A Curved‐Bar Rack‐Bypass System With Innovative Foil Shaped Bars: Hydraulics, Operational Aspects, and Swimming Behavior of Downstream Moving Brown Trout

open access: yesWater Resources Research, Volume 61, Issue 9, September 2025.
Abstract Curved bar rack ‐ bypass systems (CBR‐BS) are a promising technology for diverting downstream moving fish away from hydropower intakes. A CBR functions as a mechanical behavioral barrier by creating high velocity and pressure gradients along its bars, guiding approaching fish that exhibit avoidance reactions towards the bypass.

A comparison of methods for determining ploidy in white sturgeon (Acipenser transmontanus) [PDF]

open access: yes, 2019
Release of sturgeon with abnormal ploidy into the wild may result in reduced fitness due to lowered fertility in the F2 and subsequent generations. Further, there is evidence that ploidy affects reproductive development and caviar yield.
