Core Viewpoint - The successful import of African killifish eggs marks a significant advancement in China's research capabilities, particularly in organ regeneration and aging studies, while also highlighting the importance of risk management in biological imports [1][2]. Group 1: Import and Research Significance - The first batch of 200 African killifish eggs has been imported under strict customs supervision, representing China's first introduction of this model organism [1]. - African killifish is the shortest-lived vertebrate suitable for laboratory breeding, with a lifespan of 4-6 months, and offers unique advantages in research due to its rapid growth and ability to enter embryonic dormancy [1][2]. - The introduction of this species is expected to enhance research on spinal cord regeneration and the molecular mechanisms behind aging-related declines in regenerative capacity [2]. Group 2: Risk Management and Regulatory Measures - Beijing Customs has implemented a "dynamic risk assessment" mechanism to evaluate potential risks associated with the import of African killifish, focusing on disease outbreaks and invasive species [2]. - Strict quarantine measures are in place to prevent the spread of animal diseases and mitigate the risks of species invasion following the import of the fish eggs [2]. - The successful import serves as a replicable model for future imports of research organisms, filling a gap in China's vertebrate model organism resources [2].
