Introduction to Aquaponics system

Research and Development needs The current and escalating extent of Environmental pollution, soil degradation, water scarcity and climate-related challenges plaguing safety food productivity in every corner of the world and particularly in the resource-scarce regions demands for a re- evaluation of the way we produce the foods that keep us alive and seems to beg for what could be referred to as another green revolution.

Research and development needs The need for the development of innovative, resource efficient and locally appropriate food production system solutions is immense and this need is greatest in high densely populated and resource-poor nations. N ew P roduction S ystem S afety food

What is Aquaponics? Aquaponics systems form in the process of rearing occurs within a variety of organic compounds absorbed by the plants through the process of denitrification bacteria of rearing filtered again, and through this process to take advantage of the fish farming aquaculture and hydroponic fused organic food production methods. Aquaculture Hydroponic Aquaponics

Environmental Friendly Systems What is applied aquaculture technology? Closed recirculating aquaculture system Environmental Independent Systems Environmental Friendly Systems Economic Energy Systems Operating independently without being affected by changes in the external environment. Environmental management of the environmental control of rearing systems utilizing stable rearing. Environmentally friendly form recirculating systems minimize pollutant. Energy-saving form, breeding system(recirculation). Advantage Weakness The initial investment in facilities costs a lot. There are many maintenance costs. Operating and management expertise is required. (Kim Byeong Gi, 2011) Filter Fish Tank

Environmental Friendly Systems What is applied agriculture technology? Hydroponic system Advantage No soil is needed for hydroponics. The water stays in the system and can be reused - thus, lower water costs. It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs. No nutrition pollution is released into the environment because of the controlled system. Pests and diseases are easier to get rid of than in soil because of the container's mobility. Stable and high yields. It is easier to harvest / No pesticide damage / Plants grow healthier : It is better for consumption Hydroponics may potentially produce much higher crop yields. Hydroponics can be used in places where in-ground agriculture or gardening are not possible. Weakness Without soil as a buffer, any failure to the hydroponic system leads to rapid plant death. Many hydroponic plants require different fertilizers and containment systems. The propagation of the pathogen is spread quickly and in a short time a large amount of Little useful microorganisms in the nutrient solution, there is very little cushioning effect.

Environmental Friendly Systems The aquaponics system development objectives Inland farms aquaponics system problems and environmental pollution load hydroponic nutrient solution supply and processing problems. Advantage Weakness Aquaponics system

Environmental Friendly Systems The closure device within the rearing water flows rapidly changing environmental conditions such as temperature changes and are not affected. The normal purifying rearing water is able to grant the environmental conditions suitable for the growth of organisms form. The form of the growth period is shortened or the rearing efficiency can be increased to help increase the economic value added. Reduce the amount of effluent. Are available year-round continuous-density production of safe food. Advantage Weakness The aquaponics system development objectives The system structure is complex. The technology development is lacking.

The current of the world aquaponics development

* Since The current aquaponics system has been studied mainly in the agricultural sector. The purpose of water retention, and to reduce pollution of lakes, rivers, and groundwater caused by chemical fertilizers. (Retrieval Site) 1. Aquatic Science Collection( 2. KISS( 3. Web of Sciences(

Combination of trout and lettuce start in the 90s. Currently, the using a heating breeding, lettuce and fish such as tilapia and catfish are produced in large quantities. Taking profits by selling the produce of tourists in the Caribbean to develop a national policy aquaponics system since 2009, and has been operating in the form of cooperatives. The aquaponics system since 2004, starting with the concept of private farms, and aqua phonics to operate the system in each region between farm organic networking and technology development is done. About the the complex farming methods of hydroponic vegetable breeding using the form from the Ministry of Agriculture and Forestry, in the late 90s, was stopped after continuous research, research in progress, but did not lead to industrialization. The corporatization 1985 was done. Most companies have their production systems and related devices, products and systems are sold, local schools and education programs are linked

Environmental Friendly Systems Nutrient Cycling in aquaponics system Nutrient Nutrient Cycling - Denitrification N, P, K, Ca, Mg, S, Cl, Fe, Mn, Cu, Zn, B, Mo All the nutrients needed for hydroponics vegetables, fish breeding. At using fishmeal, including bones and minerals formulated diets containing 2% to 3% Is the most critical of the bacteria to breed in the aqua phonics system (nitrifying bacteria Nitrifying bacteria). Increases the effect to purify the breeding aquaponics in the system continuously transforming ammonia to nitrite, bacteria, they cause changes to nitrite to nitrate, nitrite bacteria nitrification plant by absorbing the products of this process.

The development of Eco food production by aquaponics system

The actual development of the aquaponics system. An experiment was conducted for compare hydroponic and general aquaculture with Aquaponics for 4 weeks to investigate on the change of rearing water's nutrient quality on leaf lettuce (Lactuca sativa L.)production, nutrient uptake and growth at the Chonnam national University, Korea. 3 stage[1 stage : fish tank(150L), 2∙3 stage : Plant grow bed(1 ㎡ )] 24-hour circulation pump using unfiltered water system LED lamp(red:blue=2:1) and fluorescent light(T5, 6400k) used for 06:00 to 20:00(14h/day) Grow media  Hydroton(3~5mm) Auto siphon system How to experiment aquaponics system
