Length-weight (LWR) and length-length (LLR) relationships of seven loach species (Teleostei: Cypriniformes): Botia striata, Lepidocephalichthys thermalis, Paracanthocobitis mooreh, Indoreonectes evezardi, Nemacheilus anguilla, Nemachilichthys rueppelli and Schistura denisoni were studied from five localities within the Krishna River system of the Indian Western Ghats: Lonawala (Indrayani River), Paud (Mula River), Warje (Mutha River), Bhor (Nira River) and Patan (Koyna River).  With the exception of L. thermalis all species are endemic to peninsular India, and to our knowledge this is the first presentation of LWR and LLR data for them.  New maximum lengths are also reported for I. evezardi, N. anguilla, N. rueppelli and S. denisoni.
