Monitoring of noble, signal and narrow-clawed crayfish using environmental DNA from freshwater samples.

open access: yesPLoS ONE, 2017
For several hundred years freshwater crayfish (Crustacea-Decapoda-Astacidea) have played an important ecological, cultural and culinary role in Scandinavia.

Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry

open access: yesFish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.
ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.

Preliminary multispecies test of a model for non-lethal estimation of metabolic activity in freshwater crayfish

open access: yesActa Biologica Slovenica, 2012

ANNUAL ACTIVITY OF THE NOBLE CRAYFISH (ASTACUS ASTACUS) IN THE ORLJAVA RIVER (CROATIA) [PDF]

open access: yesBulletin Français de la Pêche et de la Pisciculture, 2006
We studied the annual activity of the noble crayfish (Astacus astacus) at three sites along the Orljava River, in the continental part of Croatia, between August 2003 and September 2004. Each site represented the typical characteristics of the upper, middle and lower section of the river (5, 30 and 50 km from the spring, respectively).

Research on the Application of Green Ecological Additive Combinations During the Breeding Period of Redclaw Crayfish

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The three key processes in the breeding of redclaw crayfish are nutrient enhancement by parents, catching and hatching of egg‐holding crayfish and maintaining a feed supply for juveniles. An appropriate combination of green ecological additives is beneficial for improving the production efficiencies of the three key processes.

Drivers of the range expansion of the European catfish (Silurus glanis) within its native distribution

open access: yesJournal of Fish Biology, Volume 107, Issue 3, Page 1030-1044, September 2025.
Abstract The European catfish Silurus glanis L. continues to spread as an invasive species in Europe. Meanwhile, increasing abundance and range expansions are also suspected within its native distribution. The objective of this study was to characterize the feeding, growth and abundance of S.

Prioritising Non‐Native Crayfish Species for Management in the Rhine‐Main Observatory Using the Dispersal‐Origin‐Status‐Impact (DOSI) Scheme

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 7, July 2025.
ABSTRACT Managing non‐native species remains a critical challenge in biodiversity conservation, highlighting the need for effective prioritisation frameworks that integrate ecological, economic and policy considerations. Given that biological invasions are a population‐level rather than a species‐level phenomenon, more nuanced assessment schemes are ...

Study of Phenotypic Correlations between Morphologic Characters and Body Parameters at River Male Lobsters (Astacus Fluviatilis)

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The body measurements was made on 20 males of river lobster (Astacus fluviatilis or Astacus astacus). The lobsters on witch the study was made had an average total length of body of 12.72 cm ±0.19 cm (formed from: 6.07±0.10cm the length of cefalothorax ...
