First record of the mating behaviour of the spotted surubim Pseudoplatystoma corruscans in the Uruguay River

Journal of Fish Biology, 2020
AbstractThe spotted surubim Pseudoplatystoma corruscans is a large migratory catfish native to the La Plata and San Francisco basins. Nonetheless, its reproductive dynamics and behaviour remain poorly understood. This brief note provides the first record of the mating behaviour of P. corruscans in natural conditions.

Testicular differentiation and development in South American catfish, surubim, Pseudoplatystoma fasciatum

Journal of Applied Ichthyology, 2019
In the species Pseudoplatystoma fasciatum the males are smaller than females. Thus, the objective of this study was to describe the process of testicular differentiation and provide tools for sex manipulation techniques aimed at improving the productivity of farming of sexually‐reversed females.

Migration and spawning of female surubim (Pseudoplatystoma corruscans, Pimelodidae) in the São Francisco river, Brazil

Environmental Biology of Fishes, 2006
Surubim, Pseudoplatystoma corruscans, is the most valuable commercial and recreational fish in the Sao Francisco River, but little is known about adult migration and spawning. Movements of 24 females (9.5–29.0 kg), which were radio-tagged just downstream of Tres Marias Dam (TMD) at river kilometer 2,109 and at Pirapora Rapids (PR) 129 km downstream of ...

Oocytes of The Endangered Gray Catfish (Surubim-Do-Paraiba) Submitted to Different Conservation Protocols.

Cryo letters, 2021
The gray catfish known as Surubim-do-Paraíba (Steindachneridion parahybae), which is endemic to the Paraíba do Sul river basin, is on the red list of Brazilian fauna threatened with extinction and the cryopreservation of germ cells of this fish is needed in support of conservation.We aimed to assess the effect of storage temperature on S.
