Pros And Cons Of Fish Farming

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

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

Now days times have changed. You can no longer enjoy the things you once could. It has become dangerous to waterski or to even enjoy a boat ride down the river due to the Asian carp. These fish are startled easily by boats, and small watercraft. They can jump ten to twelve feet out of the water causing damage to boats and injuring humans. I have heard of people getting cuts from the fins, black eyes, concussions, broken noses and jaws, and even knocked unconscious from this species of fish. Not only are these Asian Carp causing physical damage, they are wreaking havoc on the ecological system. The main concern from the Asian Carp is the dangerous effects that it is bringing to our ecosystem. As an avid fisherman, this is of great concern to me. This will not only affect me as a fisherman, but also possibly hunters, bird watchers, boaters, even jet skiers and water skiers are

Pesticides and preservatives are not only harmful to human beings, but they are also harmful to our environment and ecosystems. Pesticides used in organic farming may run-off and contaminate nearby bodies of water. If enough contaminated run-off from pesticides and artificial fertilizers get into water, it is able to poison animals and fish that live there. According to Raloff, recent studies have demonstrated that exposure to hormones has a substantial effect on the gender and reproductive capacity of fish, throwing off the natural cycle, (1). This is not only harmful to the animals that live there, but if enough fish are dying because of poisoned run-off, the fish industry could suffer and it will affect humans as well. The same chemicals that poison bodies of water could seep into our groundwater and affect the well water we drink and use daily. This does not happen with organic farming, because no chemicals are ever sprayed on the fields and there is much more run off because of tilling practices.

There are many risks associated with eating farm-raised salmon versus wild- caught salmon. One risk that farm raised salmon faces is contaminants that can lead to cancer. Farm raised salmon are placed in artificially made bodies of water such as ponds, lakes, and salt water and within these bodies of water, contaminants such as PCBs can be present. Cancer causing chemicals can be present in both the water, farm-raised salmon swims in, and the food they eat. Another risk with farm-raised salmon is the use of antibiotics in order to keep the fish healthy. This unknown amount of antibiotics used on the fish can lead to a resistance to the antibiotic used to kill the bacteria’s in both human and the salmon. The humans that are consuming the fish that possess these antibiotics are unintentionally

Anyways it’s not like fast food fish sandwiches are required for us to survive. Also fish is wasted very frequently, it expires or is not eaten, so that is just harming our resources for no reason. People need to realize that fish is important, but could be used in a much smarter way. Many are reasonable and try not to be wasteful, but too many people are. Undoubtedly, if we continue this pattern of wastefulness with our ocean's resources there will be consequences. Many statistics and facts back this up. The rules and regulations we are putting on commercial fishing simply aren’t getting the job done. Our ocean’s fish population has declined so much in forty five years and the overfishing by commercial boats hasn’t gotten better, just worse. Remember the fate of the ocean’s resources is in our very own hands. Works Cited "The Threats of Overfishing: Consequences at the Commercial Level." DUJS Online. N.p., 29 May 2012. Web. 23 Mar. 2017.

The Sacramento-San Joaquin Delta supplies almost two-thirds of the state with water. Many plants and animals live in the Delta. One of them is a tiny three-inch fish called the Delta smelt. It is due to the endangerment of this fish that the pumps that supply many of the farmlands in the state with water to grow crops were shut off. The fish were getting caught in the pumps. This caused the environmentalists to file a suit to get the pumps shut off. When the suit was won it was hard blow to the farmers. Having to worry about getting enough rain every year is enough of a burden to them. Now the water they need to grow crops was shut off for a fish. Humanity is more important than a tiny fish.

Before the practice of fish farming even came to play, other factors were already contributing to the decrease in salmon species. Overfishing is one major reason to why there is low levels of salmon because of the immense demands of customers and in order to reach the supply for them, individuals and large companies of boats are taking in these fish in vast numbers with certain ways of innovative fishing. These include using longline, where there is an extended line that are made up of hooks, and nets that are spread across an area where fish may be. Not only do these styles of fishing catch hundreds of salmon but they often catch bycatch as well that affect all other populations of fish and even foods of what the salmon eats like shrimp. Two other ways that are affecting salmon involve the loss of its habitat and the uses of water-powered dams which are part of the methods of affecting the environment. The loss of habitat comprises of pollution in and around the area of freshwater, including chemical waste from industrial sites and the change in the flow of rivers due to hydroelectric dams that favor the human population needs. As a result of these obstacles and barriers, flowing waters have a lack of nutrients and can reduce the diversity of the freshwater environment which could lead to low resources of food for the salmon. With all these environmental issues that

Do you like to visit Lake Erie? Of course you don’t! The water is so unsanitary from pollution. Well, the fish feel the same way, and that is their environment. Many people think that washing down products with chemicals in them will not harm anything.Well, it does. The water dumps into Lake Erie. Then with all of the chemicals, the water starts to get polluted along with the animal’s environment. Fish deserve a healthier environment. Just because fish are animals does not mean that they should live in unhealthy water.

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.

Overfishing’s status as the focus of public concern mainly results from its negligible but harmful influence on individuals, collective, and even the whole world. One of the world’s significant fishery in the East China Sea is damage by overfishing and growing levels of contamination, recent research has shown, confirming the fear of fishermen and environmentalists.

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

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

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

Pollution is a damaging with fish farming. A group of wild fishing being fed to fish in the ocean will eventually transfer disease. As well, fish pollute the water from their wastes. Fish farming also affects the growth and genetics of the fish because they are not in a wild environment. More research should be completed to provide more adequate information and prevent negative outcomes for fish farming.
