工業化智能化循環水養殖，現代水產養殖業發展的新趨勢 IndustrializedSmart RAS Fish Farming- A new Trend in Modern Aquaculture 再循環水產養殖系統(RAS)技術是一種以地面為基礎養魚的新趨勢。漁場的水通過使用泵、機械清潔系統和生物過濾器進行回收利用。這項技術可以用于許多不同魚類的養殖，在許多地區漁業養殖的應用正在迅速增加。 再循環可以根據被循環的水量進行不同強度的執行。一些農場使用的是超級集約養殖系統，安裝在一個封閉的建筑內，每年生產1公斤魚僅需要使用0.3立方米的新水。因此，再循環水系統的引入，使對水的需求將減少95%以上。 傳統養魚完全依賴于外部環境條件，如河流的水溫、水的清潔度、氧氣水平，或順流漂浮的雜草和樹葉，阻塞入口濾網等等。在再循環系統中完全可以消除這些外部因素。RAS使養殖戶能夠控制生產過程中的所有參數。 控制這些如水溫、氧飽和度、光等參數，使之能夠為魚的生長提供穩定和最適合的條件，又減少壓力，讓魚更好地生長。這個特性的主要優勢在于可以制定精確的生產計劃，魚銷售到市場的確切時間將可以預測。這種方式有利于對養殖場進行全面的管理，同時加強市場競爭力。 集約化養魚需要密切監測和控制生產，為了始終在魚的生長過程中保持最佳條件。同時，自動投料也可以成為中央控制系統集成的一部分。這使得喂養的時間能夠準確地與氧氣含量進行協調，因為喂食期間耗氧量會增加。 RAS是基地養魚的未來，因為它與傳統的漁業養殖相比具有更多的優勢。目前，大多數的基地漁業養殖的發展都與RAS技術息息相關，毫無疑問，它將在水產行業的未來扮演一個十分重要的角色。Recirculation Aquaculture System (RAS) technology is a new and moderntrend in land based fish farming. The water in the fish farm is recycled by theuse of pumps, mechanical cleaning systems and biological filters. Thetechnology can be used for many different fish species and is increasingrapidly in many areas of the fish farming sector. The systems vary from hugeplants generating several thousand tonnes of fish per year to smallersophisticated systems used for fry and fingerling productions. Recirculation can be carried out atdifferent intensities depending on how much water is recirculated. Some farmsare super intensive farming systems installed inside a closed insulatedbuilding using as little as 0,3 m3 of new water per kilo of fish produced peryear. Other systems are traditional outdoor farms using around 1 m3 of newwater per kilo of fish produced per year. A traditional flow-through system fortrout will typically use around 30 m3 per kilo of fish produced per year. So,introduction of RAS easily reduces the need for water by more than 95%. Traditional fish farming is totallydependent on external conditions such as the water temperature of the river,cleanliness of the water, oxygen levels, or weed and leaves drifting downstreamand blocking the inlet screens, etc. In a recirculated system these externalfactors are eliminated. RAS enables the fish farmer to control all parametersin the production. Controlling parameters such as watertemperature, oxygen saturation, light etc. gives stable and optimal conditionsfor the fish, which again gives less stress and better growth. These stableconditions result in a steady and foreseeable growth pattern that enables thefarmer to precisely predict when the fish will have reached a certain stage orsize. The major advantage of this feature is that a precise production plan canbe drawn up and that the exact time the fish will be ready for sale to themarket can be predicted. This favours the overall management of the farm andstrengthens the ability to market the fish in a competitive way. Intensive fish farming requires closemonitoring and control of the production in order to maintain optimalconditions for the fish at all times. In the modern farm, a smart centralcontrol system will monitor and control oxygen levels, temperature, pH, waterlevels and motor functions. If any of the parameters moves out of the presethysteresis values, a start/stop process will solve the problem. If the problemis not solved automatically, an alarm will start. Also, automatic feeding canbe an integrated part of the central control system. This allows the timing ofthe feeding to be coordinated precisely with a higher dosage of oxygen as theoxygen consumption rises during feeding. RASis the future in land based fish farming because it gives so many advantagescompared to traditional fish farming. Today most of the land based fish farmingdevelopment concerns RAS technology, and there is no doubt that
