Cryogenic preservation of embryos ofProchilodus lineatus(Valenciennes, 1836) (Characiforme; Prochilodontidae) [PDF]

Zygote, 2009
SummaryWhile the freezing techniques of mammal embryos have been providing promising results, the cryopreservation of teleostean eggs and embryos have remained unsuccessful up to now. Therefore, this work aimed to develop a procedure of cryogenic preservation of embryos ofProchilodus lineatusand to observe, at both structural and ultrastructural levels,

Illuminating the Dark: Using eDNA Metabarcoding to Study the Unique Ichthyofauna of the Furnas Formation Sinkholes

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.

Radiotagging a long-distance migratory characid fish: reproduction after surgery, tag losses, and effects in weight

Neotropical Ichthyology, 2021
Although biotelemetry studies bring useful information, tagging is a highly invasive procedure. For this reason, we assess if intracoelomic tagging alters survivorship, weight gain and/or reproductive capacity of a neotropical migratory fish.

Chemical modulation on heterogeneous growth in Prochilodus lineatus (Valenciennes, 1847) (Pisces; Characiformes) [PDF]

Brazilian Journal of Biology, 2007
In the present study, the effect of chemical factors released by conspecifics on growth variability (heterogeneous growth - HetG) in a gregarious fish species (Prochilodus lineatus) was tested. HetG was assessed by the weight variation coefficient in two consecutive 21-day periods.

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...

Role of glucose in enhancing life and potency of Cirrhinus mrigala spermatozoa during cryopreservation [PDF]

, 2015
Cryopreservation of fish gametes is an emerging technology and breeding with cryopreserved gametes is advancement in fish seed production. Success of cryopreservation is evaluated by the post - thaw motility of the spermatozoa, an for which energy is ...

Desempeno del sabalo Prochilodus lineatus en policultivo con pacu Piaractus mesopotamicus

Latin American Journal of Aquatic Research, 2016
In fish farming 30% of the nutrients provided are retained as animal biomass, and the remainder is lost in the sediments. An alternative is to produce in polyculture, to take advantage of space and food. The aim of this work was to compare and evaluate the growth of Prochilodus lineatus (PL) in monoculture, in contrast to polyculture of PL and pacu ...
