Ariel Parker Dr. Habte Churnet Assignment #1/ Oceanography February 5, 2008 Oceanic Productivity Humans are on the top level of the food chain, with the lowest being the primary producers. The average ocean productivity is about 50 grams carbon per square meter per year. The productivity of the open ocean is comparable to desert production. In ten years the market for wild Alaskan salmon has been replaced by farm raised Atlantic salmon. One reason is that Pacific Salmon is in season only one month a year. The other eleven months, wild salmon is only available frozen or in a can. Salmon is low in calories and saturated fat, yet high in protein, and a unique type of health-promoting fat, the omega-3 essential fatty acids. In addition to being an excellent source of selenium, a very good source of protein, niacin and vitamin b12, and a good source of phosphorus, magnesium, and vitamin B6. Salmon also guard against heart disease and keep the mind agile. It is also suggested that salmon slows down Alzheimer’s disease.
