Survey of Oyster Populations in Aransas and Copano Bays-Survey of the Oyster Fishery in Area MO-2


Population studies of five reefs in Aransas and Copano Bays have shown that the oyster growth was retarded during the months of November, 1960 through March, 1961, by an overabundance of fresh water from abnormally heavy rainfall in the central coastal region. Copano Bay had heavy mortality from the fresh water on the reefs near Mission Bay and the Aransas River. Spat set in June and July, 1961, was heavy, creating an overabundance of small oysters on the reefs in the two bays.
