Application of geometric morphometrics in comparative analyses of noble crayfish and narrow- clawed crayfish and their possible hybrids

2013
Geometric morphometrics (GM) has been widely applied in studying different organisms, and it proved itself as a powerful method in discriminating different stocks, populations or groups of organisms. Up till now, in the freshwater crayfish research, GM has been used only in the white-clawed crayfish (Austropotamobius pallipes). The aim of this research

Is it possible to detect narrow-clawed and noble crayfish probable hybrids using morphometric MDA? [PDF]

, 2012
Hybrids between Astacus leptodactylus and Astacus astacus have been obtained in laboratory conditions. Even though their occurrence within natural habitats has been sporadically mentioned, to our knowledge, no detailed study has been conducted so far to confi rm their existence. In Croatia both A. astacus and A. leptodactylus are native, with the latter

Growth pattern and body weight-length relationship of narrow clawed crayfish, Astacus leptoductylus

2014
In order to investigation of growth pattern and body weight-length relationship of narrow clawed crayfish, Astacus leptodactylus in different stages of its life, approximately 10000 newborn crayfish were released in earthen pond. This pond had the similar condition to their habitat. Sampling was done during four stages of their life, under 2 months and

Influence of Eyestalk Ablation and Temperature on Molting and Mortality of Narrow-clawed Crayfish (Astacus leptodactylus)

2014
In this study, two experiments were conducted to investigate the effects of eyestalk ablation and temperature on molting and mortality of narrow-clawed crayfish (Astacus leptodactylus) in three replicates. In experiment 1, the percentage of molting in ablated crayfish was significantly higher than the percentage of non-ablated crayfish in control group
