Abstract
Spermatological research of the Patagonian blennie was carried, specifically biometric parameters, sperm density, sperm count and motility in different activation mediums (815, 716, 590 and 0 mOSm kg?1), at different temperatures (5, 10 and 15°C) and pH levels (5, 7 and 9). The results indicate that Patagonian blennie spermatozoa have a primitive form, with a total length of 44.09 ± 3.36 ?m, with a head length of 2.15 ± 0.28 ?m and head width of 2.5 ± 0.31 ?m. The mid-piece had a length of 0.72 ± 0.12 ?m, and its tail measures 41.21 ± 3.21 ?m long. The motility pattern indicates that the spermatozoa are found immobile in the seminal plasma and only initiates its movement in a hypertonic medium from 590 to 815 mOsm kg?1. The longest motility time that was registered at 10°C in 716 mOSm kg?1 was of 245 ± 39 s and an optimum pH of 7 was observed. © 2017 Elsevier B.V., All rights reserved.
