Boniare is a beautiful island.

I'm sure you meant trolling and not trawling, just a typo. As we all know, trawling involves a net and trolling is trailing a line or lines behind a boat.

Catch and release for bill fish is the right way to go.

With Go Pro cameras, cell phones et al you can bring the catch to the side of the boat and record the event for posterity. [...]
