The golden mussel reproduces externally, i.e. males and females release their gametes (sperm and oocytes) into the water, where fertilization takes place and the embryos, larvae and adults subsequently develop. Wild and genetically modified mussels will undergo laboratory reproduction and larviculture to produce up to five generations (in a containment system). The process involves techniques such as sexing, inducing spawning, counting viable gametes, counting and staging larvae, producing microalgae to feed the mussels, among others.
