On a first light, early morning walk along South Beach this time last year, I was surprised to find a huge fish lying on the sand at the high tide line from the night before. As graceful as it was there wasn’t a mark on it to suggest why it had died, not even a broken hook in its mouth. It measured exactly one metre in length, with huge scales, and it weighed around 20 kilograms. I sent photos and information on where it was found to Jeff Weir at the Dolphin Research Institute for proper identification. Jeff informed me that David Donnelly, their research officer who – according to Jeff – ‘knows his fish’, said it was a blue-eye trevalla.
