Thus, feedbacks between angler site choices, their capture efficiency (i.e., catchability), and fish population dynamics permeate through whole landscapes. Anglers then reciprocally impact local fish populations through size‐selective catch and harvest. Spatial exploitation dynamics depend on angler preferences for multiple attributes that influence their site choices. In the absence of local studies, focusing management attention on these components can be recommended if the aim is to satisfy anglers or avoid managerial or social issues that emerge from dissatisfied anglers.įreshwater fisheries are complex social‐ecological systems spatially structured by coupled feedbacks between people and nature. We conclude changes to access to fishing sites, crowding and a reduction in catch qualities, will in many cases produce dissatisfied anglers. perceived water quality, quality of social experience). environmental quality, facilities, perception of relaxation quality) also contributed to angler satisfaction but were of less importance, more variable across studies and in some cases not significant (e.g. access to fishing sites and crowding) were most related to angler satisfaction. catch rate, size of caught fish, fish harvest) and two non‐catch‐related components (i.e. The aggregated effect sizes revealed that catch‐related (i.e. A three‐level random‐effects model on Pearson's R, derived from studies relating component satisfaction to overall satisfaction assuming a sum‐of‐satisfaction model, was fitted. After identifying and screening 279 papers, we obtained K = 172 effect sizes extracted from N = 23 studies that met our inclusion criteria. Our objective was to study the catch and non‐catch‐related determinants of recreational angler satisfaction using a standardized literature search and synthesizing the literature using meta‐analytical techniques. Because of its central role in recreational fisheries management, it is important to understand what drives angler satisfaction. Angler satisfaction also shapes preferences for regulations, compliance with rules and general angler behaviours. Satisfaction is the reward that recreational anglers receive from their experiences, and it constitutes a relevant management target. Managers may well be advised to manage for specific qualities of catch (e.g., regularity of catch and larger maximum size of fish) rather than attempting to manage for high catch rates alone as the latter might not contribute to more satisfied anglers after catch rate thresholds have been passed. These findings suggest that managers cannot expect anglers to be similarly satisfied at identical catch outcomes in different social-ecological contexts, even within the same nation. Importantly, after controlling for catch outcomes and other contextual factors, anglers in the small-scale club context from north-western Germany (Lower Saxony) were, on average, more satisfied with their catch than anglers in a large-scale regional context from north-eastern Germany (Mecklenburg-Western Pomerania). Social-ecological context, trip context (e.g., season and previous catch outcomes) and angler specialization were all significant moderators of the importance of catch outcomes towards satisfaction with catch. The catch rate-satisfaction relationship showed diminishing marginal returns (i.e., more catch is better, but the marginal benefits diminish as catch increases), and the maximum fish size-satisfaction relationship was positively exponential (i.e., larger maximum fish sizes make anglers increasingly more satisfied). Catch rate and size of fish were found to positively affect catch satisfaction in both social-ecological contexts. Both fisheries are from the same eco-region and offer multi-species fisheries of a similar species mix (predominantly freshwater). We examined the relationships between catch outcomes and satisfaction using trip-level (n = 19,558) catch and harvest information from two fisheries with contrasting governance and cultural contexts within the same nation, a small club context of north-western Germany (Lower Saxony) and a regional context with largely open access in north-eastern Germany (Mecklenburg-Western Pomerania). Anglers typically prefer high catch rates and large fish, but the importance of these catch outcomes for satisfaction may differ across angler types, target species, and other contextual conditions. Angler satisfaction is a key consideration in the management of recreational fisheries.
