Distribution and dispersal of two invasive crayfish species in the Drava River basin, Croatia [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
The aim of this work is to explore the current distribution and dispersal rates of two nonindigenous crayfish species (NICS) recorded in Croatia: the signal crayfish (Pacifastacus leniusculus) and spiny-cheek crayfish(Orconectes limosus).

Recent changes in distribution pattern of freshwater crayfish in Croatia − threats and perspectives

Knowledge and Management of Aquatic Ecosystems, 2018
Analysis of Croatian freshwater crayfish populations, aiming to gather new distributional data and complement previous surveys (2005–2011), was performed during 2014–2016, within the frame of Natura 2000 Integration Project.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Rapid assessment of population dynamics and monitoring methods for invasive narrow clawed crayfish Pontastacus leptodactylus in a freshwater reservoir

Knowledge and Management of Aquatic Ecosystems
Narrow-clawed crayfish (Pontastacus leptodactylus) are a data deficient invasive non-native species in the UK. Boshaw Whams (West Yorkshire, UK) contains the only known population of narrow-clawed crayfish in Yorkshire.

Observations of crayfish plague infections in commercially important narrow-clawed crayfish populations in Turkey

Knowledge and Management of Aquatic Ecosystems, 2018
We studied the presence of possible Aphanomyces astaci infections in eight Turkish narrow-clawed crayfish (Astacus leptodactylus) populations by analyzing the prevalence and genotypes of the disease agent A. astaci. The qPCR analyses revealed A.

Interactive effects between burrowing crayfish and flow conditions increase riverbank erosion: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Biological and geomorphic effects have been treated independently in fluvial geomorphology. Flume experiments with burrowing crayfish show that interactions between these drivers do more geomorphic work than the sum of their maximum independent parts combined, meaning total biogeomorphic effects to rivers are likely underestimated.

Meat Yield and the Length–Weight Relationships of the Narrow‐Clawed Crayfish, Pontastacus leptodactylus (Eschscholtz, 1823)

Momona Ethiopian Journal of Science, 2023
The present study investigated the length-weight relationships and meat yield of narrow-clawed crayfish, Pontastacus leptodactylus (Eschscholtz, 1823), in Kocahıdır Irrigation Reservoir. Between July 2015 and June 2016, a total of 653 individuals (255 females and 398 males) were sampled, and their carapace lengths (CL), total lengths (TL), and total ...

Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

Advanced Science, Volume 13, Issue 15, 13 March 2026.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Crayfish distribution updating in central Italy [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Introductions of non-indigenous crayfish have received great attention from biologists and policy makers during the last decade. Purposes of this study are to update the knowledge about the crayfish distribution in Latium (central Italy), and to show how
