Where can I find answers What is overfishing Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans.
Some of our consumption is to satisfy a desire for a particular food, even though the repercussions of these actions are often shocking. Many people who decide to begin eating more responsibly, continue to eat fish or other sea animals.
Unfortunately, fisheries and aquaculture Over fishing wreaking havoc on the oceans. Fishing vessels wage war on the oceans Modern fishing ships use technologically advanced fish-finding sonar that can find a school of fish with almost military precision. Once the fish are caught, the ship is used as a floating factory, with onboard processing and packing plants, preservation systems, and huge engines that allow the ship to drag their enormous nets through the ocean.
These are animals like sharks, bluefin tuna, swordfish, marlin, and king mackerel. According to Greenpeace, the depletion of these top predator species can cause a shift in entire oceans ecosystems where commercially valuable fish are replaced by smaller, plankton-feeding fish.
This century may even see bumper crops of jellyfish replacing the fish consumed by humans. Fishing disrupts the marine food chain After depleting the most valuable fish, the apex predators and large fish like bluefin tuna, the next step is moving down the food chain.
This means going after typically smaller species and fishing in different locations of the ocean. Overfishing has been happening for years and years Overfishing has been documented since the early s when humans took out select whale populations in search of blubber for lamp oil.
By the mids, Atlantic cod, herring, and California sardines were harvested to the brink of extinction. This depletion reached catastrophic levels by the late 20th century. Fact from National Geographic.
Fishing nets catch far more than intended The term for non-targeted animals that end up in fishing nets is bycatch. Many animals like turtles, dolphins, sharks, and sea birds, get caught on fishing lines or pulled up by nets then tossed back into the sea, often dead or dying. However, dolphin safe does not imply sustainable or responsible and the issue of bycatch is ongoing.
Bottom trawling is tearing the ocean apart Bottom trawling is the ocean equivalent of clear-cutting a forest. Ships drag huge, heavy nets held open by doors, many of which weigh several tons each, over the seafloor to catch fish that dwell near the bottom of the ocean.
In the process, they destroy everything else, including deep sea coral and sponges, and other sensitive seafloor life. Overfishing leads to unsustainable aquaculture Aquaculture, or fish farming, requires feed for captive fish.
To grow just one pound of farmed salmon, an estimated four to eleven pounds of prey fish are consumed.Learn about overfishing, one of the biggest threats to ocean ecosystems, and its impacts on fish populations and ocean health.

Overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish in time, resulting in those species either becoming depleted or very underpopulated in that given area.
