Yes, the biological method is appropriate because these methods/processes because they potentially allow for the strain of depleted wild fish populations, allowing depleted fish stocks and ecosystems to recover, whilst delivering food and valuable nutrients to millions of people. (14).
Although, aquaculture is the fastest growing sector of food production in the world and is often viewed and suggested as the future of the fish industry, in its current state it’s not a solution to overfishing. (22).
To contrary belief aquaculture does not relieve the pressure on wild fish species, and some cases it increases it. Intensive aquaculture is one of these culprits, the high concentration of fish means that parasites and diseases can spread easily, although the fish being farmed are selected for their resistance to such things, but this often only due to great use of antibiotics and vaccines. However next to non-aquaculture environments, causes local fish to suffer immensely. Recent research that was undertaken around a single fish farm (salmon) in British Columbia (Canada) has produced lethal sea lice at rate 33,000 times normal levels, and subsequently generating deadly infections of young wild salmon up to 70 kilometers away. (22).
There are also many other factors that put pressure on wild fish species, these include: in numerous fish farms vast quantities of forage fish, fishmeal and fish oil are used to feed the farmed fish, this results in more fish being used to feed the fish than the quantity produced, meaning the pressure on wild fish stocks remains high. (22).
There is also a chance that fish may escape from the farm; these fish are generally selected for their characteristics, which make them unsuited to reside in th...

...populations, some countries have invested into fish farming or aquaculture, but some controversy has followed from this practice. Studies have shown that fish farms are not helpful in sustaining the native fish, and have actually harmed them instead. There are two main types of aquaculture: onshore and offshore. These farms, often times due to overcrowded tanks, result in outbreaks of deadly diseases. An example is pop eye, an eye infection that causes swelling of the eye. On offshore farms, domesticated fish often escape through faulty and inferior netting, infecting native fish populations. Alternatively, offshore farms pose a different problem. Management of these facilities has been known to filter pure excess waste products of the fish into the ocean. The contaminated water, also full of nutrients, creates algae blooms and starves sea floor of sunlight.
As the United States population has increased 75 million to 317.9 million humans in hundred years. So has the demands from seafood increasing as well. Americans consumed 4.5 billion pounds of seafood a year. The company of AquaBounty Technologies has been trying to create a product to combat the grow demand to produce enough seafood with crippling the wild fish population. The company created a genetically modified Atlantic salmon as a solution for the problem .The genetically engineered AquAdvantage Atlantic salmon grows twice as fast as regular salmon. In order to get the Atlantic salmon grow twice as fast the received growth hormone into fertilized salmon eggs. This allows them fish to produce year-round. AquAdvantage genetically engineered Atlantic salmon has product been approval by Federal and Drug Administration for human consumption. As a representative for the Center for Food Safety, a U.S. non-profit organization that works to protect the environment and human health. I evaluate elevated the AquaBounty Technologies product of genetically engineered AquAdvantage Atlantic salmon on the criteria healthy for humans, feeding practices, and environmental impact. I determined that Center for Food Safety will promotes repeal of the FDA approval commercialized sell of genetically engineered salmon.
Overfishing is a major problem in economy today. The practices of fishing too much or too often result in a decrease of the fish population. Constant removal of fish from the oceans (fishing) accounts for both adult and baby fish. With the consistent decrease in adult fish, mating becomes more difficult or even impossible, resulting in an overall lack of fish in the oceans. Pepijn Koster defines overfishing as, "Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans." (par.1). When fish stocks cannot be replenished faster than they are being depleted, a reduction in fish population occurs, which is what is referred to as overfishing.
Countries, fisheries, and consumers all need to share the responsibility for conserving endangered marine life. First, governments should base their policies on scientific factors and should look for better economic incentives to stop fisheries from overfishing. Second, fisheries should use methods that are not so destructive to the fish population. Finally, consumers should avoid buying endangered seafood, even if they have to pay a little more. If these parties recognize that it is worthwhile to conserve marine species, then they must accept this responsibility.
Eric Dunne Consulting Initiatives (2010) aimed at examining direct sales of fish by harvesters in an effort to provide directions for regulation and monitoring to accommodate the needs of harvesters and consumers and to protect public health
One of the sectors facing the largest impact is the seafood industry. Fish products are prevalent in pet food products as well as human diets. Given such a high demand on the seafood industry,
Overfishing refers to an act of fishing more than what the population can replace through normal reproduction (WWF, 2016). This was led by international government efforts to increase fishing capacity in the mid-20th century, which then led to the increase in availability and affordability of protein-rich foods. With this, profitable commercial fleets became aggressive, scouring the world’s oceans and developing sophisticated technologies to find and catch their targeted species. Thus, with a wide selection of fish species available at affordable prices, customers soon became used to them (Geographic, 2016).
British Columbia is the fourth largest aquaculture producer in the world. The province and everywhere else that loves seafood relies on the production of aquaculture. However, many do not know what they get when the glory of farming fish comes with. Salmon is one the most common fish and British Columbia wanted to make sure that who ever wanted it could get tons of it. While global warming has been driving wild salmon stocks up north, British Columbia came up with their own solution, Aquaculture. It was the perfect thing due to the fact, British Columbia has 20,000km of coastlines and 25,000 lakes and many rives and streams to raise fish. This became an advantage to fish farmers and aquaculture heads because the plentiful water allowed them to raise wish in any body of water. The economic benefits came pouring in as fish farmer could grow many fish all year round and have control of it. The salmon in these farms are raised in pens, just like you would see animals on a farm on land. B.C’s fairly clean waters, sparse population and accessibility to roads makes it well suitable for the fish to be raised from hatchlings to harvest. The net pens that held the salmon year round were limited to small spaces, developing some major issues in the ocean’s health and human health. Many have blamed farmed salmon for the sea lice. Sea lice have been depleting lives of many wild salmon as farmed salmon are allowed to escape from their nets into the ocean. Allowing the possible spread of sea lice. Sea lice are crustacean parasites that attach onto both farmed and wild salmon. These parasites do not kill the fish, however they drain the resources the fish need to survive and decrease their ability of swimming. The sea lice also create open abrasio...
The primary areas of concerns entail not only local nutrient pollution into water systems, via waste feed, but feces, as well as, chemical pollution, with chemical and antibiotic treatments, and the spread of diseases via farm escapees to wild fish populations. According to Farmed and Dangerous.org (n.d.), salmon farming remains one of the most harmful aquaculture production systems. due to open net-cages maintained directly in the ocean, hence producing farm waste, chemicals, disease and parasites , which flow directly into the neighboring waters, harming other marine life, such as industry, as sea lions and seals. Furthermore, farmed
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.
To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
Unless the current situation improves, stocks of all organisms that are currently fished for food are predicted to collapse drastically by 2048 (WWF 2.) Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more
The rate of aquaculture production is increasing all around the world as a result of the growing demand for fish as an important food source and due to depleting the production from capture fisheries (Subramanian, Shariff, Omar, & Hair-Bejo, 2012). Given the richness in aquatic resources, the fisheries sector in Sri Lanka comprises of offshore, coastal and freshwater fisheries as well as coastal and freshwater aquaculture. It contributes around 1.7% of the total GDP and provides direct and indirect employment to over 500,000 people in coastal communities around the country. It is the main source of household income for an estimated 2.5 million individuals, equivalent to 8% of the population and plays
