Development and characterization of novel tetranucleotide microsatellite markers in the noble crayfish (Astacus astacus) suitable for highly multiplexing and for detecting hybrids between the noble crayfish and narrow-clawed crayfish (A. leptodactylus)

Aquaculture, 2017
Abstract 48 novel tetranucleotide microsatellite loci were developed for the noble crayfish ( Astacus astacus ) using Illumina MiSeq next generation sequencing technology. It was demonstrated that 25 loci were polymorphic and 19 loci could be co-amplified in a single multiplex polymerase chain reaction (PCR) assay and genotyped as a single panel on ...

Ultrastructure of egg activation and cortical reaction in the noble crayfish Astacus astacus

Micron, 2015
Morphological changes in the gamete of female noble crayfish at four developmental stages were studied. Mature ovarian oocytes are enclosed by the first envelope that consists of two layers. Numerous pores are visible on the surface of the outer layer of this envelope and the inner layer contains bottlebrush-shaped objects.

Egg development and lifecycle timing in the noble crayfish (Astacus astacus)

Aquaculture, 1987
Abstract Egg development time in Astacus astacus was strongly influenced by temperature. Five batches of eggs were subjected to different temperature regimes after approximately 600 degree days and, by increasing the temperature, the total number of degree days to hatching was reduced from 1900 to 1300.

GENETIC DIVERSITY AND POPULATION STRUCTURE OF THE NOBLE CRAYFISH IN CROATIA

2021
The noble crayfish Astacus astacus L. is a native European freshwater species whose contemporary distribution and genetics have been shaped by geo-climatic events (i.e. Pleistocene glaciations) and anthropogenic impacts (i.e. translocations, pollution, invasive species).

Distribution and epidemiology of genotypes of the crayfish plague agent Aphanomyces astaci from noble crayfish Astacus astacus in Finland

Diseases of Aquatic Organisms, 2013
The crayfish plague agent Aphanomyces astaci was isolated from 69 noble crayfish Astacus astacus samples in Finland between 1996 and 2006. All isolates were genotyped using randomly amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR).

Seasonal changes of the hepatosomatic indices in the noble crayfish (Astacus astacus) and the stone crayfish (Austropotamobius torrentium)

2004
A comparative study was conducted on two autochthon species of Astacidae in Croatia, the noble crayfish, Astacus astacus (Linne, 1758) and the stone crayfish, Austropotamobius torrentium (Schrank, 1803). Hepatosomatic indices (wet and dry hepatosomatic index) and hepatopancreas moisture content (HM) are considered useful to describe the physiological ...
