The objective of Oceanological and Hydrobiological Studies, an international journal published by the University of Gdańsk in cooperation with the Academic Publishing Company Walter DeGruyter, is to provide the most comprehensive and reliable source of information on the current knowledge in the fields of science related to both oceanology and hydrobiology. The main emphasis is on publishing high quality articles, easily available to scientists from all over the world. As an editorial team, we are convinced that Oceanological and Hydrobiological Studies will continue to grow as a journal meant for scientists and researchers who wish to keep abreast of the latest developments in these fields of science.
Hexabromocyclododecane contamination of herring gulls in the coastal area of the southern Baltic Sea
Muscles and livers of herring gulls (Larus argentatus) found in the coastal area of the southern Baltic Sea were tested for the presence of hexabromocyclododecane (HBCD) isomers. They were detected in the muscles (ΣHBCD =
Accumulation of heavy metals (Fe, Zn, Cu, Mn, Cd and Pb) in mullets Planiliza subviridis (Valenciennes, 1836) and Ellochelon vaigiensis (Quoy & Gaimard, 1825) from Damb Harbor, Balochistan, Pakistan
In this study, muscle samples collected from Planiliza subviridis (Valenciennes, 1836) and Ellochelon vaigiensis (Quoy & Gaimard, 1825) caught on the Balochistan coast (Damb Harbor) between January and December 2015 (during the northeast monsoon, post-monsoon
Navicula dermochelycola sp. nov., presumably an exclusively epizoic diatom on sea turtles Dermochelys coriacea and Lepidochelys olivacea from French Guiana
Epizoic diatom communities were studied on four turtle species (Chelonia mydas L., Eretmochelys imbricata L., Lepidochelys olivacea Eschscholtz and Dermochelys coriacea Vandelli) from the Eastern Caribbean, the Equatorial West Atlantic and the South Pacific. In
Use of rotifer trophic state indices to show the effect of hydrobionts and nutrients on water trophic status in mesocosms
We have determined how Crustacea, zebra mussels (Dreissena polymorpha), fish and nutrients affect the trophic state in mesocosms filled with water collected from the pelagic zone of a eutrophic lake. We hypothesized that the pool
Diversity and ecological characteristic of algae and cyanobacteria of thermokarst lakes in Yakutia (northeastern Russia)
A total of 437 species (453 with infraspecific taxa) of algae and Cyanobacteria were identified in 2034 samples collected during the first research on nine thermokarst lakes in Yakutia carried out in 1986–1994 and 2001–2015.
Distribution and community structure of microphytoplankton in relation to increasing anthropogenic impact along coastal waters of Jeddah, the central Red Sea
Seasonal distribution and diversity of surface phytoplankton have been studied in relation to anthropogenic activities at seven locations along the coastal waters of Jeddah, Saudi Arabia in 2017. The concentration of nitrite, nitrate, ammonia, phosphate
Spat efficiency in the pearl oyster Pinctada radiata (Leach, 1814) in the surface and bottom water at Karantina Island
The present study was carried out to determine the spat efficiency in the pearl oyster (Pinctada radiata, Leach, 1814) in surface and bottom water at Karantina Island (Izmir/Turkey). Polyethylene mesh bags were used as collectors.
Long-term changes in phytoplankton and macrophyte communities in an eutrophic shallow reservoir and prospects for its restoration
Long-term changes in hydrochemistry and community structure of phytoplankton and macrophytes were analyzed in the Sestroretskiy Razliv reservoir (northwestern Russia). The average content of total phosphorus (TP) in May–October increased from 73 µg Р l−1
