Infections in the stomach and intestine can cause starvation and intestinal poisoning. Die-offs of rainbow smelt as a result of Glugea hertwigi infection have the potential to indirectly cause significant (generally beneficial) cascading food web effects. Great Lakes native Atlantic salmon, lake trout, and other salmonids are known to prey heavily upon rainbow smelt . Rainbow smelt is believed to have aided the growth of landlocked Atlantic salmon in Maine.
