摘要

katalang (Katsuwonus pelamis)是在Prigi渔港(PPN Prigi)登陆的主要出口商品之一。鲣鱼渔业管理采用传统的单物种Schaefer模型，该模型在技术上不适合多物种渔业，但经常被应用。反馈收获控制规则(HCR)的应用是一种针对多品种渔业成功实施和验证的替代收获策略。本研究利用2010 - 2019年在PPN Prigi捕捞的鲣鱼的渔获量数据，采用HCR反馈和Schaefer剩余生产模型两种捕捞策略估算了允许生物渔获量。模型Schaefer指出，渔获量已超过最大可持续产量()，即使在与实现最高可持续产量()相一致的捕捞死亡率()下，仍采用较低的捕捞努力量。以前已经验证的反馈HCR的应用可以作为捕捞策略的一种替代方法，用于只有混合物种数据可用的渔业。关键词:多物种渔业，收获策略，Schaefer模型，最大可持续产量，单物种方法

Pengelolaan Sumber Daya Ikan Cakalang didaratkan di Pelabuhan Perikanan Nusantara (PPN) Prigi, Trenggalek: Aplikasi Feedback Harvest Control Rule

Cakalang (Katsuwonus pelamis) is one of the leading export commodities landed at the Prigi Fishing Port (PPN Prigi). Skipjack tuna fisheries management conducted the conventional single-species Schaefer model which is often applied although it is not technically suitable for multispecies fishery. The application of feedback harvest control rule (HCR) is an alternative harvest strategy that has been successfully implemented and validated for multispecies fishery. This study estimated allowable biological catch by applying two harvest strategies, HCR feedback and Schaefer surplus production model using catch-effort data of skipjack tuna landed at PPN Prigi in the period 2010 - 2019. Model Schaefer pointed out that catches have exceeded the maximum sustainable yield () even employed low the fishing effort which was under the fishing mortality consistent with achieving MSY (). The application of feedback HCR that has been previously validated can be an alternative of harvest strategy for use in fisheries where only mixed species data is available. Key words: multispecies fishery, harvest strategy, Schaefer model, maximum sustainable yield, single-species approach
