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).
Prionace glauca, blue shark,
This one washed ashore on December 8, 2019, on Samoa Beach, California. It looks to be bycatch.
Raja binoculata, big skate
The egg case is featured in Mermaids Purse.
Big skate egg case how I found it- a dog beat me to it! 
Flipped over for a more traditional view 
Big skates can produce egg cases longer than a pounder
Hydrolagus colliei, spotted ratfish
Clupea pallasi, Pacific herring
Age 1
Sardinops sagax, Pacific sardine
Alosa sapidissima, American shad
Oncorhynchus kisutch, silver or coho salmon,
Alepisaurus ferox, longnose lancetfish
This lancetfish is featured in Oceanic Predator Washes onto the Beach.
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

Ammodytes hexapterus, Pacific sand lance
The image below shows two sand lance in a sand-filled tidepool
The video below shows the same two sand lance swimming around, waiting for the turn of the tide.
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.
