“…Furthermore, under certain circumstances each omnivorous fish and crayfish might harm heterospecifics (Neveu, 2001); fish might harm vulnerable crayfish at molting, and the nocturnal crayfish might harm diurnal fish at night when the fish are less active. Thus, fish-crayfish relationships appear to be complex; it involves both competition and predation (Dorn and Mittelbach, 1999;Reynolds, 2011) and it can be reversed, depending on relative size (Keller and Moore, 2000).…”

“…In rivers, signal crayfish may reduce the growth and abundance of small benthic fishes, through interspecific competition and predation (Guan and Wiles 1997;Light 2005), and out-compete fish for refugia (Griffiths et al 2004); yet other research has reported no effects of invasive crayfish on juvenile fish survival (Stenroth and Nyström 2003). However, there have been relatively few attempts to assess the specific impacts that signal crayfish may have on larger fish species of ecological and recreational importance (Reynolds 2011;Ruokonen et al 2012; but see Bašić et al 2015). Understanding the full-range of crayfish-fish interactions, and both the individual-and population-level consequences are essential if fish populations are to be managed successfully.…”

Invasive crayfish impacts on native fish diet and growth vary with fish life stage

Assessing the impacts of invasive organisms is a major challenge in ecology. Some widespread invasive species such as crayfish are potential competitors and reciprocal predators of ecologically and recreationally important native fish species. Here, we examine the effects of signal crayfish (Pacifastacus leniusculus) on the growth, diet, and trophic position of the chub (Squalius cephalus) in four rivers in Britain. Growth rates of 0? chub were typically lower in sympatric populations with signal crayfish compared with allopatric populations, and this effect could be traced through to 2? chub in one river. However, growth rates of older chub (5? to 6?) were typically higher in the presence of crayfish. Sympatry with crayfish resulted in lower chub length-at-age and mass-at-age in half of the rivers sampled, with no change detected in the other rivers. Stable isotope analyses (d 13 C and d 15 N) revealed that both chub and crayfish were omnivorous, feeding at multiple trophic levels and occupying similar trophic positions. We found some evidence that chub trophic position was greater at invaded sites on one river, with no difference detected on a second river. Mixing models suggested crayfish were important food items for both small and large chub at invaded sites. This study provides evidence that invasive species can have both positive and negative effects on different life stages of a native species, with the net impact likely to depend on responses at the population level.

“…These include changes in species composition and abundance of aquatic plants (Gherardi and Lazzara, 2006;Gherardi and Acquistapace, 2007), insects, molluscs, as well as eggs and developmental stages of amphibians and fish (Cruz et al, 2008;Reynolds, 2011). Its burrowing activity damages embankments and dams and can result in water leakage (Souty-Grosset et al, 2016).…”

-An increasing number of non-indigenous crayfish species (NICS) of apparently pet trade origin have become established particularly in Europe. Especially alarming are recent confirmation of two distantly separated marbled crayfish Procambarus fallax f. virginalis populations in Ukraine and indications of more North American cambarids present in the local pet market. The present study aimed to investigate crayfish species availability within the Ukrainian pet trade together with the climate match and risk they represent to the freshwater ecosystems generally and indigenous crayfish species in particular. Altogether, 15 NICS belonging to all three crayfish families were detected. Considering their origin, availability, probability of establishment, invasiveness and further aspects, marbled crayfish and red swamp crayfish Procambarus clarkii appear to be potentially the most troubling. Available information obtained from the pet trade in ornamental crayfish as a whole demonstrates that the broad availability of NICS most probably overlaps the vast majority of European indigenous crayfish species distribution, including the endemic thick-clawed crayfish Astacus pachypus, which occupies only a limited area that is situated critically close to established marbled crayfish populations. Negative effects of NICS on freshwater ecosystems as a whole can be also expected.
