Storyboard Text

  • Hi there, my name is Finn. Take a swim with me and I'll tell you about the dangers of overfishing. Now-a-days overfishing is a hot topic, a big issue, something that is bad for the Earth. According to the article "Threat 1: Overfishing", "Overfishing occurs when fish and other marine species are caught faster than they can reproduce." This leads to fish depletion. Fish depletion is where we have a shortage of fish.
  • Harmful fishing methods are the cause of overfishing. According to the article "Destructure Fishing", "Bottom trawling is an industrial fishing method where a large net with heavy weights is dragged across the seafloor, scooping up everything in its path- from the targeted fish to the incidentally caught centuries-old coral."
  • Bottom trawling is just the main harmful fishing method. I learned from the "Sustainable Fishing Methods" other harmful fishing methods are dredging, gill netting, long-lining, and purse seining.
  • There have been many case studies of fish species and how they've been depleted. One of them is about bluefin tuna. According to the article "Case Study: Atlantic Bluefin Tuna", "Bluefin tuna are unique, perfectly adapted products of evolution. They are also dangerously close to becoming extinct." They are mainly marketed for sushi, which has made the stocks nearly collapsed. Attempts to fix this have failed.
  • A solution to all this? Sustainable fishing. According to the article "Choosing Sustainable", "'Sustainability' is based on a simple principle-meeting todays needs without compromising the ability of future generations to meet their needs." Sustainable fishing methods are hook and lining, harpooning, traps, and trolling.
  • There are ways to know that you are buying sustainably caught fish. According to the article "Choosing Sustainable", "Over the years many organizations have developed seafood seafood guides, eco-labels, and certification programs to guide seafood purchasing." You can use a seafood guide, which rates the fish species, fishery, or aquaculture practice. You can look for eco-labels, which are "seals of approval" given to aquaculture operations and fisheries that are deemed sustainable by third-party certification bodies. Or you could use FishWatch, which doesn't rate or rank one fishery or species over the other because they are legally harvested under the management of the United States. It looks like the end of the river. Keep these facts in mind and enjoy a good rest of your day. good bye.
