“…Preserving functionality of fishways for organisms with different performance or behavioural constraints is difficult and, in some cases, species‐specific design elements need to be incorporated. This is exemplified by the proliferation of structures to accommodate anguilliform swimmers (Kemp, Russon, Vowles & Lucas, ; Moser, Jackson, Tsuzaki & Kemp, ; Vowles, Don, Karageorgopolous, Worthington & Kemp, ). The ideal fish passage structure will allow natural migration of all species and life stages that encounter a barrier, thereby mitigating habitat fragmentation (Agostinho, Agostinho, Pelicice, deAlmeida & Marques, ; Gollmann et al., ).…”

“…Adult Pacific lamprey are also able to climb vertically, and they exhibit this mode of movement at natural obstacles (e.g. waterfalls), at dams and in the laboratory (Kemp, Tsuzaki & Moser, 2009;Moser et al, 2012). This ability has led to the development of Pacific lamprey-specific passage structures that provide routes of passage outside of the traditional salmonid fishways (Moser, Keefer, Pennington, Ogden & Simonson, 2011).…”

The ability of adult Pacific lamprey, Entosphenus tridentatus (Gairdner), to climb has enabled development of lamprey‐specific fishways. Sheer vertical climbing elements are needed for these structures when fishway installation space is limited. A 1.6‐m high aluminium wetted wall was built to test Pacific lamprey vertical climbing in relation to flow and three water delivery mechanisms: overflow, upwelling and sidewelling. Passage success and passage times were recorded for individual Pacific lamprey (n = 122). For those that interacted with the structure (n = 104), 94% successfully ascended the wall (76% on their first attempt). Average time from first interaction with the structure to exit ranged from 19.5 to 47.0 min. Success rates and passage times were not significantly affected by flow or water delivery treatments. This indicates that vertical elements can facilitate lamprey passage in the 0.13–3.59 L min−1 cm−1 flow range tested and may greatly expand the design alternatives in certain situations.

Fishway Bottleneck Relief Models: a Case Study using Radio‐Tagged Pacific Lampreys

Structural or operational changes to fishways can improve fish passage efficiency, but there is often uncertainty regarding which improvements will be most effective. We developed a “bottleneck relief” model using Kaplan–Meier methods to help managers assess where remediation efforts are likely to provide the largest increases in fishway passage. The simulation model uses a matrix of observed efficiency estimates from fishway subsections and incorporates multiple passage attempts by individual tagged fish. In a case study application to test the model, we used radiotelemetry data from 2,170 adult Pacific Lampreys Entosphenus tridentatus at Bonneville Dam (Columbia River, Washington–Oregon), which features multiple fishways and low lamprey passage success (mean fishway passage efficiency ∼0.50; n = 10 years). The model was run iteratively to test potential dam passage benefits from improving efficiency in 20 individual fishway segments. The highest benefits were for improvements at top‐of‐fishway segments and at sites where passage routes converged. Benefits were lower for segments used by fewer fish, segments located downstream from serious bottlenecks, and segments with a limited scope for improvement (i.e., efficiency was already high). The model provides a flexible and objective method for assessing complex fish passage problems and informing remediation decision making. Received December 19, 2013; accepted March 11, 2014
