Exponential increase of signal crayfish in running waters in Sweden – due to illegal introductions?
Sweden has only one indigenous species of crayfish, the noble crayfish (Astacus astacus, Fabricius). There has been a steady decline of noble crayfish populations in Sweden since 1907, mainly due to the crayfish plague.

The impact of streetlights on an aquatic invasive species: artificial light at night alters signal crayfish behaviour [PDF]
Artificial light at night (ALAN) can significantly alter the behaviour, communication and orientation of animals, and will potentially interact with other stressors to affect biodiversity.

Environmental DNA‐based methods detect the invasion front of an advancing signal crayfish population
Aquatic invasive species, such as the signal crayfish (Pacifastacus leniusculus), present a major threat to freshwater ecosystems. However, these species can be challenging to detect in recently invaded habitats.

The impact of signal crayfish (Pacifastacus leniusculus) on the recruitment of salmonid fish in a headwater stream in Yorkshire, England [PDF]
Signal crayfish (Pacifastacus leniusculus) have become increasingly widespread in rivers in Great Britain since their introduction in the late 1970s, causing extensive losses of indigenous white-clawed crayfish and negative impacts on communities of ...

CRAYFISHERIES IN FINLAND, A SHORT OVERVIEW
Crayfish trapping and activities related to crayfishing have traditionally been lucrative businesses in rural Finland. The catch itself, varying in the 1990’s from 2 to 4 millions crayfish annually, is worth 4 to 8 millions euros.

Heavy metals effects on life traits of juveniles of Procambarus clarkii [PDF]
An incubation experiment of juvenile crayfish (Procambarus clarkii) following a three- level treatment design approach was performed to assess the effect of different heavy metal concentrations on their life history traits (lifespan, growth, moult and ...

Invasive crayfish impacts on native fish diet and growth vary with fish life stage [PDF]
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.
