台风引起网箱内水体动荡模拟装置的制作与应用

Production and Application of In-cage Water Unrest Simulator During Typhoon Occurrence

在水产养殖业中,每年台灾过后,都会造成海水网箱养殖鱼类不同程度的损失,为此设计制作了一件拆装方便、操作简单,在室内方便可行的水体激烈动荡模拟装置,以用于研究台风期间风浪引起海水养殖网箱内水体激烈动荡对养殖鱼类的影响.该模拟装置对大黄鱼(Pseudosciaena crocea)24 h不同强度的动荡测试结果表明,水体动荡模拟器重复性佳、操作简便、无水体死角,且可以通过调控水体动荡的幅度模拟不同强度台风引起的风浪,适合进行台风引起海水养殖网箱内水体动荡的室内模拟实验.

In the field of aquaculture industry,various kinds of fish which are cultured in the fish-farming boxes filled with sea water suffer revenue loss arising from the seasonal typhoon.To tackle this problem,in this paper an easy-to-use simulator is designed,which is intended to find out how the fish breeding is affected by the unrest water triggered by the typhoon.A 24-hour experiment is conducted,based on using the waves of different intensity,to observe the culture effect of Pseudosciaena crocea.A variety of advantages can be noted for the developed simulator,including good reusability,easy operating,water recycling.The proposed device is designed for indoor experiment use and suitable for simulating the internal water turbulence triggered by the typhoon with varying intensities in the farming boxes.
