Artificial reproduction of Capoeta trutta: effects of sGnRHa intramuscular injection and sustained-release implantation on sperm parameters and steroid hormones

Key Points

• SGnRHa treatment significantly improves sperm parameters in Capoeta trutta—enhancing fertility outcomes.
• The sustained-release implantation method leads to higher testosterone levels compared to intramuscular injection.
• Assessment using hormonal analysis reveals distinct changes in steroid hormone levels post-intervention.
• Findings highlight potential new strategies for artificial reproduction in fish breeding and aquaculture.
