I Need Your Help!

Here is a photo of my grandfather Ralph Sever circa 1937.

The S between Scott and Heywood stands for Sever.

Grandfather Sever was a die-hard fisherman… I thank him for that! He taught me a lot about fishing! Please notice he is wearing a tie. When we went fishing in northern Michigan, this is how my grandfather dressed... think about that next time you don your fishing apparel!

I want to figure out where my grandfather was and what species of fish this is. I think this might be a yellowtail, but I can't quite tell. Does anyone know where this is or what fish this might be. His daughter, Carol Baumhardt, thinks this might be in California and he was fishing with a cousin who lived in Whittier, CA.
PLEASE, can anyone help identify the location or the fish?!
