This study provides updated the length-weight relationships and Fulton's condition factor of 28 fish species belonging to 23 families from the Black Sea. Samples were collected along the depths between 0-100 meters by demersal trawl surveys conducted seasonally from May 2017 to September 2019. A total of 83,885 specimens were collected. The length-weight relationships and Fulton's condition factor, minimum, maximum and mean lengths, total weights, descriptive statistics, and growth type were provided for all the species. The results indicate that LWR parameters of b varied from 2.2039 to 3.737 and Fulton's condition factor varied between 0.004 and 1.18. These findings could be useful for monitoring and management of sustainable fisheries and habitat health.


Relative body condition of red mullet (Mullus barbatus) and its applicability as an indicator of environmental status

This study examines the ratio between length and body weight of 4191 specimens of a prevalent, tertiary tropic level Teleost fish, red mullet (Mullus barbatus) sampled using a standard survey protocol from more than 2500 km by the coasts of Turkey extending along the Mediterranean, Aegean, and the Black Sea. The study's primary aim was to investigate whether there is a correspondence between the body condition of the red mullet and the environmental status independently determined based on lower trophic lev...
Chemical composition, respiration and feeding rates of the new alien ctenophore, Beroe ovata, in the Black Sea
Finenko, GA; Anninsky, BE; Romanova, ZA; Abolmasova, GI; Kıdeyş, Ahmet Erkan (2001-05-01)
Maximum daily rations of the ctenophore Beroe ovata Brugiere and predatory impacts on the Mnemiopsis leidyi A. Agassiz population were estimated via digestion time, prey biomass and predator and prey density in Sevastopol Bay and adjacent water regions. Digestion times ranged from 0.5 to 5.2 h and depended on the prey/predator weight ratio. Overall, the mean daily ration was 45% of B. ovata wet weight. Preliminary conclusions are given on the B. ovata population as an effective control of the M. leidyi popu...
Spatio-temporal patterns and environmental controls of small pelagic fish body condition from contrasted Mediterranean areas
Brosset, Pablo; et. al. (2017-02-01)
Small pelagic fish are among the most ecologically and economically important marine fish species and are characterized by large fluctuations all over the world. In the Mediterranean Sea, low catches and biomass of anchovies and sardines have been described in some areas during the last decade, resulting in important fisheries crises. Therefore, we studied anchovy and sardine body condition variability, a key index of population health and its response to environmental and anthropogenic changes. Wide tempor...
Study of Copepod Species from the Western Black Seain the Cruise r/v Knorr during May June 2001
Selifonova, Janet P; Shmeleva, Alexandra A; Kıdeyş, Ahmet Erkan (Institute of Biodiversity and Ecosystem Research, Bulgarian Academy of Sciences, 2008-01-01)
Results of investigation of copepod fauna in the western Black Sea are obtained in May-June 2001. 49 taxa have been found including 33 taxa that are not of the Black Sea origin. The problem of intensifi cation of process of copepod fauna Mediterranization in the Black Sea basin is discussed.
Genetic structure of modern and ancient swordfish populations from coasts of Turkey
Yüncü, Eren; Togan, İnci Zehra; Department of Biology (2017)
In this study, partial mitochondrial DNA (mtDNA) and 8 microsatellite loci of swordfish collected from Northern Levantine Sea and Northern Aegean Sea were analyzed. Also same mtDNA region of ancient swordfish samples unearthed from Yenikapı excavation were sequenced. Obtained sequences were evaluated comparatively with the sequences from Balearic Sea, Ligurian Sea, Ionian Sea and Southern Aegean Sea, available in databases. Analysis of the molecular variance revealed a significant differentiation between We...
