Sperm Quality, Milt Biochemistry, and Cellular Ultrastructure in Fresh and Cryopreserved Sperm of Brycon amazonicus

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.
