Estimated counts and sea trout individual data from the upstream trap on the Bresle (France).

DOI

Data consists of sea trout yearly estimated counts for smolts and spawners from 1984 to 2017 on the Bresle river and individual data on spawners from 1981 to 2017. It was collected for the Environmental Research Observatory (ORE) on Diadromous Fish in Coastal rivers (DiaPFC). ORE DiaPFC is a research infrastructure focused on studying the influence of human-induced and environmental changes (mainly agriculture and climate) on salmonids. The River Bresle is 72 km long and has a mean slope of 0,26%. It drains a basin of 750 km2 and flows north-west through the Normandy-Picardy plateau ending into the English Channel at Le Tréport. It lies within a chalky geological zone and is fed from alluvial deposits. The water quality is generally fair, except for the occasional pollution by chronic agricultural run-offs. The mean flow is 7,3m3/s, with the highest mean flow in February (mean = 9,4 m3/s) and the lowest in September (mean = 6.4 m3/s).
