“…Imre et al, 2010;Wagner et al, 2011 application, especially in large rivers (McLean, 2014). The trapping can also be highly selective for P. marinus 650 (McLaughlin et al, 2007). Trapping data also indicate the spatial and temporal dynamics of the P. marinus populations, enabling population estimates and the costeffectiveness assessment of the sea lamprey control programs (Mullett et al, 2003;Jones, 2007).…”

“…Developments in trap design have 660 resulted in P. marinus specific traps, incorporating decreasing gradations of funnel opening size (Johnson et al, 2005;McLaughlin et al, 2007). Transportable traps are usually sheet mesh cages, and temporally placed at a fixed structure in rives during the migration period and 665 removed afterwards (McLaughlin et al, 2007). Estimates of annual trapping efficiency using mark-recapture methods suggest around 40-70% of adults can be trapped (Haeseker et al, 2007).…”

“…These were frequently constructed on streams in strategic locations throughout the Great Lakes basin, with around 61 installed or modified between 1958 and 1999, with others added in 90 streams after 1999 (Lavis et al, 2003). Approximately 20 dams were also estab-615 lished for other purposes that have since been modified to also prevent adult movement, and there are also a number of existing dams and traditional fish passes that limit P. marinus access to spawning habitat (Lavis et al, 2003;McLaughlin et al, 2007).…”

“…There are two types of sea lamprey traps used, permanent and portable (McLaughlin et al, 2007). Permanent traps are often installed into barriers or fish passes, and are usually constructed from concrete or steel in a square or rectangular shape.…”

1. Recent advances in the understanding of lamprey migrations have led to concerns over the impacts of obstructions on the demography of many species. This study investigated sea lamprey (Petromyzon marinus) larvae (ammocoetes) in two adjacent but contrasting rivers, both designated Special Areas of Conservation under the EC Habitats Directive (92/43/EEC), one (the River Wye) with a small number of potential migration obstructions in its upper reaches and one (the River Usk) with obstacles along its course. The geographical distributions, densities and age structures of the ammocoete populations were examined in relation to the locations of potential obstructions to the spawning migrations of anadromous adults. 2. A minimum of three age classes was recorded as far as 200 km upstream of the mouth of the River Wye (93% of the length of the mainstem), demonstrating that adults regularly migrate to the upper reaches of the catchment (downstream of a natural waterfall). By contrast, sea lamprey ammocoetes appeared to be absent (in suitable habitat) from 20 km (17%) of the River Usk, and there was a reduction in density, prevalence and the number of age classes upstream of two putative spawning-migration obstructions.3. This study highlights some of the potential impacts of habitat fragmentation by obstructions on the spawning migrations of anadromous species, as inferred from ammocoete demography.When used in combination to compare contiguous reaches, ammocoete densities, prevalence and age structure may be a useful indicator of which structures are likely to be important migration obstructions, and where further studies or mitigation efforts should be focused. It is likely that passage past some obstructions is enhanced if high river levels occur during the spawning migration, but there is a need to facilitate passage during all conditions, to improve access to under-exploited spawning and nursery areas.
