Pacific Herring

(Clupea pallasii)

    Both adults and juveniles have been observed in Fishing Bay. A
     large spawn was noted in April of 2012.
     Look for:  Slim body 
                        Silver-white side and belly with blueish green 
                            dorsal area
                        May reach up to 45 cm, more typically around 33 cm
                        Single dorsal fin located mid-body
                        Fins are u
n-spined
                        Deeply forked tail
                        No scales on head or gills
                        No teeth on jaw line
                        Large eyes
     Diet:  Plankton including copepods, amphipods, fish larvae
                    and molluscs.
    Habitat: Spawn in inshore waters and feed in offshore waters
                    to depths of 1300 ft.
    Range: Baja California to Siberian Arctic
    Reproduction: Prefer to spawn in sheltered bays and estuaries.
       Adults make their way from the open ocean to these protected
       areas where the female lays up to 20,000 eggs in the shallow 
       inter-tidal among submerged vegetation or eelgrass.  The
       spherical eggs, measuring 1.2 to 1.5 mm in diameter incubate
       for about 10 days.  Juvenile 
survival rates are low, only about 
       one adult per 10,000 eggs survives to adulthood 
due to high 
       predation rates.
