The term gaspereau is the most common name used for two species of the herring family. Depending where you live they are also called river herring, alewives, grey backs, blue backs, kiacks and sawbellies. • Nova Scotia anglers are familiar with seeing gaspereau in lakes and rivers when they spawn in May and June. They are a diadromous species which spends most of its life cycle in the sea, returning to fresh water to spawn. • Spawning occurs over a six-week period as the water warms up. No nest is built. Gaspereau eggs are tiny, about one millimetre in diametre and, depending on water temperature, will hatch in about a week. The young fish spend the summer feeding in fresh water and, beginning in August, they begin their downstream migration to the sea. This fresh water growth is very rapid and some fish will be up 15 cm long at the end of the summer. Gaspereau first spawn after two years at sea and many survive spawning to return several times. Gaspereau up to 20 years old have been recorded from Nova Scotia. #lynnhemeon • If you enjoy my videos please subscribe: / lhemeon
