Crangon franciscorum is a species of shrimp in the Crangonidae family which is endemic to California,[1] and found from Puget Sound in the north to San Diego, California in the south.[2] Its common names include bay shrimp, sand shrimp, common shrimp, grass shrimp, black shrimp, California shrimp and black tailed shrimp.[2]
This shrimp species is "an important part of the estuarine food web" in the greater San Francisco Bay.[3] It feeds on bivalves, amphipods and foraminiferins, and is prey for various fish,[3] including striped bass, white sturgeon, Pacific tomcod and shellfish such as Dungeness crab.[2] Its diet is "heavily influenced by predator size, temperature-salinity preferences, and prey availability."[3]
When exposed to sewage in a laboratory, the species shows behavior described as "avoidance of the toxicant".[4] It is "sensitive to pollution in estuaries".[2]
This species was by far the most common type of shrimp in San Francisco Bay in the 19th century, and was the most important species for its commercial shrimp fishery from the 1870s to the 1930s, accounting for about 90% of the shrimp catch.[5]
