Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 652-668, June 2022., 2022 Abstract Chronic exposure to high biofloc total suspended solids (TSS) could affect growth, red blood cells, and generate gill alterations in fish. Red pacu, Piaractus brachypomus, fry (2.7 ± 0.5 g weight) were exposed to different biofloc TSS concentrations with low (T1: 200–300), and medium (T2: 400–600 mg/L) levels and compared to a treatment ...

Redox profile in liver of Leporinus macrocephalus exposed to different dissolved oxygen levels [PDF]
Fish Physiology and Biochemistry, 2011 Aquatic organisms are continuously exposed to environmental variations, which can lead to physiological and biochemical alterations. Leporinus macrocephalus, known as piavuçu, is a migratory species that may be exposed to variations in dissolved oxygen levels. Studies evaluating oxidative changes undergone by this species in these conditions are scarce.
