Grow out of Leopard Coral Trout in net pens can maintain supply at peak times of demand (i.e. Christmas and Chinese New Year), and ensure stable supply throughout the year.
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.
A banned fishing method, though nevertheless still used due to lack of enforcement. This involves spraying a sodium cyanide mixture into the water to stun the fish, and used in the collection of fish for the aquarium and live reef fish trade. This practice not only results in higher mortality of the target species, it also damages other marine organisms, including corals. It is not known if there is any human health impact from eating fish that has been caught with cyanide and this is something that needs to be examined.
