“…Later studies in other Prochilodus genus report it as a normal component to the cryopreservation media (Atencio et al, 2013;Martínez et al, 2012). Nevertheless, the incorporation of egg yolk in the cryopreservation of coporo spermatozoa presented no significant protective effect compared with media in which it was not included, indicating that the milt of this species can be cryopreserved satisfactorily in a simple media composed of permeating CPA and glucose-similar to that described for curimba , several species of salmonids (Nynca et al, 2016) and that found recently in our laboratory for striped catfish (Pseudoplatystoma orinocoense) (Medina-Robles et al, 2021). These results represent an advantage because factors such as health risks (Yildiz et al, 2013), the presence of highdensity lipoproteins (HDL) and their interference with protein analysis (Pini et al, 2018) and lipid peroxidation analysis using the BODIPY 581/591 C 11 probe (Neagu et al, 2011) have led researchers to consider excluding or replacing it, as well as other biological materials in cryopreservation media (Blommaert et al, 2016;Kumar et al, 2015;Yildiz et al, 2013).…”
