“…from 5 to 152 cm in Morman et al, 1980). Following Andrade et al (2007), suitable spawning habitat was defined as riffles and runs with at least 30% gravel or cobble substrate. Suitable habitat for larvae consists of sand or silt/mud possibly with organic debris in pools and fine particle deposit area (Applegate, 1950;Hardisty and Potter, 1971).…”

“…However, a recent study combining nest counts and mark-recapture analysis suggests that nest count could provide a reliable and strong proxy of spawner abundance (Hogg et al, 2013). Additionally, river flow, known to influence river colonization by lampreys (Almeida et al, 2002;Andrade et al, 2007;Lucas et al, 2009), has been measured every hour at an automated gauging station all along the entire study period (Direction Régionale de l'Environnement, de l'Aménagement et du Logement Bretagne). Using these measurements, mean daily flow was calculated from April to June during each study year and used as a metric of hydrological conditions during the spawning run.…”

“…small barriers, generally <5-m height) because of their relatively poor swimming ability (Lucas et al, 2009;Jackson and Moser, 2012;Nunn and Cowx, 2012). Although such low-head barriers are generally known to allow fish migration under specific environmental conditions, such as high flow discharge (Andrade et al, 2007;Lucas et al, 2009), they may also hamper fish movement when located downstream of catchment areas (Lucas et al, 2009;Rolls, 2011;Gardner et al, 2013). A recent work showed that they could nonetheless (re-)colonize upstream reaches after low-head barrier removal (Hogg et al, 2013).…”

Habitat fragmentation is an important cause of biodiversity loss in freshwater systems, as worldwide rivers have been fragmented by dams and other hydraulic structures. To restore freshwater fish populations, some barriers have been removed, but the long‐term ecological effects of this removal have been rarely quantified. In the present study, we quantified the effects of barrier removal on river colonization by anadromous sea lamprey (Petromyzon marinus) by analyzing the spatial distribution and nest density in a small coastal river (France) from 1994 to 2011. Our results demonstrated the benefit of dam removal within few years after restoration. Indeed, the spatial distribution of nests shifted significantly upstream and was more uniform throughout the river after removal. Our results also suggest that the spatial patterns of habitat colonization were affected by the density of nests, river flow and connectivity. Finally, although the number of nests was significantly higher after removal, it was not possible to clearly identify the contribution of intrinsic versus external factors involved in this pattern. Further investigations are therefore needed to quantify the potential subsequent effects on juvenile recruitment and the overall population dynamics. Copyright © 2014 John Wiley & Sons, Ltd.

“…Adult lampreys need to find a suitable substrate for spawning, which typically consists of sand and gravel (Malmqvist, 1980). Spawning migration of lampreys is influenced by many different factors such as temperature (Binder and McDonald, 2007), river discharge (Abou-Seedo and Potter, 1979;Almeida et al, 2002), water quality and turbidity, obstacles and dams (Hume, 2012), light (Almeida et al, 2002;Andrade et al, 2007), lunar cycle (Abou-Seedo and Potter, 1979), and pheromones (Vrieze et al, 2010).…”

River ecosystems are often fragmented by artificial structures, such as weirs. For anadromous species, these structures can impede access to upstream spawning sites and ultimately lead to severe population declines. This study focused on the freshwater spawning migration of the sea lamprey, Petromyzon marinus, an anadromous species threatened by habitat fragmentation across its native range. To quantify the cumulative impacts of multiple weirs on upstream‐migrating adults, and to explore the environmental factors affecting migratory movements, passive acoustic telemetry was applied to 56 individuals during their spawning migration in the heavily fragmented River Severn basin, UK. While 89% of tagged sea lamprey passed the first weir upstream of the release site on the main river, only 4% passed the fifth weir. For 85% of migrants, the upstream extent of migration was immediately downstream of a weir. Individuals that passed weirs upstream of the release site (n = 50) took 21.6 ± 2.8 days to reach their most upstream location, experiencing cumulative passage times at weirs of 15.7 ± 2.8 days; these delays constituted a median of 84% of total upstream movement times. Multistate models showed that the weir passage rates of sea lamprey in tidal and non‐tidal areas increased significantly when downstream river level and discharge were elevated. Upstream‐to‐downstream changes in direction were frequent downstream of weirs, but rare in unobstructed river sections. The results provided evidence for a cumulative effect of multiple weirs on sea lamprey movements, substantially delaying upstream migrants and limiting their spawning to atypical habitat. The results also demonstrated the crucial roles of high tides and elevated discharge events in enabling weir passage. Although the Severn Estuary features conservation designations for sea lamprey, this study reveals that barriers are inhibiting their upstream migration, a problem that should be addressed to assist sea lamprey conservation.
