Alosa sapidissima Spawning conditions Spawning migration distance During spawning season, they move to shallower inshore waters to spawn No data
Alosa sapidissima Spawning conditions Spawning season Spring ['April', 'May', 'June']
Alosa sapidissima Spawning conditions Spawning temperature Beginning when water temperatures reach 13 to 15°C, and ending when they exceed 27°C 13.0 °C
Alosa sapidissima Spawning conditions Spawning water type in their native coastal habitats, alewifes spawn in the upper reaches of coastal rivers, in slow-flowing sections of slightly brackish or freshwater. Flowing or turbulent water
Alosa sapidissima Spawning conditions Spawning depth Shallow, water less than 2 m 2.0 m
Alosa sapidissima Spawning conditions Parity Although alewifes generally do not die after spawning, the fluctuating temperatures that the adults are exposed to when they move to inshore waters often results in mortality due to osmotic stress. In some years, temperature changes caused by upwelling may result in a massive die-off of spawning alewifes Semelparous
