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.
