Herring recruitment

To ensure an sustainable management of fish resources, natural mortality of a species' offspring (recruits) has to be incorporated into stock assessment methods.In the Data Collection Framework the Rügen Herring Larvae Survey monitors herring recruitment and with the annual recruitment index provides an important forecast instrument for stock dynamics of Western Baltic herring. Additionally, the survey represents an essential base line to investigate the drivers and stressors of natural mortality reflected in the recruitment index every year.

Coastal use and climate change (SpaCePartiE)

Subproject 5 in SpaCeParti aims to investigate the spatial dynamics of herring spawning and its effects on recruitment using modern approaches from population genetics (GEOMAR) and otolith chemistry (Thünen). The analyzes focus on identifying population genetics of consecutive spawning cohorts, determining homing behavior and spawning locations of seasonally earlier or later emerging spawning components. In addition, the contribution of different spawning areas to the dynamics of adult populations is quantified. The results of the spatial patterns in the herring spawning process will be ...

Adaptation of the Western Baltic Coastal Fishery to Climate Change (balt_ADAPT)

The cumulative impacts of climate change, together with the prevailing fishing pressure, pose a threat to the coastal fisheries resources of the Western Baltic Sea.

BONUS Project INSPIRE

The aim of INSPIRE is to substantially improve knowledge for a sustainable utilization of commercial fish species in the Baltic Sea. Fish species such as herring, sprat, cod and flounder are also ecological key species in the ocean's food web. Present knowledge gaps exist at mechanisms of spatial distribution of fish life stages, on the effect of climate change and exploitation on ecosystem structures and functions including the perception of these stressors in current stock assessments.

Spawning grounds under pressure (HERRING)

Coastal areas are important spawning and nursery habitats for herring while at the same time experiencing increased pressure from human activities. The management of these areas has to balance many claims and economic interests, so that their role as crucial prerequisites for the development of fish populations is often inadequately included into holistic management strategies.
