Phytic acid in Rhamdia quelen nutrition: Antioxidant or antinutrient?

Animal Feed Science and Technology, 2021
Abstract The study aimed to evaluate phytic acid supplementation at different levels in diets for juveniles of silver catfish (Rhamdia quelen). Five isonitrogenous and isolipidic diets were prepared with different phytic acid concentrations (0; 5.00; 10.00; 15.00 and 20.00 g/kg).

Assessment of oxidative stress in Rhamdia quelen exposed to agrichemicals

Chemosphere, 2010
Due to the proximity of crop and fish culture areas, some agrichemicals that could be harmful for fish could enter into fishponds by different ways, such as by leaching through rain. Rhamdia quelen (Teleostei) were exposed to sublethal concentrations of methyl parathion (MP), a glyphosate based herbicide (Gly), and tebuconazole (Teb).

β-Glucan improves wound healing in silver catfish (Rhamdia quelen)

Fish & Shellfish Immunology, 2019
The immune modulating activity of β-glucan on aquatic species has been a matter of intense investigation. Here, we aimed to investigate the effect of β-glucan on wound healing of silver catfish, a Neotropical South American scale-free fish. Small sections of skin and muscle (3 mm in diameter) were removed and fish were bathed daily with β-glucan (0.1 ...

Intraspecific chromosome analysis in Rhamdia quelen (Siluriformes, Heptapteridae)

2010
We studied the chromosomes of Rhamdia quelen. All specimens presented 2n = 58 and 36m+16sm+6st and FN = 116 and showed metacentric B chromosomes of medium size. The specimens from Água dos Patos river, Água das Pedras river and fish farm station showed a secondary constriction in the short arm of pair 28 (st), coincident with the NOR, while in the ...

Nociceptive-like behavior and analgesia in silver catfish (Rhamdia quelen)

Physiology & Behavior, 2019
Fish are useful animal models in research and have been employed in developing new pharmacological approaches. This study aimed to establish the use of silver catfish (Rhamdia quelen) as an animal model to evaluate antinociceptive activity. Initially, different concentrations of acetic acid (2.5-20%), formalin 1% (1-10 μL), menthol 0.5% (1-10 μL) or ...

Hematologic and serum biochemical values for jundiá (Rhamdia quelen)

Fish Physiology and Biochemistry, 2004
The determination of hematologic parameters for jundia Rhamdia quelencultivated in ponds is an easy and useful tool for the control of their sanitary and nutritional conditions. In the present work hematologic indices (RBC, WBC, Ht, Hb, MCV, MCH, MCHC), electrolytes (Cl, Na, K, Ca, Mg, P), metabolic products (creatinine, urea, ammonia, glucose, total ...

Innate immune response of silver catfish (Rhamdia quelen) exposed to atrazine

Fish & Shellfish Immunology, 2012
The impact of agrichemicals on aquatic vertebrate species has been a matter of increasing concern to researchers and environmentalist. In the present study, we evaluated the effects of a sublethal concentration of atrazine (10% of the LC(50-96 h)), a world-wide used herbicide, on the innate immune system of silver catfish (Rhamdia quelen).

Effects of low concentrations of ibuprofen on freshwater fish Rhamdia quelen

Environmental Toxicology and Pharmacology, 2018
Ibuprofen is a pharmaceutical drug widely used by the global population and it has been found in aquatic ecosystems in several countries. This study evaluated the effects of ibuprofen in environmental concentrations (0, 0.1, 1 and 10 μg/L) on the freshwaterspecies Rhamdia quelen exposed for 14 days.
