Rehabilitation of Rivers for Fish: A Study Undertaken by the European Inland Fisheries Advisory Commission of FAOIan G. Cowx, R. L. Welcomme Food & Agriculture Org., 1998 - 260 pagine Value can be added to projects for restoring the aesthetic appeal of modified waterways at very little extra cost if the needs of the living components of the system are taken into account. This manual was prepared by the European Inland Fisheries Advisory Commission (EIFAC) to provide guidelines and techniques for the rehabilitation of rivers for fish. It is intended for the use of fisheries managers, fisheries and wildlife biologists, land and water use planners, and civil engineers working on projects involving the protection and rehabilitation of inland running waters. While the primary orientation of the manual is towards rivers of the temperate zone, the techniques described can be applied to the restoration of rivers of similar dimensions in other climatic areas. |
