Abstract

In the present study, we developed an estimation model for the production values of kelp products with the aim of revitalizing the kelp-farming business. Production values of two primary products, Long and Round, are calculated from expected unit price and the number of kelp units to be harvested. Production values of three secondary products, Offcut, Edge, and Root, are calculated from estimated values of the two primary products.   In terms of product quality, grade evaluation system has been applied to every primary product in Fukushima-cho, Hokkaido. This model has a matrix that represents the occurrence rate of each grade. The matrix values are based on the analysis of hundreds of samples. Expected mean unit price and coefficients of variation can be calculated from production value of each grade in the past 8 years.   The production simulation based on the proposed model will optimize expenditure and increase the profits of kelp-farming fishermen.
