Thanks, Nathan, for you continuing excellent reporting on the condition and fate of our coral reefs.  Regarding the solution, if we find out that Uhu eat mudweed, then there should be a 5 year moratorium on spearfishing Uhu. What makes that a difficult decision is that a small number of loud supporters of spearfishing care more about their "catch" instead of the overall health of the reef.  Everyone should snorkel at Hanauma Bay to see how large the Uhu grow (in size and population) to understand the devastation that spearfishing has on the population on unprotected reefs.  However, protecting the Uhu is only one part of the solution.
