Unit 2: Mighty Herring

In this unit:

Pacific herring are small schooling fish that play a big role in marine food webs by supporting salmon, which in turn feed the Southern Resident orcas. These little but mighty fish have a long history of significance- culturally, economically, and intrinsically.

As a food source, herring provide energy to lower trophic levels of the Salish Sea (egg predators) as well as to upper trophic levels (predators that eat larvae, juveniles, and adults). They are also a culturally important species for tribes and First Nations in the region, and are economically valuable to commercial fisheries in the Salish Sea (The SeaDoc Society). The shorelines of the Salish Sea come to life when schools of herring are present. It is quite the site to see, especially underwater, but even from the surface you can witness diving marine birds, hunting harbor seals and sea lions- and the reefs below start teaming with life during these feeding frenzies.

Might Herring Part I
Mighty Herring Part II

It wasn’t until 1979 that San Juan County got a comprehensive growth plan and that was largely due to the Friends of the San Juan’s being there to advocate for the shoreline and the ecosystem. Since then, there have been constant waves of pressure by developers. Friends have risen each time, fighting to protect this fragile and precious place.
