Adhesive eggs, 1.1 to 1.4 mm in diameter, were found attached to stems or leaves of aquatic macrophytes. Larvae hatched at 4.9 mm total length and had between 22 and 26 preanal and 17 to 20 postanal myomeres. In these characteristics, the bigscale logperch resembles other members of the darter subgenus Percina. Aspects of the early life history are summarized and compared with literature accounts of other sympatric percid speciesBIOLOGYjuvenileLAKELARVAELIFE-HISTORYMACROPHYTESriverRIVERSTEXASTrinity RiverTXJournal
