Scope for activity in the crayfish Pacifastacus leniusculus

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1981
The 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, 2017
Serine 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.

Predicting invasive signal crayfish (Pacifastacus leniusculus) spread using a traditional survey and river network simulation

Rivers Research and Applications: an international journal devoted to river research and management, 2022
Rivers are among the most vulnerable ecosystems to biological invasions. After introduction, predicting the timing and magnitude of population growth and range expansion is critical to decision making on where management tactics will be most efficient ...

Sterol requirement of cultured juvenile crayfish, Pacifastacus leniusculus

Aquaculture, 1985
Abstract 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

Reproductive Dynamics of Pacifastacus leniusculus (Decapoda, Astacidae) in the Clitunno River: A Case Study of the Southernmost Population in Italy

Freshwater Crayfish
In this study, the reproduction of the southernmost Italian population of the invasive Pacifastacus leniusculus (Dana, 1852) was analyzed. The species was recorded for the first time in the Clitunno River in 2020, an eradication plan started in June ...

Genome skimming supports two new crayfish species from the genus Pacifastacus Bott, 1950 (Decapoda: Astacidae).

Zootaxa
Recent phylogenetic analyses have suggested that the Signal Crayfish, Pacifastacus leniusculus (Dana, 1852), contains two highly distinct lineages that merit recognition as species.

Catabolic pathways of carbohydrate in the intermolt crayfish, Pacifastacus leniu sculus

Comparative Biochemistry and Physiology, 1965
Abstract 1. 1. The radiorespirometric method was used to study the catabolic pathways of carbohydrates in the intact intermolt crayfish, Pacifastacu leniusculus . 2. 2. The terminal respiratory mechanism was studied using specifically labeled acetate and dl -glutamate.

The role of mitophagy during hematopoiesis in an invertebrate, Pacifastacus leniusculus.

Journal of Immunology
Freshwater crayfish as most aquatic crustaceans live for up to 20-30 years on the bottom of lakes and rivers, constantly exposed to millions of microorganisms. Consequently, they must have an effective immune system to combat and eliminate pathogens. The
