7. Water Bear (Microscopy)
   "Strangely enough, water bears are at the same time among the most unknown and the most fascinating creatures on earth. They have successfully escaped man's exploitation of nature and still can be found almost everywhere on earth. Scientists have reported their existence in hot springs, on top of the Himalayas, under 5 m layers of solid ice and in ocean sediments. Many species can be found in a milder environment like lakes, ponds and meadows, others prefer stone walls and roofs. But their most typical homes are moss cushions." 7-05

8. -Freshwater: How Much Do We Have? (National Geographic)
   "f you had a dollar for all the water in the world, less than half a penny would represent the world's supply of fresh water in rivers, lakes, and wetlands, which includes ponds, marshes, swamps, and bogs. That halfpenny—0.3 percent, to be exact—represents the Earth's surface water, which we draw upon every day to quench our thirst, water our crops, and power our industries." 06-07

9. Sustainable Aquculture Development (FOA.org)
   "In traditional, extensive aquaculture, fish can be bred in open waters such as lakes, estuaries or coastal bays, where they feed on naturally available nutrients, or in farm ponds, where they can be fed with by-products from the farm. Traditionally in China, more than five species of carp are bred together to make the best use of feeds and ponds." 08-07

10. Pond Culture (Fishing and Aquaculture - Australia)
    "Pond aquaculture is the use of purpose-built earthen ponds, generally with water supply and drainage infrastructure incorporated, to grow fish and crustaceans.

11. Pond Construction (TheRealMcKoi.co.uk)
    "It is very important to know how many gallons your pond contains, as this is vital information when you are required to treat your pond, in order to keep your pond and fish in tip top condition." 08-07

12. Pond Fish (TheRealMcKoi.co.uk)
    "Before any fish or plants are added to your pond you should switch on your pump and circulate water for several days.This allows time for the Chlorine & Chloramine (which is harmful to both FISH AND PLANTS) to be safely removed from the tap water." 08-07

13. Pond Plants (TheRealMcKoi.co.uk)
    "Submerged oxygenating plants should be considered essential in most ponds as they absorb many chemicals from the water, such as metallic salts. As ordinary tap water contains such substances it is a good idea to have several bunches in your pond. This will go a long way towards taking the hard edge from tap water." 08-07

14. Pond Filters and Pumps (TheRealMcKoi.co.uk)
    "Although it is not compulsory to install a filtration system,I would recommend you do, as it can make a substantial difference. Not only to the clarity of the water, but more importantly, it helps to purify the water by eliminating toxic waste products such as ammonia and nitrites, both having a detrimental effect on fish, which could lead to diseases and ultimately death." 08-07

22. Controlling Pond Algae
    "The war on green water is a battle that can be won. Even though the nutrient source cannot be eliminated completely, it can be limited to a workable size. With plenty of plant life, a good U.V. Sterilizer, and appropriately sized filtration, crystal-clear pond water can become a reality. There are even some good products to help you along the way, if you know what to look for." 11-08

24. Duckweed for Wastewater (BiomassMaagazine.com)
    "Due to its high affinity for absorbing pollutants in wastewater, Stomp posed a hypothetical scenario where the use of duckweed by farmers could mutually benefit a city willing to provide wastewater effluent for fresh water reuse. For example, a farmer could pay the city or municipality for its wastewater and have it transported to his farm, a concept that some people refer to as duckweed-based wastewater treatment, Stomp says. The farmer could take that wastewater and mix it with his livestock wastewater to dilute it so that it can be used to grow duckweed, which would clean the water and the farmer could sell it back to the municipality for reuse."
    
    "Duckweed can also reduce algae growth (by shading), coliform bacteria counts and mosquito larvae on ponds, while concentrating heavy metals, capturing or degrading toxic chemicals and encouraging the growth of other aquatic animals such as frogs or fowl. Additionally, duckweed is one of the fastest growing plant species on the planet. Scientists are also beginning to unlock duckweed’s potential as a player in carbon cycling and carbon sequestration." 06-09

25. Pond Maintenance (Awesome Library)
    "You don't need to be a biologist or chemist to keep your pond water clean and healthy. While undoubtedly having that sort of background helps to understand all of the processes that take place in a pond, a simple crash course in pond water chemistry can go a long way to helping the average pond owner become more knowledgeable and have a successful pond maintenance program." 03-07

26. Pond Maintenance
    "Ponds and lakes such as those seen on farms, golf courses or on commercial grounds often encounter water quality issues in the form of cloudiness, murkiness and even odor as a result of organic waste present in the pond. This organic waste comes in many forms like leaves, grass clippings, animal waste, excess fish food and even fertilizers, which all contribute to problem causing nutrients."

30. Ultraviolet Light for Algae Control
    "Even though aquariums require artificial lighting to imitate daylight for the fish, you do not require any type of artificial lights for fish ponds. However ultraviolet lights are primarily used to sterilize as well as filter pond water. This type of technology is also utilized in various industries, by doctors to get sterile water and by campers as well as armed forces for sterilizing their drinking water. Ultraviolet lights for ponds burn out the algae."
    
    Warning: Strong ultraviolet light can damage your eyes if you look into it; avoid looking at ultraviolet light. 11-08
