Lithophilic spawning
WebSecondary channels probably also function as spawning areas for L. idus and G. gobio but not for lithophilic species ( B. barbus, Leuciscus leuciscus) since suitable substrate lacks. Eurytopic species ( Abramis brama , Rutilus rutilus and Stizostedion lucioperca ) use all types of floodplain water body to reproduce. WebヱヰΑ SCDRS identified lack of spawning habitat as a factor limiting Lake Sturgeon spawning success ヱヰΒ (Manny et al. 2015). ヱヰΓ To increase suitable spawning habitat for lithophilic spawning fishes such as Lake ヱヱヰ Sturgeon, seven spawning reefs were constructed with 8-15 cm diameter fractured limestone

WebSpawning habitat limitations may be the mechanism through which these species have been reduced in the urbanized faunas. While this presents a strong general hypothesis, information regarding the specific habitat requirements and responses to urbanization of these species is limited. WebDredging Austrian Danube harbours becomes necessary to keep the navigation channel free from bed sediment and to insure safe navigation, especially after major floods. In most cases, the excavated substrate is deposited in the free-flowing river section in the vicinity of the mouth of a harbour. The effects of harbour dredging on the biota need to be studied …
