Ocean Problem : My Solution

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

Aquaculture can be defined as farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants both in freshwater and saltwater. It has a wide range of ownerships from small family business to multimillionaire global industries.1It provides many job opportunities throughout the world. As an example Canadian aquaculture industry valued $ 5 billion Canadian dollars provides more than 130 000 jobs only in Canada.2Accelerated growth of aquaculture causes series of problems to both human health and environment.3Most bacterial species resides both in animals and well as in human will pathogenic to both. transfer of pathogens between the two host species is a common situation for most organisms.4 Most of the developing country aquatic farms are non-hygienic and stressful. This will lead to an increase of bacterial infection among most aquatic species. As a preventative and curative method farmers mix a huge amount of antimicrobial products with the aquatic feed.5 Since aquaculture is a global industry, Implemented laws and regulations are different from country to country. It is very difficult to implement global regulations relating to antimicrobial use.1

Tipped to be the next 5 Seconds of Summer, Aussie band Little Sea isn’t your average boy band. In fact, they refuse to use that term. “There are definitely a lot of successful boy bands out there at the moment, which is why we made an executive decision a long time ago (before the band was really ever even a thing actually) to not be a boy band.” Shares Dylan Clark, bass player and pianist for the four-piece.

Fish, one of our most important sources of high-quality protein, provides some 16% of the animal protein consumed by the world’s population, (Food & Agriculture Organization, FAO, of the United Nations, 1997). Our responses towards a growing demand for fish led to a boom in the salmon farming industry (Naylor, et al., 1998). Unfortunately, the consequences of salmon farming outweigh the value that comes with it. Even though salmon farming is steadily becoming more sustainable, salmon farming is not a suitable and environmentally sound way of producing food due to the negative issues salmon farming has caused in the environment, the salmon population, and the health of humans.

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.

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

Commercial Fishing has always been a means of making a lucrative living. So much so, that is one of the reasons that concerns have risen today. With the increase in the number of commercial fisherman within the U.S., it requires more fish to be fished from the seas. Over the years, changes in the fish stock population has become a serious concern. Commercial Fishing is also destroying our sea beds and marine life that lives on the sea floor of the oceans. Many times, the threats to marine life due to commercial fishing are not detected until the marine life has suffered a significant decline in numbers. Unless other practices are put in place, the impacts of regular fishing spots, bottom trawling and pollution will have a catastrophic

“How to Farm a Better Fish” by Joel K. Bourne, Jr. was published in National Geographic’s June, 2014 edition magazine. This particular article characterizes the differences between the various types of aquaculture, as well as what species to feed and the ingredients that make up the food given. The reporter who composed this editorial informed the reader of the advantages and downfalls of an indoor fish tank vs. an outdoor fish pen. The reporter pointed out the numerous ways an aquacultural company may feed their harvest of fish. He even explained that some fish farms have a whole ecosystem of aquatic animals and plants that they feed instead, to supply the whole food chain with enough nutrients. This is a rather important article because

Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.

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.

Aquaponics is the process of integrating aquaculture, fish farming, with hydroponics, growing plants in water. Since use of unnatural products such as chemicals, pesticides, and herbicides could potentially harm either the fish or the plans,

Two Ponds (P3 & P4) lined with tarpaulin sheets were selected for the experimental culture having depth range of 1.30 & 1.25 m respectively. The pond measurements like Top & bottom width, surface area, pond name, and species stocked, stocking density and days of culture were prescribed on the display board at one corner of the pond. The pond was allowed to dry for 30 days. The pre-stocking management (Fig-01) practices were adopted as per the standard procedure follows as drying, desilting, bio-security measures
