Abstract

The Chinese mitten crab (Eriocheir sinensis), an invasive species causing significant ecological damage in Belgium, requires efficient management tools to mitigate its impact on the environment. This project explores the use of imaging sonar technology as an innovative solution to detect and count mitten crabs in turbid aquatic environments. Initial testing in a controlled flume environment simulating real river conditions will assess the sensor's accuracy, followed by field trials in Flemish waterways. If successful, this method will enhance decision-making for trap placements and support sustainable management strategies. It will also enable scientists to study population dynamics and the spread of this invasive species more effectively.

Abstract

The impact of invasive species on ecosystems can cause habitat alteration or even habitat loss. This could ultimately lead to fundamental effects on ecosystem functioning. This project is focused on the case of the Chinese mitten crab (CMC). This is a new species and the only freshwater crab species in Flanders. Being the largest representative of the macroinvertebrates, it probably takes a prominent role in the processing of organic matter. This could have a profound effect on nutrient cycling and water quality in general. Through bioturbation, burrowing behaviour and their destructive impact on macrophytes, the CMC potentially impacts also the stability of river ecosystems, which may lead to enhanced erodibility. By investigating these different effects, this project will give fundamental insight in the impact of freshwater crab species on aquatic habitats along the river continuum.
