Small Eye Golden-line Fish: Gathering Data for Effective Conservation

Mainland China has the highest diversity of cavefi shes compared
to other countries and regions. About 150 species have been
discovered, all of which are considered as endemic species
in Mainland China. Due to rapid economic development, their
habitats have been severely destroyed by human activity such as
the use of underground water, leading to changes in the hydrology
of the cave habitat, and the discharge of contaminants that
damage the water quality. These factors pose a serious threat to
the cavefi shes in Mainland China. Therefore, urgent conservation
is needed. The small eye golden-line fi sh is considered a potential
umbrella species, which means that other cavefishes can be
protected indirectly if this species is well-protected. However,
information on this species, such as its spatial distribution and
population status, is scarce, which hampers effective conservation.
A thorough study is needed to review its conservation status and
help formulate conservation measures.
