Signal crayfish, Pacifastacus leniusculus, as a vector for Psorospermium haeckeli to noble crayfish, Astacus astacus

Aquaculture, 1996
Abstract As part of investigations of the ecological impact and transmission of the crayfish parasite Psorospermium haeckeli , a laboratory experiment was performed where noble crayfish, Astacus astacus , and signal crayfish, Pacifastacus leniusculus , from populations in which P.

Does the introduced signal crayfish occupy an equivalent trophic niche to the lost native noble crayfish in boreal lakes?

Biological Invasions, 2014
The introduced North-American signal crayfish (Pacifastacus leniusculus) has become widespread throughout Europe where it has often replaced the native noble crayfish (Astacus astacus). The impact of this replacement on ecosystem processes in boreal lakes is still largely unknown. We compared the trophic niches of these two crayfish species in 16 small

Numerous population crashes of wild signal crayfish (Pacifastacus leniusculus) in southern Finland

Freshwater Crayfish, 2014
The alien signal crayfish (Pacifastacus leniusculus) was introduced into Finland, and then more broadly in Europe, with the expectation that it would be a suitable substitute for the native crayfish that was eradicated by crayfish plague (Aphanomyces astaci) epidemics.

The Mycobiome of a Successful Freshwater Invader, the Signal Crayfish

2022
Fungi and fungal-like organisms are among the most damaging pathogens for freshwater crayfish and may cause significant losses of both aquacultured and wild crayfish populations. Furthermore, the most devastating effects in wild populations are caused by fungal and fungal-like pathogens transmitted by invasive crayfish species (ICS) to native crayfish ...

Stochastic Synchronization and Signal Rectification in the Crayfish Caudal Photoreceptor

AIP Conference Proceedings, 2003
The crayfish possesses two light‐sensitive neurons in its abdominal 6th ganglion (“caudal photoreceptors”, or CPRs). In addition to being light sensors, the CPRs are secondary neurons in a mechanosensory pathway. These sensory mechanisms, mechanosensitivity and light sensitivity, interact with one another.

Interactions between two invasive crayfish species, the signal crayfish (Pacifastacus leniusculus) and the spiny cheek crayfish (Orconectes limosus) : outdoor experiment and laboratory study

2010
Crayfish are key ecosystem engineers and important components of freshwater food webs, both in terms of biomass and ecosystem functioning, due to their large body size, long life span, omnivorous feeding habit, and aggressiveness. Individual effects of non-indigenous crayfish species on native crayfish fauna are well documented as well as their impacts

PHARMACOKINETICS OF CEFTAZIDIME IN SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS) FOLLOWING A SINGLE DOSE

Journal of Zoo and Wildlife Medicine
Crustaceans are housed in zoos and aquariums and have also gained importance in the private sector and food industry. Shell lesions are common and often attributed to bacterial infections. However, few controlled studies have been performed evaluating antibiotics in crustaceans.

Ecological characteristics of invasive signal crayfish (Pacifastacus leniusculus) in Croatia

2010
Non-indigenous crayfish species (NICS), namely signal crayfish (Pacifastacus leniusculus) has been recorded in the Croatian part of the Mura River in 2008. . Its presence in the Mura River is probably a consequence of its spread from upstream segments of the river in Slovenia and Austria.
