EPITHELIOCYSTIS DISEASE IN CULTURED PACU (PIARACTUS MESOPOTAMICUS) IN BRAZIL [PDF]

Acta Veterinaria Hungarica, 1999
Epitheliocystis disease was diagnosed in a cultured pacu (Piaractus mesopotamicusHolmberg, 1893) stock on the basis of gross pathological (greyish-white, pinpoint- or pinhead-sized focal areas, connected strongly to the gill lamellae) and histopathological examinations (hypertrophic cells 10-40 µm in size, having a well-defined wall and a central ...

COMMERCIAL PHYTASE USE IN PACU (Piaractus mesopotamicus)

Boletim do Laboratório de Hidrobiologia, 2023
Phosphorous is one of the most essential nutrients for fi sh. However, an excess of this mineral in fi sh diets in phytate form can lead to higher levels of excreted phosphorous. The phytase enzyme is responsible for the conversion of phytate into organic phosphorous, although it has been suggested that fi sh do not produce this compound, requiring the

Role of neuroendocrine modulation and biochemistry in the sepsis in Piaractus mesopotamicus

General and Comparative Endocrinology, 2020
Sepsis is a systemic process with multifactorial pathophysiology that affects most animal species. It is responsible for high rates of morbidity and mortality. This work aimed to study the biochemical and neuroendocrine changes of the sepsis process in Piaractus mesopotamicus after Aeromonas hydrophila inoculation analyzing changes in blood leukocyte ...
