Abstract: The golden mussel (Limnoperna fortunei) is a species of macroinvertebrate. This species has become a nuisance in water transfer systems in southern China. Golden mussels have a high reproduction rate and easily attach themselves to pipelines, resulting in macrofouling, high resistance to water flow, damage to pipe walls and clogged pipelines. Various chemical, physical and ecological measures have been implemented in search of effective and sustainable strategies to control golden mussel invasion into water transfer systems. This paper proposes an ecological measure that combines utilizing golden mussel-preying fishes and golden mussel veligers attachment-attracting layer. This attachment-attracting layer uses a pool with a vertically planted bamboo forest that is positioned at the entrance of the water transfer system. As water carries golden mussels through this pool, a majority of them attach themselves onto the bamboo surface before they can reach the water transfer system. When water filters through the gravel and sand bottom layer, the remaining veligers become trapped. Golden mussel-preying fishes are cultured in the pool in order to prey on adult mussels, thus restraining their population.
