They are high in protein, have complex carbs, lots of micronutrients and can be whipped up into a wide variety of delicious dishes. It is no wonder that beans are the staple food of so many cultures around the world. Rice does have plenty of good macro and micro ingredients but it is nothing to write home about.
It has greatly benefited the seafood business and has allowed consumers to have traditionally seasonal fish at any time of the year; however as the aquaculture industry rapidly grows from small scale to large scale, many question its sustainability. While the industry insists that fish farming takes the burden off wild fish stocks, other experts have suggested that the farms actually do more harm than help by increasing the spread of diseases, parasites such as sea lice, and astronomically increasing the level of pollution and Fish farming 2 essay in the wild ecosystems.
In particular, the large scale production of carnivorous fish such as salmon has concerned many environmental groups because it requires much larger amounts of resources than producing other types of fish.
Escaped salmon from farms can also adversely affect the genetic variability of wild populations, reducing Fish farming 2 essay ecological resilience. Rising evidence suggests that fish farming may end up taxing the environment beyond its capacity if it does not become more ecologically mindful.
Technology optimists believe new innovations can resolve any possible hurdles that may come about with the development of aquaculture.
Sinceseafood production in the aquaculture industry has increased at an annual rate of 8.
As the world population approaches 8 billion, seafood producers have harnessed aquaculture in an effort to fill the gap between population growth and natural seafood production Molyneaux 28— Farmed salmon production amounted totons in and increased fold since Morris et al.
While shrimp and oyster farms mainly grew out of developing countries, salmon farming grew out of countries with access to more sophisticated technology including the U. Initial assessments of fish farming concluded that all economies had an interest in developing aquaculture. For example, on June 2, in Kyoto, Japan, an FAO Technical Conference on Aquaculture examined and discussed types of aquaculture, the possible problems such as the risk of disease, and ultimately recommended the expansion of aquaculture, leading to huge investment in the rising industry Molyneaux 30— To technology optimists, the potential rewards of aquaculture seemed infinite, but few stopped to consider possible repercussions to the ecosystem.
Some environmental concerns about aquaculture did surface as it began to develop, but any initial fears of ecological impacts did little to inhibit growth of the industry. In the United States Congress established the Commission on Marine Science, and in the commission released a report that called for more research on aquaculture.
I originally introduced the term “orthorexia” in the article below, published in the October issue of Yoga Journal. Some of the things I said in the article are no longer true of me, or of what I currently believe. IELTS Writing. Graphs: Learn how to write about about graphs and charts. Good for Task 1 in IELTS writing. Argument: You have to give your opinion in a short essay on a subject. Great for IELTS Task 2 Writing or TOEFL. If the fish wernt cramed togher in a small place desease wouldn’t as big a problem. although it would still take a lot of wild fish to feed the farm fish. there shouldn’t be dye in the farmed salmon, so what if it’s gray it’s still salmon.
Despite the lack of research, the promise of jobs and food security outweighed any concerns about its effects on the environment, and development continued unabated Molyneaux In addition, the passage of the U.
Aquaculture Act in also helped nurture the development of the aquaculture industry Molyneaux Fish farming has obvious benefits such as food security and jobs, but these obvious benefits obscure many of the potential problems that could arise in the future.
An industry such as aquaculture that does not make efforts to promote sustainability will inevitably run into problems, despite any short term benefits it may give to investors.
This process requires a huge amount of resources compared to herbivorous fish, making the salmon industry more vulnerable if supplies become scarce and much more energy intensive. The question of whether aquaculture provides a sufficient food source for future generations means many companies will lead themselves to failure if they do not manage their resources responsibly.
Does aquaculture pose a risk to wild salmon? Supporters of the industry would argue that aquaculture takes excess burden off the wild stocks that might otherwise become dangerously depleted.
Wild salmon have particularly felt the impact of commercial fishing in the Atlantic and Pacific waters. Aquaculture came about as a possible solution to the problem and would give wild salmon an opportunity to rebound from endangerment due to overfishing.
It has been proven successful with other types of seafood such as catfish and tilapia; however, some have contested that serious problems associated with fish farming have put potentially much greater pressures on the wild populations of salmon Claiborne 1.
This report provided a preliminary look into the effects of farmed salmon on wild salmon and demonstrated that farmed salmon have a significant prevalence in wild habitats. Such escape events call for greater monitoring of farmed salmon production. Some areas have made more efforts to do this than others.
Keeping track of escape events and how many salmon find their way into wild habitats helps identify the risks posed by aquaculture and to what extent they affect the ecosystem. As production in aquaculture exploded, disease became the defining issue that could impede or even kill its expansion.
Infectious salmon anemia ISAwhich began to affect farmed salmon in Maine, became a serious problem and resulted in the destruction of 1. The aquaculture industry has not yet come up with a standard method to approach the problem of disease.
ISA spread through many pathways such as sea lice, gulls, and sloppy disposal practices Molyneaux The negligence of the aquaculture industry to use more caution in managing its supplies could have led to its abrupt failure and should serve as a warning to fish growers that ignorance of proper resource management has high ecological and economical consequences.
Outbreaks of viruses such as ISA led to the rapid establishment of programs to eradicate them. Vaccines did help the industry gain control over many diseases that had hindered its development in the s; however, vaccines can create other undesirable consequences Molyneaux In the case of salmon farming, vaccines prevent the fish from showing symptoms but do not protect them from infection, which effectively hides the problem instead of curing it Molyneaux The Ultimate Burrito has all your nutrients from 9 whole ingredients in the most cost effective, time efficient, and environmentally friendly form.
With further research in aquaculture, especially on production of fish seed and fish feed technologies, aquaculture in heading towards a quantum jump in years to come. Organisation of aquaculture. How to Farm a Better Fish. In a dark, dank warehouse in the Blue Ridge foothills of Virginia, Bill Martin picks up a bucket of brown pellets and slings them into a long concrete tank.

Video editing by Max Tiberi. The World Wildlife Federation emphasizes that temperature increases of 2° Celsius or more are dangerous for fish. Healthy water temperatures differ according to species. Scientists link increased water temperatures to global warming, because water absorbs heat trapped by .
Fish farming is a form of aquaculture which involves raising or culturing fish. usually for food in a given body of water such as a pond, lake or reservoir.
