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  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.
