“…Movements can be tracked in both 2D and 3D, allowing measurements of fish size and analyses of fish swimming kinematics and behaviour (Neuswanger, Wipfli, Rosenberger, & Hughes, ; Voesenek et al, ). Field applications are also feasible where underwater visibility is good: for example, Vivancos and Closs () used 3D videogrammetry to monitor the drift‐feeding behaviour of Galaxias anomalus Stokell, 1959 (mean total length 35.8 mm) in a stream environment. Environmental DNA may be a useful tool for evaluating the impacts of migration barriers at a landscape scale, but cannot provide the details on the fine‐scale movements that are required to help advance structure design.…”

1. Amphidromy is a form of migratory life history typified by the reproduction of fish in freshwater environments, the early downstream dispersal of post-hatch larvae to marine environments, and the return of small-bodied young juveniles to freshwater environments for growth to adulthood. Island freshwater fish communities are frequently dominated by fish species with amphidromous life histories.2. Amphidromous life cycles leave fish communities highly susceptible to habitat modification and disruptions to connectivity across marine and freshwater environments. This means that managing waterway connectivity is fundamental to their conservation; however, the unique and often geographically restricted amphidromous communities that characterize many small island nations have received little consideration in the development of strategies for the management of fish passage.3. The ecology and locomotory capabilities of amphidromous species are often poorly studied, partly because their small size at migratory life stages renders current state-of-the-art in situ biotelemetry methods unsuitable. The small size of fish also means that seemingly small obstructions can severely impede migrations. 4. The steps necessary to advance the management of fish passage for island fish communities are: curating and maintaining barrier inventories; evaluating barrier permeability; developing effective barrier mitigation options; and prioritizing restoration and conservation efforts. 5. New methods for understanding the ecology and locomotory capabilities and behaviour of amphidromous fishes are required to advance the management of fish passage for island fish communities. Fish passage solutions that imitate natural streams, such as those promoted in new guidelines in New Zealand, may be the most effective way of improving waterway connectivity; however, integrated approaches to freshwater fish conservation that account for meta-population dynamics, in combination with the management of fish passage, are necessary to optimize conservation outcomes for amphidromous species.

“…New imaging systems and software are providing more accurate measurements of fish positions (Vivancos and Closs 2015;Neuswanger et al 2016), but Nakano's papers are still the standard for defining the principles of how salmonid behavior creates the dominance hierarchies that are ubiquitous in natural streams.…”

Crossing boundaries: Shigeru Nakano's enduring legacy for ecology

Shigeru Nakano was a Japanese ecologist whose work crossed boundaries among subdisciplines in ecology, between aquatic and terrestrial habitats, and between different languages and cultures. He published his first paper in 1985 while still an undergraduate, and is well known for his early research on the individual behavior of stream salmonids in dominance hierarchies. Shortly after completing his Master's degree in 1987 he began collaborating with many graduate students and other scientists, including those from the US, and expanded his research to include factors controlling stream salmonid distribution and abundance across spatial scales ranging from local to landscape levels. In 1995 he moved to a research station in southwestern Hokkaido and began new collaborative research on interactions between forest and stream food webs. Nakano pioneered large-scale field experiments using greenhouses to sever the reciprocal fluxes of invertebrate prey between stream and riparian food webs. The strong direct and indirect effects of isolating these food webs from each other on organisms ranging from stream algae to fish, riparian spiders, and bats have revealed new linkages and explained phenomena that were previously unexplained. When combined with similar results from other investigators, they have created a paradigm shift in ecology. Shigeru Nakano was lost at sea in Baja California on March 27, 2000 at the age of 37, but key papers from his 15-year career set new standards for rigor, detail, and synthesis. They continue to be highly cited and inspire new research, and to foster new collaborations among Japanese and western scientists.

Ecologists are now widely utilising video data to quantify the behaviours and interactions of animals in the wild. This process can be facilitated by collecting videos in stereo, which can provide information about animals' positions, movements and behaviours in three‐dimensions (3D). However, there are no published designs that can collect underwater 3D stereo data at high spatial and temporal resolutions for extended periods (days). Here, we present complete hardware and software solutions for a long‐running, open‐source, underwater stereo camera rig, costing £1337. This stereo camera can continuously record aquatic species and their behaviours/interactions in high resolution (1080 p and 30 fps) and in 3D, over multiple days. We provide full design guides for the cameras and a travel‐friendly rig, and include guidance and open‐source code for calibrating the cameras in space and time. We also show how these cameras could be used to track animals' body parts and positions, and how their size, posture and behaviour can be inferred. This stereo camera will facilitate the collection of high‐resolution ecological and behavioural data, such as affiliative, agonistic or trophic interactions between species, which can inform us about the health and structure of ecosystems. These data will assist ecologists and conservationists in monitoring and understanding the impacts of current environmental pressures on ecosystem functioning.
