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.

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.

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 ...

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

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
