Environmental factors as forces structuring the fish community of the Elbe Estuary
Salinity was the most significant physico-chemical factor affecting species richness, species diversity, evenness and total fish biomass, whereas water temperature was the best predictor of total abundance.
The ichthyofaunal composition of the Elbe Estuary: an analysis in space and time
The ichthyofaunal composition exhibited pronounced annual cyclical changes in each region and thus occurred irrespective of whether or not the salinity in a region underwent pronounced changes during the year.
Composition, temporal changes and ecological guild classification of the ichthyofaunas of large European estuaries – a comparison between the Tagus (Portugal) and the Elbe (Germany)
Canonical corresponding analyses (CCA) indicated that, besides intra-annual variables, salinity and mouth distance were two of the most important environmental factors structuring the fish communities in both estuaries.
Endangered anadromous lampreys in the southern Baltic Sea: spatial distribution, long-term trend, population status.
A rebuilding programme is required for the river lamprey; this should definitely contain measures to restore lost spawning sites and the connectivities within the river systems where spawning populations still occur, and Protected areas in estuarine waters with important lamprey migration routes may be an additional measure for the conservation of these anadromous species.
Occurrence and distribution of twaite shad (Alosa fallax Lacépède) in the lower Elbe River, Germany
Low fishing mortality and high spawning success are probably the most important factors determining the relative stability of the twaite shad Elbe population.
Effects of introduced round goby (Neogobius melanostomus) on diet composition and growth of zander (Sander lucioperca), a main predator in European brackish waters.
Diet and growth of zander Sander lucioperca is inspected from the Kiel Canal, northern Germany, to analyse effects of the introduced round goby Neogobius melanostomus as possible prey and it is assumed that this development has the potential to enhance the situation of the local fisheries that are strongly related to the catch ofZander.
First records of the round goby Neogobius melanostomus (Pallas, 1814) in the Elbe River, Germany
The round goby Neogobius melanostomus (Pallas, 1814), a Ponto-Caspian gobiid species, was recorded for the first time in the Elbe River, Germany in May 2008. Between then and June 2013, 22 records
A Review of Predation Impact by 0+ Fish on Zooplankton in Fresh and Brackish Waters of the Temperate Northern Hemisphere
Selective predation by fish larvae on particular small zooplankton prey may be more important than has been detected so far and is lessened by the lower energy requirements of juvenile fish compared with identical biomasses of fish larvae, although larva bioenergetics remains only fragmentarily understood.
Biology of Ruffe (Gymnocephalus cernuus (L.))—A Review of Selected Aspects from European Literature
A multivariable consumption model has been developed to allow rough estimates of daily ration in dependence from water temperature and fish size, and some authors agree that, compared to fresh water, ruffe utilize the better nutritional opportunities in brackish water, which ultimately induces better growth.
