Aquaculture has recently developed especially with villagers. Serious concerns have emerged about the environment impact of both tourism and aquaculture in Ha Long Bay.
Presentation
The initial data was presented on behalf of IndoChina Junk at the World Aquaculture Society conference Praha 2012
At the UNESCO World Heritage site of Ha Long Bay, the floating villages began aquaculture enterprises 10 years ago. Various species are cultured, and the predominant methodology is cage culture with trash fish as feed. Well known negative environmental impacts are associated with the use of ‘trash fish’ including inconsistent supply and quality, removal of feed fish upon which higher trophic level wild fish populations depend, as well as increased incidence of pathogen transfer.
