Investigating pros and cons of passive stow net and active trawl fishery in shallow coastal waters for monitoring pelagic fish species.
A conservation assessment was carried out of 94 fish and lamprey species occurring in the German North Sea and Baltic Sea waters. One species (1.1 %) is extinct. Thirteen species (13.8 %) were classified into one of the following three threat categories: Critically Endangered, Endangered or Vulnerable. The degree of threat of 4 species (4.3 %) is i...
Wagler, H., Berghahn, R., and Vorberg, R. 2009. The fishery for whiteweed, Sertularia cupressina (Cnidaria, Hydrozoa), in the Wadden Sea, Germany: history and anthropogenic effects. – ICES Journal of Marine Science, 66: 2116–2120.The whiteweed fishery in the German Wadden Sea did not close as a consequence of the loss of whiteweed beds, but rather...
The shallow waters of the Wadden Sea and the connected estuaries and coastal waters provide indispensable habitats for a whole range of fish species in the course of their life-cycle. These areas provide spawning, feeding and nursery grounds and serve as transit route for diadromous species migrating between marine and fresh water habitats. Environ...
Intensive beam-trawl fishery on brown shrimps (Crangon crangon) occurs along the German North Sea coast. Fishing effort has increased constantly over recent decades. Simultaneously, changes in the benthos of the Wadden Sea have been observed. Besides shifts in species composition of the communities and the disappearance of oyster beds, there has be...
The application of underwater imaging systems in benthological investigations in the subtidal zone of the Wadden Sea extend the range of possibilities offered by traditional benthos sampling gear such as research trawl, dredge, grab or corer. An underwater camera yields information on the bottom sediment type and epibenthic fauna. Due to the limite...
