**Rice Fish Farming in China vs. Ocean Trolling In Oregon**   Rice fish farming system is mainly used and practiced by the Asian countries, such as China, Philippines, Indonesia, and Japan. It is widely adapted in countries where traditional rice farming methods have been practiced and used for centuries. In this farming technique, fish stocks that are raisedin the field are not managed, which allows more variety of wildfishes to enter the paddy during flooding season (adding more population to the original fish stocks). It is an ancient Chinese farming practice which can be traced back to two centruies ago.  Ocean trolling practiced throughout the world. It is a hook and line fishing where several lures or baits are lowered into the water and pulled slowly behind the boat as the boat sails. When salon are attracted to the gear and strike while feeding on natural bait in the area, the fisherman then lands each salmon individually and cleans it immediately to pack it in ice for delivery (Oregon Salomn Commission).

Output: fish, pollution from land run off, less fertile soil, relatively fresh food quality, limited amount of fish stock (sometimes, there will be some other species coming into the water during the flooding season) system characteristic: selective breeding, artificial breeding (but also very nature), mixed farming || Input:oil (to generate the fishing boats), oxygen, human resources Output: water pollution, fish stock,food product (frozen fish stock), delicious fish meat (food quality), large amount of fish stock (food quantity) system characteristic: if not overfish, then sustainable, free style fishing ||
 * System Components:**
 * Rice farming || trolling ||
 * Input: artificial feeding, small fishes (fish eggs), water, land, oxygen, human resources


 * Environmental Impacts:**

● may lower groundwater levels noticeably in some coastal areas ● not able to conserve soil fertility ● increase the risk for the agrochemicals( pesticides) to be washes off from the land to the water, where fish are raised, and by the process of bioaccumulation, the toxic that stored inside the fish will harm people who consume it ● Increase the amount of agrochemicals will also create pollution to neighbor lands and water ● “Chronic toxicity is a long term effect that could be related to changes in disappetite, growth, metabolism, and reproduction and even death or mutations” Positive: ● growing rice and fish together in one place can lead to a more abundant ecosystem environment since more species/ vegetations are able to live there ● conservation of water resources and plant nutrients (Bibha kumara, Integrated Fish Farming) ● intensive production of fish protein (Bibha kumara, Integrated Fish Farming) ● reduced operating costs relative to either system in isolation. (Bibha kumara, Integrated Fish Farming) ● water can be reused through the process of filtration and recirculation, less water wasted (Bibha kumara , Integrated Fish Farming) ● the excess rice can be used to feed the fish in the water, thus " the waste products of one biological system serve as nutrients for a second biological system" (Bibha kumara, Integrated Fish Farming)

 * <span style="font-family: 'Times New Roman',Times,serif;">In Sichuan and Guizhou Province (south and southwest China), rice is the most important crop for Chinese to consume. In almost every meal, Chinese eat rice with other dishes. Eating rice has become a part of their life and rice faming was very common. Therefore, rice farming of carps also became very popular. Chinese farmers began to plot rice seeds along with fish eggs into the field, they take care of both the growing of rice and the fish extensively "for the purpose of having additional animal protein food for household consumption by farmers" (Fang Xiuzhen, p1). The additional carps also help increase income of the rice farmers. || <span style="font-family: 'Times New Roman',Times,serif;">In Oregon, commercial salmon trolling is very common within the families. Many of the "fishermen are second, third, and fourth generation in this business." It is as a family tradition and "cultural heritage passed along from generation to generation." Many times, the first catch of salmon of the season is being celebrated along the fishermen. ||
