cientifically it is a Stereolepis gigas
There have been two common names
F&G bulletin #68 , 1948 by Phil Rodel page 51
"Black Sea Bass"
F&G bulletin #157, by Miller & Lea page 149
"Giant Sea Bass"
Earlier in 1958 in F&G "Off shore fishes of California" by
John Fitch page 53
"Giant Sea Bass"
John Fitch was and still is considered the expert on the "Sea Bass" Therefore use "Giant Sea Bass"
However, there are those whom you will possibly encounter who's diving predates 1948 and they only knew them as
"Black Sea Bass"
So it all depends who you speak to and their age and experience
Now a new scientific name ... what they really see are
pretty large polka-dotted wreckfish
(
Stereolepis gigas)
It is recognized they do grow large; they do have spots but I have yet to experience them on a wreck.
Generally they annually migrate into the shallows duriing breeding the spring and summer into specific number of places in Catalina , one was and still is Goat Harbor. Currently The Dive Park has become a gathering place is a sure thing to see them apparently year round.
They were are still are occasional spotted in the many mainland coves from Crange county to the Mexican border during breeding.
On Memorial day 1960 the late great SoCal diver, underwater artist - see his painting "Night dive" cover on SDM- and member of a very active dive club, "The Snorkels" speared the world record fish, by breath hold diving, off then Scotsman's cove now called Reef Point , I would tell you the weight but my friend from the hinterland
@Jayfarmlaw has set the size of the fish at 500. no 600. no 1000 now 1500 pounds. So expert professional marine biologist
@drbill tell us about the fish ??
Sad note -- I recently was notified that Bob Stansbury who held the Black Sea Bass Spearfishing record passed away in Arizona .
The passing parade -- soon it will be I think, I suppose, I believe, or I was told..
