Aquaculture

Teichlandschaft mit Teichen und Belüftern — View across fish ponds.

Aquaculture is the farming of aquatic organisms like fish, crustaceans, molluscs and aquatic plants in artificial systems, coastal and inland waters. Aquaculture involves the intervention in the rearing process to enhance production. In contrast to capture fisheries, the stock being cultivated is under individual or corporate ownership. The global demand for fish and seafood has been increasing rapidly throughout the last decade. Capture fisheries production, however, continuous to remain stable. Aquaculture is thus getting more and more important as substantial increases in global fish production can only be achieved by farming. At present, more than 50% of fish and seafood for human consumption are derived from aquaculture. Indeed, the expansion of aquaculture gave rise to several questions, e.g. in the fields of technology, ecology as well as in socioeconomics. With our research, we want to contribute in solving these questions making aquaculture sustainable.

Topics

Animal welfare in aquaculture systems

Animal welfare is of crucial importance for developing a modern and sustainable aquaculture. However, it is by far more difficult to define criteria for animal welfare in fish compared to common farm animals.

Economics of Fish Farms

Durchflussanlage zur Aufzucht von Forellen in der Türkei

A fish farm's economic efficiency is of crucial importance to persist in today's market. Which factors drive production costs? What are the key elements of economic success?

- description:
- abstract: European smelt (Osmerus eperlanus) is a key species in the estuaries of the major German rivers and the shallow coastal areas of the North Sea. Currently, the population of the species has declined considerably. The reasons for this are not fully understood. With our experience in aquaculture, we want to artificially propagate European smelt and raise it under controlled conditions. This shall allow us to carry out ecophysiological studies on the early life stages in order to investigate the possible causes for its decline in the wild.

- abstract: Pond farming areas provide a variety of services and more than mere fish production: fish farming ponds have positive effects on microclimate and regional water balance. They do not only serve as valuable habitats for many species, but also provide jobs and a space for recreation and tourism. Exploring possibilities on how this ecologically important cultural landscape with its high biodiversity can be protected is the main focus of the “TeichLausitz” project.
