A rapid quantitative method of ultra performance liquid chromatography (UPLC) has been developed for the analysis of 17 amino acids in fish eggs from Acipenser schrenckii, Huso dauricus and Acipenser ruthenus. The analytes were hydrolyzed with 6 0 mol/L HCI. The extraction solution was concentrated under low pressure and neutralized with NaOH solution before derivatization with 6-aminoquinolyl-...

Background: Histamine is an essential biogenic amine produced as a result of microbial decomposition of histidine during seafood processing and storage. The objective of this study was to evaluate histamine concentration in freshwater and marine fish marketed in Stara Zagora region, Bulgaria. Methods: Forty fish samples were purchased from local fish farms and retail stores in Stara Zagora, Bu...

Deletion of the long arm of chromosome 6 (6q) is one of the most common chromosomal alterations in human B-cell lymphomas. Conventional cytogenetic banding analysis and loss-of-heterozygosity (LOH) studies have detected several common regions of deletion ranging across the entire long arm (6q), with no defined recurrent breakpoint yet identified. We describe here a strategy combining chromosome...

The body tilt angle of a fish has a large effect on the acoustic target strength. For an accurate estimation of fish abundance using acoustic methods, it is necessary to measure body tilt angles in free-ranging fish. We measured diurnal body tilt angle distributions of threeline grunt (Parapristipoma trilineatum) while swimming in schools in a fish cage. Micro-acceleration data loggers were use...

The Middle Devonian (Givetian) Valentia Slate Formation in the Iveragh Peninsula, southwest Ireland, is more renowned for second oldest record of tetrapod trackways world than its heavily metamorphosed bone remains. present study focuses on new discoveries non-tetrapod sarcopterygian fish fossils from Formation. Micro-CT scanning technology allows a re-interpretation previously published acanth...

“If all the plastic had been made with oxo-biodegradable technology there would be no ocean plastic garbage patches. ” In the 2012 study published in the Marine Pollution Bulletin “Occurrence of micro-plastics in gastrointestinal tracts of pelagic and demersal fish from the English Channel” it was shown that the majority of plastic particles consumed by the fish were rayon (57.8%) and polyester...
