Retracted: Effect of Post‐Thaw Storage Time on Motility and Fertility of Cryopreserved Beluga Sturgeon (Huso huso) Sperm

Abstract

The aim of this study was to test the influence of post-thaw storage time on the duration of sperm motility, percentage of motile sperm, and fertilization and hatching rates of fresh sperm and sperm stored for 0, 30 and 60 min at 4°C post-thawing. After being frozen in liquid nitrogen and then thawed, the percentage of motile sperm and duration of motility were not affected by 30 min of storage at 4°C, whereas a significant decline in these parameters was observed after 60 min of storage. Similarly, fertilization and hatching rates were significantly affected within 60 min of storage at 4°C, and the fertility of frozen-thawed sperm was significantly lower than that of fresh sperm. We conclude that cryopreserved sperm of beluga sturgeon could be stored for 30 min without the loss of sperm quality. This described procedure for beluga sturgeon cryopreservation is reliable and efficient and therefore can be recommended for hatchery practice after scaling up this technique.

Chilled and post‐thaw storage of sperm in different goldfish types

“…(Aramli & Nazari, 2014;Bernáth et al, 2015;Horváth et al, 2015). The methods described above can support selective breeding and conservation programmes, as well as the hatchery practice in various fish (Aramli, Nazari, & Gharibi, 2015;Cabrita et al, 2010;Glenn et al, 2011).…”

Disaccharide combinations and the expression of enolase3 and plasma membrane Ca2+ATPase isoform in sturgeon sperm cryopreservation

“…There are many published articles describe sperm cryopreservation in sturgeon as a biological tool to preserve germ cells and maintain gene banking due to lack of sturgeon brood‐fish (Alavi et al., ; Billard et al., ). Sperm cryopreservation techniques are well developed for many fish species, including sturgeon, and are crucial for resource conservation and aquaculture practices (Aramli, Nazari, & Gharibi, ; Aramlia & Nazarib, ; Glogowski et al., ; Huang et al., ; Lahnsteiner, Berger, Horvath, & Urbanyi, ). However, few studies are known to research the cryopreservation of A. sinensis and A. dabryanus sperm.…”

Comamonas piscis sp. nov., isolated from the intestine of a Korean rockfish, Sebastes schlegelii

“…The Korean rockfish, Sebastes schlegelii, is a predatory species of small fishes in northern Asia (Aramli et al, 2015), and the fish are an important resource for both the wild fishery and aquaculture in Korea, Japan and China. The annual aquaculture production of Korean rockfish reached 17 338 t (MFAFF, 2013).…”
