Abstract

The aim of this study was to evaluate cryoprotectants for cooling embryos of B. orbignyanus. 1400 embryos were selected, in the post-gastrulation and subjected to cooling to -8°C with different combinations of intracellular cryoprotectants (methanol and 9% DMSO or associated 4.5%) combined with extracellular cryoprotectants (sucrose and glucose, 17%) diluted in distilled water to complete 100%. For each treatment, 200 embryos were placed in glass tubes and submitted to the cooling process. After the proposed time, the embryos were removed and transferred to four-liter incubation to hatching of the larvae. The results obtained from solutions containing glucose were inefficient. The treatments with association of DMSO showed no satisfactory results. For cooling of B. orbignyanus embryos at -8°C it is suggested to use a cryoprotectant solution containing 17% sucrose associated with 9% methanol.
