Answer: Drift nets are used for the purpose of catching the fishes for commercial purposes.
Explanation:
The drift nets are also called as ghost nets because they are harmful for the large scale biodiversity of the ocean. They catch everything in their path plants, and unwanted marine animals. They catch non-commercial fish species, sea turtles, seabirds, sharks, dolphins, and others. This makes the bycatch net heavy and it becomes difficult to deal with such unwanted fish species for the fisherman too.
