Overview

Review highlights cryopreservation methodologies and governance for aquatic genetic resources, suggesting improvements for biodiversity preservation.

Key Points

  • This review aims to synthesize methodologies and governance frameworks for the ex situ conservation of aquatic genetic resources, focusing on cryopreservation techniques and challenges.
  • Evaluated cryopreservation workflows including collection, extender dilution, and controlled cooling rates.
  • Analyzed challenges in aquaculture related to taxonomic diversity and reproductive biology across various aquatic species.
  • Investigated governance under the Nagoya Protocol and data management principles for aquatic genetic resources.
  • The review identifies challenges in capturing complete genomes of aquatic species due to oocyte vulnerabilities.
  • Advancements in isolating and cryopreserving primordial germ cells could enhance conservation efforts.
  • Integration of open-source technologies and AI-driven processes is essential for future biorepository networks.
