Long line fishing, drift nets, and trawling all produce an insignificant amount of by-catch.
kolezko [41]

Long line fishing, drift nets, and trawling all produce an insignificant amount of by-catch is a false statement.

Explanation:

Bycatch fishing is "the incidental capture of non-target species” like sharks, dolphins, seabirds, marine turtles and other marine organisms while applying modern fishing gears like long line fishing, drift nets, or trawling.

Although, these inconspicuous modern fishing gears are highly efficient in catching the desired types of target fishes; these also catch significant amount of other marine species which travel along the line as a bycatch.

A huge number of exclusive marine fishes which are mostly under the endangered list and many juvenile fishes are caught as bycatch which are mostly thrown back dead overboard. Further these modern gears also endanger the marine structures like the coral reefs.
