The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species

Neotropical Ichthyology
Reared fish differ from wild fish in several aspects, including morphology, because they are adapted to captive conditions that are totally different from natural conditions. To minimize the influence of the hatchery environment on the morphology of fish,

Una contribución al estudio del Pirapita (Brycon Orbignyanus) [PDF]

Revista del Museo de La Plata, 1949
Diversos autores que estudiaron los peces de agua dulce de la cuenca del Río de la Plata han señalado reiteradamente la presencia de varias especies del género Brycon. El profesor Dr. Emiliano J. Mac Donagh me sugirió aclarar ese problema bajo su dirección y le agradezco la dedicación que me ha prestado. Efectué esta investigación, completándola con un
