Waste accumulation effect is an important indicator for pond design and construction as well as its operation and management in industrial fish farming. This paper investigated the effect of jet angle, jetting velocity and inner suction mode on flow filed and waste accumulation in the farming pond. The flow velocity at each selected point in the pond was measured using an ADV flow meter, then the characters of the pond flow field were studied based on the flow field graph constructed by MATLAB software, while the waste accumulation character was analyzed using image-processing method. In this study, a ‘V’ shaped variation trend of velocity along the measuring section was observed. Given the jet angle of 40°, as the jetting velocity increased, the low-velocity area adjacent to the pond center decreased and the waste accumulation effect became better, and when jetting velocity reached 0.3m/s, most of the waste got accumulated at the pond center. An optimal jet angle of 40° was obtained with the best effect of waste accumulation. It was also found that circulation mode had significant effect on flow field and waste accumulation characters. When using bottom suction mode, the radial velocity and tangential velocity near the drain port were higher than when using side suction mode, and the waste accumulation effect was also much better. The research results can be used for optimizing the hydraulic drive system in industrial fish farming pond. On the premise of not affecting the growth of cultured species, it is recommended to increase the jetting velocity as higher as possible, maintain the jet angle at 40° and adopt bottom suction mode.
