Аge structure and fecundity of the noble crayfish populations in abandoned quarries

Proceedings of the National Academy of Sciences of Belarus, Biological Series, 2022
The population of noble crayfish (Astacus astacus) was researched in quarries of an old brick plant in Molodechno district of Minsk region. Rare disappearing noble crayfish was found in 10 closed quarries. The presence of crayfish in closed quarries that are not connected with watercourses indicates that these populations were created by man.

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.

Boldness as a consistent personality trait in the noble crayfish, Astacus astacus

acta ethologica, 2010
Consistent individual differences in behavioural responses to perceived predation risk may have extensive ecological and evolutionary implications. We studied the repeatability of boldness across time and its relation to resource holding potential in the noble crayfish, Astacus astacus L., using predator-naive immature individuals.

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 ...

Noble Crayfish Aquaculture: Embryonic Development and Juvenile Performance

, 2021
Freshwater crayfish play an important role in freshwater ecosystems and represent a highly appreciated food item. The European crayfish fauna comprises five indigenous species and noble crayfish Astacus astacus (L. 1758) is the only species native to Northern Germany.

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.

Unifying waste conversion and endangered species conservation in polyculture production with Lake Constance whitefish and noble crayfish

Aquaculture Reports
Bioconversion is a sustainable method to recycle nutrient-rich aquaculture waste. This study explored waste bioconversion in the context of species conservation through a polyculture system involving the endangered Lake Constance whitefish (Coregonus ...
