Identifying fishing grounds and Mapping ocean currents

PurseSeineSignature tn.jpg
- The image is of a typical purse seine signature, this is also how we can tell where the fishermen are dropping their nets. The boat goes very quickly in a circle, and the captain then puts the engine in neutral. They then close the top of the net, winch close the bottom of the net and drift for the next hour while the crew pull the net on-board by hand.
