Overfishing and destructive fishing practices that are negatively impacting the oceans
ByOverfishing is when people catch fish more then the system can support, leading in a decline in the fish population. Overfishing has caused ecosystems to change. People are taking fish out of the oceans at a faster rate then they can reproduce. This causes a change in the food web, and declines the stability of ecosystems. Decades of destructive fishing has resulted in the decline of fish stocks such as bluefin tuna and Grand Banks cod.
Systematic overfishing is only made worse by illegal catches and trades. Some of the worst ocean impacts are caused by illegal fishing. When you take more fish out of the ocean than the fish can reproduce, it leads to a major crisis. Bycatch is when fisheries capture unintended fish species. This wildlife is treated as waste, and is thrown overboard either dying or dead. Harmful fishing gear also is destructive. Harmful fishing gears include bottom trawls, gillnets and dredges. These can affect the sea habitats and increase bycatch.
In 1993 the Atlantic northwest cod fishery collapsed as a result of overfishing, and to this day it still hasn’t recovered. By the 1960s, the fisheries had powerful equipment which helped them catch more fish. The cod stocks peaked by 1970s and 80s, but the stocks were depleted faster then they could reproduce. The cod haven’t recovered from this yet, they are expected to by 2030.
