Lithophilic spawning fish
Web23 The spawning success of lithophilic salmonids is strongly influenced by the fine sediment 24 content (‘fines’) of spawning substrates, yet knowledge on the impacts of fines on the 25 spawning of non-salmonid lithophiles remains limited, despite their ecological and socio-26 economic importance in European rivers. WebIn the rivers with impacts from previous and current mining operations, the layer of deposited sediment may be as much as 70 cm thick. This makes the rivers unsuitable for spawning of lithophilic fish species, including important species such as taimen, lenok, and grayling.
