A suitable temperature regime in artificial incubation of crayfish eggs is crucial for successful application in aquaculture production and conservation projects. We studied the effect of different extended cold periods (CP: 10, 24 and 38 days at 7.5 ± 0.

article i nfo Apparently healthy wild noble crayfish (Astacus astacus) sampled from Lake Mikitanjarvi, Kainuu, Finland in 2009 and 2010 were discovered to be PCR-positive for Aphanomyces astaci. Detection prevalence was lower in 2009 than in 2010. Despite the detected sublethal infection, the Lake Mikitanjarvi population has been pro- ductive and is ...

Phylogeography of noble crayfish (
Summary Reconstructing the phylogeographic history of a species can aid in defining areas of conservation priority. For freshwater species, historical river structure plays a significant role in explaining genetic differentiation and population structure.

The study of bacteria on artificially incubated noble crayfish eggs
Inland Water Biology, 2011Data on the abundance of heterotrophic bacteria on the surface of artificially incubated noble crayfish (Astacus astacus L.) eggs are presented. The highest abundance of heterotrophic bacteria was observed on crayfish juveniles (stage 1). The abundance of bacteria in the water of the incubator’s system was found to be considerably lower than that on ...

Noble crayfish and narrow-clawed crayfish hybridisation experiment in natural habitat
2013Mixed populations of noble (Astacus astacus) and narrow-clawed crayfish (Astacus leptodactylus) can be found across Europe, but the existence of their hybrids has not yet been confirmed. Up till now, hybrids between the two species were obtained in laboratory conditions, however juveniles did not survive.

Recent findings point to the existence of immune memory in invertebrates. Some species show an improved immune response to pathogen challenge after previous nonlethal exposures to the pathogen or its analogues. This mechanism, although little studied in freshwater crayfish, could have significant applications in aquaculture.

Predation on larvae of the noble crayfish, Astacus astacus L.
Aquaculture, 1990Abstract The predation by dragonfly larvae ( Aeschna grandis ) and adult female crayfish on second-stage young of the noble crayfish, Astacus astacus , was studied in aquarium experiments. Combinations of crayfish young with and without adult female crayfish, with and without shelter were made in 4×4 set-ups with dragonfly larvae and 4×2 without ...
