SOME HISTOLOGICAL AND ULTRASTRUCTURAL ASPECTS OF OOGENESIS IN Piaractus mesopotamicus HOLMBERG, 1887 (TELEOSTEI)
This paper describes various aspects of oogenesis in Piaractus mesopotamicus (pacu), particularly the changes in nuclear morphology and the nuclear-cytoplasmic interactions during the early developmental stages of oocytes. Material produced in the nucleus and passed to the cytoplasm, known as “nuage”, was observed in oogonia and in oocytes. In the oocyte cytoplasm, this material gives rise to g...
متن کاملStructural and morphological features of Piaractus mesopotamicus (Holmberg, 1887) gills.
The pacu Piaractus mesopotamicus (Holmberg, 1887), is a commercially important serrasalmid fish endemic to the Paraná-Paraguay River basin, and one of the most widely cultivated native fish species in the Neotropics. As a migratory species, also inhabiting temporary pools subjected to hypoxic conditions, the species presents a high plasticity concerning respiratory adaptations. In order to supp...
متن کاملMorphological study of the spermatogenesis in the teleost Piaractus mesopotamicus.
The spermatogenesis of Piaractus mesopotamicus was investigated under light and transmission electron microscopy. The specimens were captured from their natural environment (Rio Miranda and Rio Aquidauana, Pantanal Matogrossense, Brazil) during April and September. The results were compared with the spermatogenic data of specimens under captivity condition. In both conditions, P. mesopotamicus ...
متن کاملAeromonas hydrophila sepsis in a preterm neonate.
A female infant was born at 27 weeks of gestation by spontaneous vaginal delivery at home in the toilet. She was retrieved, resuscitated, commenced on intravenous antibiotics and ionotropic support. She was transferred to our level 3 neonatal intensive care unit at 8 hours of age. She received 2 doses of Curosurf® for hyaline membrane disease. Inotropes were weaned and she was extubated to CPAP...
متن کاملParasitic infections of Piaractus mesopotamicus and hybrid (P. mesopotamicus x Piaractus brachypomus) cultured in Brazil.
This study evaluated the occurrence of parasitic infections in the "pacu" fish Piaractus mesopotamicus and the "patinga" hybrid (P. mesopotamicus x Piaractus brachypomus) in the northwest of São Paulo State, Brazil. Fish from the following three fish farms were evaluated every two months: A, a hatchery and larviculture farm (n = 16 pacu / n = 19 patinga), B, a growout farm (n = 35 patinga) and ...
