The economic incomes per cruise of two specimen boats owners were permitted to be traced during two periods, May-June and September-December in 2003. The average income of fishing cruise which did not encounter dolphins was $NT 7327 dollars (SD=643 n=29 trips). The average income of fishing cruise which have encountered dolphins but no interruptions was $NT 7901 dollars (SD=1581 n=13 trips). The average income of fishing cruise which depredated by dolphins was NT 3137 dollars (SD=419 n=6 trips). The daily average income was $NT 6959 (SD=4211 n=48) per day. The cetacean interference result in a significant economic decrease.

另外，鲸豚干扰渔获的损益评估依据2003两艘样本船在5-6月，及9-10月每日作业及盈收状况的追踪发现，没有碰到海豚的每日作业平均收益为NT 7327元(SD=643 n=29)，碰到海豚但无干扰的每日作业平均收益为NT 7901元(SD=1581 n=13)，有海豚干扰的每日作业平均收益为NT 3137元(SD=419 n=6)，全部作业收益每日平均为NT 6959元(SD=4211 n=48)，被鲸豚干扰后之渔获收益较未遇见鲸豚或遇见鲸豚却未被干扰情况下减少。
