Flathead grey mullet, Mugil cephalus, with mass whitish cystlike plasmodia on their scales were collected at Kerchensky preglass of the Black Sea in 2015. The prevalence of infected fish varied from 15% in spring, reached 100% in summer, and declined to 2.5% in autumn. No fish mortality was detected. The spores were oval in frontal view, tapering to a blunt apex. Two unequal polar capsules were pyriform and extended over the anterior half of spore. Spores were 8.2±0.03 µm (7.9-8.4) long, 5.9±0.23 µm (5.2-7.3) wide, and 4.4±0.17 µm (4.0-4.7) thick. Two pyriform and unequal polar capsules were observed (4.0±0.07 µm (3.3-4.5) long, and 1.5±0.24 µm (1.1-1.8) wide). The investigation of nucleotide sequences of the 18S rDNA gene of the myxosporean spores from scales with universal primer А (5′-ACCTGGTTGATCCTGCCAGT-3′) and В (5′-TGATCCTTCTGCAGGTTCACCTAC-3′) showed 100% identity with episquamalis, and 99 % with M. bizerti, M. ichkeulensis, M. spinacurvata and Myxobolus sp. previously detected in mullets. The results obtained from the present study reveal that M. episquamalis, found on the scales of M. cephalus from Kerchensky preglass of the Black Sea, is new record for Russian waters.

Abstract Eighteen sterols were identified in Botryllus schlosseri, stanols being the main sterols. The sterol composition is in agreement with our recent paper on taxonomic separation of tunicates into three groups. Again we found in invertebrates of the Black Sea sterols with a (22Z)-double bond. This confirms the presence of such sterols in nature. The composition of the phospholipids appeared to be complex, and twelve groups of them were identified in Botryllus schlossen. The main representatives of phospholipids appeared to be phosphatidylcholine and phosphatidylethanolamine. Only four volatile compounds were identified, which is unusual for marine invertebrates.
