Prezi data on the ecosystem

  1. Is commercial fishing threatening the ecosystem?

  2. What is by-catch?

  3. What is a ‘Dolphin safe label’?

  4. Are there any sustainable ways of fishing if so what are they?



  1. Yes commercial fishing is threatening the ecosystem in many ways such as…

  • Stopping fish from being able to reproduce

  • Less fish are in the ocean which can affect the food chain and many other things

  • Some fish start to over populate because we keep fishing certain fish that eat certain fish

Average amount of fishing has mostly been illegal internationally, including protected fish and masse’s of those protected fish end up on our plates. Former workers in the past have reported that entire teams were enslaved and forced to work without wages.these workers sometimes get Abusive beatings and are forced to work until exhaustion are commonplace on certain ships. Certain workers in these situations are getting less sleep than needed and a lot of them are still children. Addition to all these things (illegal fishing) causes extreme damage to the ocean because environmental regulations are typically not followed.



  1. Bycatch is where the unwanted sea animals have been caught and just left to die such as…

  • Dolphins tuna fishing is estimated to have killed nearly 600,000 dolphins.

  • Sea turtles

  • Protected fish 

  • Sharks

  • Whales

  • Sea birds

  • Cetaceans

  • Seals

  • Sealions

Around 720,000 sea birds, 300,000, 345,000 seals and sealions and over 250,000 sea turtles die because of being caught in fishing gear like nets, hooks, fishing line and many other fisheries around the world annually.




  1. The dolphin safe label was made to “protect the dolphins” even though it was a big fail. It was in compliance with the U.S laws and regulations of tuna fishing operations.


  1. Yes there are ways of sustainable fishing for example in the Philippines of the Tagbauna people they sometimes use spears to fish (example down below)

 

Some people use a spear gun which in my opinion is less work in order to shoot at the fish that you are planning on catching.

Some other places go fishing for a certain fish each season of the year which means fish don’t overpopulate, go endangered or go extinct.
