Signal crayfish as vectors in crayfish plague in Britain

Aquaculture, 1990
Abstract An outbreak of crayfish plague (caused by the fungus Aphanomyces astaci) is described in white-clawed crayfish, Austopotamobius pallipes, in enclosed pond culture in an area of England from which no disease outbreaks have yet been reported.

Visceral Afferent Signals in the Crayfish Stomatogastric Ganglion

Journal of Experimental Biology, 1966
ABSTRACT The crayfish stomatogastric ganglion (SG) contains about twenty-five neurone somata; it supplies motor innervation for the anterior gut, and receives afferent input from mechanoreceptors associated with the stomach. Its proximal branches respond to normal stomach contractions with a complex, patterned, centrally directed ...

Brain Electrical Signals in Unrestrained Crayfish

2002
The electrical activity from the brain of vertebrates and some mollusks (octopus and cuttlefish; Bullock 1984) is dominated by slow components in the range 0 to 30 Hz and fast events such as spikes are seen by special effort. In contrast, electrical activity from the brain of several invertebrates such as crayfish, earthorm, slug and grasshopper, is ...

Properties of glutaminase of crayfish CNS: implications for axon–glia signaling

Neuroscience, 2002
Glutaminase of crayfish axons is believed to participate in recycling of axon-glia signaling agent(s). We measured the activity and properties of glutaminase in crude homogenates of crayfish CNS, using ion exchange chromatography to separate radiolabeled product from substrate.

The vulnerability of juvenile signal crayfish to perch and eel predation

Freshwater Biology, 1995
SUMMARY1. We conducted laboratory experiments to determine how juvenile signal crayfish (Pacifastacus leniusculus) responded to two predators with different foraging behaviours (European eel Anguilla anguilla and European perch Perca fluviatilis), and whether these responses affected their vulnerability.2.

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 ...
