The Strait of Georgia surrounding the island is commonly fished for many species including all five spices of Oncorhynchus (Pacific salmon), Lingcod, Rock cod and coastal cutthroat trout. Inland lakes also are home to several species of trout, including a unique variant of stickleback native only to the island. The islands larger streams have small salmon runs. Various species of seal have breeding colonies on the shores of Texada Island and neighbouring rocks; sea otters are rare, but sometimes can be spotted. Orcas, which commonly feed on the seals, are the only large marine mammal that are seen extremely close to the island's shore. Other whale and dolphin species do migrate through the strait, but are rarely seen near land.
