“…For example, Miskolczi et al obtained haploid malformed African catfish, Clarias gariepinus , larvae from eggs fertilized with frozen–thawed sperm and suggested that cryopreservation damaged the genome. In Russian sturgeon, Acipenser gueldenstaedtii , the number of cells with chromosome aberrations were high for embryos fertilized with frozen–thawed sperm, while in silver catfish, Rhamdia quelen , cryopreservation had no impact on genetic variability of offspring, but the production of normal larvae decreased . On the contrary, neither fresh nor frozen–thawed sperm had an impact on rates of larval malformations for other species, and when abnormalities were observed, they were not enhanced for frozen–thawed sperm …”

Background Gamete cryopreservation causes cellular damage and death. This study develops cryopreservation techniques for Levantine scraper, and deciphers how early offspring development is affected when eggs are sired with fresh and frozen‐thawed sperm. Results Cryopreserved sperm did not affect embryogenesis at two‐ and four‐cell stages, but impaired embryonic development at eight‐cell stage. Embryonic viability decreased at organogenesis, where only 34‐49% of embryos showed viability with frozen‐thawed sperm. Hatching success and percentage of normal hatched embryos declined when fertilized with frozen‐thawed sperm. Considering only frozen‐thawed cells the dimethyl sulfoxide (DMSO)‐5%, methanol (METH)‐5%, and METH‐10% treatments yielded highest hatch, while METH‐5% and propylene glycol‐5% yielded the most normal hatched embryos. Larval spinal torsion was higher for fresh than frozen‐thawed sperm, where larvae with spinal torsion showed vertebral fusion and shape alterations during exogenous feeding. Both fresh and cryopreserved treatments showed abnormalities in caudal skeleton, while rates of defective yolk‐sacs were higher for cryopreserved sperm, where larvae with defective yolks showed oversized yolk extension. Percentage of larvae with defective heads/eyes were also higher for cryopreserved sperm. Conclusions Results show how frozen‐thawed sperm impairs embryonic/larvae development and identifies frequency and position of abnormalities. Future studies should investigate how sperm DNA damage may have caused these alterations.

Prochilodus lineatus is a South American fish of great economic and social importance that is impacted by high fishing pressure. Restocking programmes have tried to be effective in recovering natural populations; however, genetic and reproductive methodologies are necessary to make feasible the survival of released fingerlings. The genetic variability of P. lineatus subjected to semi-natural and artificial reproduction was evaluated. Caudal fin samples from 25 breeders subjected to an artificial reproduction were collected at different sex ratios (1#:1$ and 2#:1$), and 138 fingerlings originated from these spawning. Similarly, samples were collected from 10 breeders (1#:1$) subjected to a semi-natural reproduction, and 70 fingerlings were generated from this spawning. Ten microsatellite loci were evaluated, producing 142 alleles. High interpopulation variability for broodstock and fingerlings was observed in both reproductive systems. A deficit of heterozygotes through the inbreeding coefficient (Fis) was obtained. Moreover, a deviation in the Hardy-Weinberg equilibrium of the fingerlings in both systems was detected. Fst values indicated a moderate genetic differentiation in 1:1 artificial reproduction system and low differentiation in 2:1 artificial and 1:1 seminatural reproduction system. Despite the high genetic variability, genetics analyses in the next generations of fingerlings will be necessary considering the likelihood of a decrease in genetic variability. ARTICLE HISTORY

South American fish species suitable for aquaponics: a review

et al. 2021

Tilapia and catfish are the most popular fish species in aquaponics. However, they are not well-accepted in all markets, and finding alternative species is important in order to increase the variety of food products and meet market demands. South America has several potential fish species for aquaponics systems. Encouraging the implementation of integrated aquaculture systems by providing information about the production of South American species can help to increase the supply of high-quality food and aquaculture diversification. Thus, data for five South American fish species with potential for aquaponics were compared with existing data for the main traditional warm water species in this system, tilapia and catfish. Moreover, the degree of suitability of the novel species for these systems in terms of zootechnical performance, tolerance to water quality and nutritional composition of fish flesh were discussed. The South American species considered were jundia or silver catfish (Rhamdia quelen), yellowtail lambari (Astyanax lacustris), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and snook (Centropomus spp.). Their description and the tabular comparison with the most traditional aquaponic-cultured species show they are suited for this production system. How suitable they are will depend on the system design, as well as the regional characteristics of the market where they will be produced.
