The Baltic Sea is a brackish, semi-enclosed regional sea strongly affected by the combination of anthropogenic pressures including warming, eutrophication and deoxygenation. Along with past and current overfishing, fish community composition and population structures and the resulting trophic and behavioral interactions are rapidly changing, with drastic consequences including the collapse of many commercial fish stocks. ConserFish will study causes and consequences of current changes, and provide baseline data for the future assessment of spatial protection measures.
The first objective will be the continuation of genomic monitoring in Eastern Baltic Cod (EBC), to follow up on our past finding that markedly lower sizes are correlated with genomic changes and differences in genome structural variation, which would represent one of the first examples of fisheries induced evolution in a field setting. In order to compare the reproductive isolation between EBC and western Baltic cod (WBC), we will also monitor the spatial distribution of larvae and zooplankton prey, along with abiotic conditions.
Secondly, we will conduct a pilot study on food web structure and fish movement ecology within and outside of the Nature Conservation Area (NCA) 鈥淧omeranian Bay 鈥� R酶nne Bank鈥�. The focus will lie on dedicated food web sampling for later dietary tracer (stable isotopes, stomach content metabarcoding) analyses and food web modeling, and on the collection of habitat data to support the planned establishment of a receiver network in the NCA, linking individual behaviour with population level processes.

The work is embedded into two ongoing nationally funded projects, the DFG research training group 2501 鈥淭ranslational Evolutionary Research", project 鈥淔isheries Induced Evolution鈥� and the DAM-funded project "SpaCeParti", as well as the planned large-scale BfN project SCHUFI ("Schutzkonzepte zu Fischen und Fischerei鈥�)
