Finally, the protected fish species, European weather loach (Misgurnus fossilis) and spined loach
(Cobitis taenia), will also benefit from project measures.
Enhancement of natural river reproduction for river lamprey, Atlantic salmon, European bullhead (Cottus gabio), spined loach (Cobitis taenia) and thick-shelled river mussel; and
Reductions in river lamprey, Atlantic salmon, European bullhead and spined loach mortality to 80% below current levels in the Drawa river drainage basin;
The valley is also home to a number of rare and threatened species, including the spined loach
(Cobitis taenia) and pool frogs (Rana lessonae), both of which are listed in the annexes of the Habitat Directive.
The habitat improvements should also benefit three other Annex II-listed species of EU importance associated with the habitats: the spined loach
(Cobitis taenia), mud loach (Misgurnus fossilis) and water plantain (Luronium natans); as well as the Annex I habitat, hard oligo-mesotrophic waters with benthic vegetation of Chara.
Achieving a sustainable hydrological management system for the wetland habitats will benefit the conservation status of the fish species brook lamprey (Lampetra planeri) and spined loach
(Cobitis taenia), which are listed in Annex II of the Habitats Directive.
The river and regularly flooded meadow, was extremely important habitat and spawning ground for many fish species, including the EU targeted asp (Aspius aspius), spined loach
(Cobitis taenia) and mud loach (Misgurnus fossilis).
Such restoration will have a beneficial impact on the European bitterling, spined loach
, bluethroat, common kingfisher, little bittern and purple heron.
