Sticklebacks
Change in Males during Spawning Time
More than fifty fish species live in our lakes and rivers. The sticklebacks count among the smallest native freshwater fish.
The three-spined stickleback is of an inconspicuous colour almost all year long.
But during the spawning season, something extraordinary happens: the body colour and behaviour of the males change. Therefore, this small and ordinary fish attracted the attention of behavioural scientists early on.
