Stickleback (Gasterosteus aculeatus)

In shallow water along the shores of the loch you may be able to spot some of the small fishes that live amongst stones or around weed beds. The Three-spined stickleback is a native species. It is found in both freshwater lochs, pools and rivers and in brackish waters. Adult sticklebacks are usually between 3 and 5 cm in length. They make nests from plant materials and males develop a bright red colouration during the breeding season.
