Striped bass
In Canada there are no landlocked striped bass, but a large number of bass overwinter in Grand Lake, Nova Scotia. They migrate out in early April into the Shubenacadie River to spawn. These bass also spawn in the Stewiacke River (a tributary of the Shubenacadie). The Shubenacadie River system is one of five known spawning areas in Canada for striped bass, with the others being the St. Lawerence River, Miramichi River, Saint John River, Annapolis River and Shubenacadie/Stewiacke Rivers.
