Topic: Sea Farming
General Purpose: To Inform
Specific Purpose: To inform the class of the need for sea farming, current projects, and future possibilities of sea farming.

I. Introduction A. Attention Step: My father took me fishing to a fish farm when I was a child giving me my first glimpse into aquaculture. B. Thesis: Sea Today I am going to introduce everyone to the world of sea farming, or Aquaculture production of seafood, which is and will remain the most rapidly increasing food production system for many years to come. C. Significance: According to The 2012 state of world fisheries and aquaculture, released by the Food and Agriculture Organization of the United Nations(FAO),, fish provides about 3.0 billion people with almost 20% of their intake of animal protein, and 4.3 Billion with 15%. D. Preview: The three topics being covered today will be the reasons behind sea farming, the current projects, and future possibilities of sea farming.
(Transition: Let’s begin with the global need for a secondary source for seafood and the reasons behind sea farming.) II. Main Point: A. According to Scientific American, June 17, 2007, between 1950 and today the total landed catch from open- and inland-sea fishing almost quintupled, from around 20 million to about 95 million metric tons. 1. This trend has lead to severe overfishing of the ocean and over 70% of the world’s fish species are either fully exploited or depleted. B. The United Nations and many global organizations have effectively limited the amount of offshore catching allowed annually. C. Also found in The 2012 state of world fisheries and aquaculture, released by the Food and Agriculture Organization of the United Nations(FAO), the last three decades (1980–2010), world food fish production of aquaculture has expanded by almost 12 times, at an average annual rate of 8.8 percent. 1. World aquaculture production attained another all-time high in 2010, at 60 million tons, with an estimated total value of US$119 billion.
(Transition: Now that we fully understand the need for alternative sources, let’s examine what is currently happening in the world of Sea Farming.) III. Main Point: A. A popular style of cage around the US is also used at the University of New Hampshire, and off the coasts of Hawaii. B. A news release on on September 2007 details the 4 UFO shaped cages grouped together and anchored to the seabed with 25k pounds of weigh and several cables. 1. These cages also have an 80 ton buoy that holds up to 20 tons of food which will support 15,000 fish by remote. C. Some locations are finding that the current isn’t sufficient to carry the waste far enough or fast enough causing algal blooms/red tides that will turn around and kill the stock. D. An MIT newsletter released September 2008 describes test they are running on self-propelled cage for fish farming enabling them move to other locations. 1. The propellers powering these cages will be powered by a diesel generator mounted on the buoy alongside the feeder.
(transition: Now that you have a good idea what is going on today, I’d…
