The annual spawning run of the official state fish, often called the âsand bass,â occurs during the spring and is perhaps best described as a âfish frenzy.â White bass move in large schools to spawn, and anglers who fish at the right time can end up with near constant angling action as well as a stringer full of fish.
The Atlantic salmon is an anadromous species, that is, it spawns in freshwater streams, the adults return to sea and the young remain in fresh water for 2 or 3 years. When the fish are about 15 cm in length, the young salmon (smolt) migrate to sea where they may live for 1, 2 , or more years before returning to fresh water to spawn. In Canada, Atlantic salmon spawn in October and November. The actual date depends on the region.
