Aquaculture
Aquaculture is a form of agriculture that involves the propagation,
cultivation and marketing of aquatic organisms in an controlled
environment. The history of aquaculture first begun in ancient China
some 4000 years ago with ornamental carp ponds to today's $264 million
commercial production of catfish in the southern states of America. 1
The following essay will be a broad examination of the conditions and
requirements of aquaculture and a closer study of the industry in
Western Australia. It should be noted that the industry is only at a
fledgling stage with a handful of organisms in commercial production.
However, there is one segment that is a major success with $153
million worth of merchandise a year. 2 This of course is the Pearling
Industry in the northern part of the state.
The scope of this essay is to study those other sections of the
industry within the state that displays some potential to be
commercially viable in the mid to long term.
Water Sources
Water supply is the most important factor in selecting the location
for an aquaculture facility. Aquatic organisms depend upon water for
all their needs. Large quantities of water must be available year
round.
Water sources can be classified into several categories some of which
are wells, springs, groundwater, streams, rivers and lakes. Wells and
springs being the best sources because of the high water quality and
uncontaminated condition. 3
Water Quality
As mentioned above, water quality determines the success or failure of
an aquaculture operation. Therefore it is imperative that when in a
commercial enterprise, the key factor - s...

Since three-forth of the world is composed of bodies of water, it’s natural that a great number of people rely on fishing for their livelyhood or just for their recreation needs. There are numerous of fish species swimming under the lakes, seas, ponds, and rivers. Most anglers consider fishing as the delight in their purpose-driven life, a sport, as they say.
Blue crabs have the highest value of any Chesapeake Bay commercial fishery; in 2000, the blue crab harvest was valued at a staggering $55 million (Blue Crabs – Chesapeake Bay Program). For Maryland locals, the importance of crabs during the summer months is bigger than any other issues; summer days are spent at picnic tables picking away at the hard shells of the steamed morsels. During these months, commercial fisherman are up before the sun rises, riding along checking their lines and baskets in the bay in hopes of a good yield of the crustaceans to bring back to sell later that day. In fact, an estimated one third of the nation’s catch of blue crabs come directly from Maryland’s own Chesapeake Bay (Blue Crabs – Chesapeake Bay Program).Therefore, sustaining the population of crabs is essential in the success of the businesses that rely on the income from selling them, and also to the people who consume the crabs frequently. At the same time, the constant pressure on harvesting the crabs for income has created an issue. Since the early 90’s, yield of crabs has decreased, resulting in an increase of efforts to meet the demands of the business of co...

Salmon Farming If you recently ordered salmon off the menu of your favorite restaurant, or purchased it from your local grocery store, chances are it was farmed. According to “Salmon of the Americas, an organization of salmon-producing companies in Canada, Chile and the United States, 70 percent of the salmon produced in British Columbia and Washington comes from salmon farms. If it weren’t for these farms, we would not have the luxury and abundance of this delicious and healthy food available to us year round. Salmon farming represents one very important way to feed the world and people want to eat more salmon and seafood- more than can be caught.
However, Japan, one of the first countries to develop salmon hatchery program, as well as, an extensive aquaculture program receives the major credit for Japans eighty percent overall salmon production in the 1990’s. Moreover, this form of aquaculture is a principle source of fish not only in the United States, but also globally with China, now being the world’s largest producer with fish. Although, the practice of salmon aquaculture were thought to have developed via the Danish system of raising rainbow trout in freshwater
Hundreds of years ago, people migrated to the United States from many European countries. As time passed, America received even more immigrants from many different cultural backgrounds. Unlike some other countries, if you walk around in the United States, you will see people of all different cultures. This is the reason our country is described as a, “melting pot.” Though everyone that lives or has lived in America is considered an American, some of their ancestors that did not migrate to America, were not. So, the culture of these ancestors travel through generations, & give later family members a share of their decadence. When a couple has a child, their children have a mix of both parent’s blood, giving them multiple ancestors of different cultural decadence. The passing of cultures is why I’m able to say that I’m not only American, but I am also English, French, & German. Though many people who have different backgrounds do not practice the customs of the
With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
The topical focus of this paper is the Atlantic salmon fishery. In particular, this paper looks at habitat loss and salmon farming both of which have had major impacts on the sustainability of the fishery. Several efforts have been made to restore Atlantic salmon to their native habitat, specifically in Maine and New Hampshire. This paper reviews the policies that have been implemented, not yet implemented, and a proposed policy.
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 ...
Aquaponics produces the biggest, best, and most diverse fruits and vegetables in the smallest amount of space. Unlike normal gardening and farming, Aquaponics is not limited to seasons or climate, which means all types of fruits and vegetables can be produced year round. When farmers can produce any plant, any where, at any time, the produce can be picked at the peak of its ripeness, which is when it looks and tastes the best, and since farme...

Aquaponics is the combination of both aquaculture, which is fish farming, and hydroponics, which is farming without the use of soil. In aquaponics, plants form a symbiotic relationship with fish allowing for fish to get nutrients from plants, and plants get a supply clean water from the fish. With aquaponics, the plants and fish can grow faster than average due to naturally fortified water from the fish, and nutrient-rich water from the plants. Aquaponics also allows for two types of farming happening at the same time, fish and plants, if the system the fish are in is large enough. Furthermore, aquaponics allows for plants to grow anywhere, without arable land. Many countries are not able to meet the demand for food because of the climate or
Above all, these organisms encourage the growth of algae, which absorb dissolved oxygen in the water essential for the survival of fish populations. Occasionally, the decomposition of newly-submerged biomass and sediment further reduce the water's oxygen content. Water sources can literally choke to death as a result of increasing human activity, such as industry and agriculture giving rise to increased nutrient loading.
