工业化智能化循环水养殖,现代水产养殖业发展的新趋势 IndustrializedSmart RAS Fish Farming- A new Trend in Modern Aquaculture 再循环水产养殖系统(RAS)技术是一种以地面为基础养鱼的新趋势。渔场的水通过使用泵、机械清洁系统和生物过滤器进行回收利用。这项技术可以用于许多不同鱼类的养殖,在许多地区渔业养殖的应用正在迅速增加。 再循环可以根据被循环的水量进行不同强度的执行。一些农场使用的是超级集约养殖系统,安装在一个封闭的建筑内,每年生产1公斤鱼仅需要使用0.3立方米的新水。因此,再循环水系统的引入,使对水的需求将减少95%以上。 传统养鱼完全依赖于外部环境条件,如河流的水温、水的清洁度、氧气水平,或顺流漂浮的杂草和树叶,阻塞入口滤网等等。在再循环系统中完全可以消除这些外部因素。RAS使养殖户能够控制生产过程中的所有参数。 控制这些如水温、氧饱和度、光等参数,使之能够为鱼的生长提供稳定和最适合的条件,又减少压力,让鱼更好地生长。这个特性的主要优势在于可以制定精确的生产计划,鱼销售到市场的确切时间将可以预测。这种方式有利于对养殖场进行全面的管理,同时加强市场竞争力。 集约化养鱼需要密切监测和控制生产,为了始终在鱼的生长过程中保持最佳条件。同时,自动投料也可以成为中央控制系统集成的一部分。这使得喂养的时间能够准确地与氧气含量进行协调,因为喂食期间耗氧量会增加。 RAS是基地养鱼的未来,因为它与传统的渔业养殖相比具有更多的优势。目前,大多数的基地渔业养殖的发展都与RAS技术息息相关,毫无疑问,它将在水产行业的未来扮演一个十分重要的角色。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
