摘要

直到最近,商业渔业一直被认为是导致箭亚纲鱼类数量下降的主要驱动因素。然而,随着人们认识到在某些地区,休闲垂钓的鳞鳃类渔获量可能与商业渔获量相当或超过商业渔获量,这种看法开始发生转变。许多休闲垂钓鞘鳃类鱼类的做法是大量参与捕捞和释放垂钓。然而,高释放率并不一定等同于高存活率。因此,为了帮助准确评估休闲垂钓对鳞鳃亚纲动物的潜在影响,我们试图总结和整合与休闲垂钓相关的特定风险因素、相关死亡率以及垂钓者行为与已识别风险因素相关的现有信息。我们将与垂钓有关的主要影响分为两类:伤害引起的影响和生化干扰引起的影响;对每一类影响进行了总结,并概述了由这些影响引起的主要致死和亚致死结果。这些结果包括释放后的直接和延迟死亡率、行为恢复期(可能会增加捕食风险)、慢性健康影响以及捕获引起的产仔和流产。此外,我们还详细介绍了一系列垂钓方法和设备,包括鱼钩类型、摘钩和浸泡(即暴露于空气中),以及有氧范围、呼吸模式、体型和物种特定行为等特定内部和内部因素,这些因素可能会影响受伤率和/或死亡率,因此在评估垂钓相关影响时应加以考虑。然后,我们利用这些数据为垂钓者和政策制定者提供了一系列可行的建议,这些建议将有助于减少休闲垂钓对这些神秘动物的种群影响。

A review of elasmobranch catch-and-release science: synthesis of current knowledge, implications for best practice and future research directions.

Until relatively recently commercial fisheries have been considered the main driving factor for elasmobranch population declines. However, this belief has begun to shift with the realization that recreational elasmobranch catches may equal or exceed commercial catches in some regions. Many recreational angling fisheries for elasmobranchs involve high participation in catch-and-release angling practices. However, high release rates may not necessarily equate to high survival rates. Therefore, to assist accurate assessment of the potential impact of recreational angling on elasmobranchs, we attempted to summarize and integrate currently available information on specific risk factors associated with recreational angling, alongside associated mortality rates, as well as information on angler behaviour as it relates to identified risk factors. We categorized the major angling-related effects into two groups: injury-induced effects; and biochemical disruption-induced effects; providing a summary of each group and outlining the main lethal and sub-lethal outcomes stemming from these. These outcomes include immediate and delayed post-release mortality, behavioural recovery periods (which may in-turn confer increased predation risks), chronic health impacts and capture-induced parturition and abortion. Additionally, we detailed a range of angling practices and equipment, including hook-type, hook removal and emersion (i.e. air exposure), as well as inter- and intra-specific factors, including aerobic scope, respiratory mode, body size and species-specific behaviours, which are likely to influence injury and/or mortality rates and should therefore be considered when assessing angling-related impacts. We then utilized these data to provide a range of actionable recommendations for both anglers and policymakers which would serve to reduce the population-level impact of recreational angling on these enigmatic animals.

期刊介绍: Conservation Physiology is an online only, fully open access journal published on behalf of the Society for Experimental Biology. Biodiversity across the globe faces a growing number of threats associated with human activities. Conservation Physiology will publish research on all taxa (microbes, plants and animals) focused on understanding and predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors. Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales. We also welcome research towards developing and refining strategies to rebuild populations, restore ecosystems, inform conservation policy, and manage living resources. We define conservation physiology broadly and encourage potential authors to contact the editorial team if they have any questions regarding the remit of the journal.
