Development of a Fish Species Differentiation System of Dressed Puffer (Migaki) Based on Features of its Body Surface Color

Abstract

The purpose of a study was to maintain skill levels among middle traders for distinguishing the species of puffers and improve food safety and security . The models for distinguishing the species of puffers by capturing the color characteristics of dressed meat samples were developed . Meat samples from 7 species (dressed ocellate puffer , purple puffer , etc . ) were used ; these samples consisted of 110 as a basis .Discriminate models were made up of fish species as the criterion values and the color combinations as the predictor variables , respectively . An evaluation experiment using 20 specimens of each meat from 7 species correctly identified at least 93.5% of the dressed meat samples . Thus , the potential usefulness of the models was confirmed .
