Integratives Fischereimanagement, (speziell Angelfischerei)

 

We pursue a strongly integrative research program aimed at understanding the social, economic, biological, ecological and evolutionary dimensions of freshwater recreational fisheries. We consider recreational fisheries to constitute a prime example of a coupled social-ecological system. Many of our projects have inter- or even trans disciplinary components and blend the natural and the social sciences, with the aim of a better understanding of recreational fisheries as systems and to derive recommendations for sustainable management. In our natural scientific research questions we focus on understanding the biological impacts of recreational fisheries and other forms of fisheries. Within our social science research branch we study the human dimensions and the behaviour of anglers and the conflicts surrounding fish resource use. We also ask some basic fish ecological questions, focusing on the behavioural ecology of freshwater fishes. We aim at integration of social and natural science whenever possible to achieve a more holistic understanding of fisheries resource use.

Recreational fisheries as social-ecological systems

The cornerstone of our work is analyzing the interactions and feedbacks of anglers and fish stocks in freshwater landscapes. We conceptualize recreational fisheries as strongly coupled systems with non-linear feedbacks and cross-scale interactions. We particularly emphasize the human side of the complex interaction by developing empirical models of angler behaviour and integrating them with fish population models.

Recreational fisheries management

We develop interdisciplinary frameworks, principles and approaches to help national and international recreational fisheries move towards sustainability. Much of this work is synthetic based on world-wide experiences and published literature.

[ 2 ] Fisheries Ecology and Evolution

 

Fisheries-induced evolution

We are studying how recreational fisheries change the life-history, behaviour and physiology of exploited fish stocks through directional selection. We are using mathematical models and experimental studies models. Currently, we are particularly interested in understanding the relationship of behaviour, personality and vulnerability to fishing.

Catchability and catch rates in recreational fisheries

One of the key parameters in every fishery model is the catchability of a specific gear. Density-dependent catchability, for example, may lead to depensation and collapse of fisheries. We are studying questions of catchability and determinants of catch rates of recreational angling gear.

Understanding and managing of fish stocking

We conduct experiments to learn about the conditions under which stocking provides desirable benefits and when it produces no tangible effects and even negative outcomes. We use fisheries biological approaches, genetics and modelling to accomplish our goals.

Fish welfare and the ethics of fishing

We have been promoting a pragmatic view to fish welfare and have also helped re-analyse

whether fish feel pain. We study these questions to ask questions about the ethics of recreational fishing.
