Garra orientalis (Nichols) Distribution. Tai Lam Chung Reservoir, Plover Cove Reservoir (A.C. Lam, pers. comm., 2021). Native range. Asia (presumably East Asia). Remarks. Native riverine populations of this species have not been recorded again since Chan (2001) and are suspected to be extirpated as their local habitat has been channelised. It is unlikely this species naturally occurred in feeder streams of the two reservoirs as it usually inhabits tributaries of large rivers (Pan et al., 1991), which are not present within the catchments of Tai Lam Chung and Plover Cove. The populations in the two reservoirs likely arrived through water transfer from mainland China since this species naturally occurs in the Dongjiang river system (Guangdong and Beijiang rivers) (Pan et al., 1991).
