ABSTRACT
Cryopreservation is a method of storing genetic material at low temperatures for long periods of time. One of the benefits of cryopreservation is to overcome the problem of population decline. The kancra fish is one of the species of the Cyprinidae family whose population is declining so that conservation efforts are needed. One of the factors that influence the success of cryopreservation is cryoprotectant. Natural cryoprotectants are used because they have lower toxicity than cryoprotectants from chemicals. Egg yolk is a natural cryoprotectant that can maintain cells during the cryopreservation process. The purpose of this study is to evaluate the effect of egg yolk as natural cryoprotectants on motility, viability, abnormalities, and fertilization of 48-hour spermatozoa after cryopreservation. Concentrations of free-range chicken egg yolk used are: 0%, 5%, 10%, 15%, 20% and 25%. The ratio used for sperm dilution is 1:10. Data analysis using the ANAVA test and then followed by the Tukey test. Based on the results of the one-way ANAVA test, it was found that cryoprotectant of free-range chicken egg yolk combined with 10% methanol had an effect (P <0.05) on motility, viability, abnormality, and fertility of post-cryoprotected spermatozoa. Egg yolk concentration of 5% was the optimum concentration that can maintain the highest percentage of motility, viability and fertility, respectively 84.06 ± 1.67%, 82.13 ± 1.75% and 92.96 ± 1.94% and the percentage value the lowest abnormality was 25.25 ± 2.22%."

ABSTRACT
Cryopreservation is a method of storing genetic material at low temperatures for a certain period of time. Spermatozoa cryopreservation can be used as an ex situ conservation method for kancra fish (Tor soro) whose population is declining. Selection of the right cryoprotectant can minimize damage caused by the formation of ice crystals and maintain the quality of spermatozoa during cryopreservation. Brown sugar as natural cryoprotectant and 10% methanol have potential for cryopreservation of spermatozoa. The research objective was to obtain the optimal concentration of various concentrations of brown sugar and 10% methanol on the motility, viability, and abnormalities of kancra fish spermatozoa after cryopreservation, and evaluate the fertility of kancra fish spermatozoa after cryopreservation. The concentration of brown sugar used were 0%, 5%, 10%, 15%, 20%, and 25%. The ratio between semen and diluent solution used was 1:10. Equilibration was carried out at 5 °C for 10 minutes. Freezing was carried out at -10 °C for 48 hours. Thawing was done at 40 °C for 60 seconds. Data was analyzed using ANOVA test followed by Tukey test. The results showed that the cryoprotectant brown sugar had an significant influence (P<0.05) on the quality of post-cryopreserved spermatozoa. 15% brown sugar together with 10% methanol can produce the highest percentage of motility (81.85 ± 1.11%), viability (83.75 ± 1.71%), fertility (89.75 ± 1.71%), and the lowest abnormality (14.50 ± 1.73%) in spermatozoa post-cryopreservation."
