Grouper aquaculture is rapidly expanding in both tropical and subtropical regions. The presence of marine leeches (; previously named ) infesting cultured groupers, however, can have a fatal effect on grouper aquaculture production and cause significant economic loss. Understanding the marine leech's population structure is therefore important to determine its possible distributional origin and distributional mechanisms, which will help monitor and mitigate the infestation.

A major production constraint in culturing grouper is that the fish can be fatally affected by leeches and diseases. Leeches are an ectoparasite of grouper, which can cause significant loss in fish number, and thus controlling their prevalence is indispensable as a tool of aquaculture management.
