Herring and Shad: Unique Features and Fishing Practices in Yaquina Bay

The Herring (Clupea pallasii) grows up to 15 inches and is prominent in Yaquina Bay's late February to early March fishery. Herring stay in the safety of deep waters during daylight, surfacing at night to feed on plankton while swimming with mouths open for filtration. The Shad (Alosa sapidissima), the largest member of the herring family, possesses the remarkable ability to detect ultrasound, aiding in evasion from dolphins that use echolocation to hunt prey. Together, these species highlight the intricate dynamics of marine life.
