Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

A new catfish species of Microcambeva Costa & Bockmann, 1994 (Siluriformes: Trichomycteridae) from southern Brazil, with a redescription of M. ribeirae Costa, Lima & Bizerril, 2004

Journal of Fish Biology, EarlyView.
Abstract Among the few species of Microcambeva reported as occurring in more than one hydrographic basin, M. ribeirae has been previously listed from both the Ribeira de Iguape and the Guaraqueçaba basins. However, morphological and molecular analyses revealed that the specimens from Guaraqueçaba represent a new species, which is described in this ...

Aspects of the Histopathology of Clarias gariepinus Infected With the Camallanid Parasite Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015

Journal of Fish Diseases, EarlyView.
ABSTRACT Histopathological studies of infections with the nematode Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015, an intestinal parasite of Clarias gariepinus (Burchell, 1822), are scarce. The current study describes histopathological changes in the stomach of C. gariepinus infected with P.

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Pharmacokinetics, Optimal Dosages, and Withdrawal Time of Florfenicol in Cobia (Rachycentron canadum) After Oral Administration via Medicated Feed

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Antimicrobial drugs are commonly used for the treatment of bacterial diseases in cobia (Rachycentron canadum), but information regarding the rationale of their therapeutic use, such as pharmacokinetics (PK), optimal dosages, and withdrawal time (WDT) in this species is very rare.

Performance and Health Status of Juvenile Largemouth Bass (Micropterus nigricans) Fed Inclusions of Enzyme‐Treated and Low‐Oligosaccharide Soy Proteins

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Plant‐based proteins, such as soybean meal (SBM), have shown promising results in cultured species but also present challenges due to their nutrient composition and inherent antinutritional factors. This study investigated how the replacement of solvent‐extracted SBM with low oligosaccharide soybean meal (LSBM) or enzyme‐treated soybean meal ...
