Abstract

BACKGROUND: The cryopreservation of the sperm of the depik fish, Rasbora tawarensis, has previously been developed. However, the quality of the sperm post cryopreservation was not satisfactory and might be improved through the application of antioxidants.

OBJECTIVE: To determine the most suitable antioxidant for the cryopreservation of the depik fish spermatozoa.

MATERIALS AND METHODS: A completely randomized design with a non-factorial experiment was used and the tested antioxidants were glutathione, beta-carotene, ascorbic acid, and butylated hydroxytoluene (BHT) at 6 % concentrations. All treatments had three replications. The sperms were collected from 10 male fishes and diluted with Ringer solution in a ratio of 1: 20 (v/v, sperm: Ringer solution). Then 5% DMSO and 5 % egg yolk were added to the diluted sperms. Furthermore, 6 % of the tested antioxidants were added to the diluents, and then, cryopreservation was carried out in liquid nitrogen for 14 days.

RESULTS: The ANOVA test showed that the application of antioxidants significantly affected the sperm motility, fertility, and hatching rates of the eggs (P < 0.05). Furthermore, the antioxidants also protected the sperm cells during cryopreservation, with glutathione being the best antioxidant.

CONCLUSION: The application of antioxidants during the cryopreservation of depik fish sperm had a significant effect on motility, fertility and hatchability of eggs post-cryo. Furthermore, glutathione was the most suitable antioxidant. doi.org/10.54680/fr23110110312.
