 DN Aquanet is a project aiming to develop genomic tools and indices for use in monitoring and assessing aquatic biodiversity in Europe. These tools will be used to supplement existing methods such as morphological analysis which have limitations in terms of accuracy, cost, and time. The project will also create a network of experts from various fields to train the next generation of researchers in the use of these tools. Finally, the project will work closely with policy makers, regulators, and other stakeholders to ensure that the tools are implemented into legal frameworks.
