Molecular Fish Physiology
Comparative and evolutionary genomics analyses enable improved genome assemblies to support the sustainable development of commercial percid fish species, aiming at improved reproductive management, breeding and feeding technology (DFG).

Our research focuses on the physiological mechanisms involved in the regulation of reproduction, nutrition and the immune system as essential basis for the species-appropriate rearing in aquaculture. The molecular mechanisms (including genetics) and the biotic and abiotic interactions provide the incentives for the optimization of current aquaculture practice and thereby support the sustainable development (species-specific needs/animal welfare, technological R&D, diversification) of fish farming. Combining chemical, molecular, histological and bioinformatic methods, we aim at contributing for a better understanding of the biology and diversity of fish. Providing a knowledge base for consumers and experts, we outline important topics in aquaculture on the internet platform Aquakulturinfo.

The arapaima is heavily hunted for its meat and is now threatened by extinction. Establishing the technology to reproduce and grow fish in aquaculture will reduce the fishing pressure and support farming in rural, remote areas of South America. | Photo: Sven Würtz / IGB
Functional feed improve stress resistance and health. Establishing native probiotics in finfish provide thus an alternative to pharmaceutical approaches improving overall aquaculture sustainability. | Photo: Konrad Wanka / IGB
