Following the reappearance of "black mud" in May 1953, a meeting was held at Tappahannock to diacuss possible causes of the condition and the steps which might be taken if there was a recurrence of mortality such as followed the "black mud" in 1949. Lacking any clear cut evidence that pollution or physical factors caused the mortality, we suggested that a newly discovered fungus disease called Dermocystidium marinum be studied as a possible causal factor.
A study has been made of this disease in the Rappahannock River in the past year.
