History of overfishing
At a long time in the 11th century the people started to stay without fish and in that time people eat fish and what they catch so when they started to stay
without fish they were hungry one day they started fishing in other part that usually they did not go and catch a lot of fish from that moment on the fish gust there but now this is a problem for the environment the fish population is ending and some people are very persuaded of that because scientist and investigators say that in 2048 the fish will collapse and with that can be a bigger problems to the environment like climate change and habit destruction now days the over fishing is coming a bigger problem because of the radars and a
lot of that type of thing with the radars is very easy to look for large fish banks and go fish them is not like in others times that more fish were saved because fishers did not know where to look and now is very bad because they do know were and who to look for them and they not always catch gust fish

Fishery depletion
Sebastian Barra 8E 24/10/2013
Fishery depletion affects all the people, at least more than 10,000 because our sea and our sea animals are dying because the garbage on the water.14 billion pounds of garbage are on the ocean killing and destroying our nature. This kill us because an example would be that we throw a glass of medicine or poison on the water and it is broken so a fish can eat that glass and when we fish the fish then we will eat it and then the fish will be infected and we would be to.

Fish are the last wild animal that we hunt in large numbers. And yet, we may be the last generation to do so. Entire species of fish would never be seen again because of this problem. Since 1989 when the annual global fish catch fish 86.1 million metric tons.
In this pict5ure you can see how many animals have been fished. So this has been a big problem on the world and this affects us because then we could die.

USE AND EFFECT OF TECHNOLOGY IN FISHERY DEPLETION
BY: Carlos Bucheli
Technology has many effects when fishing. “High-Tech fishing is emptying deep seas,” (Effects of technology in Fishery Depletion) scientists prevented fisherman, although, we continue fishing in extreme quantities with the help of technology. One example of the
use of technology when fishing, are the fisher boats, they have the technology that was developed for the cold war; like radars and scopes. Scopes lets fisherman detect where fish are. “As a result, many deep-water fish are being fished so heavily that soon they could reach extinction,” (Effects of technology in Fishery Depletion). Other equipment used is:
“sonar technology, satellite navigation systems and depth sensors,” (Effects of technology in Fishery Depletion). Another fact is that some big fishery companies use helicopters or spotter planes to locate tunas in the Pacific. Also technology is used in gear and tools for fishing. For example each time the suits are more resistant to cold waters, and tools like bigger, lighter and more resistant fishing nets. In consequence of this advanced technology, many fish are disappearing, although some fish can recover quickly from being fished. In these past two years, with the help of technology, we have fished about a 150% more than the past 5 years. If we continue using advanced technology, and fishing in this giant quantities, soon, fish will disappear from our planet.

Overfishing Bluefin Tuna in the Pacific Ocean
Bluefin tuna is a very unique fish that many people love. But they captured many of them in the Pacific Ocean. Fishers fished Bluefin tuna, but they gathered more than what they needed, and this mistake caused this animals to be in danger of extinction.
In the northern Pacific Ocean fishers captured 96% of Bluefin tuna fish that lived in it. But they fished more than what they needed. 90% (9 of 10) of the fish captured were newborn or hadn’t reproduced yet, so they were useless. This might cause the ocean to have its last generation of Bluefin tuna fish. “There is no logical way a fishery can have such a high level of fishing on juveniles and continue." said Amanda Nickson (Earth Island Journal). This fish is very important for many food chains, because it is the basis. The worst part is that for this fish it is very hard to reproduce, it takes them from 4 to 8 year.

Bluefin tuna is a very exotic fish and it is very expensive. One big Bluefin tuna was sold for one million dollars. Many people eat this fish on exotic foods like sushi rolls and special fish plates. 2/3 of this unique type of fish comes from the northern Pacific Ocean. It is very hard to stop this fishery because it is very expensive so people can become wealthy by fishing the Bluefin tuna and also a lot of people´s lives depend on fishing because it
is their way of obtaining money. The main fishers of this fish are Japan, Mexico, South Korea and the United States of America. Since the occurrence, people no longer can fish in the northern Pacific Ocean.
In conclusion people should stop fishing in big quantities because it harms humans, the environment and other animals. Overfishing is very bad! It causes many fish to go in extinction just like it happened to the Bluefin tuna! So, do you think it´s fair that because of people´s bad use of fishing many of them go in extinction?

All About Overfishing Overfishing occurs when fish and other marine species are catch faster than they can reproduce. Overfishing the talking of wildlife is too high for fished species. The earliest overfishing occurred in the early 1800s reduced the whale population. Some fish that we eat were also to the extinction in middle 1900s to the food chain. This will end when we faced with the collapse of large fish population. The industrial fishing had reduce the number of large ocean fish to just a 10% in the industrial population. A study of catch data published in 2006 in the journal science grimly predicated that if fishing rates continues in 2048 it collapse all the fish population. Many marine scientists believe that overfishing is the most threat in the ocean. The overfishing increases the total catch by 400% in 1997-1998. In this year they catch estimated of 93 million tons of fishes. Over three quarters of our planet are covered by the oceans. Their biodiversity is unmatched and they contain over 80 percent of all life on earth and we are catching more fishes that we can catch. The humans are catching more fishes than the ocean can produce if we still like this we do that the fishes extinct. So in my opinion people can catch the fishes but they need to give the fishes more time to reproduce so we can have more fishes to catch.
