What are the pros of Muro Ami?

Question

Muro Ami is the crushing of corals underwater to scare fish into nets

Answer 1

It makes the costs to catch fish lower which means we can buy fish for less cost.  I happen to thinkk this is not a good reason, but you did ask for reasons.

Answer 2

This centuries old means of harvesting fish is practiced my smaller fishing communities around the Pacific Rim.  It is an efficient means for these communities to create large catches.

That's about the only good I can say about the practice.

Not only does this destroy coral reefs, but entire ecosystems as well -- killing or displacing entire species of sea life.  It's a trade that should have been stopped decades ago.  In addition to the heavy environmental damage it causes, it involves significant use of child labor as well (see link below).
