Introduction
Working on developing new guidance devices to assist fish on downstream migration through regulated rivers. The project is part of the RIBES (River flow regulation, fish BEhaviour and Status) and funded by the European Training Network.

Article
Animals frequently engage in mutual displays that may allow or at least help decisions about the outcome of agonistic encounters with mutual benefit to the opponents. In fish these often involve lateral displays, with previous studies finding evidence of population-level lateralization with a marked preference for showing the right side and using t...

In traditional medicine marine extracts are extensively used as therapies for diabetes. With the increasing rate of incidence of type 2 diabetes mellitus and rising cost of treatments, we investigated the anti-diabetic properties of extracts of common edible seaweeds in Europe including their ability to inhibit alpha-glucosidase and dipeptidyl pept...
Article
Full-text available
Populations of the European eel (Anguilla anguilla), a critically endangered species, have been severely impacted by migration barriers, as losses due to turbine-induced mortality can be substantial. To prevent eels from entering turbines, effective guidance systems are needed to redirect downstream-migrating eels towards safer alternative passage...
Article

Multiple anthropogenic forces have pushed river ecosystems into undesirable states with no clear understanding of how they should be best managed. The advancement of riverine fish habitat models intended to provide management insights has slowed. Investigations into theoretical and empirical gaps to define habitat more comprehensively across differ...
Chapter
Abstract The lack of free-flowing rivers worldwide is one of the factors driving the decline of freshwater migratory fish populations, as dams obstruct migratory pathways. To restore river connectivity, downstream solutions are necessary, in addition to upstream efforts. Fish tend to follow bulk flow as they migrate downstream, and unless enough fl...

The challenge of managing aquatic connectivity in a changing climate is exacerbated in the presence of additional anthropogenic stressors, social factors, and economic drivers. Here we discuss these issues in the context of structural and functional connectivity for aquatic biodiversity, specifically fish, in both the freshwater and marine realms....
Conference Paper
When fish migrate downstream, they follow bulk flow and unless enough flow is redirected towards a bypass, they need guidance to pass the dam. Guidance relying on behavioural responses by fish are generally less effective but less expensive than physical guidance structures, and hence there is an interest in finding more effective behavioural guida...
