Hook and line is one of the best methods of fishing with regards to sustainability. This can involve one person and a rod, or alternatively using a basic winch with a line of hooks. The hook and line fishing method has little impact on the surrounding environment and the catch can be selective. For example, any fish too small, or not the right species can be placed back into the water, with limited harm.
A fishing method that uses one or several nets with an otter board to keep the net open horizontally. The net will be towed from the stern of the boat and can be either demersal (on/near sea bed) or pelagic (mid-water). Bottom trawling is a type of trawling that sets the nets on the seaﬂoor. Heavy weights are attached to the nets to stir up the sand or mud so that fish and shrimp living there can be caught. Sometimes heavy rockhoppers are used, chains with roller wheels that allow the net to roll over rough, rocky seabeds without damaging the nets or being stopped by the rock.
