This study was undertaken to describe the system model of fishing gears (i.e. trap) by a linear Sampled-data system. As a result of it, the variation of the trap model can be described by a state function uniformly and it is enough to estimate the coefficient matrix when considering its dynamic characteristic. For the triple trap experiment, one thousand "motugo" Pseudorasbora pava were prepared and two hundred of them were released in their several parts of the triple trap by turns, Time series variation of the number of fish was recorded by VTR. According to the result, the unique coefficient matrix of this experiment was estimated by the curve fitting method applying the computer simulation technique and it was highly acceptable.
