Alewife

The Alewife, Alosa pseudoharengus, is a small, schooling fish found in coastal waters and freshwater systems in North America. Recognizable by its silver body and dark spot near the gills, it plays a crucial role in the food web, serving as prey for larger fish. Alewives are known for their migratory behavior, moving from the sea to freshwater to spawn.

Living Conditions
🐟 Habitat preferences
- Alewives are typically found in marine, freshwater, and brackish environments, often inhabiting coastal areas and estuaries
- They prefer temperate waters and are frequently seen in large schools near the surface
- Alewives feed on zooplankton, small fish, and crustaceans, making them a key part of the aquatic food chain
- They are commonly found in environments with varying bottom types, including sandy and rocky substrates
♻️ Life cycle and mating behavior
- Alewives are anadromous, migrating from the ocean to freshwater rivers and lakes to spawn during spring
- Spawning occurs in shallow, quiet waters where eggs are released and fertilized externally
- After spawning, adults return to the sea, while larvae stay near spawning grounds until they grow
- Juveniles form schools and migrate downstream in late summer and autumn, eventually reaching the sea to continue their life cycle
