Data Envelopment Analysis (DEA) studies of fisheries usually apply output oriented capacity utilization based on physical measures. Although measures capture important input factors employed in fishing activities (such as boat size, engine power), economic directly reflect the cost inputs employed. This case study investigates whether are vital or efficiency is sufficiently well reflected solely by use The analysis makes a double bootstrap DEA technique and compares versus was chosen it allows statistical inference estimated utilization. results show that give lower than obtained However, no significant difference found utilizations between two Truncated regression models indicated such skipper experience family size did not significantly affect these at 5% level. concludes variables capable capturing essential differences vessels.
