What's the difference, if any,...
...between a whiting and a ground mullet? I was down this past week surf fishing, catching a grunch of both on Fishbites with very light tackle, and a gent I was fishing near told me they are related but different species of fish. He said the way to tell the difference is 1) ground mullet have a thread fin on top running off the dorsal fin and 2) whiting have a visible black spot on the top of the tail fin. I've looked on line but haven't found a definitive answer yet.
It's not that big a deal, I just wanted to know. I was fishing strictly catch and give away, primarily to him...he said they were both pretty good eatin' fish.
Any help would be appreciated...thanks in advance.
