Dr Jonathan D. Bolland

Fisheries scientist specialising in the factors affecting the dispersal of freshwater fish; the social, economic and ecological aspects of recreational fishing; genetically modified fish; and the conservation and management of important fish, pearl mussel and lamprey species, as outlined below:

 i) The effects and importance of floods and high flow events on species dynamics and fish populationsover the rivers entire course, but with particular emphasis placedupon the importance oflateral connectivity for both juvenile and adult fish and the necessity for lowland river rehabilitation. Sampling included using fixed location sonar (DIDSON).

ii) The movement and habitat use of both wild and stocked sub-adult cyprinids using radio tracking, mark-recapture and PIT telemetry, with particular emphasis on the influence of temperature and flow, including flood events.

iii) The tensions that arise in terms of the social, economic and ecological ‘sustainability’ of stillwater recreational angling, particularly the relationship between ecology and human well being in the context of a multifunctional countryside. Ecological emphasis was placed upon catchment scale analyses of stillwater distribution, origin, size, water supply and fish species composition, including stock enhancement of both native and non-native species.

iv) Defining environmental risk assessment criteria for genetically modified fishes to be placed on the EU market.

v) Development of environmentally sound guidelines for stocking hatchery reared juvenile freshwater pearl mussels.

vi) Determination of the condition status of salmon, shad, lampreys and bullhead populations, often associated with numerous anthropogenic impacts, including habitat degradation, flow regulation (run-of-river hydropower and reservoir compensation releases), channelization and pollution.
