Freaked out fish - Snapper Alarm Pheromones
Freaked out fish – We know that most fish release ‘alarm pheromones’ into the water when they’re stressed i.e. being attacked by a predator. This signals to their other scaly friends there’s trouble and swim away as fast as your fins will allow. But when it comes to Snapper being stressed out, it seems they’re a whole other kettle of fish. Scientist Olivia Rowley explored why snapper are different when it comes to be scared, whether it could be classified behaviourally and physiologically and how the results can have implications for the aquaculture of this popular table species.
