Advantages And Disadvantages Of Aquaculture

Many economic concerns have been brought up due to the harvesting of timber, mining and reservoir operations. Erosion has stripped the thin soil cover and caused silting of streams. Reservoir operations disrupted fisheries by changing the temperature and the patterns of the streams and how they flow.

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

The worlds biomes at the moment are unable to feed the growing global population in the future. They might be able to feed the population now but as the population grows we need to increase the worlds agriculture to provide enough food to feed the growing population. In order to feed the growing population, the world needs to put into action some simple steps to increase food production and to reduce wastage from existing food.

“Seafood is a good example. All the seafood we source here is sustainable, such as salmon and cod. We’ve also, however, started to work with local fisherman to use underutilized fish. That is, buying fish that would otherwise be considered by catch and never brought to market. So, for instance, redfish or pollock. We’re introducing students to these fish in order to make them more acceptable and mainstream.”

Planet Shrimp wants to use ‘clean’ shrimp as their main point of differentiation, highlighting their closed-loop aquaculture process that does not involve toxins and ensures environmental sustainability throughout. As consumers are continually concerned about knowing where their food comes from, the safety of their food and price point, Planet Shrimp should understand how to educate the public about the ‘clean’ shrimp movement (The Canadian Press, 2014a). To achieve this, Planet Shrimp must answer the question:

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

The ocean makes up nearly three-quarters of the planet 's surface and contains about eighty percent of the life on earth. Millions of people all over the world depend on seafood heavily as a primary source of food. Americans alone consumed as much as 15.8 pounds of seafood per person in 2009 (NOAA). This is a lot of fish. In fact, it is so much that many populations of fish are going extinct. At this particular rate according to National Geographic, scientist predict that the earth is expected to lose all of its current fisheries by the year 2048 (Roach). The overfishing of our oceans leads to unmanageable practices that will eventually cause many species of fish to become extinct.

Overfishing has been challenged by the rise of fish farming, or aquaculture, which allows popular fish such as salmon to be raised on farms. Aquaculture does help prevent the depletion of wild populations at an unsustainable rate, although the practice has its own issues. The process of raising fish on a farm raises ethical and hygienic questions, due to the fact that farmed fish normally grow up and live in cramped tanks or ponds their entire lives, and if not well-maintained, such environments can become filled with fish excretions, bacteria, and diseases that can then infect the fish. This issue is not present among wild-caught fish, which reside in large bodies of water or rivers that prevent a similar health and safety risk for people consuming the

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.

The current global population of 7.6 billion people is expected to reach 11.2 billion in 2100 (UN DESA), and as the Earth’s population continues to grow exponentially, the topic of environmental sustainability is being debated with increased urgency. In the past few years, many large-scale environmental issues have emerged due to human activities: climate change, air and water pollution, rising sea levels, habitat loss, species extinction, and worsening natural disasters are all becoming more and more prevalent. But perhaps our most immediate concern should be whether or not we will be able to continue feeding this ever-increasing population.

The world has been industrializing for over a century, leading to better lives for people everywhere. Unfortunately, industrialization often results in an overuse of resources that can often have unintended consequences. In today’s world, industrialization of the fishing industry has led to a rapid decline in many fish species. This is due to a number of factors, ranging from changing ocean temperatures, acidification and degradation of many natural habitats fish depend on, to poor measurement of current fish populations. The main factor in the decline of fish populations worldwide, however, is overfishing on a massive industrial scale. The decline of fish populations could have massive consequences for ocean ecosystems and could result in shortages of fish many communities have grown dependent on not only for food, but to support their local economies. In order to find the best solution to the rapid decline in fish populations worldwide, evidence must be analyzed relating to the environmental, economic, scientific, historical, and futuristic lenses.

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

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

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.
