What is it?

Aquaculture is the cultivation of natural produce of water such as fish or shellfish, algae and other aquatic organisms.There are over 200 species of organisms that are cultured such as many different species of fish with talapia being the most common, pearls, frogs, shrimp,and many more.

How does it work?

The main process behind aquaculture is first the organism is chosen for cultivating. They can be grown in a wide variety of natural waters and atrificial systems. Thay can also be raised in raceways, tanks, pools, and cages constructed of plastic, metal, concrete, wood, glass, or any other materials that will hold water and are not toxic to fish. After they are placed in their selected enviornment.The organisms are farmed or produced. Once they are done growing they can be sold to markets, they can be stocked in recreational ponds and free-fishing waters, they can be used for bait, and some aquatic animals can be sold as pets.

Applications of Aquaculture

With the incresased demand for fish, seafood and other things that can be grown in a controlled enviornment, aquaculture can help to fill that demand with mass production of these things. In 2000, 45,700,000 pounds of total products from aquaculture were produced bringing in a total of 56,500,000,000 dollars. A lot of of the seafood we see in the markets come from aquaculture. 27.3 percent of all our seafood comes from aquaculture. Also, over 200 species are cultured with aquaculture.

What is it?

The controlled cultivation and harvest of aquatic plants or animals(edible marine algae, clams, oysters, and salmon).

How does it work?

Fishermen hunt for edible fish that they then send to factories to be cooked and or frozen to be shipped off to restaurants, super markets, fish markets, and other places or small businesses that sell fish.

What does it do?

You are able to feed fish less quality of food to get a higher protein because they are cold blooded and they dont have to use that food energy to keep themselves warm. For example, a catfish may take in 6kg of feed and produce 1kg of meat, but a chicken may take 10kg of feed and a pig might take 30kg of feed and both of them will only produce 1 pound of meat.

What is aquaculture?

Aquaculture is the science, art, and business of cultivating marine or freshwater food, fish, or shellfish, such as oysters, clams, salmon, and trout, under certain conditions.

How does it work?

Scientists breed fish and other underwater animal life in a controled enviorment. The water is designed to fit the needs of underwater life being breed.

Capture Gounds

Obtain the sperm and eggs of the fish. Fish are not harmed.

The Fish Pond

The fish move into a tank, until they mature. After Maturing, the fish are moved into ponds. Ponds give them a natural home.

The Releasing and Tagging

Fish get transferred to transporting tanks. The fish are then tagged and numbered. Finally the fish are released into the wild.

What does it do?

The application of aquaculture are the fish farming, oyster farming and even hydroponics. When dealing with hydroponics, fish are breeding in the same water that the plants are being grown and the fish's manure adds nutrients to the plants. Hydroponics is the growing of plants underwater without using soil.

Stabilizes the ecosystem and the wild life in the waters.

Allows fishing industries to keep their business running while not endangering the species.

What is it?

Farming of plants or animals in fresh or marine waters. It is the aquatic equivalent of agriculture and often referred to as the "fish farming."

Aquaculture-Science, art, business, and cultivating of marine or fresh-water food fish or shellfish, such as oysters, clams, salmon, and trout under controlled conditions.

How does it work?

Farm systems are used to hold in fish and other marine animals. These farm systems are split up into big sections and then with proper feeding and proper maintaining of the environment then all the animals will survive. After large amounts of the species are produced they are retrieved and sold on the market.

What are the environmental issues?

Aquaculture may reduce depletion of fisheries and protect endangered species. Scientists are investigating genes that will increase production of natural fish growth factors as well as the natural defense compounds marine organisms use to fight microbial infections. Increased public demand for seafood and dwindling natural marine habitats have encouraged scientists to study ways that biotechnology can increase the production of marine food products. Making aquaculture the growth of aquatic organisms in a controlled environment, a growing field of animal research.

Aquaculture

By: Tyree N. and Casey C.

 

What is it?

Aquaculture is the farming of various types of fish. This includes tilapia, trout, shrimp, salmon, freshwater prawn, mollusks, and oysters. The fish are genetically engineered and produce more fish.

 

How does it work?

The fish are grown indoors or outdoors in labs, sometimes using recirculated water and they are grown in many different environments.

 

What does it do?

Farming fish grows cleaner, fresher fish that are always in season. It fulfills the demand for seafood, and replenishes the fish that are lost by pollution and overfishing. It also is cheaper for the consumers, and makes the consumers happy because they have better fish.
