Abstract
Infrared (IR) light is widely accepted as a non-intrusive lighting for discreet observation but relevant studies are scarce. The response of European seabass Dicentrarchus labrax (Linnaeus 1758) towards IR light was tested during laboratory experiments alternating sequences of IR light and dark conditions. Swimming trajectories were extracted from hydroacoustic videos and behavioural metrics (e.g. speed, bearings) were quantified from the D. labrax movement patterns. D. labrax showed no preference nor deterrence towards IR light, supporting the use of discreet IR light as an alternative to visible light for monitoring unbiased D. labrax behaviour.
期刊介绍:
The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
