PERSEUS project aims to identify the most relevant pressures exerted on ecosystems of Southern European Seas (SES), highlighting knowledge and data gaps that endanger achievement SES Good Environmental Status (GES) as mandated by Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, a meta-analysis existing literature pressure/impact/knowledge summarized in tables related MSFD descriptors, discriminating open waters from coastal areas. comparative assessment...
Abstract Understanding the distribution of genetic diversity in light past demographic events linked with climatic shifts will help to forecast evolutionary trajectories ecosystems within current context climate change. In this study, mitochondrial sequences and microsatellite loci were analysed using traditional population approaches together Bayesian dating more recent approximate computation scenario testing. The structure history a commercial fish, black scorpionfish, Scorpaena porcus ,...
The demersal fish assemblages of the south-western Sea Marmara and north-eastern Aegean were examined in relation to their biogeographical environmental conditions. Sampling was carried out during bottom trawl surveys conducted five periods between June 2006 August 2007. A total 40 hauls processed, including 16 (38–74 m deep) 24 (63–401 deep). 47,940 individuals, from 91 species 47 families collected. Cluster analysis catch data indicated that there three assemblages, one shelf two (<100...
Abstract The Turkish Island of Gökçeada is located in the northeastern Aegean Sea. In this preliminary study, six collecting stations, at depths 5–15 were sampled. A total 76 species collected by trammel and gill nets (59 species) or trawls (17 species). At each station during season Shannon‐Weaver Diversity index Simpson Dominance calculated. These indices compared with their mean values for station. similarity among stations was estimated Sorenson's (1948) formula. Similarity index, I III...
The aim of this study was to investigate the distribution patterns demersal fishes on continental shelves north-eastern Levantine and Aegean seas. Fish samples were collected by bottom trawl. A total 29 hauls carried out, 15 between 43 121 m depth in Sea 14 65 100 Sea. trawled area for both region 1.87 km 2 . Cluster analysis non-metric multidimensional scaling applied identify grouping. Among 114 fish species found, 84 recorded 64 Fifty found exclusively from northeastern Sea, 30 34 shared...
Summary: This short-term study on commercial discards was carried out in fishing grounds around Gokceada Island the northeastern Aegean Sea, a geographic area where fisheries information is rather limited. A total of 28 bottom trawls were performed between 70 and 410 m depth from December 2009 to February 2010. All samples collected board trawler under conditions. 3143 kg biomass caught valid hauls. Landings accounted for about 67% catch while remaining 33% discarded. Fish species comprised...

The aim of this study is to reconstruct the total historic catch Bulgarian marine fisheries in their Exclusive Economic Zone for time period 1950-2013, including unreported landings, discards, recreational and subsistence catches from ecosystem. landings data officially reported by Bulgaria Food Agriculture Organization United Nations Mediterranean Black Seas (FAO Area 37) were revised line with all available information. reconstructed 1950-2013 was 1.7 times (adjusted) baseline FAO 1.5...
The mean trophic level, i.e., the Mean Trophic Index (MTI) and Temperature of Catch (MTC) were estimated for Turkish waters in Eastern Mediterranean Black Sea based on reconstructed marine fisheries catches (consisting N = 88 species and/or higher taxa) year 1950 to 2010. MTI decreased both regions Turkey, following expectations, but MTC showed different trends these two regions. It increased (by 0.48 °C·decade-1), along with SST Mediterranean, while it fluctuated Sea. This fluctuating...
Conventional narratives explain fish migrations in term of requirements (food, mates, habitats, etc.), with adequate temperatures being optional. Here, using the example a (commercially extinct) stock Black Sea mackerel (Scomber scombrus), we suggest that seasonal are driven by temperature cycles. Therein, acts as constraint determining where can be at any given time, and not one several factors which they would consider when choosing between alternative migration routes. Generalizing,...
The ‘mean temperature of the catch’ (MTC; Cheung et al. 2013, Nature 497: 365-368.) was computed for 59 ichthyoplankton surveys conducted in several regions Eastern Mediterranean (off coasts Greece and Turkey) Black Marmara Seas. This covered 162 fish species whose preferred temperatures (PTs) were derived mainly from data used to derive Aquamaps (see www.aquamaps.org). (geometric mean) MTCs estimates these correlated strongly with observed sea surface (SSTs), once account sampling taken....
One specimen of lancet fish,Notoscopelus kroyeri(Malm, 1861), was collected in March 2007 by commercial bottom trawl the Aegean Sea. This record consists easternmost fish Mediterranean Morphometric and meristic characteristics this species are given.
