Essay On Fish Feel Pain

3. What did further examination of Tiktaalik’s fins reveal about the creature and its’ lifestyle?

Behavioral Biologist at Edinburgh University, Victoria Braithwaite in her article, Hooked on a Myth, Published in Los Angeles Times 2006, addresses the topic of “fish have feelings”, and argues that we should adopt new ways of fishing. She supports this claim by the behavioral studies and experiments, as well as the examples and similarities the fish have with humans. She adopts a determined and passionate tone for her audience, the readers of Los Angeles Times and others interested in the topic animal justice.

As mentioned in the case description, tetrodotoxin is a molecule that blocks voltage-gated sodium ion channels. Describe the structure of a sodium ion.

I will say that as much as the expression “Canary in the coal mine” implies an early warning of danger in mines so does it in water too. In this case the fish directly helps us know the extent to which our ecological sphere is damaged, and helps humans to take the necessary precautions to save the environment.

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

Simply because fish don't have a significant way of expressing their pain, humans tend to ignore sympathy for them. I can only imagine a hook cutting into my lip and dragging me to a place where I couldn't breathe. That image alone makes me believe that fish suffer. Although fish may not have brains as developed as ours, they still have

“The world’s smallest porpoise is slipping closer to extinction…” (Malkin). This propoise is called a vaquita, and they are getting run into extinction because of drift nets set of a larger porpoise called the totoaba. A drift net is a large net that is placed underwater for catching fish. Michael Pollan, author of The Omnivore’s Dilemma, talked about destroying the ecosystem through farming, but he didn’t mention how it could happen through fishing, too. Fishermen should stop using drift nets to collect fish because they can catch the wrong species and destroy the ecosystem.

Lost fishing gear in the ocean is also a big culprit to the death of many sea animals. “Ghost fishing” is a cause

The book Your Inner Fish by Neil Shubin is an interesting novel that shows the evolution of some of our major structures through time. We all know about evolution and the monkeys but we never really looked in on evolution through “our inner fish”. The book was appealing because it helps to understand how we have come to be with some of the parts of our bodies we take for granted, like how we got our developed smell or our advanced color vision. Your Inner Fish is a good way to jump into the evolution of our ancestors and become more knowledgeable about where we came from.

The animal will be suffer like humans when Pi successfully caught the fish, he is going to kill it in order to eat; however, he cannot kill the fish by himself. Here is a quote why he cannot kill the fish. “I put the hatchet down. I would break its neck, sight unseen, I decided. I wrapped the fish tightly in the blanket with both hands. I started bending it. The more I pressed, the more the fish struggled. I imagined what it would feel like if I were wrapped in a blanket and someone were trying to break my neck. I was appalled. I gave up a number of times. Yet I knew it had to be done, and the longer I waited, the longer the fish’s suffering would go on!” (Martel p231). Pi was so kind and he is a Christian, so he is unwilling to kill the fish; furthermore, he has to kill the fish by breaking its neck, it’s impossible for him to done this. When the fish is suffering, they will be struggle. It’s similar to the human being. When human being are suffering like someone wrapped in a blanket and someone were trying to break his neck. Human will be struggled, they will try their best to revolt to alive. The fish had the same thought, they will try their best to flee away from the blanket to keep

b) Sharks try so hard to become unhooked that they end up suffocating themselves. Most of time the long lining is not meant to catch sharks but other species, and so then the Sharks are just thrown back to ocean as a waste. This process is call bycatch.

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

To many people are dying due to fishing. Canada has to make fish industries less deadly. Fishing industry has cost about 190 Canadian lives since 2000 and it has to improve its culture of safety, the Transportation Safety Board. The causes of fatalities in the fishing industries is that most fishers decide to fish when the weather is in or is going to be in a bad condition, workers have to fish in those conditions because they need the money or they are behind in their quota for the year. Also, sometimes the vessels do not carry a distress communication device. “In Canada, falling overboard is the second highest cause of fatality in the fishing industry,”. “The safety of fishermen will be compromised until the complex relationship and inter

When fish like salmon are farmed, often the fish are still kept in the ocean; however, they live inside of nets so that they are still contained. There are many ethical arguments based around these net systems because these nets pose threats to wild salmon. Captive salmon can escape from the nets, which allows them to breed with wild salmon. This can disrupt the natural gene pool of wild salmon. Farmed salmon have been shown to outgrow wild salmon when introduced into the wild, and typically have higher mortality rates, which would be poor traits to be introduced into the wild gene pool, (Hindar, et al., 2006). Unfortunately, with the invasive farmed salmon being introduced to wild populations from escapees of net systems, the recovery of the original wild salmon is unlikely, even if decades went by without more intrusive farmed salmon being present, (Hindar, et al., 2006). Another problem is that the nets do not contain wastes from the captive salmon inside, wastes such as uneaten feed, and feces from the fish are dispersed into the open waters of the ocean. Wild salmon can contract infections and parasites from captive farmed salmon in nets. A study indicated that these parasites, such as sea lice, and infections lead to high mortality rates in wild salmon passing near

These seals often play with fragments of plastic netting or packing straps, and end up catching their necks in the webbing. The plastic harness can constrict the seal's movements, killing the seal through starvation, exhaustion, or infection from deep wounds caused by the tightening material. While diving for food, both seals and whales can get caught in transparent nets and drown. In the fall of 1982, a humpback whale was tangled in 50 to 100 feet of net and washed up on a Cape Cod beach. (Wohi, 1994) It was starving and its ribs were showing, the whale died within a couple of hours. Along Florida's coasts, brown pelicans diving for fish sometimes dive for the bait on a fisherman's line. Cutting the bird loose only makes the problem worse, as the pelican gets its wings and feet tangled in "Plastics in Our Oceans." Woods Hole Oceanographic Institution (1994): n.pag. Web. 28 Mar 2012.
