Essay about Raising Fish in Fish Farms

practice in the fish industry and provides a method of standardization for something as subjective

When ever you go to the beach, do you ever think about what can happen to an animal and the water when you leave a wrapper in the sand or a plastic bottle in the water? If you think about it, even a small piece of plastic can harm a fish. The fish could mistake it for food. This could potentially kill the fish. There are other things that people d that pollutes the ocean. An oil spill from a boat can get fish sick (Doc.2). Also, solid waste, plastics, glass, and foam (OI). Marine life can get trapped in any of these items (OI). There are many things we can do to prevent this, like, reducing plastic waste in stream, improve solid waste management, and increase, capture, and reuse (Doc.1). These are just a few of the many things we could do to

There are also some negative effects that fishing has on the environment. Destructive fishing practices devastate the marine environment and include bottom trawling, bycatch, the use of poison and explosives, and ghost fishing. The larger and better equipped boats mean the more devastating the impact of illegal fishing techniques. Bottom trawling is an industrial

One of the most commonly shared beliefs about aquaculture is that it has potential to amplify and transfer disease/parasites to wild fish populations, but strict management practices and guidelines have been utilized and supplemented to ensure that US farming operations mitigate current and potential environmental risks associated with aquaculture (NOAA, 2015). Among these practices are regular diver-led inspections to investigate the integrity of nets and net infrastructure, surveillance cameras and even public webcam feeds that monitor the fish farms and in particular monitor efficient use of feed, regular health inspections in efforts to have a head start on disease prevention and detection, and “comprehensive sanitary and biosecurity programs to prevent the introduction and/or spread of pests or diseases from one farm site/cage to another or into the environment.” (NOAA, 2015). Additionally, movements are being made to stop the spreading of disease and to limit oceanic pollution by containing salmon in solid tanks rather than in netting. “In Washington State, Domsea Farms has launched a land-based, freshwater system to produce coho salmon.” (David Suzuki Foundation, n.d.) This method is not only environmentally sound, but it opens up aquacultural boundaries. By containing fish in these large tanks, there is potential for salmon aquaculture to

But the effects that it will have on ecosystems could be catastrophic. The lack of protection on beavers’ home could possibly lead to extinction in these animals and the dams beavers’ create slow down the river's currents and make the water more habitual for many fish species. Which resurfaces the fact that all species depend on each other to create an ecosystem. The length of the rules in Minnesota’s fishing regulations to protect the fish, in the long run, will not protect the species that help fish thrive within an ecosystem

We need to decide if we want the economic benefits or if we want to save our ecosystem for the future generations to enjoy. Spotted bass are being considered an invasive species by some biologists. In 1993 a group of biologists in Louisiana put tracking devices in spotted bass to try and learn more about this species that was becoming more prevalent in the Flint river. The same group of biologists did a follow up electro-shock in 1999. The electro-shock showed that this population of bass was growing at an extremely rapid rate. The population of these fish had more than doubled and the other fish species had decreased, especially the largemouth and smallmouth bass. There was another electro-shock done in 2005 that showed the same results. The spotted bass population was growing rapidly and the largemouth and smallmouth populations were dropping. A different group of biologist decided to follow up on the studies that were done in earlier years. They found that the largemouth populations are struggling and the smallmouth are no longer in the Flint river. According to North American Journal of Fisheries Management, the recent introduction of spotted bass along the upper Flint River has caused great concern among anglers and fisheries managers about the potential negative impacts.

They have been trying to restore the walleye population by making it so that citizens can only keep 1 fish which is mostly in the winter and you never know how many people are keeping when they are in their fish house or they make it catch and release in the summer and sometimes close it to walleye. So I believe that the netting isn't the only reason that the walleye numbers have been declining but I don't think that it helps the numbers very much. I believe that the netting while the walleye are spawning should either be stopped or they should make them wait until the walleye are towards the end of their spawning and that the DNR should enforce

“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.

The population of many fish species have decreased drastically through the years and, even with current regulations,

Don’t you want he plants and animals living in the lake to have a healthy environment so they do not die off? With pollution it causes algae blooms to form. When algae blooms form, they can release toxins that can sicken and kill animals that live in the water. Fish die from having so much pollution. Would you want your environment to be polluted so much that you die? Just because fish are animals does not mean that they get less respect.

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

The Bluefin tuna, which has been endangered for several years and has the misfortune to be prized by the Japanese sushi lovers, has suffered a catastrophic decline in stocks in the Northern Pacific Ocean, of more than 96% (“Overfishing causes Pacific Bluefin tuna numbers to drop 96%”, 2013). For a long time, Bluefin tuna have been a worldwide problem. It seems that nobody really wants to stop it, it seems that people put little effort into a major problem. One Bluefin tuna sold in Japan for more than £1m, reflecting the rarity of the Bluefin tuna and the continued demand for its fatty flesh (“Overfishing causes Pacific Bluefin tuna numbers to drop 96%”, 2013). An interesting fact from this newspaper was that “more than nine out of 10 of the species recently caught were too young to have reproduced, meaning they may have been the last generation of the Bluefin tuna” (“Overfishing causes Pacific Bluefin tuna numbers to drop 96%”, 2013). Amanda Nickson, of the Pew Environment Group said “There is no logical way a fishery can have such a

Another global effect of overfishing is fish farming or aquaculture. It was first started to help preserve the ocean and hoped to help people to obtain a reliable fish source. Unfortunately, what many came to realize is the downside of fish farming. One example is water contamination, where consequently waste products such as foods eaten, feces and other dead fish, are all dumped into our main water supply which contributes to water pollution. Moreover, chemicals that are used to treat the fish farms like antibiotics and algaecides are all released into the ocean; which is a real cause for concern for our oceans. Fish that come from the fish farms are pumped full of drugs, to prevent sickness in the fish but this is not healthy for us to eat. There is also a great environmental impact which includes the fact that to sustain fish farms, portions of

Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.

In today’s global economy sustainability is very important; from the biological aspect to the industries they all play a role on the marine environment. As world population increases the demand of fish rises causing overfishing. Certain laws have been placed to limit the amount of wild fishing to reduce the risk of endangerment. To meet the demand of the population, fish farms are introduced. Pollution and health related issues are part of the challenges of fish farming. Sustainability also affects social areas such as beaches.
