Synopsis (short abstract) Genetic diversity is fundamental to a species’ ability to adapt, evolve, andsurvive over time, while also providing essential services to humankind.In the context of food and agriculture, this diversity results from bothnatural evolution and artificial selection through domestication and geneticimprovement. Maintaining and restoring such diversity is critical to ensure thelong-term sustainability and adaptive potential of both wild and domesticatedspecies. Gene banking is one tool that is valuable in the conservation andmanagement of these genetic resources. This document provides technicalguidelines for the ex situ in vitro conservation of aquatic genetic resourcesfor food and agriculture, including finfish, shellfish, seaweed, and microalgae.As one of the strategic priorities of the FAO Global Plan of Action forthe Conservation, Sustainable Use and Development of Aquatic GeneticResources, ex situ in vitro conservation plays a role complementary to in situefforts of protected areas and live gene banks, contributing to the sustainablemanagement of aquatic biodiversity. However, compared to the crop andlivestock sectors, in vitro conservation of aquatic species is stillunderdeveloped, facing challenges such as the extremely broad diversityof species and physiology, lack of standardized protocols, inconsistentterminology, and limited reporting guidelines.The present volume aims to support policymakers, resource managers,conservationists, aquaculture producers, and researchers in advancing thedevelopment and application of in vitro conservation for gene banking andselective breeding.The guidelines provide an overview of current practices, with practicalinformation on existing methods (particularly cryopreservation), theestablishment and organization of gene banks, regulatory considerations,and cost implications. Technical elements, including examples of laboratoryprotocols, are included to support practitioners and to facilitate thedevelopment of new methods. Experiences from different parts of the worldshow how challenges are faced under different circumstances, and how theapproach provides tangible benefits.Progress in the ex-situ in vitro conservation of aquatic species and a broaderapplication of in vitro conservation technologies would significantly improvethe management of both wild and domesticated aquatic genetic resources.

    This report provides an overview of developments in the implementation and operations of the Multilateral System of Access and Benefit-sharing over the past 18 years (1 January 2007 –1 January 2025). In response to a request from the Governing Body, it offers a structured and integrated analysis of data, examining the Multilateral System from multiple perspectives to better understand its practical functioning. In addition to detailed information on available materials and germplasm transfers, the report includes illustrative narratives that highlight the system’s real-world relevance and impact. A key objective of this report is to enhance visibility for the many contributors who sustain the Multilateral System. It acknowledges the essential roles played by gene banks, farmers, CPs and other institutions in maintaining the flow of germplasm across borders. Adopting a multistakeholder lens, the report brings together diverse viewpoints from across the plant genetic resources community. Through selected case studies and testimonials, it illustrates how the system operates in practice by drawing on the experiences of: • gene bank staff managing and distributing vital genetic resources; • farmers who have contributed to and benefited from improved crop varieties; • national focal points coordinating implementation efforts; • policymakers contributing to decision-making efforts; • plant breeders developing new varieties for sustainable food production; and • researchers studying, evaluating and documenting materials to enhance their value. This document also combines data and statistics that have been included in the Report on the Implementation and Operations of the Multilateral System (IT/GB-11/29.1) presented to the Governing Body, as well as additional information and insights targeting the above-mentioned stakeholders. The information is intended to sustain a broader dialogue that has unfolded over many years, reflecting the collective commitment to improving the Multilateral System’s functionality and long-term viability. The report serves both as an informational resource and an advocacy tool. It highlights stories of women and men, and pairs practical applications with rigorous data analysis to make the concepts of plant genetic resource exchange through the Multilateral System more tangible and relatable.
