The Roller-Net: A New Marine Sampling Gear

The roller-net, a new fisheries sampling gear incorporating features common to the pushnet and bag seine, is described. The roller-net is compared with nearshore gear types, including pushnet, bag seine, and minnow seine, in beachfront, grassbed, barren sand-shell, and soft organic substrates. The roller-net is effective in sampling nekton from grassbed and barren sand-shell substrates, but ineffective in characterizing beachfront and soft organic substrates.
