Potential Projects and Areas of Concern
.
The projects and issues listed below have not been prioritised; they represent areas that have been deemed worthy of further investigation by the committee as and when feasibility and funding has been established. Working partnerships with other organisations and agencies would be welcome as would any potential funding partnerships. If you feel in a position to assist please see contacts page.
.
Necessary consents and permissions will be sought when projects are at the requisite stage of planning.
.
To maintain optimum flow at times of low flow in lower river.
Cyprinid friendly fish pass.
To enable migration of adult cyprinids to compensate for flood displaced populations.
Total spawning habitat.
See "Gravel Cleaning Qualities of Natural Obstructions"
Chub predation related to population dynamics.
Trout farm ingress.
Ox bow restoration as flood bays.
Expansion of knowledge related to MSW influences on salmon.
Roach Population Dynamics
Influencing factors
- Endocrine disrupters
- Chemical pollution
- Flood displacement of fry
- Loss of habitat
- Piscine predation of ova and fry
- Avian predation
- Barriers to adult migration
Potential Projects
- Introduction of food signature marked fry to monitor migration and survival
- Provide flood protection bays by clearing blocked Ox-bow Lakes
- Creation of spawning habitat
- Investigate extent of endocrine disruption
- Investigate extent of trout farm ingression
- Desktop study of scientific literature/EA monitoring results/Anglers catch records to quantify and evaluate numeric and geographical extent of decline.
- Comparative physiological/ecological study of areas containing a self sustaining population with areas of declining or failed population.
