“…There is a proposal to attempt to reduce carp abundance in Australia by releasing cyprinid herpesvirus 3 (CyHV-3) to act as a biological control agent (McColl et al, 2016(McColl et al, , 2017McColl and Sunarto, 2020). Despite the apparent efficacy of the virus in some situations, there are a range of concerns for the release of the virus, from co-evolution and non-target effects (although these appear unlikely), low efficacy of the virus due to fecundity and resistance (Mintram et al, 2020), through to indirect ecological ramifications (including creating anoxic water conditions following death of the fish) (Kopf et al, 2019). It is hoped that release of the CyHV-3 will reduce carp abundances in the MDRS such that the negative impacts of this species on water turbidity, aquatic plant biomass and native fish abundances are reversed (McColl et al, 2014(McColl et al, , 2016.…”

Ecosystems worldwide are increasingly being invaded by multiple species, and the rate of biological invasion is accelerating, leading to more interactions among invasive species. One such interaction that has received little attention is the phenomenon of ‘serial replacement’ or ‘over-invasion’, where an established invasive species is supplanted by a second invasive species. Understanding this interaction is important as controlling the second species could inadvertently lead to an increase in the abundance of the first species. We used a hierarchical state-space model to analyse changes in annual abundances (commercial catch-per-unit-effort) of two invasive fish species, the tench (Tinca tinca) and the common carp (Cyprinus carpio), in the Murray-Darling River system (MDRS), Australia between 1954–2002. Tench were present at low abundances until the mid-1970s, after which they declined to the point of no commercial catch post-1989. The rapid decline in tench coincided with a significant increase in carp abundance, suggesting that carp may have driven the tench decline, consistent with findings from European studies that show substantial dietary overlap between these species and the disappearance of tench from ponds with intensive carp farming. While carp were present in the MDRS for the duration of the study, the rapid increase in carp abundance in the early 1970s coincided with the introduction of a specific genetic lineage – the “Boolarra strain” of carp. Our analysis of long-term changes in invasive fish species abundances provides compelling evidence of serial replacement of long-established tench by invading common carp triggered by the introduction of a novel carp strain.

Ecosystems worldwide are increasingly being invaded by multiple species, and the rate of biological invasion is accelerating, leading to more interactions among invasive species. One such interaction that has received little attention is the phenomenon of ‘serial replacement’ or ‘over-invasion’, where an established invasive species is supplanted by a second invasive species. Understanding this interaction is important as controlling the second species could inadvertently lead to an increase in the abundance of the first species. We used a hierarchical state-space model to analyse changes in annual abundances (commercial catch-per-unit-effort) of three invasive fish species, tench (Tinca tinca), common carp (Cyprinus carpio) and redfin perch (Perca fluviatilis), in the Murray-Darling River system (MDRS), Australia between 1954–2002. Tench were present at low abundances until the mid-1970 s, before declining to the point of no commercial catch post-1989. This rapid decline coincided with a significant increase in carp abundance, suggesting that carp may have driven the tench decline through habitat modification (particularly the destruction of aquatic plants), consistent with findings from European studies that show the disappearance of tench from ponds with intensive carp farming. Redfin perch populations, were inferred to be much less impacted by the invading carp population. While carp were present in the MDRS for the duration of the study, the rapid increase in carp abundance in the early 1970 s coincided with the introduction of a specific genetic lineage—the “Boolarra strain”. Our analysis provides compelling evidence of serial replacement of long-established tench by invading common carp triggered by the introduction of a novel carp strain.
