“…Furthermore, fish biomass in lakes is primarily driven by bottom-up effects (e.g. Hanson & Leggett, 1982; Lemmens et al , 2018; Matsuzaki et al , 2018) – a finding also revealed in our study at the aggregate biomass level, which did not differ among lake types despite radically different fish community composition. As species richness was substantially lower in unmanaged lakes, the lake type-specific small-bodied non-game species that colonized unmanaged lakes can reach higher biomasses and abundances in these lakes types compared to managed lakes.…”

20Gravel pit lakes constitute novel ecosystems that can be colonized by fishes through 21 natural or anthropogenic pathways. Many of these man-made lakes are used by 22 recreational anglers and experience regular fish stocking. Recreationally unmanaged 23 gravel pits may also be affected by fish introductions, e.g., through illegal fish 24 releases, thereby contributing to the formation of site-specific communities. Our 25 objective was to compare the fish biodiversity in gravel pit lakes with and without the 26 recent influence of recreational fisheries management. We sampled 23 small (< 20 27 ha) gravel pit lakes (16 managed and 7 unmanaged) in north-western Germany and 28 compared fish community and diversity metrics obtained using littoral electrofishing 29 and multimesh gillnet catch per unit effort data. Given the size of the lakes we 30 sampled we expected species poor communities and elevated fish diversity in the 31 managed systems due to stocking. The two lake types were primarily mesotrophic 32 and did not differ in key abiotic and biotic environmental characteristics. Both lakes 33 types hosted similar fish abundance and biomass, but were substantially different in 34 terms of the fish community structure and species richness. Fish were present in all 35 lakes with at least three species. We discovered a higher α-diversity and a lower β-36 diversity in managed gravel pit lakes compared to unmanaged lakes. Thus, 37 recreational fisheries management appeared to foster homogenization of fish 38 communities, likely because fisheries managers stock these lakes with desired fish 39 species (e.g., piscivorous fishes and large bodied cyprinids). However, we also 40 detected anthropogenic pathways in the colonization of unmanaged gravel pit lakes, 41 presumably from illegal releases by private people. Importantly, hardly any non-42 native species were detected in the gravel pits we studied, suggesting that 43 recreational fisheries management not necessarily promotes the spread of exotic 44 species. 45 Fish conservation; novel ecosystems; non-native species; fish stocking; recreational 47 fishing; fish community composition 48 49 Significance Statement 50 3Little is known about fish communities in artificially created gravel pit lakes. We 51 compared those managed by recreational fishers with those lacking fisheries 52 management in north-western Germany. We found fishes in all gravel pit lakes and 53 demonstrated a higher α-diversity but more homogenized fish communities in 54 managed gravel pit lakes compared to unmanaged lakes. We did not detect the 55 establishment of relevant abundances of non-natives fishes despite intensive 56 fisheries management. 57 58

“…Ibaraki Prefecture, which includes the Lake Kasumigaura watershed, is the top producer of some vegetables in Japan. Although these agricultural activities have supported farming livelihoods and the local economy, they have resulted in the eutrophication of Lake Kasumigaura, which is currently hypereutrophic (Takamura 2012, Matsuzaki et al 2018).…”

“…We applied this approach to examine the trade-off between crop production and water quality across 49 sub-watersheds in the watershed of Lake Kasumigaura, Japan. This watershed is highly nitrogen-loaded by agriculture (Matsumori andItahashi 2009, Shindo et al 2009), and Matsuzaki et al (2018) have recently reported that the primary production of Lake Kasumigaura is controlled by nitrogen. There is thus a need to reduce nitrogen inputs to the lake while maintaining crop production in the watershed.…”

“…Therefore, at high CED om , the realized phytoplankton biomass (measured through the residuals of the Chl a to TP relationship: TP‐corrected Chl a ) was expected to be higher than at low CED om . In turn, we expected that phytoplankton biomass (Chl a ) would also be a good predictor of fish community production (CP om ) so that a bottom‐up trophic cascade would cause increased production of the fish community in phytoplankton‐rich lakes, as described in terms of community composition and biomass (Brucet et al ; Arranz et al ; Matsuzaki et al ).…”

Fish community feeding and production rates may differ between lakes despite similar fish biomass levels because of differences in size structure and local temperature. Therefore, across-lake comparisons of the strength and direction of top-down and bottom-up fish-phytoplankton relationships should consider these factors. We used the metabolic theory of ecology to calculate size-and temperature-corrected community energy demand (CED om ) and community production (CP) of omnivorous fishes in 227 European lakes from major habitat types (MHTs) of polar freshwaters, temperate floodplain rivers and wetlands, and temperate coastal rivers. We related CED om with total phosphorus (TP)-corrected chlorophyll a (Chl a) concentrations to evaluate a potential top-down directed trophic cascade from fish to phytoplankton. Furthermore, we related Chl a with CP to demonstrate potential bottom-up effects of phytoplankton on fish. For both analyses, we added the CED of piscivorous fishes (CED pi ) as a predictor to account for potential predation effects on the omnivorous fish community. CED om was weakly positively related with TP-corrected Chl a, but the strength of the relationship differed between MHTs. In contrast, CP was consistently positively related with Chl a in the entire dataset. CED pi did not contribute to top-down or bottom-up relationships. The application of metabolic variables characterizing fish community feeding and production rates makes these results robust because the approach accounted for the usually neglected effects of fish size and temperature in across-lake comparisons. Our results suggest that bottom-up effects from phytoplankton on fish secondary production in lakes are substantially stronger than top-down effects from fish on phytoplankton biomass.Trophic cascades, that is, biotic interactions that affect more than just two adjacent trophic levels, can strongly modify the functioning of ecosystems (Carpenter et al. 1985). In lakes, a top-down trophic cascade can be induced by high abundances of zooplanktivorous fish, which exert a strong predation *Correspondence: sandra.brucet@uvic.cat and mireia.bartrons@uvic.cat Additional Supporting Information may be found in the online version of this article.
