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

The signal crayfish is vulnerable to both the As and the PsI-isolates of the crayfish plague

Knowledge and Management of Aquatic Ecosystems, 2014
The carrier status and possible elevated tolerance of the signal crayfish (Pacifastacus leniusculus) against the crayfish plague disease agent (Aphanomyces astaci) has been speculated for several decades.

UTILIZATION OF WATER CRESS (NASTURTIUM OFFICINALE L.) IN NOBLE CRAYFISH (ASTACUS ASTACUS) FEEDING [PDF]

Bulletin Français de la Pêche et de la Pisciculture, 2006
Juvenile Astacus astacus (initial b.w.: 0.98 ± 0.06 g) were cultured (30 crayfish/m2) in 200l tanks for 69 days. The experimental design was composed of three treatments as follows: control diet (C) (crude protein: 28.4% of the total dried matter, “DM”; ether extract: 6.22% DM), water cress (W) (crude protein: 20.7% DM; ether extract: 1.9% DM) and ...

Aphanomyces astaci PsI-genotype isolates from different Finnish signal crayfish stocks show variation in their virulence but still kill fast

Knowledge and Management of Aquatic Ecosystems, 2013
We detected significant virulence differences among five tested (PsI-Puujärvi, PsI-Pyhäjärvi, PsI-Kukkia, PsI-Saimaa I and PsI-Saimaa II) PsI-genotype crayfish plague (Aphanomyces astaci) isolates against lake Mikitänjärvi noble ...

COMPARISON AMONG PRE-GELATINIZED STARCHES OF DIFFERENT BOTANICAL ORIGINS USED IN NOBLE CRAYFISH ASTACUS ASTACUS DIETS

Knowledge and Management of Aquatic Ecosystems, 2006
The objective of the present experiment was to compare the biological value and the binding functionality of four pre-gelatinized starches (wheat, diet 1; waxy maize, diet 2; maize, diet 3 and potato, diet 4) used in crayfish diets.
