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.

Impacts of signal crayfish on stream fishes [PDF]

, 2013
Invasive species cause biodiversity and economic loss globally. Invasive crayfish have a wide range of effects as a result of their high densities and biomass, feeding at multiple trophic levels, aggressive competition for shelter and ecosystem ...

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

Data-poor stock assessment of Narrow-Clawed Crayfish (Pontastacus leptodactylus) in Keban Dam Lake (Türkiye) Using CMSY Method

Turkish Journal of Fisheries and Aquatic Sciences, 2023
In this study, as a data-poor fish stock assessment method CMSY was used to assess the current stock status of the Keban reservoir crayfish stock due to not having further data set for using the data-rich models. A total of 27 years catch data (from 1995

Prediction of Geometric Dimensions in 3D Printed Concrete: BP Neural Network Optimised by Enhanced Crayfish Algorithm

IET Collaborative Intelligent Manufacturing, Volume 8, Issue 1, January/December 2026.
We propose an enhanced crayfish optimisation algorithm (ECOA) and use ECOA to optimise the BP neural network (BPNN) to obtain a new prediction model ECOA‐BPNN for an accurate prediction of 3D printed concrete geometric dimensions. ABSTRACT 3D printed concrete technology has revolutionised construction methods by enabling the fabrication of complex ...

A Biologically Inspired Intelligent and Energy Efficient Route Optimization Clustering Algorithm for Internet of Vehicles (IoV)

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This work proposes COANET (crayfish optimization algorithm‐based route optimization for IoV Networks), which is an innovative bio‐inspired framework based on the crayfish optimization algorithm. COANET's core utilized the crayfish behaviours of foraging, competition and summer resort to allow the dynamic balancing of exploration and exploitation during

Evaluation of different dietary protein and energy levels on growth performance and body composition of narrow clawed crayfish (Astacus leptodactylus) [PDF]

, 2012
Nine practical diets containing increasing percentages of crude protein (CP) and energy (30%, 35%, 40% and 300kcal/100g, 370kcal/100g and 450kcal/100g) were fed to narrow clawed crayfish (mean individual weight=17±2.3 g) during an 8 week feeding trial ...
