crustaceans of a specific age required for experiments. It brings certain difficulties and large errors to the detection work
