Managed realignment for habitat compensation: Use of a new intertidal habitat by fishes (2015)
Journal Article
Nunn, A., Clifton-Dey, D., & Cowx, I. (2016). Managed realignment for habitat compensation: Use of a new intertidal habitat by fishes. Ecological engineering, 87, 71-79. https://doi.org/10.1016/j.ecoleng.2015.11.009

Managed realignment has become an increasingly common mechanism to increase the efficiency and sustainability of flood defences, reduce defence costs or compensate for habitat losses. This study investigated the use by fishes of a new intertidal habi... Read More about Managed realignment for habitat compensation: Use of a new intertidal habitat by fishes.

The habitat use of young-of-the-year fishes during and after floods of varying timing and magnitude in a constrained lowland river (2014)
Journal Article
Bolland, J. D., Nunn, A. D., Lucas, M. C., & Cowx, I. G. (2015). The habitat use of young-of-the-year fishes during and after floods of varying timing and magnitude in a constrained lowland river. Ecological engineering, 75(February), 434-440. https://doi.org/10.1016/j.ecoleng.2014.12.009

Globally, channelisation and artificial levee construction have reduced rivers to single-thread channels isolated from their floodplains. These modifications may be particularly detrimental to fish during floods, because of increased severity of cond...

Fisheries Management and Ecology, 23(1), 1-11. https://doi.org/10.1111/fme.12074

The European Non-native Species in Aquaculture Risk Analysis Scheme (ENSARS) was developed in response to European 'Council Regulation No. 708/2007 of 11 June 2007 concerning use of alien and locally absent species in aquaculture' to provide protocol...

Temporal and spatial variations in the abundance and population structure of the spined loach (Cobitis taenia), a scarce fish species: implications for condition assessment and conservation (2014)
Journal Article
Nunn, A. D., Tewson, L. H., Bolland, J. D., Harvey, J. P., & Cowx, I. G. (2014). Temporal and spatial variations in the abundance and population structure of the spined loach (Cobitis taenia), a scarce fish species: implications for condition assessment and conservation. Aquatic conservation : marine and freshwater ecosystems, 24(6), 818-830. https://doi.org/10.1002/aqc.2451

Effective conservation of protected species requires accurate estimates of the status of their populations. In the UK, this led to the production of a series of sampling protocols to establish the status of designated species against predetermined co...

Flow requirements of non-salmonids (2012)
Journal Article
Cowx, I. G., Noble, R. A., Nunn, A. D., Bolland, J., Walton, S., Peirson, G., & Harvey, J. P. (2012). Flow requirements of non-salmonids. Fisheries Management and Ecology, 19(6), 548-556. https://doi.org/10.1111/fme.12017

Research into the relationships between non-salmonid fish population dynamics and discharge is in its infancy compared with salmonids, thus compromising the ability to manage flows in rivers and maintain ecological status. This study reviews the pote... Read More about Flow requirements of non-salmonids.

Diel and seasonal variations in the population dynamics of Hemimysis anomala, a non-indigenous mysid: implications for surveillance and management (2012)
Journal Article
Nunn, A., & Cowx, I. G. (2012). Diel and seasonal variations in the population dynamics of Hemimysis anomala, a non-indigenous mysid: implications for surveillance and management. Aquatic Invasions, 7(3), 357-365. https://doi.org/10.3391/ai.2012.7.3.007

This study investigated diel and seasonal variations in the population dynamics of Hemimysis anomala, a non-indigenous mysid originating from the Ponto-Caspian region. There were strong diel variations in the abundance (catch-per-unit-effort; CPUE) o...

Restoring river connectivity: Prioritizing passage improvements for diadromous fishes and lampreys (2012)
Journal Article

Physical obstructions are becoming increasingly recognized as major factors influencing the migrations, population structures, spawning success and recruitment of freshwater organisms. This paper presents a simple but effective method, intended for u... Read More about Restoring river connectivity: Prioritizing passage improvements for diadromous fishes and lampreys.

Prioritising eel-migration barriers for passage improvements (2011)
Presentation / Conference Contribution
Noble, R., Nunn, A., Harvey, J., & Cowx, I. (2009, April). Prioritising eel-migration barriers for passage improvements. Presented at Institute of Fisheries Management 2009 Eel Conference, Bridgwater, Somerset

Physical barriers are becoming increasingly recognised as major factors influencing the migrations, population structures, spawning success and recruitment of freshwater organisms. A high-profile example is that of the European eel, which has recentl... Read More about Prioritising eel-migration barriers for passage improvements.

Knowledge of the foraging ecology of fishes is fundamental both to understanding the processes that function at the individual, population and community levels, and for the management and conservation of their populations and habitats. Furthermore, t... Read More about The foraging ecology of larval and juvenile fishes.
