Ghost Nets - Other Issues Presentation

Dude, let me introduce myself before I begin my gnarly rant.  My name is Crush.  I am best known for my role in Finding Nemo but I am also an advisor for the United Nations Environment Program.  I have been called here to better educate you on the problem enveloping my home—the problem of Ghost Nets What are those you ask, well I would love to inform you.  Ghost Nets are abandoned, lost, or discarded fishing gear.  So there are lost nets and traps, but the ocean is pretty big and the few lost items cannot make that big of a problem, right? No, dude that is wrong.  An increased scale of global fishing has resulted in 6400 tons of marine litter from Ghost Nets alone.  That’s 10% of all marine litter! You are listening now, aren’t you?  Let’s dive into the problem so more.  There are two main culprits to the existence of Ghost Nets:
      Bottom set gill nets are anchored to the sea floor and held up by floatation devices on the ocean top.  Spanning a large range of the sea (600-1,000 meters) allows for an abundant amount of fish caught when used correctly, but also means when they break loose the nets trap many marine species. 


            Traps and Pots are used predominately for catching lobster and crab. These traps are set submerged in the water and await the arrival of the crustaceans.  The crabs and lobsters enter the trap, and then as the name says, become locked in the contraption.  Super effective in making sure my marine friends do not escape but just as effective in capturing them when the traps become lost and are no longer handled by humans.  Some of my fellow marine friends call them the Trap of Death, but don’t let that control your opinion.  I am just here to offer an educated and non-biased opinion since I do live among these environmental invasions.



I have tried to understand how so many have become lost at sea, and I get it.  The human population has increased, man, so fishing has to increase.  It is easier to buy new nets for the fishermen than put in the energy and money to find lost equipment.  Technology has allowed for easier and more efficient fishing. Good for the wallet, bad for the environment. Instead of buying a new net, can you fishermen just get better track of your nets and repair them? (Conspicuous Waste).

Alright human specimens, I want you to better understand what it is like for marine species like me. Watch this video

Ghost Nets are deadly because of their small holes and the easiness it takes for them to become tangled up with themselves. These nets restrict movement, causing starvation, laceration, infection, and suffocation in those that need to breathe at the surface. Dude, I have had many friends die from nasty infections and even some of my turtle friends have had to have their limbs cut off! Not only do these nets get caught on our bodies, but they even get caught on places we marine life call our home. If caught on wrecks, nets can suffocate a wreck and thereby render hiding place for marine life useless, or even trap them inside. If my home is trapped, where am I supposed to live?

Not only does it harm our bodies and living quarters, but it also harms the whole sea floor environment. When caught on a reef, Ghost Nets do not only catch fish, turtles, crustaceans, birds, or marine mammals, they also destroy hard and soft corals, wiping out complete ecosystems while swaying in the current. Now that’s not cool, you hurt my friends and ruin the entire ecosystem!!!

Now you are probably wondering... What can we do about this problem that is hurting many different types of animals and ecosystems? There are many different solutions in the works, but even a few that are already in effect. Some countries use escape hatches on traps in order in release marine life after the trap has been submerged for a long period of time. There are also nets made out of cords which break apart from the net when large marine life swim through, but stay intact for the fish meant to be caught. I am also sure a lot of you have heard that us big animals are scared of loud sounds, this is a good thing because there are now sound-reflecting material to drive large animals away. Since humans are a part of nature and dependent on the environment they need to take care of marine life and waste created!! (Moral Holism).

There are a lot of things already in the works to prevent these Ghost Nets from happening, but you should take a little time to think of your own solution! Here are a few ideas to get the ball rolling:

1.     Financial Incentives à Encourage fishers to report lost or stolen gear and bring old and damaged gear to the port. Give them a couple of bucks for their damaged/found gear may work!
2.     Mark Personal Gear à Marking your own gear will allow the identification of the gear. Since some hear is left in order to catch fish over time, some nets are supposed to be left alone. Making a universal system will help all fishermen.
3.     Improving disposal and recycling methods à Have ports provide safe disposal of material since no one wants to take care of their own garbage

Now that you know all about Ghost Nets, get out there and do something about it! These problems in our environment will not end until someone puts their foot (or fin) down and says enough is enough!!!
