Genetic Structure and Conservation Strategies for the Endangered Catfish Steindachneridion melanodermatum (Siluriformes, Pimelodidae) in the Iguaçu River, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu

Bile acids as potential pheromones in pintado catfish Pseudoplatystoma corruscans (Spix & Agassiz, 1829): eletrophysiological and behavioral studies

Neotropical Ichthyology
Bile acids are potent olfactory and gustatory stimulants for fish. Electro-olfactogram recording was used to test whether the olfactory epithelium of pintado catfish Pseudoplatystoma corruscans is specifically sensitive to bile acids, some of which have ...

Dietary Probiotics Improve Growth, Immunity and Disease Resistance in Fish Against Aeromonas hydrophila Infection

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Probiotics offer a promising alternative to antibiotics for managing Aeromonas hydrophila infections in aquaculture. Dietary supplementation of probiotics increases fish health, growth performance, and immune responses, while reducing antibiotic reliance in fish farming.

Listeria monocytogenes and Pseudomonas spp. Distribution in a Processing Facility of Spotted Sorubim (Pseudoplatystoma corruscans) in Brazil

Journal of Food Protection, 2022
The ecology of Listeria monocytogenes and Pseudomonas spp. during the slaughtering of spotted sorubim (Pseudoplatystoma corruscans) in a fish processing facility was assessed. Fish samples (n = 28) were obtained in different points of slaughtering (A, arrival; B, washing; C, gutting; and D, cooling) and subjected to detection of L.

First Records of Length–Weight Relationships for Ten Fish Species From the Middle Stretch of the Uruguay River, Southern Brazil

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
This study estimated the length–weight relationships (LWRs) of 10 fish species from the middle stretch of the Middle Uruguay River basin, aiming to provide new morphometric data and contribute to the knowledge of Neotropical ichthyofauna. Fish were collected at seven sites with sampling conducted at each site during every season, totaling 84 sampling ...
