Research on Swimming Behavior and Metabolism of Fish Swimming Lane Series

Research on Swimming Behavior and Metabolism of Fish Swimming Lane Series

The fish swimming behavior metabolism measurement lane series is an integrated scientific research equipment that synchronously measures the oxygen consumption rate (MO ₂) and swimming ability of aquatic organisms (mainly fish) in swimming state. It can synchronously measure swimming speed and oxygen consumption rate, calculate critical swimming speed (Ucrit), maximum metabolic rate (MMR), aerobic metabolic range (Aerobic Scope), and post exercise excess oxygen consumption (EPOC).

Fish Swimming Respiratory Metabolism Measurement System DAQ-BT

Feature Introduction

The system mainly includes a swimming pool, underwater monitoring sensors, and a real-time monitoring and analysis software system. This monitoring system can be used for on-site measurement of swimming ability of captured fish in the wild, including respiratory metabolism, behavioral characteristics, etc. After years of research and laboratory use, this system has stable and reliable performance, and can be used to measure the physiological functions, kinetic energy, behavior, biomechanics, and kinematics of swimming fish.

principle

The system can control the flow velocity of the fluid, making it convenient for researchers to test and study different flow fields of fish. And there is a flow velocity sensor probe that accurately records real-time flow velocity. Fiber optic dissolved oxygen sensors can simultaneously measure the oxygen content of water bodies. By connecting to a computer and supporting software, the oxygen consumption of fish can be calculated, and intuitive two-dimensional curve graphs can be drawn for easy experimental results.

The photography system can record the behavior of fish and draw activity curves through software, which can more reasonably study the behavioral characteristics of fish under changing flow fields.

Swimming respiration measurement of small organisms

The smallest "Blazka type" swimming tunnel, 170mL and 1500mL. Usually used for swimming metabolism/performance testing of individual small fish (such as adult zebrafish, medaka, medaka, stingray, etc.).

Testing section of swimming sink：Located inside an inner glass tube surrounded by an outer glass tube. Detachable plugs facilitate quick insertion or removal of fish. The swimming chamber is placed in a constant temperature water bath to control temperature and regulate water quality.

external motorControlled by the motor control box. The motor control box is connected to the DAQ-BT instrument, which is connected to Autorsp via Bluetooth ™ 3 software for wireless connection. Automated control of water flow rate through software (e.g. through pre-set programs), without causing interference to animals during the experimental process.

submersible pump：The water pump is placed in the water bath and connected to the flushing inlet of the swimming cabin. Flush the outlet to ensure continuous replenishment of water in the swimming compartment during the swimming test. The submersible flushing pump is connected to the PowerX4 four-way power socket and supports software driven device switch control and monitoring through wired LAN/Ethernet or wireless Bluetooth. This can be done through AutoResp ™ Implement independent water pump control.

Optical dissolved oxygen probeThe built-in immersion oxygen probe can be installed in the testing section for non-invasive optical oxygen measurement. The high-precision oxygen measuring instrument Witrox supports wireless Bluetooth communication and can collect dissolved oxygen data from inside the swimming chamber. The high-precision PT1000 temperature sensor provides real-time temperature compensation for oxygen data, ensuring measurement accuracy.

After completing the calibration in DPTV2 software, simply load the exported calibration file into Autorsp ™ 3 of them can be put into use immediately.

Witrox, DAQ-BT, and PowerX4 can be connected to AutoResp on your PC via Bluetooth (or LAN) ™ 3. Therefore, you can place the PC in a separate room away from the water source and directly access AutoResp ™ 3. Conduct in-depth data collection and analysis.

Large scale biological swimming respiration measurement

The specification range of large swimming tunnel models is between 5L-850L. These swimming tunnels are mainly made of acrylic material and are commonly used to evaluate swimming performance (critical swimming speed) and determine the maximum metabolic rate of individual fish. They are suitable for wet weight ranges from 20g-15kg and can even be used for fish swarm/population studies of small fish.

The following is a weight table of the research objects corresponding to the capacity

Power supply: 230V/50Hz European standard, 110V/60Hz American standard

The testing section of the swimming sink is located on the side of the sink, which allows unobstructed observation of experimental animals and is very suitable for filming or visualizing water flow. The testing section is equipped with a detachable spiral top cover for easy insertion or removal of animals. If you need quick access to experimental organisms (such as zebrafish populations), consider using a quick detachable cover.

The swimming cabin is installed inside the water bath device for temperature control and water quality regulation. The entire swimming cabin is detachable for easy cleaning and maintenance.

The swimming tunnel is equipped with a high-power external motor controlled by a variable frequency drive (i.e. motor control box). This motor control box is connected to the DAQ-BT instrument

Submersible water pumpPlaced inside the sink and connected to the flushing inlet of the swimming pool. Ensure that the water in the swimming pool is continuously replenished during the swimming test by flushing the outlet.
