It was fascinating watching swirling masses of Northern Anchovey from a bridge over the Slough. Large schools were swimming in tandem, opening and closing their gill rakers.

"The Elegant Tern’s fates are closely tied to those of its main source of food—the northern anchovy. When anchovies are abundant, the terns have high breeding success, and vice versa when anchovies are scarce. The distribution and abundance of these small fish, in turn, is heavily influenced by oceanographic conditions such as El Niño." https://www.allaboutbirds.org/guide/Elegant_Tern/

Northern Anchovy (Engraulis mordax), a.k.a. California Anchovy, is a marine, ray-finned fish in the Anchovies (Engraulidae) family. It is found in the Pacific Ocean, ranging from Mexico to British Columbia. They have streamlined, spindle-shaped bodies. Anchovies "school" (swim close together in groups). They eat plankton which they filter from the water with their GILL RAKERS.

Northern Anchovey:
"Commercial fishing: As sardine populations declined in the Pacific during the 1940s and 50's, fish packers in America started canning the more abundant local anchovies. Total hauls increased over this time from 960 tons in 1946 to 9,464 tons in 1947 and peaking at almost 43,000 tons in 1953. From 1949 to 1955, they were restricted for all uses but bait fish in California. In 2010, reported American hauls totaled 2,100 metric tons. Most Californian anchovies today are fished for use in animal feed and as bait fish. Recreational fishing: They are taken by anglers for use as bait or for personal consumption." https://www.inaturalist.org/taxa/63770-Engraulis-mordax
