Fish could have emotions and conciousness, according to new research published in Proceedings of the Royal Society of London, Biological Sciences, which has for the first time observed in fish a phenomenon known as emotional fever – the increase in body temperature when subject to stress – which has been controversially linked to consciousness.
Researchers from the Universitat Autònoma de Barcelona, together with scientists from the universities of Stirling and Bristol (United Kingdom), observed an increase in body temperature of between two and four degrees in zebrafish, when these are subjected to stressful situations.
Until now emotional fever had been observed in mammals, birds and certain reptiles, but never in fish.
For this reason fish have been regarded as animals without emotions or consciousness, but the experiment, with 72 zebrafish, has brought this view into question.
The researchers divided the fish into two groups of 36 and they were placed in a large tank with different interconnected compartments with temperatures ranging from 18ºC to 35ºC.
