  Rainbow trout aquaculture is challenging due to the restricted spawning seasons. Sperm cryopreservation technology can help ensure a successful spawning season, but its effectiveness is restricted by oxidative stress during freezing and thawing, which reduces the availability of male gametes. This study aimed to evaluate the effect of several types and concentrations of antioxidants on post-cryopreservation rainbow trout sperm quality. Subsequently, a factorial completely randomized design with three replications was applied, testing four types of antioxidants Ascorbic acid, Myo-inositol, Butylated hydroxytoluene (BHT), and Alpha-tocopherol at concentrations of 0, 20, 40, and 60 mM, respectively. The evaluation parameters included motility rate, sperm lifespan, and sperm motion characteristics using the Computer Assisted Sperm Analysis system. The results showed that the type and concentration of antioxidants significantly affected sperm motility and sperm lifespan (P<0.05). The treatment method carried out using 40 mM Ascorbic acid and 20 mM BHT led to the highest sperm motility of 46.67% and sperm lifespan of 34 seconds. Although both antioxidants showed similar effectiveness, BHT at a concentration of 20 mM is more recommended due to its lower toxicity and technical as well as economic efficiency considerations.

  EFFECT OF ANTIOXIDANT AND ITS CONCENTRATION ON THE SPERM QUALITY OF WALKING CATFISH Clarias batrachus POST CRYOPRESERVATION

  The walking catfish Clarias batrachus is popular and affordable in Southeast Asian countries. The development of breeding technology for this species is ongoing, with sperm cryopreservation being a key aspect of study that supports its breeding program. Cryopreservation is an essential method in fish breeding, particularly for sustaining breeding initiatives that supply larvae throughout the years. However, this process can lead to oxidative stress, which may decrease sperm quality due to structural and physiological damage, including DNA fragmentation. Adding an antioxidant to the freezing medium could help mitigate these negative effects and maintain sperm quality. This study aims to evaluate the effectiveness of various types and concentrations of antioxidant on the quality of C. batrachus sperm post-cryopreservation. Four types of antioxidants were tested: ascorbic acid, Myoinositol, alpha-tocopherol, and Butylated Hydroxytoluene, each at concentrations of 0, 20, 40, and 60 mg/L. Ringer solution, 5% DMSO and 5% egg yolk were used as extender and cryoprotectants, respectively. Sperm samples were stored in liquid nitrogen for 2 weeks, after which sperm quality was analyzed. The results showed that both the type and concentration of antioxidant had a significant effect (p<0.05) on all measured sperm quality parameters. Ascorbic acid at a concentration of 40 mg/L produced the best results, achieving 62.33% motility, 66.00% viability, and 61.67% fertility. Electrophoresis analysis showed no DNA fragmentation in any of the treatments, indicating that the genetic structure of sperm remained intact. Ascorbic acid at 40 mg/L is the most effective antioxidant for cryopreservation of sperm C. batrachus.

  Ascorbic acid ameliorated the sperm quality of rainbow trout (Oncorhynchus mykiss) against arsenic toxicity: Impact on oxidative stress, fertility ability and embryo development

  Kocabaş, Filiz Kutluyer; Kocabaş, Mehmet; Aksu, Önder; Çakir Sahilli, Yeliz

  Arsenic (As) is a heavy metal and aquatic pollutant and adversely impacts the reproduction of male fish. As a chain-breaking antioxidant, ascorbic acid (AA) has high water solubility and low toxicity. In this context, the current study was performed to assess the protective role of AA (1 mM) on the sperm cells of the rainbow trout (Oncorhynchus mykiss) exposed to sublethal concentrations of As (8, 16 and 32 mg/L). Sperm quality parameters were analyzed using a sperm class analyzer system. Lipid peroxidation and antioxidant enzyme levels were used as indicators of oxidative stress. The fertilization, eyeing and hatching rates were determined as gamete markers. Reduced sperm quality parameters and fertility capacity resulted from in vitro exposure to As (P < 0.05). The oxidative stress in sperm cells increased after As exposure (P < 0.05). The presence of AA improved sperm movement parameters and fertility potential (P < 0.05). Overall, AA had a positive effect on oxidative stress and fertility ability against As toxicity and AA supplementation ameliorated detrimental effects of As in sperm cells.
