High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods

Journal of Fish Biology, EarlyView.
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Immunogenicity and Protective Efficacy of the First Autogenous Aeromonas hydrophila Vaccine for Piaractus brachypomus

Journal of Fish Diseases, EarlyView.
ABSTRACT Aeromonas hydrophila is a major zoonotic bacterial pathogen responsible for haemorrhagic septicemia, substantial economic losses in aquaculture and increasing antimicrobial resistance among field isolates. It is also one of the main bacterial species associated with mortality outbreaks in pirapitinga, Piaractus brachypomus, culture in the ...

Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...
