*** Water Biology and Security?Water is an essential natural resource for human survival and development,by providing ecosystem services(drinking water,aquatic foods,transportation,hydropower,biodiversity support).Globally,aquatic foods provide more than 20%of the animal protein for the world's human population,with this percentage reaching 50%in some developing countries(FAO,2020).Aquaculture has been transformed from a farming practice into a modern industry with important contributions to global food security(Gui et al.,2018;Naylor et al.,2021;Golden et al.,2021).
