The Effect of Overfishing

Overfishing occurs when fish and other marine species are caught at a faster rate than they can reproduce. Around the world there are about 90% of large predatory fish stocks have gone. Forever! This includes the delicious and maybe expensive dinner favorites such as tuna and cod.

Watch this 2009 film...

Overfishing has led to the near extinction of not only many species of fish, but also other marine organisms, including coral reefs. When the fish that eat algae is removed from the coral reefs, algae grow. Algae will cover the coral reefs, thus killing the reefs.

It can also cause fish starvation. Starved cod fish have been found due to their natural food shortages. Click here for more information. And tons of them was found dead floating on the sea.

It is not only fish affected by fishing. As we fish we catch things that do not have commercial value as a marine mammals, sharks, sea birds, and non-commercial fish species. Over exploited, killed as by catch and discarded (up to 80% of catch for certain fisheries), and are threatened by industrial fisheries.

Scientists agree
that at current exploitation rates of many important fish stocks will be removed from the system in 25 years.


The big fish, bill fish, grouper, big things will be lost. It is happening now. If this happen unchecked, we will have a sea full of horrible little things that couldnot be eaten. We may end up with a marine junkyard dominated by plankton.
