Aquaculture experts from the University of Stirling and the Institute for Food and Agricultural Research and Technology (IRTA) in Catalonia, have found the way fish, Senegalese sole, cope with stress is determined by their personality and remains consistent regardless of the situation they are in.
Experts hope the first study to test stress copying styles in mature Senegalese sole, will help farmers screen fish from a young age to help the species reproduce in captivity and improve aquaculture production.
Scientists found when faced with confinement, restraint or a new environment, younger fish known as juveniles and older fish known as breeders, had similar behavioural patterns and levels of activity, showing consistent responses in animals of different ages.
There was also a correlation between how individuals with the same sort of personality acted across the various tests, suggesting that those who are reactive and fearful or proactive and curious, maintain this behaviour.
