Detailed explanation-1: -Bottom trawling, a fishing method that drags a large net across the sea floor, is extremely destructive, destroying as it destroys entire seafloor habitats including rare deep sea coral and sponge ecosystems that take decades to millennia to develop.

Detailed explanation-2: -Bottom trawling, the practice of pulling a fishing net along the sea bottom behind trawlers, removes around 5 to 25% of an area’s seabed life on a single run. This method of fishing tends to cause a lot of bycatch. A study of La Fonera Canyon compared trawled versus non-trawled areas.

Detailed explanation-3: -Destructive fishing methods like dynamite, gill nets and beach seines are highly unsustainable because they typically do not target particular fish species and often result in juveniles being killed in the process.

Detailed explanation-4: -Bottom trawling is an industrial fishing method in which a large net with heavy weights is dragged across the seafloor, scooping up everything in its path. These nets are capable of destroying enormous swaths of fragile seafloor habitats, including fragile cold-water coral and sponge ecosystems.

Detailed explanation-5: -Blast Fishing The explosions often destroy underlying ecosystems from the strength of the blast. Around 70, 000 fishermen still use this practice. Researchers believe that destructive fishing practices like blast fishing are one of the biggest threats to coral reef ecosystems.
