“…This study showed that P. antipodarum share in the diet of studied benthivorous fish was very low throughout all seasons, although the contribution of other molluscs to the diet of some fish was significant. Similar results were obtained in previous studies of benthivorous fish performed during autumn in several Lithuanian lakes recently invaded by P. antipodarum (Rakauskas et al 2016), or studies of various fish species in other regions (Bersine et al 2008, Brenneis et al 2011. Rakauskas et al (2016) revealed that in temperate lakes the main benthivorous fishes actually avoid P. antipodarum as prey.…”

“…During repeated macroinvertebrate surveys within 2003-2006 P. antipodarum was not detected in Lake Dusia (Gumuliauskaitė unpublished *** ), but when the surveys were renewed in 2010, the snail was already found to constitute over 30% of macroinvertebrate abundance and biomass (Butkus et al 2012, Rakauskas et al 2016, 2018. These findings indicated that P. antipodarum invaded the lake between 2007 and 2009, thus this period was excluded from our study.…”

“…Secondly, in invaded ranges, P. antipodarum reproduces parthenogenetically (Dybdahl andDrown 2011, Hamada et al 2013). Thirdly, due to its hard shell, small size, and low nutritional value the species is avoided by the majority of native predators (Bersine et al 2008, Brenneis et al 2011, Rakauskas et al 2013, 2016. Furthermore, if preyed upon by fish, some individuals of P. antipodarum are able to survive the digesting process and fully recover after evacuation (Vinson and Baker 2008, Brenneis et al 2011, Rakauskas et al 2016.…”

“…This paper addresses the potential impacts of P. antipodarum on the fisheries in a temperate mesotrophic lake. A conjunction of the facts that (1) P. antipodarum may become abundant, (2) it consumes a substantial portion of lake primary production, and (3) it is not proportionally targeted by native predators, raises a legitimate concern that it may reduce the direct energy flow to higher trophic levels, leaving part of the primary production blocked from ascending further up the trophic chain (Rakauskas et al 2016(Rakauskas et al , 2018.…”

Background. To date, numerous studies of the impact of snail Potamopyrgus antipodarum (Gray, 1843) on invaded ecosystems have been conducted. However, the majority of such studies intended to assess changes induced in macroinvertebrate assemblages, while the possible effects of P. antipodarum on higher trophic levels have not hitherto been studied. Of particular interest from the point of view of fisheries management is the elucidation of how this invasive snail can alter the energy flow towards higher trophic levels. When abundant, P. antipodarum consumes a substantial part of the primary production, but it is poorly consumed by native fishes. Consequently, part of its assimilated energy may become locked in lower trophic levels and fail to reach higher levels directly. Therefore, invasion of this snail may decrease fish production. Materials and methods. Several years after establishment of P. antipodarum in a temperate mesotrophic Lake Dusia, we assessed: (1) changes in the biomass of littoral macroinvertebrates (proxy to secondary production), (2) assimilation of P. antipodarum by benthivorous fish (energy flow), and (3) changes in growth and catches of littoral benthivorous fish (fish production). All the analyses were based on a merger of "grey" literature and original data during the pre-and post-invasion periods. Results. There was an evident increase in the biomass of littoral macroinvertebrates, and the assemblage changed from crustacean-to gastropod-dominated due to over-domination of P. antipodarum. However, P. antipodarum did not replace the native prey of fish. Moreover, a marked decrease was recorded in littoral fish growth and catches after the invasion of P. antipodarum. Conclusion. Dense populations of P. antipodarum may reduce the channelling of primary production towards higher trophic levels and, consequently, the invasion may threaten fisheries of temperate mesotrophic lakes.

Invasive freshwater snails are less sensitive to population density than native conspecifics

Understanding how and why some species or lineages become invasive is critically important for effectively predicting and mitigating biological invasions. Here, we address an important unanswered question in invasion biology: do key life‐history traits of invasive versus native lineages within a species differ in response to key environmental stressors? We focus on the environmental factor of population density, which is a fundamental characteristic of all populations, and investigate how changes in density affect native versus invasive Potamopyrgus antipodarum (New Zealand mudsnail). P. antipodarum has invaded 39 countries and detrimentally affects invaded environments. Previous studies of native and invasive populations and from laboratory experiments have demonstrated that growth and reproduction of P. antipodarum is sensitive to population density, though whether and how this sensitivity varies across native versus invasive lineages remains uncharacterized. We quantified individual growth rate and reproduction in P. antipodarum from multiple distinct native and invasive lineages across three different population density treatments. The growth of native but not invasive lineages decreased as density increased. There was no differential effect of density treatment on embryo production of invasive versus native snails, but a significantly higher proportion of snails were reproductive in high density compared to intermediate density for invasive lineages. In native lineages, there were no significant differences in the relative frequency of reproductive snails across density treatments. While the extent to which these results from our laboratory study can be extrapolated to the more complex natural world remain unclear, our findings are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become successful invaders. Our findings also align with previous studies that show that invasive P. antipodarum lineages exhibit a relatively wide range of tolerance to environmental stressors.
