Abstract

Although conditioning strategies are widely used to increase fish post-release adaptability in stock enhancement projects, their effectiveness has not been systematically evaluated. Using a global-scale meta-analysis, we demonstrate that three major conditioning strategies, including environmental enrichment, life skills training and release tactic, can significantly improve fish fitness-related traits, with the fitness indicator and developmental stage being the most important moderators for interpreting the high heterogeneity among cases. The effect size of approximate fitness indicators was marginally lower than that of post-release behavioural traits. Our findings indicate the necessity of conditioning procedures and highlight the need to enact context-dependent strategies in practical conservation projects.

调节策略在改善鱼类适应性相关性状中的有效性

尽管调节策略被广泛用于提高鱼类在种群增加项目中的释放后适应性，但其有效性尚未得到系统的评估。利用全球尺度的元分析，我们发现环境富集、生活技能训练和释放策略三种主要的条件调节策略可以显著改善鱼类的适应性相关性状，而适应性指标和发育阶段是解释案例间高度异质性的最重要调节因子。近似适应度指标的效应值略低于释放后行为特征的效应值。我们的研究结果表明了调节程序的必要性，并强调了在实际保护项目中制定情境依赖策略的必要性。

期刊介绍： Fish and Fisheries adopts a broad, interdisciplinary approach to the subject of fish biology and fisheries. It draws contributions in the form of major synoptic papers and syntheses or meta-analyses that lay out new approaches, re-examine existing findings, methods or theory, and discuss papers and commentaries from diverse areas. Focal areas include fish palaeontology, molecular biology and ecology, genetics, biochemistry, physiology, ecology, behaviour, evolutionary studies, conservation, assessment, population dynamics, mathematical modelling, ecosystem analysis and the social, economic and policy aspects of fisheries where they are grounded in a scientific approach. A paper in Fish and Fisheries must draw upon all key elements of the existing literature on a topic, normally have a broad geographic and/or taxonomic scope, and provide general points which make it compelling to a wide range of readers whatever their geographical location. So, in short, we aim to publish articles that make syntheses of old or synoptic, long-term or spatially widespread data, introduce or consolidate fresh concepts or theory, or, in the Ghoti section, briefly justify preliminary, new synoptic ideas. Please note that authors of submissions not meeting this mandate will be directed to the appropriate primary literature.
