Transcript of Fish Farming

Presentation by: Mary G, Celsea E, and Nika G. Fish Farming: Aquatic Biotechnology What is Aquatic Biotechnology? Summary Increasing the world's food supply
Restoring and protecting marine ecosystems
Identifying novel compounds for the benefit of human health and medical treatments
Improving the quality and safety of seafood
Increasing knowledge of biological and geochemical processes in the world's oceans
(Possibilities of utilizing aquatic organisms) What can Fish Farming and Aquaculture do for us? Fish Farming is used for more than just human consumption: organisms are raised to provide bait fish, harvested to make fishmeal and oils used to feed cattle, swine, poultry, growing pearls, culturing species to isolate pharmaceutical agents, breeding ornamental fish (goldfish and tropical aquarium fish), and to stock recreational areas.
Aquaculture various widely to due the needs of certain fish, so the process may differ; yet breeders all look for certain desirable characteristics in their fish, such as: muscular features, growth rate, health, quality, and color.
Fish Farming Specifics Barriers and Limitations:
The complications: barriers, limitations, and harmful effects Aquaculture has many different benefits, not just fish farming!
Fish farming helps the environment, increases food production, and is beneficial to the economy.
Fish farming varies based on the type of fish.
There are some problems to keep in mind.

Work Cited Aquatic Biotechnology: The use of aquatic organisms such as finfish, shellfish, marine bacteria, and aquatic plants for biotechnology appilcations. Aquaculture: Farming finfish, shellfish, or plants for commercial or recreational uses. The fish farming industry can aid in increasing the world's food supply. In fact, with the global population expected to increase by 3 billion people in 2050, the demand for aquaculture is going to grow by about 70% in the next 30 years! (recent estimates suggest that 50% of all fish that humans consume worldwide are produced by aquaculture and fish farming techniques)
Aquaculture is a current solution to the problems of overharvesting, loss of habitat, and depressed commercial fishing.
Aquatic biotechnology is quite an economy friendly industry; in the U.S. alone, aquaculture grosses about 1 billion a year (and that is only 5% of the world's seafood)
In theory, the ability to farm fish, and farm them quickly, should lead to lower retail costs for consumers. Yes, breeders can change the color of the fish depending on what the consumer market wants to see! Astaxanthin, sometimes called "salmofan", is like the home depot paint section for farmers when choosing a color for their salmon. Not all species, some of the most prized species, are suitable for fish farming as they require large amounts of space to roam.
Water quality; proper flow to mimic natural environment, removal of waste, adequate amount of nutrients.
Aquaculture works best for fish with uncomplicated life spans (or life spans that are well understand by fish farmers).
Controlling spread of disease for large groups of fish.
Cost effective: is fish farming worth it?
Strict Rules and regulations. Is there really harm in farming fish?
It actually takes wild caught fish to farm fish; on average, growing 1 pound of salmon can require 3 to 5 pounds of wild caught fish.
Runoff from the fish feces can be harmful to other animals and humans.
Some farmers resort to killing birds, "pests" that feed on their fish.
Farmed fish can escape into the environment and compete with wild fish, causing harm to the species. Thieman, William J., Palladino, Michael A. Introduction to Biotechnology. Third Edition. New York: Pearson, 2009. Print. Video curtsey of Science channel program: How it's made
