N2  - The Mariculture of Tridacna is greatly affected by pathogenic bacteria including those of vibrio species that result in high losses 
The present work was designed to investigate the most common bacterial infections of indoor aquarium and offshore cages culture 
Tridacna maxima and Tridacna gigas in Hurghada, red sea governorate, Egypt. Eighty Specimens of booth Tridacna maxima and Tridacna 
gigas in indoor aquarium and in offshore cages were subjected to clinical and bacteriological examination. The bacteria were 
recovered from gills, gut mantel and gonads of collected Tridacna samples. Decrease in movement and loss of attractive color 
pattern with 25 % and 20 % mortality rate were detected in indoor cultured Tridacna maxima and Tridacna nagigas respectively, 
while no changes in clinical picture or postmortem findings were detected in offshore cages culture Tridacna. 46 bacterial isolates 
were obtained and were identified by phenotypicall characterization and biochemical tests as Vibrio logei, V harveyi and unidentified 
Vibrio species. Experimental infection with V. logei proven its pathogenicity to Tridacna with 30% mortality rate
