Parasitological assessment in hybrids Serrasalmidae fish farmed in Brazil [PDF]

open access: yesRevista Brasileira de Parasitologia Veterinária, 2020
This study evaluated the parasitic fauna of hybrids tambacu (Colossoma macropomum × Piaractus mesopotamicus) and patinga (P. mesopotamicus × Piaractus brachypomus) and their host-parasite-environment interaction during the warm and cold seasons in two ...

Two complete mitochondrial genomes of Myloplus rubripinnis and Metynnis hypsauchen (Characiforme: Serrasalmidae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2019
Myloplus rubripinnis and Metynnis hypsauchen are two compressed-bodied ornamental fishes of Serrasalmidae family. In this study, complete mitochondrial genome sequences of the two species were determined.

Genomic Insights Into Carnivorous Fish in the Characiformes. [PDF]

open access: yesEcol Evol
This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...

Ultrastructure of sonic muscles of piranhas (Serrasalmidae) [PDF]

open access: yesJournal of Morphology, 2022
Abstract Among piranhas, different species are able to produce sounds but not all of them use the same mechanism. In all species, the sound‐producing muscle originates on the second vertebra, but the insertion differs.

Molecular characterization of Serrasalmidae hybrid in the upper Paraná River floodplain using molecular markers. [PDF]

open access: yesJ Fish Biol
Abstract This study reports the molecular identification of a tambacu—a hybrid of Colossoma macropomum and Piaractus mesopotamicus—in the floodplain of the upper Paraná River using molecular markers. The PCR‐GEL method, based on the analysis of COI and TROP fragments, successfully characterized the hybrid, while PCR‐SEQ, employing RAG2 and TROP markers,

Weight-Length Ratio of Piranhas <i>Serrasalmus</i> (Characiformes, Serrasalmidae) in Bolivia: Relationships to Molecular Divergence and Maximum Size? [PDF]

open access: yesEcol Evol
This study presents WLRs of nine piranha or palometa fish species of genus Serrasalmus present in the Amazon and La Plata basins of Bolivia and compares differences with genetic divergence (mtDNA COI locus) and the observed maximum size. All species showed an exponential (power type) growth pattern, and all WLRs were significantly different among all ...

Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes. [PDF]

open access: yesEcol Evol
Otophysan fishes represent 70% of living freshwater fishes with 12,000 species. Relationships among their four orders were explored through a dense taxonomic sampling including 529 complete mitochondrial genomes and 4 nuclear genes for 324 species.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]

open access: yesConserv Biol
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Characterization of Mitochondrial Genomes and Evolutionary Relationships in Two <i>Moenkhausia</i> (Characiformes: Acestrorhamphidae). [PDF]

open access: yesEcol Evol
This study successfully decoded the complete mitochondrial genomes of two Moenkhausia species, with total lengths of 16,439 and 16,461 bp, respectively. This study enhances genomic resources for Acestrorhamphidae and provides a foundation for investigating evolutionary mechanisms and developing molecular markers.
