Post-mating spermatophore storage strategies in two species of crayfish: implications for broodstock management

Animal, 2018
Female crayfish stores male gametes after mating until the beginning of egg laying and fertilization. The aim of the present study was to investigate the duration of post-mating spermatophore storage as well as the timing and temperature of spawning in ...

Exponential increase of signal crayfish in running waters in Sweden – due to illegal introductions?

Knowledge and Management of Aquatic Ecosystems, 2011
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.

Hungary: a European hotspot of non-native crayfish biodiversity

Knowledge and Management of Aquatic Ecosystems, 2020
There is a long history of crayfish introductions in Europe and numbers keep increasing. In Hungary, spiny-cheek crayfish Faxonius limosus, signal crayfish Pacifastacus leniusculus, red swamp crayfish Procambarus clarkii, marbled crayfish P.

Sleep in invertebrates crayfish [PDF]

Frontiers in Bioscience, 2012
Although sleep is a very conspicuous behavior in all animals that we are frequently in contact with and possibly in many others, its scientific study was for many years restricted to very few of them. However, since the end of the XX century there have been studies about sleep in several animals and currently many of them attempt to found, first, if ...

THE EFFECT OF THE LARGE-SCALE INTRODUCTION OF SIGNAL CRAYFISH ON THE SPREAD OF CRAYFISH PLAGUE IN SWEDEN

Knowledge and Management of Aquatic Ecosystems, 2006
Since 1907, coinciding with the arrival of the crayfish plague, the noble crayfish (Astacus astacus) has steadily declined in Sweden. To substitute the noble crayfish fishery lost, mainly due to the plague, and since the species is highly susceptible to ...

Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology [PDF]

NeoBiota
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused on the NCE of predator-induced stress from one native

Crayfish epidemics

Parasitology, 1956
Epidemics in English crayfish, Astacus pallipes, were found to be due to micro-sporidia and yeasts similar to, if not identical with, those causing diseases in another Crustacean, namely, Gammarus pulex, in many parts of England.
