Inland Fisheries

The current high demand for fish and increased awareness of the
role of the environment in supporting human well being has led to a
situation where attitudes to inland water resources are changing
rapidly.

Trends in resource use and environmental impact are very evident
in inland waters which are particularly vulnerable as they act as
collectors of all the activities occurring in their basins and rank
as some of the most endangered ecosystems in the world. The
principle changes influencing the evolution of the aquatic resource
for fisheries are described in this book, which has been compiled
for the Food and Agriculture Organization of the United
Nations.

Zusammenfassung
The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly. Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.
