This paper deals with a problem of squid sucker adsorption as an obstacle to the collecting operation after catching squid. First, the adsorption mechanism is clarified and a model of single sucker's sucking force is built Next, by the mechanical model of a squid on the collecting chute constructed in this paper, each physical parameter and friction force due to sucker adsorption of live squid are measured. Then, the required velocity and the required flow rate are derived from the mechanical model as mechanical conditions that allow smooth squid flowing. Based on these results, the influence of sucker adsorption to the collecting operation is evaluated quantitatively, and it is confirmed that sucker adsorption is a serious problem. Furthermore, using the required velocity curve, a systematic method of choosing flow rate and setting suitable velocity for the rate is proposed.
