Investigating the factors regulating fish condition is crucial in ecology and management of exploited populations. The body cod ( Gadus morhua ) Baltic Sea has dramatically decreased during past two decades, with large implications for fishery relying on this resource. Here, we statistically investigated potential drivers 40 years using newly compiled fishery-independent biological data hydrological observations. We evidenced a combination different operating before after ecological regime...
Abstract Theory behind ecosystem-based management (EBM) and fisheries (EBFM) is now well developed. However, the implementation of EBFM exemplified by in Europe still largely based on single-species assessments ignores wider ecosystem context impact. The reason for lack or slow EBM specifically a coherent strategy. Such strategy offered recently developed integrated (IEAs), formal synthesis tool to quantitatively analyse information relevant natural socio-economic factors, relation specified...
Natural resource management requires approaches to understand and handle sources of uncertainty in future responses complex systems human activities. Here we present one such approach, the "biological ensemble modeling approach," using Eastern Baltic cod (Gadus morhua callarias) as an example. The core approach is expose models with different ecological assumptions climate forcing, multiple realizations each scenario. We simulated long-term response fishing change seven ranging from...
Abstract Five decades of stomach content data allowed insight into the development consumption, diet composition, and resulting somatic growth Gadus morhua (Atlantic cod) in eastern Baltic Sea. We show a recent reversal feeding level over body length. Present levels small cod indicate severe limitation increased starvation-related mortality. For young cod, low rate high mortality are manifested through reduction size-at-age. The likely result decrease benthic prey abundance due to hypoxic...
Abstract Improving the health of coastal and open sea marine ecosystems represents a substantial challenge for sustainable resource management, since it requires balancing human benefits impacts on ocean. This is often exacerbated by incomplete knowledge lack tools that measure ocean ecosystem in way allows consistent monitoring progress towards predefined management targets. The such limits capabilities to enact enforce effective governance. We introduce Baltic Health Index (BHI) as...
Individual behaviour of Atlantic cod Gadus morhua in the presence hypoxic water was measured situ vertically stratified Bornholm Basin Baltic Sea. Considering all recaptured individuals, use habitat comparable to data derived by traditional survey data, but some G. had migrated towards centre c. 100 m deep basin and spent about a third their time at oxygen saturation <50%, possibly forage on zoobenthos. Maximal residence per visit such limited few hours, allowing for digestion consumed...
Direct engagement of the fishing industry in provision and co-creation knowledge data for research management is increasingly prevalent. In both North Atlantic Pacific, enhanced targeted evident. More needed. Science-Industry collaborative approaches to developing questions, collecting data, interpreting sharing create opportunities information transfer improved understanding ecosystem interactions, stock dynamics, economic incentives, response management. These collaborations require clear...
Cod is the top piscivore predator in Baltic Sea ecosystem. Based on stomach content data from 62 427 cod collected during 1977–1994 and food consumption rates, cannibalism Eastern Western stocks has been quantified using multispecies virtual population analysis. In stock, depending model assumptions, an average of 25–38% 0-group 11–17% 1-group were removed by predation adults. Thus, between age 0 2 a year class may lose about 31% 44% initial number as result cannibalism. Cannibalism lower...
The Baltic Sea comprises a heterogeneous oceanographic environment influencing the spatial and temporal potential for reproductive success of cod (Gadus morhua) sprat (Sprattus sprattus) in different spawning basins. Hence, to quantify stock recruitment dynamics, it is necessary resolve species-specific regional relation size, structure, distribution stock. Furthermore, as species fisheries interactions vary between areas, include these on an area-specific basis. Therefore,...

The degree to which metapopulation processes influence fish stock dynamics is a largely unresolved issue in marine science and management, especially for highly mobile species such as Atlantic cod ( Gadus morhua ) herring Clupea harengus ). Baltic Sea comprises heterogeneous oceanographic environment that structures the spatial temporal distribution of dominant cod, herring, sprat Sprattus sprattus Despite local differences, stocks are traditionally managed homogeneous units. Here, we...
Achieving global and regional policy goals to protect 30% of marine areas by 2030 requires an integrated strategy that incorporates the full complexity ecosystem processes functions. This study (i) introduces a framework for enhancing ecosystem-based conservation management utilising Ecologically or Biologically Significant Marine Area (EBSA) criteria established under Convention on Biological Diversity (CBD), (ii) demonstrates its application in Bay Biscay (Northeast Atlantic), explicitly...
Abstract A new methodology is presented to reconstruct migration pathways of individual fish inhabiting ecosystems with moderate‐to‐strong gradients in temperature or salinity. The method uses measurements ambient pressure, and salinity obtained from electronic data storage tags attached particularly applicable areas negligible tides. We demonstrate the Baltic cod. Hydrographic fields hydrodynamic modelling were used as a geolocation database identify daily positions cod by comparison...
The use of archival tags on fish gives information individual behaviour with an unprecedented high resolution in time. A central problem the analysis data from retrieved is geolocation, namely infererence movements by comparing environmental observations like temperature, tide, day length, etc. result usually represented as a track; however, spatial and temporal variability precision often substantial. In this article, particle filter applied to geolocate Atlantic cod (Gadus morhua) Baltic...
