Chromosome Study of Slender Walking Catfish (Clarias nieuhofii) andAfrican Catfish (C. gariepinus) F1 Hybrid: Revealed by Conventional Staining and Ag-NOR Banding Techniques

open access: yesScience Technology and Engineering Journal (STEJ), 2021
The hybrid catfishes Clarias nieuhofii (♀) × C. gariepinus(♂) were cytogenetically studied using conventional staining and Ag-NOR banding techniques, with the aim to reveal the chromosome complement and chromosome marker of the hybrid.

Comparative Ecotoxicological Assessment of Acetaminophen and Diclofenac using Freshwater African Catfish Clarias gariepinus (Burchell 1822)

open access: yesJournal of Applied Sciences and Environmental Management, 2018
The use and abuse of analgesics, commonly referred to as painkillers is on the rise globally. This study examined the acute toxicity and sub-lethal effects on liver function (ALT, AST, ALP) and anti-oxidative stress enzymes of the African Catfish ...

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

open access: yesAnimal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Unrevealing Parasitic Trophic Interactions—A Molecular Approach for Fluid-Feeding Fishes

open access: yesFrontiers in Ecology and Evolution, 2018
Fish diets have been traditionally studied through the direct visual identification of food items found in their stomachs. Stomach contents of Vandeliinae and Stegophilinae (family Trichomycteridae) parasite catfishes, however, cannot be identified by ...

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

open access: yesAnimal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Mitochondrial phylogeny and phylogeography of East African squeaker catfishes (Siluriformes: Synodontis)

open access: yesBMC Evolutionary Biology, 2006
Background Squeaker catfishes (Pisces, Mochokidae, Synodontis) are widely distributed throughout Africa and inhabit a biogeographic range similar to that of the exceptionally diverse cichlid fishes, including the three East African Great Lakes and their ...

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Haematozoa of wild catfishes in northern Australia

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2018
Very little is known about the diversity, prevalence, or pathogenicity of haematozoa in Australian freshwater fishes. Blood smears from 189 native catfishes, of six different species, from northern Australia were examined for haematozoa.

Recent Perspectives on Phytochemical Profile, Pharmacological Activities, and Industrial Applications of Guava (Psidium guajava)

open access: yesFood Safety and Health, EarlyView.
Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.
