in larval growth rate without immediate extensive mortality. It was not 

 possible to tell if bacteria destroy larvae in nature, where both usually 

 are less concentrated than in cultures. Use of antibiotics to control 

 bacteria in larval cultures is apparently more effective when water supply 

 is changed regularly and 2 or more antibiotics are used alternately. The 

 same antibiotics will not prevent growth of injurious bacteria in algal 

 cultures used as food. If impure algal cultures must be used to raise 

 larvae, the algae should be kept at the lowest temp allowing reasonable 

 growth. One of the virulent clones isolated was a species of Vibrio, the 

 other was Pseudomonas . Mortality caused by these bacteria at 20, 25 and 

 30°C did not vary significantly, but both virulent clones grow well at 30°C 

 and higher, which is relatively uncommon for marine bacteria from the Milford 

 area. Thus, high temps in laboratory larval cultures favor these strains.

Hard clam belongs to the genus Meroenaria. On the Fla. west coast production 

 has varied from 102,720 kg of meats in 1962 to 1,580 kg in 1966. Figures may 

 not be accurate because Rangia cuneata is confused by some with cherrystone 

 hard clam. The author listed Meroenaria meroenaria as a potential source of 

 food in the Gulf of Mexico, but did not mention M. campeahiensis . - J.L.M.
