The Mutuca stream is the left blank tributary of the Velhas River, located in Nova Lima, Minas Gerais, Brazil. This elevated area is in a protected area by The Sanitation Company of Minas Gerais (COPASA). Its headwaters are in the “Espinhaço” Complex, an area considered by UNESCO as a biosphere heritage reserve. Harttia novalimensis is a catfish species endemic to sub-basin of the “Velhas” River and is considered vulnerable (VU) in the Minas Gerais state list. The specimens were collected bimonthly from October 2008 to August 2009, and to capture the specimens we used screens and mosquito screen drags. We calculated the parameters abundance of population about both species in the higher dry season. The length classes were most abundance among individuals of intermediate size. The length-weight relationship showed that there was negative allometric growth Pareiorhina rosai. and isometric in Harttia novalimensis.
