C. mirianae - Fishing report by Dr. Stuart Willis
We fished these near Alta Floresta in the Teles Pires and its tributary the Rio Azul, and on the Suia Missu in the upper Xingu basin, at Brazil Novo. The Suia Missu is a mid-gradient bowl shaped river (relatively deep and stable, with high banks), with a number of oxbow lagoons.  We found C. mirianae in both the channel and lagoons here.  The Rio Azul, and many smaller upper Xingu tributaries are higher gradient tributaries, and C. mirianae are less common in the main channel than in lagoons. We caught them mostly in floodplain lagoons. Both river systems vary between clear or black water, depending on the surroundings and season.  In both places we caught these on weedless spoons, or on in-line spinnerbaits.
