Dear List members,

 I'm looking for informations on the possibility that successive
sections on a fish ladder were placement of a gravel substrat will be
performed, would be colonise and use by fish for feeding. The proposed
height between basins (dimension of the basins 3 m by 3.5 m) will be 150
mm, less than usually built on other fish ladder, that will allow more fish
species to ascend the fishway.

Thanks for your help
