CRINVERT \u2013 Cryopreservation of larvae of commercially important marine invertebrates<\/strong><\/h2>

The CRINVERT project<\/strong> (CIMA 24\/02)<\/strong> arises from a collaboration agreement between the Galician Ministry of the Sea<\/strong> and the University of Vigo, with the goal of developing a research line focused on the cryopreservation of larvae of commercially important marine invertebrates<\/strong>, such as bivalve mollusks and echinoderms. This initiative aims to improve the productivity of Galician hatcheries and contribute to the sustainability of marine resources through the use of advanced biotechnologies. <\/p>

<\/h3>

Context and motivation<\/strong><\/h3>

Galicia is a benchmark in the production and quality of bivalve mollusks, both from fishing and aquaculture. However, the number of hatcheries capable of supplying seed is very limited, which restricts production stability and increases dependence on natural spat collection. In addition, landings of species such as the pullet carpet shell, grooved carpet shell, striped venus clam, and cockle have shown a significant decline over the past decades. <\/p>

In this context, hatchery seed production is an essential tool to support the management of natural banks. The CIMA centers of Cor\u00f3n and Ribadeo are already working on improving seed production and applying new biotechnological techniques, among which cryopreservation stands out\u2014an approach that allows larvae to be preserved at low temperatures for use whenever the sector requires them. <\/p>

This technology offers advantages such as:<\/p>

  • Possibility of carrying out controlled mass spawnings<\/strong> and having larvae available on demand.<\/p><\/li>

  • Reduction of pressure on natural seed<\/strong>, improving environmental sustainability.<\/p><\/li>

  • Adaptation to the biological cycles<\/strong> of species and to the needs of the aquaculture sector.<\/p><\/li><\/ul>

    The collaboration with the University of Vigo is fully justified by the experience and expertise of its research team, led by Dra. Estefan\u00eda Paredes <\/strong>, a pioneer in marine cryobiology with numerous publications in the field of larval cryopreservation.<\/p>

    <\/h3>

    Project objectives<\/strong><\/h3>

    The main goal of the CIMA 24\/02 agreement is to improve the productivity of marine invertebrate hatcheries<\/strong> through the application and optimization of cryopreservation techniques.
    The objectives are divided into two levels:<\/p>

    <\/h4>

    Strategic objectives<\/strong><\/h4>

    • Provide the CIMA centers of Cor\u00f3n and Ribadeo<\/strong> with trained personnel in cryobiology and the necessary infrastructure to develop this technology.<\/p><\/li>

    • Establish a stable collaboration<\/strong> with the University of Vigo to provide scientific and training support to CIMA staff.<\/p><\/li>

    • Improve the technical, economic, and environmental performance<\/strong> of hatcheries, enabling year-round juvenile production.<\/p><\/li>

    • Prevent the loss of valuable strains<\/strong> through the cryogenic storage of samples.<\/p><\/li>

    • Design a complete technological package<\/strong> that can be transferred to private industry and scaled up to an industrial level.<\/p><\/li><\/ul>

      <\/h4>

      Operational objectives<\/strong><\/h4>

      • Train CIMA personnel in cryobiology applied to aquaculture.<\/p><\/li>

      • Take advantage of natural spawning periods to achieve maximum yield in spawnings and larval production.<\/p><\/li>

      • Transfer the protocols developed at the University of Vigo and adapt them to the conditions of Galician centers.<\/p><\/li>

      • Increase the survival rates<\/strong> of cryopreserved larvae.<\/p><\/li>

      • Test new combinations of cryoprotectants, freezing rates, and antioxidants.<\/p><\/li>

      • Determine the optimal larval concentrations<\/strong> during the cryopreservation process.<\/p><\/li>

      • Create a biobank of cryopreserved samples at the CIMA centers of Cor\u00f3n and Ribadeo, ensuring their preservation and traceability.<\/p><\/li><\/ul>

        <\/h3>

        Work plan<\/strong><\/h3>

        The project is being carried out over four years (2024\u20132027)<\/strong>, with progressive activities in training, experimentation, and evaluation:<\/p>
