Fishy culture in a changing world

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1925)

Animal cultures have been recognized by researchers since the mid-twentieth century, with research interest growing over past few decades. Recently, we realized that animal important ecological consequences, shaping mating preferences, adaptation to urban environments and persistence of migration routes. The study culture therefore transcends traditional, curiosity-driven research; it has real-world conservation relevance. This review centres on in fishes its intersection conservation. Culture depends upon social learning, a large literature establishes exhibit learning diverse range contexts. Moreover, laboratory experiments demonstrate capacity for fishes, while studies wild populations provide evidence natural cultures, specifically maintenance traditional routes some reef fishes. Here, argue such are likely more widespread but overlooked should be target wider effort. We also there is greater scope leverage findings from fish cultural transmission better equip reintroduced stocks behaviours might enhance post-release survival.

Cultural processes and demography: implications for conservation and beyond

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1925)

Social transmission of cultural variants in wildlife can cause population level effects with implications for conservation science, policy and practice. learning animal culture generate resilience populations through the spread adaptive behaviour but may also vulnerabilities. Distilling comprehensive management advice this field remains challenging. Animal is important defining 'units to conserve', managing human-wildlife interactions, reintroductions or translocations, influences evolutionary change. However, processes remain poorly understood. Given breadth issues which inform conservation, it timely consider underlying more detail. We coupling dynamics explore conditions under social tip a declining into growth. Simulations on model system two interacting units are used tensions between coupled demographic processes. show that even simple bias, outcomes complex. In concert urgent targeted action, we highlight need develop deeper process-based understanding field, yield fundamental principles applicable broader range encultured species.This article part theme issue 'Animal culture: changing world'.

Effectiveness of Conditioning Strategies in Improving Fish Fitness‐Related Traits

Fish and Fisheries, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

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 strategies, including environmental enrichment, life skills training and release tactic, can significantly improve fitness‐related traits, with the fitness indicator developmental stage being most important moderators for interpreting high heterogeneity among cases. The effect size of approximate indicators was marginally lower than behavioural traits. Our findings indicate necessity procedures highlight need enact context‐dependent practical conservation projects.

A Global Synthesis of Environmental Enrichment Effect on Fish Stress

Fish and Fisheries, Journal Year: 2024, Volume and Issue: 26(1), P. 131 - 154

Published: Nov. 17, 2024

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