100' long x 6' tall fence nets weighted on the bottom with floats on the top set up in the shape of the letter J with a rubber band in the J pocket to make a tube. Once net was set, you would swim as far down the reef as made sense to start corralling the fish with 2 - 6' yellow fiberglass pokers to steer the fish towards the J shaped fish net into the pocket. Once in the pocket then hand net them out of the tube pocket into laundry baskets zip tied together one on top another with a spring trap acrylic top flap door. The basket would have a 6' clothes line weighted down with a 2 lb. lead weight. Each dive would net about 100 yellow tangs, 20 Naso's, 30 koles, and then an assortment of random fish. We would do 5 dives per day. most days would yield 600 fish and everything was well documented with the DNLR of Hawaii. The fishery was very well managed, one of the best it the world. You could go back to that same dive spot 1 week later and repeat the same process and fish amount. it is impossible to delete the oceans fish with a hand net and a dive team of two.
Silly politicians are clueless.
