“…connectivity and natal homing; Secor et al, 2009;Svedäng et al, 2007Svedäng et al, , 2010 and reproductive potential (reproductive timing and size specific fecundity; Kjesbu, 2009;Marshall, 2009;Lowerre-Barbieri et al, 2011) may be important in this context. In the Baltic Sea opportunities for reproduction of flounder vary according to prevailing salinity and oxygen conditions, both spatially due to decreasing salinities from the south towards the north, and temporally due to irregularly occurring inflow events (Nissling et al, 2002;Ustups et al, 2013). Accordingly, information about the annual egg production in different areas is a prerequisite for understanding stock development mechanisms, and thus for setting appropriate management measures.…”

“…The reproductive success of these populations, however, can vary spatially and temporally. Success is governed by highly irregular saline water inflow events, influencing salinity conditions as well as oxygen conditions (Nissling et al, 2002;Segerstråle, 1969;Ustups et al, 2013). These events affect stock abundance and distribution, including for flounder (Drews, 1999;Ojaveer et al, 1985).…”

“…Fish were assigned to different length groups that correspond to ontogenetic shifts and associated changes in their feeding patterns. Flatfish juveniles were divided into diet-based length groups based on feeding information from studies conducted before the invasion of the round goby (Ustups et al, 2013). Four length groups were used for flounder (b 3.5 cm (FL1), 3.5-5 cm (FL2), 5.5-9.5 cm (FL3), and 10-15 cm (FL4)) and three length groups were used for turbot juveniles (b4 cm (TU1), 4-8 cm (TU2), and 9-18 cm (TU3)).…”

“…life stages of pelagic spawning flounder (eggs, larvae, juveniles) over the past 30 years (Ustups et al 2013). The hypothesis that the available reproductive volume (habitat), defined as the water column with dissolved oxygen larger than 1 ml/l and salinity between 10.6 and 12 PSU, affects the survival of flounder ichthyoplankton and determines recruitment success was evaluated.…”

Essential fish habitats (EFH)Conclusions from a workshop on the importance, mapping, monitoring, threats and conservation of coastal EFH in the Baltic Sea Patrik Kraufvelin, Ulf Bergström, Annukka Lehikoinen, This publication has been published with financial support by the Nordic Council of Ministers. However, the contents of this publication do not necessarily reflect the views, policies or recommendations of the Nordic Council of Ministers. www.norden.org/nordpubNordic co-operation Nordic co-operation is one of the world's most extensive forms of regional collaboration, involving Denmark, Finland, Iceland, Norway, Sweden, and the Faroe Islands, Greenland, and Åland.Nordic co-operation has firm traditions in politics, the economy, and culture. It plays an important role in European and international collaboration, and aims at creating a strong Nordic community in a strong Europe.Nordic co-operation seeks to safeguard Nordic and regional interests and principles in the global community. Common Nordic values help the region solidify its position as one of the world's most innovative and competitive. Nordic Council of Ministers PrefaceMany coastal and offshore fish species in the Baltic Sea are strongly dependent on shallow and sheltered near-shore habitats for their spawning, nursery, feeding and migration. Still, the role of these essential fish habitats, EFH, for the development and support of fish stocks and communities has received relatively little attention. As EFH in the Baltic often are found in the same parts of the coastal zone that are highly utilized and valued by humans, they are subjected to many threats and therefore management needs are urgent. In addition, EFH provide and support important ecosystem services and are included in national and international agreements and legislative acts as the Baltic Sea Action Plan, Habitats Directive and Marine Strategy Framework Directive. Despite this, the conservation status of EFH is generally poor in the region. As a result of these shortcomings and needs, the Nordic Council of Ministers financed a project including a workshop with Baltic Sea experts with the aim to review the importance of, protection of and threats to coastal EFH in the Baltic Sea. This report describes the results of the project, primarily focusing on the outcome of the workshop. SummaryMany fish species in the Baltic Sea are highly dependent on shallow and sheltered coastal habitats that they use for spawning, nursery, feeding and migration. Still, the role of these essential fish habitats (EFH) for the development and support of fish stocks and communities has received relatively little attention, even though there is general consensus among scientists about their critical importance. Little is also known about the major threats to EFH, and their conservation status in different countries has previously not been reviewed. As EFH often are found in the same parts of the coastal zone that are also highly valued by humans, this gap in knowledge needs to be addressed. Hence, there is an...
