Jump to the main text to find healthy food, but also look for the green and fun in life. Faced with global warming and climate change in time and space, how do we find out the minimum harm to the environment farming methods? 2008 World Rural Forum (WRF) to promote the "International Year of Family Farming" concept. The United Nations General Assembly in 2014, the FAO Conference (FAO) to the General Assembly the "International Year of Family Farming" issue; the General Assembly formally adopted. 2014 will be designated as the "International Year of Family Farming" "International teak Year of Family Farming". The importance of family farming needs to be attention, teak water resources utilization characteristics; maybe you can find choose another teak way of farming. We seek self-sufficiency in green living, teak but also want a way to make farming teak a minimum burden on the environment; the beauty of the earth to the next generation. The website reported organize relevant teak information for each site, are reserved and indicate sources; teak but still fear some leakage.

There are two ways to ensure that the system, the situation is sustained fish farming without interruption occurred. The first method is the use of a plurality of fish tank, and then staggered breeding. US Virgin Islands University (hereinafter referred to UVI) design Aquaponics systems are placed four fish tank. Because tilapia breeding cycle of about 24 weeks, and placed in each slot of Tilapia fish are at different stages of growth, teak so every six weeks they can be harvested again. When one of the fish tank full of fish are fish, we have to then put the new fry, then fed a total bait must be reduced by 25% to 30%, and then in the next six weeks, and then gradually fed back to the original amount of the others. This staggered teak arrangement when making breeding, feeding amount of fruits and vegetables teak and water to the degree of dependency copies will fluctuate, but the volatility is not. When the system is placed in a fish tank only when, in the fish harvest to fry fish and then put the new feeding rate will drop 90 percent, while in the next 24 weeks, and then gradually returned to the original feeding amount The feed ratio. As a result, the water supplied to the fruits of nutrients, when placed in a new fry will be reduced to very low, but at about the fish into the fish, the water rising nutrients, which will produce hydroponic cultivation system type of fruits and vegetables adverse effects. teak
Another fish farming teak to ensure teak the system is sustainable methods in a single fish tank into different sizes of fish. 24 weeks in culture can harvest tilapia, teak for example, fish tank into six groups of different sizes of fish. Then a month and then ruler into the water, remove the filter large adult fish, and then back to the same number of fry fix. Thus, to provide water to the nutrient content of fruits and vegetables do not have too much volatility. This method is applicable to a small space, and the system must reduce input costs, but it has two drawbacks. Use ruler month were nervous cause fish to fish when fishing and fish while causing only a small portion of the death. Also, avoid stunting fish salvage after too, will stay for a long time in the system's fish tank, resulting in a waste of fish feed.
Aquaponics system of fish, fruit, vegetables and bacteria need the right amount of water-soluble oxygen to achieve optimal growth. Oxygen content in water fish tank and vegetables needed to be maintained at 5 mg per liter standard. Adequate oxygen content in water, for the maintenance of those ammonia (ammonia) and nitrite teak (nitrite) toxic ingredients, into non-toxic nitrate ions (nitrate ions) of denitrifying bacteria (nitrifying bacteria) number, is also essential. Ammonia water mainly through secretion gill generated. Nitrite Aeromonas (nitrosomonas) the ammonia is converted to nitrite, and Nitrobacter (nitrobacter) then nitrite is converted to nitrate. This requires oxygen for nitrification.
In hydroponic systems, gravel, sand or perlite teak (perlite), teak are very suitable for planting vegetables media. However, in the Aquaponics system, organic particles in the water can clog the media, resulting in the flow is not smooth or deviation. When they arrived in the water can not be completely blocked organic granular media bed, the decomposition of organic particles will produce hypoxia, resulting in the death of the plant roots. Even small organic particles teak in the bed flowing teak into the implant has been filtered off, these organic particles already in the release of a lot of water, can promote the growth of bacteria and other organisms required for the water-soluble teak organic substances. Nitrification will bring the growth of bacteria. Whether dead or alive bacteria, will clog the media bed. Generally speaking, teak if it is adopted laying teak gravel or sand media bed to planting, the number and amount of fish feeding must be revised down.
King uses pipes can reduce biological fouling obstruction (biofouling) occurs. Application of the principle of gravel in the media, the same can be applied to the pipes. Aquaponics systems in high-density teak organic matter, will promote water pipes in filamentous fungi (filamentous bacteria) generation, and influence the flow. Even 4-inch diameter drain connected to the fish tank, will especially since biological fouling blocking teak reasons, resulting in reduction teak of water flow, leading to increased fish tank water. In UVI's Aquaponics system, some Tilapia can swim into drains King, the chewing attached impurities in the drain, reducing biological fouling blocking phenomenon. In addition, the lower temperature also reduces biological fouling obstruction generated.
In Aquaponics system must not use pesticides to control pests or plant diseases, because many pesticides harmful to fish, and prohibit the consumption of contaminated fish suffered pesticide. Similarly, many fish parasites or chemical treatment of the disease, but also allowed to cast Aquaponics system, teak because these drugs can harm beneficial bacteria in water, and hoarding in fruits and vegetables. Thus, biological control but the only way to inhibit bacteria and disease. Biological Control Act currently conducting a large-scale study continued, so keeping vitality robust species, such as tilapia, etc., coupled with good management is the fish parasites and most effective teak way to prevent the disease.
pH pH is considered to be an important variable, because it controls many other variables related to water quality. One of the most important variable is the nitrification. When the pH of the water pH of 7.5 or higher, the highest teak efficiency of nitrification, conversely, if the pH dropped to pH 6 or less, nitrification is stopped. Nitrification is a produce acid (acid), and the continued weakening of the role of alkaline. Therefore, pH value of pH must be measured daily, teak was added calcium hydroxide (calcium hydroxide) and potassium hydroxide (potassium hydroxide) to neutralize the acid. pH pH affects both water-soluble nutrients, while the soluble nutrients optimized pH 6.5 or pH is again slightly lower. Nitrification and soluble nutrients which must strike a balance between the two, so the Aquaponics system, pH was maintained at pH 7 is ideal. If the pH is too high pH, nutrients will precipitate and can not be dissolved in water, the plant will show the state of malnutrition, affecting crop growth and harvest. Conversely, if the pH is too low pH, ammonia, water will accumulate to an extent poisoned fish, different nutrients will precipitate and can not be dissolved in water, adversely affect plant growth and output. Therefore, it is important to monitor the pH of the water pH.
There are a senior aquaculture expert has said that aquaculture farms only need a pump can be. He said: one God, one country, one pump, and this person is the owner of California Seagreenbio aquaculture farms Dean Farrell. His farm has 100,000 Tilapia, but he only used a 13 horsepower pump. In Aquaponics system, the same reason, only to be designed and installed a pump can be. The water hit the highest point from the lowest point in the system, each point are close to each other side by side, and then let the water flow through the action of gravity, flow into the system every corner. teak Law of a pump can save money and bring success.
