Feeding ecology, growth and reproductive biology of round goby Neogobius melanostomus (Pallas, 1814) in the brackish Kiel Canal

Autor: Victoria Magath, Mattias Hempel, Ralf Thiel, Rüdiger Neukamm

Publikováno v: Marine Biodiversity. 49:795-807

We studied diet, growth and reproductive biology of round goby Neogobius melanostomus from the Kiel Canal, northern Germany, to give an insight into the life cycle of this species in a brackish water canal. Crustaceans had the highest importance in t

Publikováno v: Freese, M.; Suehring, R.; Pohlmann, J.-D.; Wolschke, H.; Magath, V.; Ebinghaus, R.; Hanel, R.: A question of origin: dioxin-like PCBs and their relevance in stock management of European eels. In: Ecotoxicology. Vol. 25 (2016) 1, 41-55. (DOI: 10.1007/s10646-015-1565-y)

The stock of European Eel (Anguilla anguilla L.) has reached an all-time low in 2011. Spawner quality of mature eels in terms of health status and fitness is considered one of the key elements for successful migration and reproduction. Dioxin-like Po

Link between estuarine fish abundances and prey choice of the great cormorant Phalacrocorax carbo (Aves, Phalacrocoracidae)

Autor: Victoria Magath, Uwe Helbing, Ralf Thiel, Rudolf Abraham

Publikováno v: Hydrobiologia. 763:313-327

Prey choice of opportunistic piscivorous birds, such as Phalacrocoracidae, may primarily depend on prey abundance in rivers. Estuaries, the most downstream river stretches, often represent important feeding sites for piscivorous birds, but are usuall

Migration behaviour of twaite shadAlosa fallaxassessed by otolith Sr:Ca and Ba:Ca profiles

Autor: Lasse Marohn, Victoria Magath, Jan Dierking, Matthias Frische, Ralf Thiel, Jan Fietzke

Publikováno v: Journal of Fish Biology. 82:1871-1887

Individual migration behaviour during the juvenile and adult life phase of the anadromous twaite shad Alosa fallax in the Elbe estuary was examined using otolith Sr:Ca and Ba:Ca profiles. Between hatching and the end of the first year of life, juveni

Stock recovery, spawning period and spawning area expansion of the twaite shad Alosa fallax in the Elbe estuary, southern North Sea

Autor: Ralf Thiel, Victoria Magath

Publikováno v: Endangered Species Research, Vol 20, Iss 2, Pp 109-119 (2013)

After a serious decline in the past, some twaite shad Alosa fallax populations have significantly recovered during the last decade. Although increasing numbers of the species occur in areas of the southern North Sea, detailed quantitative analyses ha
