This can help garner support for conservation initiatives and promote the responsible use of algal resources (Yong et al., 2020; Priyanka et al., 2021). Robust policy and regulatory frameworks are crucial for the effective conservation and sustainable utilization of algal germplasm. By integrating conservation strategies, promoting research, strengthening legal frameworks, engaging stakeholders, and fostering international collaboration, we can ensure the long-term preservation and responsible use of these valuable genetic resources. 8 Challenges and Opportunities 8.1 Conservation challenges The conservation of algal germplasm faces several significant challenges. One major issue is the difficulty in maintaining and preserving the genetic diversity of algae in both in situ and ex situ conditions. In situ conservation efforts are often hampered by environmental changes, pollution, and habitat destruction, which can lead to the loss of natural populations. Additionally, the establishment and maintenance of marine protected areas (MPAs) are often met with logistical and financial constraints, making it challenging to effectively protect algal diversity in their natural habitats (Wade et al., 2020). Ex situ conservation methods, such as germplasm banking and cryopreservation, also face technical difficulties. Developing effective cryopreservation protocols for various algal species is complex due to the unique physiological and biochemical characteristics of algae. Moreover, the lack of standardized methods for cryopreservation and the limited availability of cryopreserved algal strains in germplasm banks pose additional hurdles (Yang et al., 2021). Furthermore, there is a need for coordinated international efforts to integrate and manage algal germplasm repositories effectively. 8.2 Utilization challenges The utilization of algal germplasm for biotechnological and industrial applications also presents several challenges. One of the primary obstacles is the high operational and capital costs associated with large-scale algal cultivation and biomass processing. The economic feasibility of producing algal biofuels and other bioproducts remains a significant challenge, primarily due to the costs related to harvesting, dewatering, and downstream processing (Rao et al., 2021). Another challenge is the technical complexity of integrating algal cultivation systems with industrial processes, such as wastewater treatment and carbon capture. Achieving optimal growth conditions and maintaining stable algal cultures in open ponds or photobioreactors are difficult due to the variability in environmental conditions and the risk of contamination by other microorganisms (Pathak et al., 2018). Additionally, the regulatory frameworks for the use of genetically modified algae and the potential environmental impacts of large-scale algal operations need to be carefully considered and managed (Shokravi et al., 2021). 8.3 Opportunities for collaboration and innovation Despite these challenges, there are significant opportunities for collaboration and innovation in the conservation and utilization of algal germplasm. Collaborative efforts between academic institutions, industry, and government agencies can drive research and development in algal biotechnology. For instance, integrating algal cultivation
