Aquaculture is the fastest growing food production sector globally, encompassing freshwater and marine species reared across highly variable farming contexts. As production has intensified, the welfare of farmed fish has gained increasing recognition as an essential contributor to the sustainability of the sector. Environmental enrichment has emerged as a promising welfare management tool that aims to improve fish welfare and deliver potential production benefits by promoting species-appropriate behaviour and reducing chronic stress. Farmed fish exist within dynamic systems shaped by fluctuating environmental conditions, shared space with conspecifics and, in some cases, multiple species, and variable management regimes. As a result, the effective implementation of enrichment remains highly context dependent. This presentation synthesises current knowledge on environmental enrichment across five categories, namely physical, sensory, dietary, occupational, and social enrichment, and evaluates their capacity to produce measurable improvements in physiological and behavioural indicators of welfare. Enrichment strategies are also assessed in terms of their practicality and feasibility across different farming contexts, identifying areas where enrichment is already integrated into practice and where further innovation is required. A goal-oriented framework is then presented that outlines a stepwise process for aligning welfare objectives with appropriate enrichment strategies according to species, system, and operational context. This presentation argues that environmental enrichment should be considered an integrated component of welfare management, reflecting the realities of fish life in dynamic aquaculture systems.
