A newly identified population of Gambusia affinis (Baird and Girard, 1853), a non-native invasive species, in Lake Kenyir, Malaysia: Implications for management (2015)
Journal Article
Walton, S. E., Ahmad, A. B., Gan, H. M., & Bolland, J. D. (2016). A newly identified population of Gambusia affinis (Baird and Girard, 1853), a non-native invasive species, in Lake Kenyir, Malaysia: Implications for management. BioInvasions Records, 5(2), 107-114. https://doi.org/10.3391/bir.2016.5.2.08

Gambusia affinis (Baird and Girard, 1853), a notorious non-native invasive fish species, has negatively impacted aquatic ecosystems around the world. This species was recently identified in Lake Kenyir, one of the largest impoundments in SouTheast As...

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...

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.

Movements and habitat use of wild and stocked juvenile chub, Leuciscus cephalus (L.), in a small lowland river (2008)
Journal Article
Bolland, J., COWX, I. G., & LUCAS, M. C. (2008). Movements and habitat use of wild and stocked juvenile chub, Leuciscus cephalus (L.), in a small lowland river. Fisheries Management and Ecology, 15(5-6), 401-407. https://doi.org/10.1111/j.1365-2400.2008.00631.x

Stocking is a widespread management activity in inland fisheries, but the efficacy of such fishery enhancement measures is poorly understood. Radio-telemetry was used to compare the movements and habitat selection of stocked, juvenile chub, Leuciscus...

Establishment of self-sustaining populations of non-native fish species in the River Trent and Warwickshire Avon, UK, indicated by the presence of 0+ fish (2007)
Journal Article
Nunn, A. D., Bolland, J. D., Harvey, J. P., & Cowx, I. G. (2007). Establishment of self-sustaining populations of non-native fish species in the River Trent and Warwickshire Avon, UK, indicated by the presence of 0+ fish. Aquatic Invasions, 2(3), 190-196. https://doi.org/10.3391/ai.2007.2.3.6

This study investigated the reproduction of non-native fish species, inferred from the presence of 0+ fish, in three English lowland rivers over an 8 year period. Evidence of self-sustaining populations was found for three non-native fish species, na...
