Worldwide, fish stocking has been implemented as a key tool in recreational fishery management for many decades. Stocking programs have been developed for a variety of reasons: to create new fisheries or enhance existing ones, to contribute to conservation and recovery initiatives for native sport species and as compensation where major development has eliminated or significantly reduced natural production. The potential benefits are significant. Stocked systems can provide quality angling opportunities where none may otherwise exist, resulting in a variety of social and economic benefits. Stocked systems can reduce the angling pressure on non-enhanced sport fish populations. However, increasing evidence indicates that fish stocking can also have significant detrimental effects on native species and ecosystems. A balance must be established to ensure that stocking for recreational angling purposes does not undermine conservation efforts to protect native biodiversity. This session explores different applications of fish stocking to support recreational fisheries for both marine and freshwater situations around the world.
