A fellow on the beach today was fishing in a very interesting way. He had a couple of rods and reels on the beach. To carry the line out to sea though he used a drone. He said he was fishing for gurnard, trevally or tāmure, snapper.
The photo shows the vehicle with fishing rods, and also almost out of the photo at top left the drone carrying a line out.
The fisher also confirmed for me that the red-hued large dead fish I’d seen further down the beach was a snapper.
