“…The sturgeon egg must have a saturation point in its ability to digest such a large number of spermatozoa permitting embryonic development. Ciereszko et al (62) suggested that cryopreserved spermatozoa will become a standard practice in future reproduction in sturgeon fisheries. Indeed, fertility preservation strategies using cryopreservation have enormous potential for helping sustain and protect rare and endangered species.…”

Intracytoplasmic sperm injection in sturgeon species: A promising reproductive technology of selected genitors

Sturgeons are the most endangered species group and their wild populations continue to decrease. In this study, we apply intracytoplasmic sperm injection (ICSI), an assisted reproductive technology, for the first time in endangered and critically endangered sturgeons. Using various egg-sperm species combinations we performed different ICSI experiments with immobilized pre- or non-activated spermatozoa, single or many, fresh or cryopreserved. Then we evaluated the fertilization success as well as the paternity of the resultant embryos and larvae. Surprisingly, all experimental groups exhibited embryonic development. Normal-shaped feeding larvae produced in all egg-sperm species-combination groups after ICSI using single fresh-stripped non-activated spermatozoa, in one group after ICSI using single fresh-stripped pre-activated spermatozoa, and in one group after ICSI using multiple fresh-stripped spermatozoa. ICSI with single cryopreserved non-activated spermatozoa produced neurula stage embryos. Molecular analysis showed genome integration of both egg- and sperm-donor species in most of the ICSI transplants. Overall, ICSI technology could be used as an assisted reproduction technique for producing sturgeons to rescue valuable paternal genomes.

“…According to [21], active spermatozoa will velocity (motile) toward microfil (micro-sized the openings in the egg). [5] revealed that sperm motility considerably impacts the success of sperm-egg fertilization. Even though there are inherent variances in penaeid shrimp populations based on geographical location, as reported by [1] and [2].…”

High-quality broodstock is required to support successful cultivation activities of the tropical abalone. This study aimed to find out the structure of the sperm under the influence of individual selection. A total of 50 eggs per batch were measured in egg diameter, calculated by the degree of fertilization and hatching rate. Sperm collection is carried out from the natural spawning of male abalone from the wild (F0) and the selected offspring from individual Fillial-1, F2, and F3 selections. Samples of sperm were collected by artificial spawning and analyzed using the Sperm Class Analyzer® CASA System. The results showed that the wild abalone (F0) had the highest hatching rate but was not significantly different from other derivatives (P > 0.05). The average spermatozoa was 2.39 million cells/m, with the highest spermatozoa (F0) of 7.110 million cells/ml. The most increased sperm motility and rapid velocity were in the wild (89.78%; 34.00%) and the lowest of F2 (22.00; 4.00%). A significant difference in sperm motility and rapid velocity were found between F0 and other treatment. The consequences of individual selection will aid in studying reproductive factors and sperm motility, which are most likely crucial in tropical abalone fertilization.

There is growing concern over the effects of increased salinization on freshwater organisms, which are largely unknown for unionid mussels. Adult and larval Elliptio complanata were exposed to low-level salt concentrations to determine the effects on mussel survival, physiology, and reproduction. Adults were exposed to salt concentrations of 0 parts per thousand (ppt), 2 ppt, 4 ppt, and 6 ppt NaCl and monitored over 7 d for mortality. Treatment groups exposed to 6 ppt and 4 ppt experienced 50% mortality at day 3 and day 4, respectively, with complete mortality by day 7. No mortality was observed in the other treatments. Adults were also exposed to sublethal salinity levels of 1 ppt and 2 ppt NaCl for 4 wk to determine physiological consequences of prolonged salinity exposure. Mussels exposed to 1 ppt and 2 ppt experienced reduced metabolic rates within the first 24 h of exposure that recovered to control levels in the 1-ppt treatment within 7 d. Metabolic recovery did not occur in the 2-ppt treatment by the end of 28 d. Glochidia exposed to 3-ppt NaCl during attachment to their host fish suffered a reduction in attachment success and metamorphosis, resulting in a 10-fold reduction in the number of juveniles produced per host fish. The present study demonstrates that low levels of salt can have a dramatic effect on the reproduction, physiology, and survival of freshwater mussels.
