Answer: False
Long line fishing involves the long line of wire attached with hundreds and thousands hooks to catch up the fishes.
Drift netting is a fishing technique where the nets are dropped vertically in the water and one end of the net is attached with a pole and other end is attached with the moving water vehicle. The fishes caught up in these net.
Trawling is another fishing technique in which the water vehicle discharge a cone shaped net in the bottom layers of sea water which collects an appreciable quantity of fish mass when the vehicle moves.
All these methods of commercial fishing are efficient to catch significant amount of by- catch. Hence, the statement "Long line fishing, drift nets, and trawling all produce an insignificant amount of by-catch" is false.
