What do you think is the most destructive fishing gear and why?


Trawls are one of the most destructive forms of fishing gear in the world. Shrimp trawls are notorious for the amount of bycatch, or untargeted catch, they haul in. Thousands of sea turtles, marine mammals and untargeted fish are caught in shrimp trawlers around the world every year.

What is the most destructive type of fishing?

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.

What is the most environmentally destructive fishing method?

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.

What is meant by destructive fishing?

1. A practice that uses fishing gear and technique, such as bottom-trawling, cyanide fishing, and fish bombing, that destroy fisheries habitat and inflict damage to marine environment.

Why is trawling so destructive?

Trawling destroys the natural seafloor habitat by essentially rototilling the seabed. All of the bottom-dwelling plants and animals are affected, if not outright destroyed by tearing up root systems or animal burrows.

Overfishing (i.e., catching more fish than the system can support) leads to declines in fish populations, ecosystem-wide impacts, and impacts on dependent human communities. Destructive fishing methods include the use of explosives to kill or stun fish, which destroys corals.

Why do people use destructive fishing?

These methods are used because they are effective in getting a large amount of fish in a short period of time saving fishermen time and effort. Some dangerous methods include over-fishing, blast fishing, bottom trawling, and cyanide fishing.

How destructive is the fishing industry?

Is bottom trawling destructive?

Bottom trawling is one of the most destructive methods to catch fish. Its extensive use for commercial fishing causes a high impact on marine ecosystems, often resulting in irreversible damage to sensitive habitats (such as maƫrl beds, coralligenous reefs, deep-sea coral reefs, gorgonian gardens and sponge grounds).

Why is bottom trawling a bad fishing technique?

The problem with bottom trawling as a fishing method is that it’s indiscriminate in what it catches. When dragging the large, weighted nets across the seafloor, everything that happens to be in the way gets swept up in the net too.

Why is trawl fishing bad?

Extensive new regions of the continental shelf, slope, submarine canyons, and seamounts have been exposed to the effects of bottom trawling and dredging. Expansion of fishing into new territory could lead to the loss of habitats that might have provided as refuge for heavily exploited species.

What is the most destructive wave type?

Of the two types of surface waves, the L-waves are the most destructive. They can literally move the ground beneath a building faster than the building itself can respond, effectively shearing the base off of the rest of the building.

What is the biggest danger in over fishing?

DEGRADED ECOSYSTEMS When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.

Why is longline fishing destructive?

An unfortunate consequence of the longline design is that it attracts and easily snags non-target marine life (known as bycatch). A wide range of animals such as sea turtles, sharks, seals, seabirds, and marine mammals can get caught on hooks or entangled in fishing line (Fig. 1).
