Key Event Description
Adequate swimming performance in fish is essential for behaviour such as foraging, predator avoidance and reproduction.
How It Is Measured or Detected
For fish larvae, automated observation and tracking systems are commercially available and increasingly used for measuring swimming performance including distance travelled, duration of movements, swimming speed, etc. This kind of measurements is often included in publications describing effects of chemicals in zebrafish larvae (Hagenaars et al., 2014; Stinckens et al., 2016; Vergauwen et al., 2015).
For juvenile and adult fish, measurements of swim performance vary. However, in some circumstances, a swim tunnel has been used to measure various data (Fu et al., 2013).
Domain of Applicability
Importance of swimming performance for natural behaviour is generally applicable to fish.
