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.
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
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.
Aquaponics systems are the combination of aquaculture (raising fish in a tank) and hydroponics (growing of plants in a soil-less environment) that facilitates the growth of the fish and plants simultaneously in one integrated system. The waste produced by the fish would provide a source of nutrition for the growing plants and the plants naturally filter the water in which the fish live in. Another process involved in the aquaponics system is the participation of microbes (nitrifying bacteria) and composting red worms that flourish in the growing media. They convert the ammonia present in the fish waste into nitrites, then into nitrates and the solids into vermicompost that serves are food for the plants. By combining both aquaculture and hydroponics, aquaponics capitalizes on the benefits of both and eliminates the downsides associated with them.
This is known by the many fishing laws and policies that have been created for fishermen to obey in everyday life. Most are considered to be known without seeing the laws because it is basic morals and principals everyone should know. The most important one to the topic at hand is the right to fish comes with certain obligations and responsibilities to help ensure conservation of aquatic and costal resources and those affected (Lam 309, FAO.Code). This basically says when fishing, the fishermen has to take responsibilities for their actions. To conserve the lives of many aquatic animals, all rules must be followed accurately. If not it’s a risk to almost all the populations of aquatic species because it causes a chain reaction. If the food supply is damaged, the species dies, and that same species that dies could have also been a food source to another species that in turns dies as
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
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.
Overfishing is a growing world problem. In 2013, 93 million tonnes of fish were caught
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 ...
Fishing and harvesting of seafood have been a part of our society, and over the last few decades, it has skyrocketed in sales throughout the United States. In fact, in 2006 there were about 30 million people in the United States alone that engaged in recreational fishing. Seafood harvesting includes locally caught, imported, aquaculture knew more commonly as farm raised. In 2013, the amount of fish and shellfish harvested from the wild was about eight times greater than the amount of seafood produced by the domestic aquaculture farms.
Overfishing doesn’t only occur in the U.S, but we are the only country that makes regulations for the amount of fish we can keep. Other countries do not make regulations which makes overfishing even worse and it is ruining the solutions we are trying to make. "Overfishing and pollution also threaten coral in Madagascar. But climate change -- and the warming and ocean acidification that come with it -- is expected to land the soundest blow." (CNN, Sutter) This reveals that overfishing happens all over the world and it affects many people. If the fish are being overfished, than it will affect the human food
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.
Fishermans fish before new fish can be born to replace the ones that were caught. Its takes some fish a month or more to reproduce. Thats why we have a calendar for seasons to catch the fishes and it helps the fish to reproduce. Overfishing, typically, leads to a decline in the population of productive fish, which results in lesser stocking of the fish. If overfishing is curtailed, we can hope to revive the declining marine population in a few years.
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
