最近出台了欧洲联盟(欧盟)条例，以阻止捕获尺寸过小的标本，目的是减少商业渔业造成的副渔获物死亡率。我们认为，我们仍然缺乏关于在大多数地中海生态系统中适当执行这些条例所需的基本信息的准确数据，包括渔业造成的真实死亡率、渔具逃逸率以及标本在被丢弃后存活的能力。我们认为，对生理生物标记物的更多依赖可能有助于支持欧盟废弃禁令(又名登陆义务)的实施所需的数据收集的所有方面，特别是在确定哪些物种应从这一政策中获得特殊豁免方面。理想情况下，这一新方法，这里称为“渔业环境和生理压力分析”(FEPSA)，将成为欧盟在《海洋战略框架指令》(2008/56/EC)中确立的渔业管理生态系统方法内的任何鱼类种群评估的重要步骤，并确认良好的环境状况。特别是，渔业局的主要目标将是将对已开发种群的生理应激源的研究应用于估计所谓的附带捕捞死亡率，其中包括与渔具相互作用后逃脱的鱼或因某种程度的伤害或生理压力而被丢弃的鱼所经历的死亡率。此处概述的方法适用于底拖网，但适用于任何其他类型的渔具，这不是一项微不足道的任务，而是收集欧盟最新渔业政策所要求的数据的要求。虽然我们同意捕鱼和相关的丢弃做法对海洋生物多样性构成的威胁需要强有力的政策干预，但我们强调，支持此类倡议所需的研究方案，包括上岸义务，应给予同等优先的地位。地中海渔业尤其如此，因为地中海渔业处于管辖边界的复杂交叉点，存在许多额外的生态系统威胁，包括广泛的污染、温度变化和缺氧，与更北部气候的渔业和物种相比，历史上对其研究不足。
Recent European Union (EU) regulations have been introduced to discourage the capture of undersized specimens with the aim of reducing the bycatch mortality imposed by commercial fisheries. We argue that we still lack accurate data regarding basic information required to properly implement these regulations for most Mediterranean ecosystems, including the true mortality imposed by fisheries, escape rates from fishing gears and the capability of specimens to survive following discard. We suggest that additional reliance on physiological biomarkers could assist in all aspects of the data collection required to support implementation of the EU discard ban (aka landing obligation), particularly in determining which species should receive special dispensation from this policy. Ideally, this new approach, here termed the ‘Fisheries Environmental and Physiological Stress Analysis’ (FEPSA), would become an important step for any fish stock assessment within the ecosystem approach to fisheries management and the recognition of Good Environmental Status, as established by the EU in the Marine Strategy Framework Directive (2008/56/EC). In particular, the main goal of FEPSA would be applying the study of physiological stressors to exploited stocks to estimate the so-called collateral fishing mortality, which includes the mortality experienced by fish that escape after interacting with fishing gears or that are discarded, with some degree of injury or physiological stress. The approach outlined here, which is described for bottom trawls but adaptable to any other type of fishing gear, is not a trivial undertaking but is a requirement for collecting the data required by recent EU fisheries policies. While we agree that the threats to marine biodiversity posed by fishing and associated discard practices require strong policy interventions, we emphasize that the research programs needed to support such initiatives, including the landing obligation, should be given equal priority. This is particularly true for Mediterranean fisheries, which are at a complex intersection of jurisdictional boundaries, numerous additional ecosystem threats including widespread pollution, thermal variation and hypoxia, and are historically understudied as compared to fisheries and species in more northern climates.
