Can aspects of the discharge regime associated with juvenile Atlantic salmon ( Salmo salar L.) and trout ( S. trutta L.) densities be identified using historical monitoring data from five UK rivers?
Abstract Understanding salmonid discharge requirements can help inform management to conserve wild populations in a changing climate. This study developed Bayesian hierarchical mixed‐effects models relating 0+ Atlantic salmon ( Salmo salar L.) and trout ( S almo trutta L.) densities to different asp...
