2013年1 - 12月对孟买新渡轮码头(NFW)上岸中心5种优势头足类幼鱼的上岸进行了经济评价。记录的优势头足类渔业包括1种乌贼(Uroteuthis (P) duvaucelii)、3种墨鱼(Sepia elliptica、Sepia pharaonis、 seppiella inermis)和1种章鱼(Cistopus indicus )，共占头足类总登陆量的98%。如果允许幼鱼在第一次成熟时长到长度(Lm)/Lmean，利用生物经济模型计算出的年总经济收益为33.22亿卢比，生物量收益为4995 t /年。在5种中，C。籼稻贡献最大，平均幼鱼捕获量为64.07%，其次是U。(P) duvaucelii (26%)， S。椭圆 (23.63%)， S。 S。Pharaonis (12.85%)。在这些资源上，在S中。 inermis, both LM equals Lmean indicates breakeven point for the species. The study revealed that peak spawning season of these species coincides with peak juvenile landings which may result in reduction of overall size range thus will lead to loss of fishery in economic as well as ecosystem regime. The study indicates the improvement of harvest biomass by 2.95 times which would result in generating additional revenue to the fishers by a margin of 3.71 times; if juveniles are allowed to grow up to Lm/ Lmean whichever is greater.
Based on finding of present study management measures such as temporary fishing holidays at juveniles fishing grounds, feeding grounds and spawner abundance grounds which in turn allow these high valued species to contribute to the fishery with high economic gain and sustainable utilization of the resources may be adopted.
