Summary: The study identified the parasitic infection of R. rondoni nematode in farmed red-bellied pacu in the Peruvian Amazon, causing histopathological alterations in the intestinal tissue. These alterations include villi fusion, edema, and disorganization of epithelial cells. The findings highlight the importance of improving parasitic prevention and control strategies to prevent future disease outbreaks.

Summary: The rise in fish demand in India is due to population growth, increasing affluence, and changing dietary habits. Diversification of aquaculture species, such as the successful introduction of the red-bellied pacu, has led to increased profitability for farmers.

Summary: This study describes the initial development of the red-bellied pacu fish, focusing on its morphological, meristic, and morphometric characteristics. The results show that the most significant changes in P. brachypomus occur during the transition from the flexion stage to the juvenile period, indicating changes in behavior, foraging, and physiology.

Summary: This study characterizes the neurogranin gene in Colombian red-bellied pacu fish and investigates its expression in brain injury and sublethal toxicity. The findings demonstrate differential expression of NRGN under different experimental conditions, suggesting its potential as a biomarker in the fish brain.

Summary: This study characterizes the HAMP1 gene and its expression in different tissues, as well as its regulation in brain injury and organophosphate exposure in Piaractus brachypomus. The study suggests that the HAMP1 gene may be involved in inflammatory, antimicrobial, hypoxia and oxidative stress response.

Summary: This study demonstrated that concentrations of 50-100 mg L-1 of eugenol and 25-100 mg L-1 of menthol are able to induce deep anesthesia in juvenile Piaractus brachypomus. These concentrations had minimal impact on blood parameters.

Summary: This study reports hirudiniasis caused by Hemiclepsis marginata asiatica in albino red-bellied pacu for the first time in India. Infested fish showed symptoms such as asphyxiation, inability to swim, cloudy eyes, and thick mucus secretion. Histopathological analysis revealed degenerative necrosis, eosinophilic infiltration, and hemorrhages in the affected fish.

Summary: The study focused on the preparation, purification, and identification of novel antioxidant peptides from Piaractus brachypomus fish meat. The RPMPH-IF fraction, obtained by ultrafiltration, displayed significantly higher antioxidant activities. After purification by gel filtration and reversed-phase liquid chromatography, the RPH-8 fraction showed the highest antioxidant activities. The peptide sequences of RPH-8 fraction were identified using LC-MS/MS and MASCOT software.

Summary: Piaractus brachypomus is a valuable aquaculture and ornamental fish species, but often considered as a non-native or invasive species. This study provides a detailed taxonomic description and discriminative features of P. brachypomus specimens from Poland, using measurements, dentition, parasite fauna, and mitochondrial COI sequence. The study also reveals the phylogenetic relationship and suggests that morphometric characters may not be suitable for distinguishing closely related species within the genus Piaractus.

Summary: This study genetically characterized Piaractus brevipsomus and Piaractus orinoquensis, two species of migratory fishes, and found that they have moderate genetic diversity and varied patterns of genetic distribution in the fluvial landscape. The effective sizes of local populations of Piaractus brevipsomus were smaller compared to Piaractus orinoquensis. These results suggest the need for management policies that focus on species and geographically restricted populations.

Summary: This study provides the first assessment of the parasitic fauna of farmed Colossoma macropomum in the state of Acre, Brazil. Four monogenean species were identified, with Anacanthorus spathulatus being the most prevalent. These findings are important for future research on the impact of environmental factors on parasite-host relationships.

Summary: This study molecularly characterized the mbpa gene from the Colombian native fish, red-bellied pacu. The results revealed that mbpa belongs to the myelin basic protein family and is closely related to orthologous proteins. Gene expression of mbpa was upregulated in response to sublethal chlorpyrifos exposure.

Summary: This study reports the full open reading frame of the HMGB1a gene from Piaractus brachypomus and characterizes its molecular features, including tissue gene expression. The results show differential expression of HMGB1a in brain regions, with higher expression in the cerebellum and telencephalon. Upregulation of HMGB1a was also observed in sublethal exposure to chlorpyrifos and traumatic brain injury model. These findings suggest a potential role for HMGB1a as a biomarker for brain injury.
