Aquaculture
Aquaculture is a growing business and is increasing rapidly as populations rise and the need for food is increased. Aquaculture is the controlled cultivation and harvest of aquatic plants and animals. Aquaculture is beneficial to the world but Aquaculture in different parts of the world has affected the environment also. There are several different types of aquaculture such as Marine Aquaculture and Freshwater Aquaculture. Aquaculture consists of many different people with different professions ranging from high school diplomas to high levels of education such as 4 year degrees. Aquaculture has been around for centuries used in different cultures with different techniques. Aquaculture plays a very important part in today 's society

Aquaculture provides food and nutrients to millions of people allover the world. Fish provides key nutrients and proteins and it benefits people of all classes. Fish is full of nutrients that the human body needs. Fish is distributed to people less fortunate and by providing these nutrients to people it can fight hunger for thousands of people all over the world. In the United States, 80% of our fish is imported and around 50% of those fish came from fish farms. Aquaculture plays a big role on the environment also. Many species of fish are severely over fished by commercial businesses and they soon cannot meet the food demand for the world market. Aquaculture provides a stable supply of fish and shellfish for the world market and it also takes the stress of overfished populations. Aquaculture can benefit recreational fish such as bass and other very important ecological species and habitats. With the expansion of Aquaculture, it provides thousand of jobs for jobless …show more content…
Fish health technicians raise fish for the selling for food and recreational purposes. They study fish and shellfish to determine which is the best way to raise them. Some technicians produce animals that can be sold to zoos, aquariums and pet stores. Marine Biologists are also needed in Aquaculture. They study organisms ibn the ocean or other marines areas such as brachish water.An Aquacultue farmer fams aquatic organismd. He raises fish in controlled populations and keeps them healthy. A Marine engineer designs, develops and inspects propulsion systems. they check boats to make sure the motor, pumps or other technical equipment functions properly. A fishery officer is responsible for the consecration and protection of fisheries. He carries out surveys of aquatic life, investigates fish mortalities and studies ater quality. All these people play an important role in aquaculture and together they create food for millions of
The development of the heart is a complicated process that implicates cell specification and differentiation, including tissue formation, shaping and alteration, to create a functional organ. The zebrafish has become a potential model system to disentangle the fundamental genetic, molecular, and cellular mechanisms of cardiac development and function. The liver is one of the essential organ in mammals. It performs many functions such as help the body digest food, store energy, and remove poisons. The liver also completes many regulatory functions that are critical to fetal development and to life in general. However, failure to perform theses function can result in many mammal liver diseases. Hepatomegaly is a symptom that associate with several liver disorders. Surveys had shown that a large number of the death in the US is caused by chronic liver disease. Liver cancer is another type of liver diseases that is one of the main cause of cancer-related death worldwide.
Although a freshwater tank can be full or color, it does not come close to the fiery colors that are present in a marine aquarium. Unfortunately, all the color and life that a marine aquarium holds is much more fragile and not as easy to keep as a freshwater tank. Therefore, the marine aquarium requires a plethora of devices working together and at optimum levels to maintain a successful tank. Items like protein skimmers, ultraviolet filters, sump filters, reverse osmosis units, and even wave-makers are just a few of the devices that are required to properly maintain a marine aquarium. With the exception to a properly constructed tank, nothing is as important to the marine aquarium as the water within the tank and the lighting given its inhabitants.
In man's aquarium there are many different terms for feeder fish: indentured servants, fiefs, peons, sweatshop workers, slaves. Societies have been built by these people, have sustained through the sweat of these people, and (in my opinion) might not have existed today, without the opportunity to exploit these people.
Overfishing may have some benefits to it, but does it out way the negatives? By fulfilling our demand we can wipe out our whole oceans! Not just the fish, but water mammals too. Sure it can create jobs, but as what cost? It can help bring up our economy, but at the same time it can bring it down with many fish companies closing down due to lack of profit. Fish is a great source of nutrients, but too much can kill you! In other words, fish can be both beneficial and harmful to not only humans, but everyone and everything surrounding fish. There are three things people can do to help with overfishing, the first thing is to be aware of what you are eating. Is the fish on the fear of extinction list? Also asking yourself is the fish you’re about to eat really the fish you intend to eat? Another thing to ask is, was it shipped over seas? If it was it doesn’t benefit anyone, it won’t help the economy or you. Many fish shipped from a long ways creates pollution and may have lost its nutrients value from the long voyage. One last thing to do is if you see a sewer with a sign leading to the ocean, try not to leave trash near it, or better yet don’t litter at all! All the litter left out on streets or near sewers can cause pollution in oceans, lakes, and rivers which is very harmful for marine life. You can still enjoy fish, but not at such a high demand as
...nificance that influences the everyday lives of most human beings. Commercial fishing contributes to the world economy and feeds millions of people. Feeder creatures not only provide stability for species like sharks, whales and dolphins but they also provide the commercial food fish which maintains sustainable populations.
It is believed that the world's supply of oil will last until about 2040. If you think about it, that’s not too far in the distance future. Oil is running out fast and we need to think of an alternate energy source. When we burn oil, we release carbon dioxide into the air which causes the earth’s climate to warm; a temperature rise of 3.6 degrees Fahrenheit could have serious if not devastating consequences. In the United States alone 60 percent of each person’s carbon footprint comes from the goods they buy, while the other 40 percent comes from their energy use at home, driving, and flying. That totals out to be about 10 billion tons a year. There are other energy sources but let’s think about the environmental and energy benefits of algae biofuel. Algae was first explored as a fuel alternative in 1978. Gas prices had skyrocketed, and the government was looking to help ease the crisis. The Aquatic Species Program run by the National Renewable Energy Laboratory, researched high oil-output algae for biofuel. After testing 3,000 types of algae, the program concluded that the algae, if...
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 ...
I believe that the desolation of ocean water is obsessive and should not be done. For example the water system is not consistent. Also, the water that they don't use and all of the salt goes back into the water. Lastly, with the fish screen, the eggs will go into it and die and then the repopulation will be affected. This shows that the desalination plant is an awful idea.
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
Fisheries technicians work in a variety of fish habitats, such as ponds, lakes, and hatcheries. Their focus is to protect several fish species while also maintaining their lifestyle for recreational and environmental purposes. Many of their jobs are found in environmental agencies, which include the U.S Fish and Wildlife service, recreational centers, independent research centers, Universities and other fish conversation organizations.
...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.

Growing food with Aquaponics is more efficient than growing food the traditional soil garden way. In a typical soil garden, growers end up spending hours of their time doing back breaking work on their garden, but not anymore, with Aquaponics the need for any tilling, digging, or weeding is eliminated. Aquaponics combines Aquaculture (Raising fish in tanks), and Hydroponics (Growing plants without soil). The outcome is a working system that provides plants with all the nutrients they need, while using a minimum of space, effort, water, fertilizers, and pesticides. Aquaponics allows farmers to use up to 90% less water than normal farming would use, so instead of watering your soil and having the majority of your water either lost by run off or evaporated by the sun, the water is recycled repeatedly through the system saving farmers hundreds of dollars on their monthly water bills. Also when growing with Aquaponics, much more food can be produced in a smaller space, in some cases growers have produced around twenty times the amount of produce in the same area a soil garden would. In addition, with the closed, controlled environment of the system, the need for the use of any pesticides a basically eliminated. Finally, Aquaponics enables growers to grow bigger, better and more quality produce.
According to FAO (2008), the world fisheries production by capture and aquaculture has reached 142 million metric tons which this number shows the increasing of about 26 million metric tons from the fish production in 2007. FAO reported that the scale of fish capturing has reached the maximum level and it was counted that about 77% of the fishing region in the world has now classified as fully exploited. As this scenario might cause the decreasing of new fish sources, the fishing industry will face some problems to fulfill the demand of this protein source around the world (Meryl 2007). As a result, the fisheries industry has now actively develop the aquaculture industry to make sure that the production of this protein source will meet the world demand. In contrast to the production rate in 1970 that recorded about 15.5% of fish production, the percentage is now increasing to 32.4% in 2004 and 36.93% in 2008. This show the encouraging of increasing through the year with average 7.1% per year thus show a good potential to be expanded around the world including Malaysia.
How often also does a human use or eat algae in his daily life? When most people think of algae, they probably think of something that is slimy, gross, and dirty. Algae may irritate people because it grows in unwanted places like swimming pools and boats. Algae can be toxic and it is slimy, but algae benefits people in all aspects of life. Humans obtain algin from algae to help make ice cream, pudding, face cream, and shoe polish. Algae is present in hamburgers, yoghurt, and cakes. Algae also helps make explosives, insulation, and paint. Algae produces most of the oxygen that animals breathe and without it the world would suffocate. Also, according to Helen Challand, "It is now believed that the oil and gas formed millions of years ago in the ground were created by algae" (20).
