Fishing for Blue mussel

The blue mussel is a bivalve with a smooth, wedge-shaped shell, blue-black to brown-purple outside and pearly within, anchored to hard surfaces by tough byssal threads. It forms dense beds on rocky intertidal and subtidal shores of the North Atlantic and tolerates a wide range of salinity. The shell reaches about 6 inches. Once settled, it stays fixed in place.
