This paper describes a non-traditional fisheries management concept and an indicator-based framework to encourage and guide management of invasive lionfish (Pterois spp.) fisheries in the temperate and tropical western Atlantic. We introduce the concept of optimum lionfish yield (OLY)—an extension of the concept of ecologically sustainable yield—which considers local ecological health in the establishment of fishery management targets. In contrast to traditional fishery targets, OLY is a target exceeding maximum sustainable yield (MSY) that still provides relatively high sustainable yield, but further contributes to population suppression beyond what is achievable through targets at or below MSY. Thus, OLY seeks to balance management trade-offs from both natural resource and invasive species management perspectives. In this study, we developed an age-structured population model and applied the concept of OLY to quantify targets to initiate management of a nationally-managed lionfish fishery in Belize. Socioeconomic and ecological data were used as indicators to formulate OLY values. The model indicates that lionfish in Belize are biologically robust to fishing pressure, which corroborates previous findings. Fishing lionfish at rates above MSY levels is expected to substantially reduce population abundance, much more so than fishing at rates below MSY levels, while having relatively minimal impacts on yield. Population suppression can be further enhanced by reducing size at selection, but this is expected to be done at a significant cost to landings. Together, these data support continued establishment of (managed) commercial lionfish fisheries throughout the invaded range to provide an alternative sustainable fishery resource and serve as a means of national- and international-level control. While the concept and framework described here is introduced for management of invasive lionfish, it could be applied to management of other invasive species, both aquatic and terrestrial.

本文介绍了一种非传统的渔业管理概念和一个基于指标的框架，以鼓励和指导对侵入性fish鱼（Pterois）的管理。spp。）在温带和热带西大西洋的渔业。我们介绍了最佳l鱼产量（OLY）的概念，它是生态可持续产量概念的延伸，它在制定渔业管理目标时考虑了当地的生态健康。与传统的渔业目标相比，OLY是一个目标，该目标超过了最大可持续产量（MSY），该目标仍可提供相对较高的可持续产量，但进一步有助于抑制人口数量，超出了达到或低于MSY的目标所能实现的目标。因此，OLY试图从自然资源和入侵物种管理的角度平衡管理权衡。在这项研究中，我们开发了年龄结构的种群模型，并应用了OLY的概念来量化目标，以启动对伯利兹国家管理的l鱼渔业的管理。社会经济和生态数据被用作制定OLY值的指标。该模型表明，伯利兹的fish鱼在生物学上对捕捞压力具有鲁棒性，从而证实了先前的发现。预计以高于MSY水平的比率捕捞l鱼会大大降低种群数量，远比以低于MSY水平的比率捕捞的捕捞量更多，同时对产量的影响相对最小。通过减少选拔人员的规模，可以进一步加强对人口的压制，但是这样做的代价是着陆成本很高。这些数据加在一起，支持在整个入侵范围内继续建立（管理）商业l鱼渔业，以提供替代性可持续渔业资源，并作为国家和国际一级的控制手段。
