Blasted rock pollution
This article warns against using blasted rock on site due to pollution risk. In another article, it is suggested to use rocks from weir removal for fish habitat. Which is correct? Bendikhansen (talk) 19:41, 30 September 2020 (UTC)
Maybe the definition sentence could be clearer, i.e.: The principle aim of baffle fishways is to reduce the mean velocity of the flow by placing a series of baffles on the floor and/or walls of a straight channel, which has a rectangular cross-section and a relatively steep slope. These baffles, in shapes of varying complexity, cause secondary helical currents to form which ensure an extremely efficient dissipation of energy in the flow through intense transfer of the momentum (Larinier et al., 2002)Jsanz (talk) 08:32, 2 May 2020 (UTC)Jsanz
Use of non-salmonids in this type of fishways
There are many reference about it, i.e.: This type of fishways can also be used for non-salmonid fish by reducing the slope to 10 % (0.1 m/m) (Bunt et al., 2001; Mallen-Cooper et al., 2007).
