Abstract
The stress-coping ability (SCA) is one of the core aspects of fish welfare and is of vital importance for fish production in the aquaculture industry and for fish fitness in hatchery release. Environmental enrichment (EE), a method of introducing external stimuli into the husbandry environment, has been recently proposed to improve fish SCA, but the present experimental evidence is mixed and the reasons for these discrepancies are unclear. Here, we conducted a global meta-analysis using a data set that consists of 1786 cases from 107 studies across 42 fish species to solve this problem. Overall, we found that enriched fish had significantly higher SCA than control fish, reflected in either basal stress levels or stress responses. Meta-regression analyses showed that specific subgroups of enrichment type, fish developmental stage, stress category, stress duration, stress place, sample tissue, and indicator system showed significant positive EE effects on SCA. Multi-model inference indicated that the indicator system, fish developmental stage, stress characteristic, and enrichment mode are important drivers for the high heterogeneity among effect sizes. These results highlight the importance of introducing EE into the rearing systems, which will not only increase the welfare of aquaculture fish but also improve the ecological adaptability of released fish. The comprehensive knowledge obtained in this analysis will provide insight into fish ontogenetic plasticity and its responses to EE and have important implications for improving the production cycle in fish aquaculture and fisheries conservation.

stress.type: the type of stressors, which is divided into physical stressor, chemical stressor, social stressor, mixed stressor, and none.
stress.category: the sub-category of stress type. Each stress category is further categorized into one of above five stress types. In detail, “physical stressor” includes water-level lower, novel environment, chasing, forced swimming, and transport; “chemical stressor” includes air exposure, hypoxia, anesthesia, and drug injection; and “social stressor” includes social deprivation, pathogen challenge, and predation. The “mixed stressor” indicates the fish is encountered two or more single stressors, i.e. “mixture”, whereas the “none” indicates no stressor is encountered by fish, i.e. basal stress level.
stress.duration: the exposure duration of stressors, which is divided into none, acute, and chronic. Among them, “none” indicates no stressor is encountered by fish, i.e., basal stress level; “acute” indicates the fish encounters a stressor only once; and “chronic” indicates the fish encounters a single stressor or mixed stressors for two or more repeats.
stress.place: the place where fish encounter stress, which is divided into none, home tank, and other tank. The “none” indicates no stressor is encountered by fish, i.e., basal stress level.

if.recovery: It indicates whether the indicator value recovered to the basal value or lower than peak value in the stress response, which is divided into yes, no, and no-info. The “no-info” means we do not assure it based on the original paper.
indicator.stage: we refer the first-level classification of fish stress parameters as “indicator stage”, and roughly divide it as primary, secondary, tertiary, and social interaction.
indicator.process: we refer the second-level classification of fish stress parameters as “indicator process”, and each indicator process is classified into one of four “indicator stage” items. In detail, primary stage includes Hypothalamic-Pituitary-Interrenal axis (i.e., HPI axis), Hypothalamic-Sympathetic-Chromaffin cell axis (i.e., HSC axis), and Other Neurotransmitters, Neuroendocrine peptides, and Hormones (i.e., ONNH). Secondary stage inculdes blood changes, oxygen uptake, and Other Physiological Processes (i.e., OPP). Tertiary stage mainly includes anxiety-like behavior. Social interaction includes body damage, and aggression.
indicator.measurement: we refer the third-level classification of fish stress parameters as “indicator measurement”, and these parameters are extracted from original publications and are classified into specific “indicator process” items.
