Abstract

The invention relates to an automation running-water type cultivation device of daphnia magna. The device comprises six components including a feed culturing room, a cultivation ground substance storage room, a female daphnia feeding room, a young daphnia feeding room, a return room and a power system, wherein water outlet tubes at bottoms of the feed culturing room and the cultivation ground substance storage room are connected with the female daphnia feeding room through the power system; a water outlet tube at the bottom of the female daphnia feeding room is connected with the top of the young daphnia feeding room; a water outlet tube on the top of the young daphnia feeding room is connected with the top of the return room; and a water outlet tube at the bottom of the return room is connected with the cultivation ground substance storage room.

Description

technical field [0001] The invention belongs to the field of plankton culture, and in particular relates to an automatic flowing water culture device for large daphnia. Background technique [0002] Daphnia magna Straus belongs to Arthropoda, Crustacea and Cladocera. It is a common planktonic crustacean and an indispensable component in the freshwater food chain. Because of its short life cycle, fast growth, high reproductive capacity, easy cultivation, and sensitivity to water environment stress, it has become a model organism widely used in laboratories at home and abroad. Plays an important role in testing. [0003] At present, many international organizations and countries such as OECD, European Union, the United States, Japan, South Korea and my country have formed systematic standard methods for toxicological testing of Daphnia magna. This method has clear requirements on the age, culture medium and culture conditions of Daphnia magna used in the experiment. However...
