Hematological and immune changes in Piaractus mesopotamicus in the sepsis induced by Aeromonas hydrophila

Fish & Shellfish Immunology, 2019
The pathogenesis of sepsis involves complex systems and multiple interrelationships between the host and pathogen producing high mortality rates in various animal species. In this study, hematological disturbances, innate immunity and survival during the septic process in Piaractus mesopotamicus inoculated with Aeromonas hydrophila were studied.

The administration of exogenous prostaglandin may improve ovulation in pacu (Piaractus mesopotamicus)

Theriogenology, 2012
Based on the reports of unsuccessful ovulation in pacu (Piaractus mesopotamicus) by fish farmers and researchers undertaking artificial reproduction programs, we evaluated the use of prostaglandin F (PGF) to improve pacu ovulation. This study was conducted during two spawning seasons (2009/2010 and 2010/2011) with two samplings in the first season and ...
