It's very funny. I had to search this article up since there was no link available. Anyways, I agree with the public outrage ranting about this. This is one example of why we as humans do stupid things that disgraces our nature. In this article, it says that his reason was creating attention to Fibropapillomatosis, a herpes-type virus that affects sea turtles worldwide. I wonder what his motive was to "ride" the turtle? Being so close to sea turtles might disturb their natural behavior patterns. http://digitaljournal.com/article/313913 First of all, I like your choice of picture! It’s very funny.

From your article, viruses seem harder to get rid of than it seems. I searched up what animals can kill viruses and I find out that some scientists use horses and cattles' immune system to hunt and purge cancer cells through the lymphatic system. I don't think it should be tested right away on humans so soon until they find a way to make it safer to use since it says it's very toxic. http://ecancer.org/news/75 That’s very interesting.

The gears of the nets which are attached to the ends include chains (to scare fish into the net) or airplane tires, metal discs or bobbins (which keep the net from getting caught on rocks). The habitats for the fish and other sea critters have been destroyed because bottom trawling has crushed and overturned corals and sponges, that attached to the seafloor, in which these critters live in. Bottom Trawling has helped decrease the population of the Bristol Bay red king crab in the early 1980s. This article is very important indeed because it has a big impact to the food chain and the economy. Bottom Trawling is causing the population of many sea creatures to decrease and maybe even go extinct. Prohibiting bottom trawling creates opportunity costs. It can greatly affect business worldwide, but it will surely save tons of marine wild life species. It can help bring the marine ecosystem back healthy and normal but it will take years and decades.

Bottom trawling crushes marine animals and reduces shelter for fishes or any other species. One million pounds of corals and sponges are removed every year in Alaska and these were just bycatch discarded by bottom trawlers. I didn't know that bottom trawling contributed to the collapse of the red king crab population in Bristol Bay. The population has been low ever since in that area. This article is important because it makes the reader aware of what harm bottom trawling can do to marine habitats as well as marine animals attached to the ocean floor. This article might also change trawlers opinions about what they are doing to the fish and their environment.They might also not waste so much fish if they know how much they are throwing away. This article could lower the destruction of habitats done by trawlers. The article was about bottom trawling and its danger towards marine animals and habitat on the ocean floor.

It said that bottom trawlers catch millions of pounds of unintended species. They only keep about 18% of what they catch, and the other 82% are discarded. The article said that their research shows that bottom trawling damages marine habitats by removing, crushing or overturning corals, sponges and other species that form the living seafloor. Bottom trawling contributed to the collapse of the Bristol Bay red King crab population in the late 1980s. It talked about in addition to altering habitats and ecosystems, trawling resulted in huge amounts of bycatch, which meant that they discarded a lot of the fish just because of the wrong species, size or sex. This affects entire marine communities. I think that this article was pretty important because it explains the impacts that trawling has and how trawl fleets are considered as " super- predators" to benthic communities.

Many marine lives relies on each other and without them the food cycle wouldn’t be complete and their population would decrease big time, just like in the article that I’ve read, it made king crabs’ population at low level. Trawling is not illegal it just destroys habitats for marine lives and they should make a certain depth for the trawlers so they could avoid destroying habitats. The article mentioned that over 1 million pounds of corals and sponges are removed from the seafloor every year. Unwanted fish and marine lives are discarded because they are the wrong size, sex or species and the bycatch can affect the entire communities and the food web. I think that this article is very important for us because if the corals and sponges keeps on getting destroyed by them trawlers, it might take years for some of them to recover and some might soon get extinct. Also rare species could basically get extinct forever. The article also mentioned that it reduces habitat complexity and associated shelter for fish and other species. Fishing is not bad and unrestricted, but when destroying habitats and over fishing I think that’s when they should restrict everything. What’s left for the future if this whole thing keeps on going?

Although this industry makes quite a bit of money, the fisherman might want to maybe change their nets or something to make it less destructive. I had no clue that this caused the Red King Crab collapse in Bristol Bay in the 80's. I do think that this article is important. I think this because, I fish also and I can understand what would happen if this caused many fisheries to collapse. Many people would lose their way of income, and the whole world would be suffering from not having the fish. I think that there should be some stronger laws on this type of fishery. Maybe change up the gear/how they use it. I think that this article was about how bottom trawling can effect many marine species, and their habitat.

For example, it destroys natural habitats such as coral and sponge beds, which other marine organisms depend on. It also decreases the population of marine animals such as the red king crab. They discard most of the fish, estimating around 82% of it, because they are not the right size, gender, or species. Luckily, there are some Alaskan fishery managers who tries to protect reduced populations and habitats by closing off certain areas of Alaska. This is a very important thing to consider. Bottom trawling should be banned because of its hurtful effects it is doing to the habitats and living critters that rely on them. Getting rid of lots of different species will affect the natural order of balance and will most likely affect us too, like our fishing industries. It's not a very useful tool for commercial fishing since they throw away about 82% of their catch anyways. They should find another alternative that won't demolish the marine ecosystem since what they are doing is more harm than good. If this continues, it will backfire on us and we'll find ourselves in a situation where our own resources that rely on the ocean are completely gone.

But when we say this, this would guarantee that we would need to stop trawling in Alaska which would not go the way that we would hope for. But coral is not the only issue that trawling is facing. Wasteful fishing is also a major problem environmental wise not only are we killing major housing for fish we are also killing huge amounts of other species that the environment relies on. One of the fact that really caught my attention was that deep sea trawling catch up to about one million pounds of coral every year. This information has some interesting facts on trolling. But stopping trawling would be a bad idea. not only is it a major way to catch fish but it is also jobs for people and a lifestyle that they enjoy and would not appreciate stopping trawling. They already sectioned off spots for the scientists to observe and study the coral but if they are this concerned about it they should consider sectioning off more of the coral areas and repopulate but not to much that the fishing industry would be affected.
