🌀 Behaviour

Behavioural data for Barred surfperch is currently being reviewed.

🦐 Diet

The diet of the barred surfperch consists predominantly of sand crabs, which may be as much as 90% of the fish's diet. They also eat polychaete worms, skeleton shrimps and gammarid zooplankton, and small fish like anchovies and juvenile sardines. It also consumes small bivalve mollusks like bean clams and small mussels. Younger fish occasionally eat fish eggs of the Northern anchovy (Engraulis mordax), Pacific sardine (Sardinops sagax caeruleus), and smelts—Osmerids and Atherinopsids. As a demersal feeder, they are often found close to the bottom of the seabed.
