Ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermiogenesis

, 2000
The spermiogenesis and the spermatozoon ultrastructure of Sorubim lima were studied. Our observations showed that early spermatids are round-shaped cells, have spherical nucleus with diffuse chromatin, small quantity of mitochondria and large amount of ...

Age and growth of the Duckbill Catfish (Sorubim cf. lima) in the Pantanal

Brazilian Journal of Biology
The Duckbill Catfish, Sorubim lima, is a predator of large South American rivers. The age and growth of S. lima were studied based on the pectoral fin-spines of samples collected from the Cuiabá River, Pantanal. The samples were taken from commercial and

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Length‒Weight and Length‒Length Relationships of Freshwater Fish Species Caught by Professional Fishermen in the Itaipu Reservoir, Brazil

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Length‒weight relationships (LWRs) and length‒length relationships (LLRs) were estimated for 63 and 58 freshwater fish species, respectively, captured in the Itaipu Reservoir, Paraná River Basin, Paraná State, Brazil. Sampling was carried out from March 1987 to July 2024 at 63 professional fishing sites within the reservoir’s area of influence ...

River Geomorphology and Fish Diversity Around the Manseriche Gorge, the Last Andean Crossing Is in Peril

Water Resources Research, Volume 60, Issue 11, November 2024.
Abstract The transition from the Andes to the Amazon lowland hosts a high biodiversity and currently is facing several anthropogenic activities, including hydropower infrastructure projects. Little is known about the geomorphology of the Andean gorges, rivers and the interaction with the fish diversity upstream and downstream of gorges.

Assessing fish diversity in abandoned mining ponds in Madre de Dios, Peru, using environmental DNA

Environmental DNA, Volume 6, Issue 1, January–February 2024.
We surveyed four lentic systems in Madre de Dios, Peru: two abandoned mining ponds created by ASGM and two unmined oxbow lakes as a reference to assess fish recolonization. We compared two alternative eDNA processing methods and contrasted our results with historic data from traditional biodiversity monitoring. Our results indicate that eDNA could be a

Karyotype variability in neotropical catfishes of the family Pimelodidae (Teleostei: Siluriformes)

Neotropical Ichthyology, 2011
Karyotypic data are presented for four species of fish belonging to the Pimelodidae family. These species show a conserved diploid number, 2n = 56 chromosomes, with different karyotypic formulae.

Analysis of Migratory Catfish Production from Artisanal Fishing in the Middle Madeira Sub‐Basin Using New Monitoring Methods, Southwestern Amazon

Journal of Applied Ichthyology, Volume 2024, Issue 1, 2024.
Studies on the production of Pimelodidae catfish in the Amazon are generally carried out in large fishing centers. However, the data referring to small‐scale fisheries have gaps that can represent a risk to the activity. This study evaluated the volume produced and the revenue obtained from migratory catfish of the Pimelodidae family of commercial ...
