Annually, the river basin of Ky Cung – Bang Giang provide important fisheries
to the people of Lang Son and Cao Bang, provides the main source of protein from
fish in the daily meals in each family. Though, So far no work has systematically
studied the fish fauna here. Besides that, the conservation of rare genetic resources
and biodiversity in the Bang Giang – Ky Cung River is a common concern of all
levels and sectors. However, in recent decades the Bang Giang – Ky Cung River has
been subjected to the strong influence of socio-economic activities: mineral
exploitation, domestic waste, industrial activities, increased use of chemical
fertilizers, pesticides polluting water resources, affecting the lives of fish and aquatic
species. Many species of economic value, rare species are rapidly reduced in the
number of strains, reducing biodiversity. Therefore, research into biodiversity
resources of fish species, assess the status of exploitation and adverse activities on
fish resources, contributing to the development of scientific basis for proposing
solutions to protect, use rational and sustainable development of fish resources of the
system. The Bang Giang – Ky Cung river system is urgent. On that basis, contributing
to the education and construction of animals in the country. Provide updated data, the
latest species composition, distribution characteristics, the status of resources, species
need conservation, so that local authorities refer to the development of biodiversity
protection plan. In general, fish in particular contribute to the overall development of
the locality.
Stemming from the above reasons, I chose the project “Research on the fish
fauna of the Bang Giang – Ky Cung river basin in Vietnam
