title: Biological aspects of amazonian fishes I. Red blood cell phosphates of schooling fishes (genus Semaprochilodus: Prochilodontidae).
abstract: Red blood cell soluble phosphates from Semaprochilodus taeniurus, S. insignis and a possible hybrid jaraqui-açu, from Amazon basin, were studied by column chromatography. The Semaprochilodus school and the jaraqui-açu shows an intermediate percentage of total phosphorus content as GTP but not as ATP. GTP/ATP ratio for jaraqui-açu and S. taeniurus were 1.5 and for S. insignis, 3.0.
