Very cool!!
I have no clue what you all see down there, but if you go North into BigSur or further you will for sure see Blue and Black rockfish and now that Blacks have a sub-limit in the RCG bag of 10 it is important to know the difference...
Super easy to tell underwater...blues are mottled looking and blacks have an obvious streak on their side and spots along their back...they kinda look like a black/white version of an Olive to me...
I've attached a pic of the DFW wall chart, a pic my buddy Harold took of a big school of blues with an Olive in the middle, and a pic of Harold with some small blacks...also added one of a camoed male cab guarding some eggs.
Sincerely,
Jim
