Ann M. Coulston and Carol J. Boushey See book keywords and concepts | With fish farming, levels of cholecalciferol in fish raised in aquaculture cannot be assumed to be equivalent to those in wild species. Further, it is now recognized that levels in fish are much more variable than previously recognized [35]; therefore, caution must be taken in using data from Table 2. Other concerns about consumption of fish or fish oils include consumption of too much mercury and vitamin A. Land animals that are exposed to sunlight or have vitamin D in their feed may be a source of vitamin D, but the amount of vitamin D provided as meat is not well documented except for liver. | David W. Grotto, RD, LDN See book keywords and concepts | Salmon aquaculture is the major economic contributor to the world production of farmed finfish, representing over $1 billion in the United States annually.
Where Do Salmon Come From?
Salmon live in the Atlantic and Pacific Oceans, the Great Lakes, and other lakes throughout the world. The Kamchatka Peninsula in eastern Russia contains the world's greatest salmon sanctuary. The majority of Atlantic salmon in today's market is typically farmed (ninety-nine percent), while the majority of Pacific salmon is caught in the wild (eighty percent). | Alex Steffen See book keywords and concepts | Shellfish aquaculture can actually have a positive impact on the environment. Creatures such as oysters, clams, and mussels eat by filtering plankton from the water, needing no external food supplements. Since their harvests must come from clean waters, shellfish farmers often make staunch advocates for coastal ecological preservation. Much of the shellfish on the U.S. market today is farmed.
Fin fish farming in coastal waters can be more problematic. Farmed salmon, raised by the thousands in net pens, produce a corresponding load of water-polluting feces. | | How about improved water-use efficiency; reduced pesticide use; agroforestry (both to maintain nearby forest resources and to improve carbon sequestration); conservation tillage; even aquaculture (to incorporate fish and seafood as part of a larger integrated farm system)? All wonderful ideas, but of course the reason that industrial agriculture remains dominant is that it's so much more productive, right? Wrong. | | Farming fish and seafood through aquaculture has taken off, but fish feedlots generally take their cue from cattle feedlots—they are over-crowded, soaked in chemicals, and polluting.
Plans are being implemented to recover fisheries in many parts of the world. Scientists and fish advocates are calling for the establishment of protected marine reserves, international conservation agreements, and quotas. Simultaneously, businesses are springing up based on principles of better and more sustainable seafood farming and harvesting practices. | | Ultimately, a growing market for such seafood will drive fishing and aquaculture practices—meaning that our dollar does carry real power for change. eg & gf
Sustainable Fisheries Certification mmmm Unlike the Department of Agriculture's Organic Standard label or the Environmental Protection Agency's Energy Star label [see Using Energy Efficiently, p. 166], a standard, overarching sustainable fisheries' certification has not yet been established for restaurants, retailers, and fishers. | by Michael Murray, N.D. and Joseph Pizzorno, N.D. See book keywords and concepts | | In 2004, total worldwide seafood production (excluding aquatic plants) was estimated to be nearly 150 million tons, of which 58 million tons came from aquaculture. China was the leading seafood-producing country with 16.5 million tons, followed by Peru (8 million tons), the United States (6 million tons), Japan (5 million tons), and Indonesia (5 million tons).

The status quo doesn't want you to read NewsTarget
Sadly, the vast majority of news consumers would rather live in their imaginary world of distorted information.
Admittedly, it's easier to do so. Seeing the events of the world for what they really are takes courage, skepticism and a willingness to challenge and reform your own ingrained beliefs. | Alex Steffen See book keywords and concepts | The Future of aquaculture mmmm Dr. Martin P. Schreibman has been growing tilapia for years in tanks in his lab at the Aquatic Research and Environmental Assessment Center of Brooklyn College. "You could set a tank up in your basement and grow enough fish to pay your rent," Dr. Schreibman stated in a New York Times article, and it may be true. He envisions a day when fish farming throughout New York City—using systems scalable to tight urban spaces—will replace resource-wasting importing as a ready source of local seafood. | John Croft See book keywords and concepts | The combination of the environmental and commercial benefits of marine farming (sometimes referred to as mariculture or aquaculture) can provide this support. This has to be a progressive step toward maintaining what is, after all, the lifeblood of our planet Earth in a survivable condition.
The reader will notice that extracts from the same animals or plants appear in the list of treatments for a variety of different diseases. This is because there are common symptoms to a range of diseases, and the treatment of these symptoms is an important part of the overall management of the disease. | Mike Adams, the Health Ranger See article keywords and concepts | We actually started producing natural astaxanthin as a replacement for synthetic astaxanthin that's currently used in fish farming, and we do continue to sell into the aquaculture industry. But as our production started ramping up, we became aware of the very potent antioxidant properties of natural astaxanthin, and as we did more research and started looking more at the scientific literature, we found that natural astaxanthin has three very unique properties: first of all, it's an extremely potent antioxidant. Some studies have shown over 500 times stronger than vitamin E. | Brian O'Leary See book keywords and concepts | The human desertification of the Earth, the declining quality and availability of water, and the preservation of global aquaculture are each in themselves major issues to be urgently investigated as public policy, to be addressed by a global green democracy described in the next chapter.
The Quality of Water
Even though we're familiar with its chemistry and many of its unique properties, water is magic stuff . All life as we know it depends upon liquid water to survive. We are made mostly of water. We need it to drink. Water covers two-thirds of the Earth. | John Robbins See book keywords and concepts | In 1985, barely 5 percent of the world's fish for food was produced by aquaculture. But by 2000, the share produced by fish farms accounted for nearly a third of the world's total fish consumption.4 By then, virtually all the catfish and rainbow trout, half the shrimp, and one-third the salmon eaten in the United States were the product of fish farms.
Unfortunately, the promise of aquaculture to alleviate pressure on marine ecosystems has thus far proven disappointing. | | But there is yet one more parallel between aquaculture and factory farms—enormous waste problems. The caged salmon grown in Scotland, for example, contaminate Scottish coastal waters with an amount of untreated waste equivalent to that produced by 8 million people.85 Yet the entire human population of Scotland is itself barely more than 5 million.
And it's not just salmon. In the last few decades, the growth of high-intensity manmade shrimp farms has been staggering. | Michael F. Jacobson, Ph.D., Lisa Y. Lefferts and Anne Witte Garland See book keywords and concepts | | The types of seafood being produced by aquaculture include catfish, salmon, trout, redfish, sturgeon, hybrid striped bass, carp, tilapia, oysters, and crawfish. Although fish farming conceivably could help avoid chemical contaminants, it can cause problems of its own:
>• In fish farms, it isn't unusual for a large number of fish to be reared in a small, confined space, which may result in stress-related disease—and the use of drugs to control it. According to the FDA, little is known about the resulting drug residues in fish. | | The FDA says that while many of the drugs used in fish farming have been in use for years and may be legal for use in other animal species, most haven't been approved for use in aquaculture and don't have established "withdrawal" times to allow the drugs to pass out of the fish before they are sold.11 In 1988, Argent Chemical Laboratories was found guilty of illegally distributing drugs and pesticides for use by fish farms and fined $70,000. | | Farm-raised fish may have lower levels of the heart-protecting omega-3 fatty acids than are found in wild fish, because of the type of feed used in aquaculture.14
Industrial chemicals. The single biggest chemical risk in seafood comes from PCBs, which are carcinogenic and can impair the healthy development of fetuses. In 1984, researchers at Wayne State University and other universities examined infants of women who reported regularly eating an average of two or three meals per week of PCB-contaminated fish from Lake Michigan. | | Most commercially harvested catfish is farm-raised, and relatively uncontaminated with pesticides, but drug residues from aquaculture might be a problem.
/ Despite their high fat content, salmon (except those caught from the Great Lakes) tend to be relatively free of chemical contaminants.
ž Don't buy ready-to-eat seafood that's displayed right next to raw seafood, since it can be contaminated with bacteria from the raw seafood.
IN YOUR KITCHEN
ž Handle and store raw seafood carefully so that it doesn't come into contact with cooked food. | | The program should include better control and cleanup of water pollution; adequate inspection and testing of fish for natural toxins and microbiological and chemical contaminants; protection for whistleblowers; and controls on aquaculture. | John Robbins See book keywords and concepts | Edwin Rhodes, aquaculture coordinator of the National Marine Fisheries Service, says, "We have to have absolute certainty that transgenic fish do not interact with wild stocks."11
But the enclosures in which farmed salmon are usually kept are net pens, and they are notorious for being torn by waves or by hungry wild fish.
How often do farmed salmon escape? Routinely, sometimes by the tens of thousands. Almost 1 million farmed salmon escape annually in Norway alone. | Ralph W. Moss, Ph.D. See book keywords and concepts | Some sources of mail order fish are aquaculture Marketing Service, 356 W.

Linseed Oil: Many people give more thought to their motor oil than their eating and cooking oil. While most food oils do contain some linoleic acid, few contain the important linolenic acid, as well. For example, safflower oil is a good source of linoleic acid, but it has little or no linolenic acid. | John Robbins See book keywords and concepts | In 2000, Rosamond Naylor, a senior research scholar at Stanford's Institute for International Studies, wrote in a cover story in the journal Nature that "aquaculture is ... a contributing factor to the collapse of fisheries stocks around the world.'"f
She and the articles' other authors, representing institutes of aqua-culture from all over the world, added that as a result of fish farming, some populations of herring, mackerel, sardines, and other fish low in the marine food chain are in danger of disappearing from the world's oceans. | Sheldon Saul Hendler and David Rorvik See book keywords and concepts | Effects of food containing betaine/amino acid additive on the osmotic adaptation of young Atlantic salmon, Salmo Salar L. aquaculture. 1989; 83:109-122.

If you can't be a vegetarian, eat a vegetarian shrimp. In studies where individuals are fed shrimp, a rise in blood cholesterol levels is not observed, since most cholesterol is made in the body by the liver rather than taken in from the diet.
