Product Description

        The aquatic organisms forced swimming respiratory metabolism measurement system is used for the swimming ability test of aquatic organisms, exercise respiratory metabolism (respiratory oxygen consumption) measurement, resting metabolism measurement and other functions. It is an important research instrument to carry out the ecology of fish and other aquatic organisms, water environment toxicology, aquaculture, fish  physiological ecological behavior, aquatic animal development ecology and other aspects.

Metabolic chamber has multiple specifications, suitable for different sizes of fish, from zebrafish swimming fish to large fish, chamber sizes from 170ml~800L.

 Applied disciplines: Marine Biology, Pharmacology, Animal Behavior, Eco-hydraulic Engineering, Dam Fish Research, Metabolism, Medicine, Aquatic Breeding, Molecular Biology

Product Characteristics

l A swimming respiratory measurement system designed for aquatic organisms

l Measure respiratory metabolism during forced movement state (forced-swimming)

l Fully automatic-control

l In-depth analysis, statistics, and data export

l High-throughput experiments can be conducted, and different sizes of swimming tunnels can be selected

l fresh water and sea water are both applicable

l Measurement and analysis of the real-time oxygen consumption rate

  The system provides the test function of the swimming ability of fish. The system adjusts the impeller speed through the voltage input of the motor control box, so as to create the swimming area at different flow rates. The design has the advantages of flexible control for efficient experiments, and highly restore natural flow field.

The observation of behavioral movement mechanism of aquatic organisms in different environmental states is feasible using an down-view camera. It can help the experimenter to conduct in-depth analysis of the research directions including feeding, biological social interaction research, swimming rule, behavior trajectory, avoidance ability and so on.

The respiratory metabolism measurement system for aquatic organisms is mainly used to measure oxygen consumption in fish, aquatic invertebrates, fish eggs and their embryos， and even plankton. It is widely used in the ecology of aquatic life, water environment toxicology, aquaculture, fish behavior physiological ecology, aquatic animal development ecology and aquarium.

The respiratory metabolic measurement system for aquatic organisms adopts “intermittent”respiratory measurement method, which combines the advantages of “open” respiratory measurement method with long measurement time and simple “closed” respiratory measurement method, overcoming the disadvantages of  poor time resolution in “open”mode and poor continuous measurement in “closed”mode.

       Characteristics

l  “Intermittent”respiratory measurement method, which combines the advantages of “open” respiratory measurement method with long measurement time and simple “closed” respiratory measurement method, overcoming the disadvantages of  poor time resolution in “open”mode and poor continuous measurement in “closed”mode.

l Dissolved oxygen measurement: Fluorescent fiber oxygen measurement technology, high measurement accuracy, strong stability, no oxygen consumption;

l Respiratory measurement chamber has a static respiratory chamber and a dynamic respiratory chamber / swimming chamber, which are used to measure the standard metabolism (SMR) and the activity metabolism (AMR) at different swimming speeds respectively;

l Fully automatic control, recording and analysis of data, simple and easy to use; the control of submersible pump and the acquisition of oxygen signal are through Bluetooth. Remote wireless transmission can effectively avoid the complicated cabling connection and the working noise caused by submersible pump.

l Respiratory chamber is highly customized in wither shapes, ans sizes according to the type of aquatic animals.

l  Water environment control module: including temperature monitoring control module and dissolved oxygen monitoring control module. Can individually regulate CO₂ / pH.

a. The temperature monitoring and control module includes the temperature sensor, submersible pump, stainless steel cooling pipe, etc. Temperature sensor Pt1000 measurement range -50℃ ~180℃, accuracy ± 0.15℃;

b. The oxygen monitoring and control module includes fluorescent fiber oxygen sensor, solenoid valve, air stone, etc. The module controls the solenoid valve to add oxygen or nitrogen to control the water in the state of hyperoxia or hypoxia.

c. CO₂ / pH monitoring and control module includes controller host, pH meter and probe, solenoid valve, air stone and CapCTRL control software, etc. By monitoring pH value, the CO₂ content in water is indirectly determined and the pH and CO₂ content of control water is adjusted and monitored in real time. The pH measurement range is 0~14 and the resolution is 0.01.
