“…Accordingly, presence–absence of A. anguilla was one of the major dissimilarities between the two management types following our SIMPER analyses (Supporting Information Table S6). In gravel pit lakes managed for recreational fisheries, a higher relative frequency of A. anguilla has previously been reported compared with natural lakes predominantly managed for commercial fisheries (Arlinghaus et al, ; Emmrich et al, ), either indicating continuous stocking of eel into angler‐managed gravel pit lakes or lower recapture rates relative to commercial fisheries. Given the poor conservation status of catadromous A. anguilla (Bark et al, ; Dekker, ), continuous stocking of this species into isolated lakes is problematic from a conservation perspective.…”

“…Species richness, number of piscivorous species, number of small‐bodied non‐game fish (Emmrich et al, ), number of threatened species [Red List of Lower Saxony, (LAVES, ), Red List of Germany (Freyhof, ) and European Red List (Freyhof & Brooks, )] and number of non‐native species in Germany (Wiesner et al, ; Wolter & Röhr, ) were calculated to describe species inventory based presence–absence data, combining electrofishing (littoral zone) and multimesh gillnet data (benthic and pelagic). Perch Perca fluviatilis (L. 1758) > 150 mm L T and eel Anguilla anguilla (L. 1758) > 500 mm L T were assigned to the piscivorous fish guild, following Emmrich et al .…”

Gravel pit lakes are novel ecosystems that can be colonized by fish through natural or anthropogenic pathways. In central Europe, many of them are managed by recreational anglers and thus experience regular fish stocking. However, also unmanaged gravel pits may be affected by stocking, either through illegal fish introductions or, occasionally, by immigration from connected water bodies. We sampled 23 small (< 20 ha) gravel pit lakes (16 managed and 7 unmanaged) in north‐western Germany using littoral electrofishing and multimesh gillnets. Our objective was to compare the fish biodiversity in gravel pit lakes in the presence or absence of recreational fisheries. Given the size of the sampled lakes, we expected species poor communities and elevated fish diversity in the managed systems due to regular stocking of game fish species. Our study lakes were primarily mesotrophic and did not differ in key abiotic and biotic environmental characteristics. Lakes of both management types hosted similar fish abundances and biomasses, but were substantially different in terms of fish community structure and species richness. Fish were present in all lakes, with a minimum of three species. Higher α‐diversity and lower β‐diversity was discovered in managed gravel pit lakes compared to unmanaged lakes. Consequently, recreational‐fisheries management fostered homogenization of fish communities, by stocking a similar set of fish species desired by anglers such as piscivorous fish and large bodied cyprinids. However, unmanaged gravel pit lakes were also affected by human‐mediated colonization, presumably by illegal fish releases. Hardly any non‐native species were detected, suggesting that recreational‐fisheries management did not foster the spread of exotic species in our study region.

“…Recently, Emmrich et al (2014) demonstrated that fish communities in the littoral zone of gravel pit lakes do not differ from those in small natural lakes, providing a first empirical evidence that suggested some potential commonness in the functioning of their community. To date, however, there is still a gap in our understanding of the environmental determinants of fish community structure in gravel pit lakes.…”

Gravel pit lakes are increasingly common, and there is an urgent need to better understand the functioning of these artificial and disconnected ecosystems. However, our knowledge of the environmental determinants of fish community structure within these types of lakes remains poor. In this study, we quantified the taxonomic diversity, fish species and life-stage composition in 17 gravel pit lakes sampled in 2012 and 2013 located in south-west France to determine the potential role of environmental variables (i.e. lake morphology, productivity, water quality and human-use intensity) as drivers of fish community structure and composition. Our results demonstrated that fish community structure significantly differed between gravel pit lakes, and we notably found that lakes managed for angling hosted higher levels of taxonomic diversity. We also found that young and large lakes supported higher native species biomass and were dominated by native European perch (Perca fluviatilis). Older, smaller and more productive lakes, located closer to the main urban area, supported a higher biomass of non-native species such as largemouth bass (Micropterus salmoides). Native and non-native sport fishing species such as northern pike (Esox lucius), pikeperch (Sander lucioperca), common carp (Cyprinus carpio) and cyprinid prey species were positively associated with fishery management effort, suggesting that management practices play also a critical role in shaping fish species composition. Overall, our study demonstrated that fish community composition followed a predictable shift along environmental gradients associated with the maturation of gravel pit lakes and the associated human practices.
