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.

Seasonality of Mesozooplankton in the Southern Black Sea off Sinop Between 2002 and 2004
Üstün, Funda; Bat, Levent; Şahin, Fatih; Birinci Özdemir, Zekiye; Kıdeyş, Ahmet Erkan (2016-12-01)
The monthly and long-term fluctuations of mesozooplankton abundance, biomass, and taxonomic composition in the Sinop inner harbor (southern Black Sea) between 2005 and 2009 are presented in the present study. In total, 31 mesozooplankton taxa were identified during the study. The recorded average mesozooplankton abundance and biomass were 34,323 ± 7580 ind. m and 1208 ± 460 mg m in 2005, 95,063 ± 31,434 ind m and 1787 ± 604 mg m in 2006, 97,626 ± 12,141 ind m and 1034 ± 20 mg m in 2007, 91,918 ± 10,476 ind ...

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...
Population dynamics and ecology of the invasive veined rapa whelk, Rapana venosa in the southern Black Sea
MUTLU, ERHAN; Kıdeyş, Ahmet Erkan; Şahin, Fatih; Erik, Gökhan; Aksu, Hakan; Erdem, Ercan; Karayücel, Sedat; Bat, Levent (2022-05-05)
© 2022 Elsevier LtdSpatial and temporal changes in some ecological characteristics (i.e. biomass, abundance, morphometrics, sex-composition, growth parameters and population dynamics) of the invasive veined rapa whelk (Rapana venosa) were studied off Sinop Bay, in the southern Black Sea. The whelk specimens were sampled from three depths (15 m, 25 m and 35 m) at monthly intervals between November 2005 and October 2007. Custom-made pots were deployed for the capture of R. venosa individuals. Monthly distribu...
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...
Life History Strategies of Non-Indigenous Por’s Goatfish (Upeneus pori) and Confamilial Red Mullet (Mullus barbatus) in The Northeastern Mediterranean
Ok, Meltem; Gücü, Ali Cemal (2013-11-01)
In this study, allocation of energy and time for growth and reproduction of M. barbatus and U. pori were investigated to understand life history strategies adapted by a native and non-indigenous confamilial species based on multidisciplinary survey data collected in three successive years in the NE Mediterranean. The results indicated that the species seem to fulfill their biological activities within a short period of time when the highest productivity is reached in the area. The native fish exhibits fast ...
