Les données piscicoles dans les études d'impact des aménagements hydroélectriques
Fish data in impact studies of hydropower devices
Conseil Supérieur de la Pêche
The studies of impact related to projects of small hydropower stations should have, considering seasonal and climatic variations, incidences on aquatic environments and especially on fish population.
The making-up of actual fish situation need a good identification of the concerned area by the impact (direct and indirect impact). Protocols of data acquisition in line with the instructor service need to be defined too.
The expectation of the impact on the fish population involves to know sufficiently different compartments of aquatic ecosystem and their foreseable evolution. The expectation of the impact is articulated around biological requirements of principal species:
- reproduction-hatching phase,
- free migration of fishes.
