Immunohistochemical Study of Pituitary Cells in Wild and Captive Salminus Hilarii (Characiformes: Characidae) Females During the Annual Reproductive Cycle [PDF]
SpringerPlus, 2013 Abstract Freshwater fish that live exclusively in rivers are at particular risk from fragmentation of the aquatic system, mainly the species that migrate upriver for reproduction. That is the case of Salminus hilarii, an important migratory species currently classified as “almost threatened” in the São Paulo State (Brazil), facing water ...

Influence of Spawning Procedure on Gametes Fertilization Success in Salminus Hilarii Valenciennes, 1850 (Teleostei: Characidae): Implications for the Conservation of This Species [PDF]
Neotropical Ichthyology, 2011 Artificial reproduction and gamete fertilization were evaluated in Salminus hilarii wild and domesticated broodstocks. Wild and domesticated broodstocks were artificially induced to reproduction using a carp pituitary treatment.

Ichthyofauna used in traditional medicine in Brazil. [PDF]
Evid Based Complement Alternat Med, 2012 Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary

Environmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023 We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.
