Hungry tropical fish, sea urchins marching south as kelp forests disappear

From ABC Australia, again:
"However, kelp forests there — from Byron Bay all the way to Tasmania — are in decline as waters become warmer, seaweed-eating tropical fish move south and sea urchin numbers explode. "
You have the same problem in the US [from what I have read].
Tropical fish follow warmer waters south, devouring kelp forests

We do have an exceptional problem with purple sea urchins and loss of kelp in California especially north of San Francisco on the North Coast. However we do not have any tropical fish.

I’m waiting for the lobsters to show up.

Did an AAUS course about a week ago and found a barren developing at one of the survey locations in Big Sur. On some of the transects, you had to count over 200 purps before reaching 5m along the tape.
