Abstract:
Abstract. The Iporanga blind catfish, Pimelodella kronei, from the Alto Ribeira karst area, was the first
troglobite discovered and described in Brazil, and it is still one of the most intensively studied. These
catfish were collected during the 1970´s, causing a population decline recorded by E.Trajano ten years
later. We present data on the population dynamics in the Areias de Cima Cave gathered two decades
after, focusing on distribution of length and condition factor, movements and individual growth, based
on a mark-recapture program carried out from October 2008 to May 2010. These data are compared to
those by Pavan (1945) and Trajano (1987). This is the first long-term monitoring for Brazilian cave fishes.
