Relationships between ovarian structure, oocyte structure/development, and parental care/life history strategies of six loricariid catfishes common in the upper Paraná River, Brazil were examined with analysis of catch data, relative gonad weight, histology, and microscopy. Three life history strategies were observed. Loricariichthys platymetopon, Loricariichthys sp. and Loricaria sp. produce several small clutches of large eggs over a protracted spawning period. Males of these species guard… CONTINUE READING
