Distributions of Hooking Position in a Mouth for Sode Hooks Derived from the Stochastic Model of Hooking Mechanism
2010
Shimizu, Susumu
The distributions of hooking positions in a mouth for sode hooks were obtained with pole and line fishing experiments in a water tank in order to analyze hooking phenomena. The hooking positions of smaller hooks are almost distributed in a esophagus or near a fish snout, and those of larger hooks are almost distributed about the center of a mouth cavity back. The distributions of hooking position in a mouth derived from a stochastic model of hooking mechanism were fitted well on the observed distributions for smaller hooks. However, in the case of larger hooks, the estimated distributions were not fitted on the observed distributions. It appears that the estimated distributions for large hooks are different from observed ones because the entrance size of the esophagus is not included in the model.
