Scope for activity in the crayfish Pacifastacus leniusculus
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1981The scope for activity of the crayfish Pacifastacus leniusculus was determined between 5 and 30 degrees C (incipient lethal of 33 degrees C). Standard oxygen consumption rate (VO2) ws low (e.g., 17 ml x kg-1 x h-1 at 20 degrees C); and it increased with temperature over the entire range (Q10 = 2.09 for 5-25 degrees C).

A Pacifastacus leniusculus serine protease interacts with WSSV
Fish & Shellfish Immunology, 2017Serine proteases are involved in many critical physiological processes including virus spread and replication. In the present study, we identified a new clip-domain serine protease (PlcSP) in the crayfish Pacifastacus leniusculus hemocytes, which can interact with the White Spot Syndrome Virus (WSSV) envelope protein VP28.

Sterol requirement of cultured juvenile crayfish, Pacifastacus leniusculus
Aquaculture, 1985Abstract Changes in the sterol composition of an extruded diet revealed that juvenile Pacifastacus leniusculus requires at least 0.4% (dry weight) of dietary sterols for survival. A mixture of plant-derived sterols (phytosterols) is as effective as an equal amount of cholesterol in the partial satisfaction of the requirement. The experimental diet

Characterization of a cold-active transglutaminase from a crayfish, Pacifastacus leniusculus
Fish & Shellfish Immunology, 2018Transglutaminase (TGase) from signal crayfish (Pacifastacus leniusculus) and its activity at low temperatures was studied. TGase is an abundant protein in the hematopoietic (HPT) cells and this tissue was used for TGase enzyme preparation. The optimal temperature and pH for the activity of crayfish TGase were determined. We found that TGase activity at

State-dependent responses of two motor systems in the crayfish, Pacifastacus leniusculus
Journal of Comparative Physiology A, 1994The expression of both swimmeret and postural motor patterns in crayfish (Pacifastacus leniusculus) were affected by stimulation of a second root of a thoracic ganglion. The response of the swimmeret system depended on the state of the postural system. In most cases, the response of the swimmeret system outlasted the stimulus. Stimulation of a thoracic

Journal of Invertebrate Pathology, 2009
Aeromonas spp. are characteristic bacteria of freshwaters and many of them can be components of the bacterial flora of aquatic animals and may become pathogens on animals including humans. In this study Aeromonas hydrophila was isolated from the freshwater crayfish, Pacifastacus leniusculus, and was found to be a highly pathogenic bacterium among many ...

Numerous population crashes of wild signal crayfish (Pacifastacus leniusculus) in southern Finland
Freshwater Crayfish, 2014The 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.
