Here I feature some fishes, other than surfperches, that I’ve caught in the surf zone, or found washed up on northern Oregon beaches. The common names and organization are more or less those of Love (1996) and Miller and Lea (1972).
Blue Shark, Prionace glauca– This one washed ashore on December 8, 2019, on Samoa Beach, California. Looks to be bycatch.
***
Big Skate, Raja binoculata– This is the egg case. It was featured in Mermaids Purse.
***
Spotted ratfish, Hydrolagus colliei
***
Pacific herring, Clupea pallasi
***
Pacific sardine, Sardinops sagax
***
American shad, Alosa sapidissima
***
Silver or coho salmon, Oncorhynchus kisutch
***
Longnose lancetfish, Alepisaurus ferox– This lancetfish appeares in Oceanic Predator Washes onto the Beach, and these lancetfish photos are courtesy Mary and Sam Phillips.
***
Three-spined stickleback, Gasterosteus, aculeatus– The sticklebacks I come across are ones cast up onto the beach. They live in almost every coastal stream. Why do they end up in the surf? Threespine sticklebacks appear in Stranded Sticklebacks.
***
Greenling (juvenile), Hexagrammos – The tow images below are the same fish, first when I encountered it cast up on the beach, then cleaned up and released into a sand-filled tide-pool. This juvenile Hexagrammos appears in Stranded Greenling raises eternal question: To Assist or Not Assist?

Pacific staghorn sculpin, Leptocottus armatus
Leptocottus armatus is a camouflage artist | Look for a black spot on the first dorsal fin 
Quite a nice pattern on those pectoral fins 
Staghorns get their common name from antler-like extensions on the preoperculum 
Leptocottus armatus are most abundant in the surf zone during summer
***
Sand sole, Psettichthys melanostictus
***
Unidentified juvenile pleuronectid- I found this nearly transparent beach cast juvenile on the central Oregon coast, July 2018.
***
Another unidentified pleuronectid- The suggestions I’ve gotten so far are starry flounder and maybe curlfin turbot. Do I hear any other suggestions? Just a few centimeters long, this is a beachcast fish.
A beachcast juvenile pleuronectid | July 7, 2020 
Same fish suffering the indignity of my finger bowl before its release

Common mola, ocean sunfish, Mola mola

You have misidentified a Shad as a Sardine.
