Mendes, YA, JT Lee, IKS Viana, RM Rocha & MAP Ferreira, 2018. Reproductive biology of the tiger pleco Panaqolus tankei (Loricariidae) in a lentic system of the Amazon basin. Journal of Fish Biology doi: 10.1111/jfb.13735.
Abstract
This study presents the first information on the reproduction of the recently described tiger pleco Panaqolus tankei, from Lake Bolonha in the north‐eastern Amazon Basin. This loricariid has a long reproductive period, fractionated spawning and low fecundity (on average, female gonads contained 37 oocytes), a total length (LT) at first maturity of 47.4 mm for females and 54.1 mm LT for males. Correlation of the condition factor and gonado‐somatic index with environmental variables suggests that turbidity favours P. tankei reproduction in this environment.
