Predation by invasive signal crayfish on early life stages of European barbel may be limited

Abstract: 1.To determine whether or not signal crayfish Pacifastacus leniusculus and native white-clawed crayfish Austropotamobius pallipes prey on European barbel Barbus barbus eggs, interstitial free-embryos and emergent larvae, experiments were undertaken in salmonid (substratum) incubators (six treatments, four controls) fitted with video recorders. 2.No corpses or remains of emergent barbel larvae or eggs, or parts thereof, were observed in any of the incubators containing buried eggs, and no emergent larvae showed… Show more

“…Pond dredging, intended to remove invasive plants had the unexpected result of creating a population explosion by pumpkinseed Lepomis gibbosus ( Van Kleef et al, 2008 ). Food web structures can be impacted by the introduction of omnivorous species ( Sievers, 2012 ), which force native fish to shift their foraging behaviour ( Copp et al, 2017a ) and invasive predators, such as non-native crayfish, which affect the recruitment of native fish ( Copp et al, 2017b ; Edmonds et al, 2011 ) and reduce richness of invertebrates and aquatic plants ( Jones et al, 2018 ). The invasive American mink Neovison vison , can exert enormous predation pressure on small riparian mammals (e.g.…”

“…De Californische rivierkreeft (Pacifastacus leniusculus) komt alleen lokaal voor in het oosten en zuiden van Nederland (Figuur 1E) [2,18]. Deze soort staat bekend als een boosdoener in het buitenland [97][98][99][101][102][103][104][105][106] en hiervan wordt verwacht dat deze ook voor problemen in Nederland kan zorgen. Invasieve kreeften zijn vaak niet kieskeurig wat betreft habitat en dieet [19][20][21][22] en kunnen in hoge dichtheden enorme veranderingen teweegbrengen in het ecosysteem [1,14].…”

“…Op vergelijkbare wijze lijkt de Californische rivierkreeft agressiever te zijn dan inheemse rivierkreeften tegenover donderpadden en zijn ze ook altijd dominant als het gaat om schuilplekken [92,100]. Het effect van Californische rivierkreeften op vispopulaties is echter veel uitgestrekter, aangezien verschillende studies aantonen dat deze soort een breed scala aan vissoorten negatief beïnvloedt [101][102][103][104][105][106].…”
