Abstract
We investigated methods for cryopreserving sperm from the endangered gudgeon, Microphysogobio rapidus, by examining the effects of cryoprotective agent (CPA) concentration, diluent, and dilution ratio on post-thaw sperm quality. The quality of frozen sperm was evaluated in terms of motility and kinematic parameters, viability, DNA damage, and fertilization rate. We evaluated methanol, glycerol, dimethyl sulfoxide (DMSO), and ethylene glycol as CPAs. Sperm motility, velocity, and viability were significantly higher when methanol was used as the CPA (p < 0.05). The diluents tested were Ringer's solution, Kurokura's Extender, Common Carp Sperm Extender (CCSE), and buffered sperm motility-inhibiting saline solution (BSMIS); post-thaw motility was highest when Ringer's solution was used as the diluent. Next, various quantities of methanol were combined with Ringer's solution to identify the optimal dose of methanol. The dilution ratios tested ranged from 1:1 to 1:7. Cryopreserved sperm was thawed at 20 °C for 15 s. The use of 10% methanol with Ringer's solution at a dilution ratio of 1:5 resulted in the highest post-thaw sperm motility, viability, and velocity including VAP, VCL, and VSL. Post-thaw sperm showed significantly greater DNA damage than the control (fresh sperm) (p < 0.05). The fertilization rate was highest with fresh sperm (p < 0.05), followed by sperm frozen with 10% methanol + Ringer's solution. We recommend that the best way to preserve sperm in the studied species is to use a combination of Ringer's solution and 10% methanol at a 1:5 dilution ratio. Our findings will facilitate the artificial fertilization of M. rapidus.

Artificial reproduction of the indoor-cultured brackish form of maraena whitefish (Coregonus maraena) under recirculated aquaculture system (RAS) conditions. Anim Reprod Sci 2023; 257:107329. [PMID: 37716089 DOI: 10.1016/j.anireprosci.2023.107329] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 09/04/2023] [Indexed: 09/18/2023]
Abstract
Maraena whitefish (Coregonus maraena) is a promising coldwater aquaculture species, especially in terms of meat quality. This versatile whitefish species, which inhabits both fresh and brackish waters, including the Baltic Sea, offers promising prospects for aquaculture breeding and cultivation. However, the main problem is the lack of availability of spawners of this species. Therefore, in this study, an attempt was made to raise the spawning stock under controlled conditions and then artificially reproduce the fish to obtain high-quality gametes and then larvae. The conducted research showed that successful culture of maraena whitefish spawners is possible under recirculating aquaculture system (RAS) conditions. The application of proper nutrition and manipulation of environmental conditions allowed the breeding of sexually mature whitefish spawners in less than two years in captivity (meat weight 476 g). Through stimulation of environmental conditions (temperature and photoperiod), it was possible to stimulate the final maturation of gametes of the F1 generation of cultured fish. The use of Ovaprim hormonal stimulation induced 100% of females to ovulate within 10 days of injection, compared to 60% of females in the control group. Additionally, the other examined parameters, such as the pseudogonado-somatic index (PGSI: 11.46% vs. 6.80%), fertilization rate (94.2% vs. 60.1%), embryo survival rate (92.6% vs. 41.1%) and embryo survival rate to the eyed-egg-stage (90.0% vs. 28.0), were significantly higher in the hormonally induced group, finally two times and three times, respectively. The mortality rate of spawners, after spawning and within three months of artificial spawning, was extremely low. The results obtained from the study demonstrate the feasibility of culturing the spawning stock of maraena whitefish in captivity and successfully inducing artificial spawning.
