While taxa such as mammals and birds are already given greater consideration in the marine waters, this is unfortunately not yet the case for fish. There are considerable gaps in the assessment of the status of their stocks in the sea .... [ mehr ]

In order to assess the conservation status of fish species, for example for the preparation of red lists, standardized methods for conservation assessments are used. Taking into account relevant environmental parameters, we develop mathematical habitat models ... [ mehr ]

The family Zoarcidae (eelpouts), a group of marine and mostly bottom-dwelling fishes, contains about 300 fish species. 230 of these species belong to the subfamily Lycodinae which is the focus of our research. Some of the Lycodinae species occur at great depth in the deep sea ... [ mehr ]

The last type catalogue for the fish collection of the CeNak was published 10 years ago (Thiel et al. 2009). Since then, taxonomic revisions and descriptions of new fish species have led to changes, so that the publication of a current type catalog for the fish collection of the CeNak has become necessary ...

The fish fauna in river estuaries and other brackish water systems of Europe is often influenced by human activities, e.g. through shipping, fisheries, agriculture, tourism, climate change. In many European estuaries, therefore, native anadromous migratory fish species are declining, endangered or even extinct ... [ mehr ]
