An international team of researchers, including CIIMAR, has developed a new tool that could help produce clams that are more resistant to disease and climate change while also strengthening the conservation of these species' genetic diversity. The study, published in the journal Aquaculture, represents a significant step forward for sustainable aquaculture and the management of two of the most economically important clam species: the Japanese clam (Ruditapes philippinarum) and the good clam (Ruditapes decussatus).
