The effect of water quality on coarse fish productivity and movement in the Lower River Irwell and Upper Manchester Ship Canal a watercourse recovering from historical pollution

This is the Effect of water quality on coarse fish productivity and movement in the Lower River Irwell and Upper Manchester Ship Canal: a watercourse recovering from historical pollution report produced by the Environment Agency in 2003. The aim of this study was to investigate the impact of water quality upon coarse fish population dynamics in a lowland, urban watercourse. All of the research carried was undertaken in the lower River Irwell and upper Manchester Ship Canal, between February 1998 and December 2001. Of particular interest was the natural sustainability of the urban fishery given recent concern raised in the angling community over an apparent decline in coarse fish populations in lowland rivers. The research described in this report has concentrated upon the role of water quality in determining coarse fish population dynamics, and in particular: The impact of water quality upon fish growth and productivity; The impact of poor water quality and low dissolved oxygen concentrations upon fish distribution and movement; The impact of water quality upon the sexual development of fish.

Proceedings of the International Workshop responding to HIV and AIDS in the fishery sector in Africa, Lusaka, Zambia, 21-22 February 2006

The purpose of the workshop was to enable professionals and organizations working with fishing communities in response to HIV and AIDS in Africa to share experiences, appraise the efficacy of their approaches and identify actions in research and development that will further improve their impact. The workshop pursued and achieved the following objectives: 1)Review and compare research findings and approaches applied in response to HIV and AIDS in fishing communities and the wider fishery sector. 2)Identify good practice examples for wider application. 3)Identify next steps in development and research to scale up these examples. 4)Initiate a network of practitioners in Africa for capacity building, scaling-up and further development of approaches. The range of papers presented at the conference reveals the diversity of responses to HIV and AIDS in the fishery sector at all levels. The papers discussed a range of issues within this broad remit, from community level impacts of disease to policy implementation, from spatial mapping to theatre as a mode of communication.
