AUTOMATIC WEIGHT AND QUALITY GRADING OF WHOLE PELAGIC FISH

Abstract

Despite good availability of pelagic fish, the Norwegian pelagic enterprises are suffering from both overcapacity and low margins. The reasons for this situation are diverse, e.g. high labor costs, trade barriers and long distances to the markets. In order to cope with competition from other countries, the most important issue is to lower labor costs while maintaining quality. In this article we describe a proof-of-concept prototype of an automated system for weight and quality grading of pelagic fish using a multi-modal machine vision system combined with robotized sorting. This system can potentially replace the majority of the manual operators needed today.
