Abstract The European eel (Anguilla anguilla) is critically endangered (according to the most recent IUCN assessment) and has suffered a 95% decline in recruitment since the 1980s, attributed in part to factors occurring during the marine phases of i

Individual repeatability in the timing of river entry indicates the strong influence of photoperiod in the spawning migrations of iteroparous twaite shad Alosa fallax
Autor: Mark I. A. Yeldham, J. Robert Britton, Charles Crundwell, Peter Davies, Jamie R. Dodd, Andrew D. Nunn, Randolph Velterop, Jonathan D. Bolland
Publikováno v: Hydrobiologia. 850:1619-1634
The timing of entry into freshwater by mature anadromous fishes is an important component of their migration phenology. In iteroparous anadromous species, identifying the migration cues that influence the timing of entry into freshwater, and annual v

Tracking anadromous fish over successive freshwater migrations reveals the influence of tagging effect, previous success, and abiotic factors on upstream passage over barriers

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences.
Predicting and mitigating the impact of anthropogenic barriers on migratory fish requires an understanding of the individual and environmental factors that influence barrier passage. Here, the upstream spawning migrations of iteroparous twaite shad A

Individual movement variation in upstream‐migrating sea lamprey Petromyzon marinus in a highly fragmented river
Autor: Peter Davies, John Robert Britton, Andrew D. Nunn, Jamie R. Dodd, Chris Bainger, Randolph Velterop, Jonathan D. Bolland
Publikováno v: Freshwater Biology. 67:643-656
Anthropogenic reductions in riverine connectivity can severely impede the migrations of anadromous species. In fragmented rivers, successful migrations depend on the ability of migrants to negotiate barriers or locate alternative passage routes. Howe

Novel insights into the marine phase and river fidelity of anadromous twaite shad Alosa fallax in the UK and Ireland
Autor: A. D. Nunn, Ross O'Neill, Thomas Stamp, Niall O'Maoileidigh, Peter Davies, Jonathan D. Bolland, Jamie R. Dodd, Emma V. Sheehan, Charles Crundwell, Randolph Velterop, Robert Britton
© 2020 The Authors. Aquatic Conservation: Marine and Freshwater Ecosystems published by John Wiley & Sons Ltd Most research on anadromous fishes has been invested in their freshwater life-phases, resulting in a relatively sparse understanding of the

Consequences of catch-and-release angling for black bream Spondyliosoma cantharus, during the parental care period: implications for management
Autor: J. Robert Britton, Randolph Velterop, Adrian C. Pinder, Steven J. Cooke
Black sea bream Spondyliosoma cantharus is highly valued for its sporting and eating qualities. Due to its inshore spawning aggregations and male nest guarding behaviors, it is considered vulnerable to over-exploitation via recreational angling. Acco
