The seasonal distribution of fish eggs and larvae off Sinop, the central southern Black Sea, was studied by using vertical and horizontal tows at two stations at biweekly intervals between January 1999 and November 2000. Besides basic oceanographic parameters, macro gelatinous was also sampled to evaluate their relation to fish eggs and larvae. Eggs or larvae of a total 23 fish species were present in the samples. Most of the species were found to occur during spring and summer. It is observed that especially anchovy (Engraulis encrasicolus) eggs and larvae were highly abundant during this period. Additionally, beginning from May, the eggs and larvae of species, such as Mullus barbatus, Solea lascaris, Trachurus mediterraneus, Ctenolabrus sp., Blennidae and Gobiidae were represented in samples. In the colder period of the year, early life stages of sprat (Sprattus sprattus) were dominant in ichthyoplankton. According to overall quantitative evaluation, anchovy (87%) had superiority in abundance among egg samples and Gobius sp. (35%) among larvae samples.

Two international surveys of anchovy eggs and larvae were carried out in the Black Sea at the beginning of the spawning season in June 1991 and during the main spawning period in July 1992. Horizontal tows demonstrated that the bulk of anchovy eggs acid larvae were distributed in the upper 3-m layer, but in downwelling areas eggs and larvae were found down to 70 m depth. In contrast to earlier studies, vertical hauls obtained during the present investigation contained higher egg numbers in the southern and ...
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 ...
Diel vertical distribution, and herbivory of copepods in the south-western part of the Black Sea
Besiktepe, S (2001-04-01)
The abundance and population structure of copepods were studied in the southwestern part of the Black Sea in May 1994, April and September 1995, April, June and September 1996. Vertical distribution and diel vertical migration of copepods were studied in April and September 1995 and June 1996. In addition, the grazing rates of three size classes of copepods-300-500, 500-1000 and 1000-2000 mum-were estimated in September 1995. The total abundance of copepods was higher in June samples due to the large contri...
Distribution of phytoplankton in the southern Black Sea in summer 1996, spring and autumn 1998
Eker-Develi, E; Kıdeyş, Ahmet Erkan (2003-03-01)
The species composition, abundance, and biomass of micro- (>15 mum) and nano- (<15 mu m) phytoplankton were studied along the southern Black Sea during June-July 1996 and March-April and September 1998. A total of 150 species were identified, similar to 50% of them being dinoflagellates. The average total phytoplankton abundance changed from 77 x 10(3) Cells l(-1) in spring to 110 x 10(3) cells l(-1) in autumn and biomass from 250 mu g l(-1) in summer to 1370 mu g l(-1) in spring. Based on the extensive sam...
Monthly changes in the composition and abundance of meroplankton and pelagic polychaetes of the Cilician basin shelf waters (eastern Mediterranean)
Uysal, Zahit (2005-01-01)
Taxonomic composition of the meroplankton and the pelagic polychaetes of the Cilician basin shelf waters was investigated for the first time. Analysis of monthly net samples shows that the meroplankton and the pelagic polychaetes of the region are represented under 5 phyla, 10 classes, and 34 families. Pelagic nectochaete larvae of the family Spionidae (Polychaeta) and zoeas of family Grapsidae (Decapoda) were the dominating groups throughout the year. Typical stenohaline taxa formed by classes of Enteropne...
