Probiotic actions of Bacillus cereus var. toyoi and Saccharomyces boulardii in silver catfish (Rhamdia quelen) larvae culture

Revista Brasileira de Zootecnia, 2012
The objective of this study was to evaluate the use of Bacillus cereus var. toyoi and Saccharomyces boulardii as probiotics to improve Rhamdia quelen culture. Six hundred larvaes (0.16±0.07 g) were divided in three replicate tanks (25-L recirculation, 20

Cephalic Musculature of the Pacman Catfish Lophiosilurus alexandri Steindachner, 1876 (Siluriformes, Pseudopimelodidae)

Journal of Morphology, Volume 286, Issue 5, May 2025.
The head of the Pacman catfish (Lophiosilurus alexandri [L. alexandri]) is strongly depressed, broad, and with a large mouth, roughly resembling those of Lophius piscatorius and Chaca bankanensis. Also, they are bottom dwellers and have ambush behavior for fish predation.

Effects of Environmentally Relevant Concentrations of Roundup on Oxidative‐Nitrative Stress, Cellular Apoptosis, Prooxidant‐Antioxidant Homeostasis, Renin and CYP1A Expressions in Goldfish: Molecular Mechanisms Underlying Kidney Damage During Roundup Exposure

Environmental Toxicology, Volume 40, Issue 5, Page 817-834, May 2025.
ABSTRACT Roundup is one of the most widely used glyphosate‐based harmful herbicides in the United States as well as globally, which poses a severe risk for terrestrial and aquatic organisms. In order to identify the detrimental effects of Roundup exposure in aquatic organisms, we investigated the environmentally relevant concentrations of Roundup ...

Metabolic growth differences between Gymnocypris przewalskii and Gymnocypris eckloni: A quantitative proteomic perspective

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Metabolism plays a crucial role in the growth rate of species. Proteomics serves as a potent tool to explore these metabolic changes. Herein, we investigated the metabolic growth differences in Gymnocypris przewalskii (GP) and Gymnocypris ecklon (GE). After 9 months of culture, the growth rate of GP was slower than that of GE (p < 0.05), while
