Captivating Colors, Crucial Roles: Astaxanthin's Antioxidant Impact on Fish Oxidative Stress and Reproductive...

Area of Science:

• Aquatic biology
• Fish physiology
• Reproductive science

Background:

• Fish face environmental stressors and high metabolic rates, leading to susceptibility to oxidative stress.
• Oxidative stress negatively impacts fish reproductive parameters, including gamete quality and hormone levels.

Purpose of the Study:

• To review the role of astaxanthin in mitigating oxidative stress in fish reproduction.
• To highlight astaxanthin's benefits for gamete quality, ovary development, and hormone regulation.
• To explore astaxanthin's applications in aquaculture for fish health and pigmentation.

Main Methods:

• Comprehensive literature review of studies on astaxanthin's antioxidant properties.
• Analysis of research on astaxanthin's impact on fish reproductive stages.
• Evaluation of astaxanthin's effects on aquaculture practices.

Main Results:

• Astaxanthin effectively neutralizes reactive oxygen species, inhibiting lipid peroxidation.
• Supplementation with astaxanthin improves fish reproductive success and gamete quality.
• Astaxanthin enhances ovary development, hormone levels, and overall fish health in aquaculture.

Conclusions:

• Astaxanthin demonstrates significant benefits for fish health and reproduction through its antioxidant capabilities.
• Astaxanthin offers economic advantages in aquaculture by improving fish health and pigmentation.
• Further research is needed on species-specific responses and optimal dosages for sustainable aquaculture.
