Jason King 1-23-13 - Informative Outline 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. (Transition: Let’s begin with the global need for a secondary source for seafood and the reasons behind sea farming.) II. 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. 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. The United Nations and many global organizations have effectively limited the amount of offshore catching allowed annually. 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. World aquaculture production attained another all-time high in 2010, at 60 million tons, with an estimated total value of US$119 billion.
Attention Step: My father took me fishing to a fish farm when I was a child giving me my first glimpse into aquaculture. 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. 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%. Preview: The three topics being covered today will be the reasons behind sea farming, the current projects, and future possibilities of sea farming.
Water sources can be classified into several categories some of which are wells, springs, groundwater, streams, rivers and lakes.

Today, fish provides more than one billion poor people with most of their daily animal protein.Fish provides nutrients and micronutrients that are essential to cognitive and physical development, especially in children, and are an important part of a healthy diet.Aquaculture Aquaculture is a form of agriculture that involves the propagation, cultivation and marketing of aquatic organisms in an controlled environment.The history of aquaculture first begun in ancient China some 4000 years ago with ornamental carp ponds to today's 4 million commercial production of catfish in the southern states of America.While sustainable fisheries management is a challenge, solid global and regional governance of these vital resources will ensure that we can produce enough fish for those living in poor regions.Aquaculture, in particular, has tremendous potential to enhance food security and be environmentally sustainable.As an affordable animal source of protein in some of the poorest countries, fish is the primary source of nutrition, creating growing demand for this staple.However, fish supplies are failing to meet demand and there are major shortages in some critically poor countries where they are needed most.Globally, more than 250 million people depend directly on fisheries and aquaculture for their livelihoods and millions are employed in fisheries and aquaculture value chains in roles such as processing or marketing.The very poor often rely on fishing as a primary source of income.
