J. Coeck The candidate will primarily work on projects studying behaviour and population dynamics of diadromous fish species, e.g. European eel, salmon and seatrout, supporting the existing management of the species. diversity of species which should be handled by the Committee. The distribution and status of many diadromous fish species is poorly known.

Diadromous species

Contents include full descriptions of types The effects have been most severe on non-diadromous species (those lacking a marine migratory stage), which are commonly eliminated from streams by trout. Rehabilitating the River Ätran for Diadromous Fish Species.

The majority are from the families Galaxiidae (ﬁve species) and Eleo-tridae (four species), with three from the Anguillidae, two from the Retropinnidae, and one each from the We examined the status of diadromous (migratory between saltwater and freshwater) fishes within the North Atlantic basin, a region of pronounced declines in fisheries for many obligate marine species. Data on these 24 diadromous (22 anadromous, 2 catadromous) species are sparse, except for a few high-value forms. For 35 time series, relative abundances had dropped to less than 98% of historic diadromous species on the US Endangered Species Act and IUCN Red lists were ranked according to the number of species they affect, strong consensus in the ranking of threats across species and between institu-tions emerged. Overexploitation is the most frequent threat to vulnerable marine species, with approxi- (2012).

The species composition is shown for 1997 and 2017. Green, plants and algae; blue, freshwater fish; pink, shellfish; orange, diadromous fish.

Fish species with marine affinity commonly occurred in the shallow littoral habitats of permanently open estuaries. Because these diadromous species all need to migrate upriver from the sea at some stage, they are vulnerable to barriers created by falls, chutes, dams, weirs, and culverts. They also vary widely in their ability to move upriver. Galaxiidae come in many shapes and sizes, but most species rarely exceed 150 mm in length. However, the giant kokopu can grow to over 400 mm in length and 1 kg in weight.
