Liu Zhi-hong~1 Li Juan~2 Liu Xing-qiao~2 (1.Advanced gacational Technology School of Huaian City Radio and TV University of Huaian City,Huaia 223001,China;2.College of Electrical and Information Engineering of Jiangsu university,Zhenjiang 212013,China)  
This paper introduces a system that monitor and control the pathological changes of the fish carries on the aquiculture.Through the powerful image processing function of MATLAB software,putting up median filter,gray processing and binary processing to the reading image. Then on the theory of shrink and expand,editing program,dealing with binary image shrink and expand times to wipe off impurity.At last,through the concept of area square,counting up the number of white pixel,compared with the covariance data,can immediately judge whether appears the pathological changes of the fish.
