Full description
This study examined microbial infestation of phyllosomas, including proliferation of bacteria in the hepatopancreas and heavy external fouling of appendages and cuticle with filamentous bacteria and sessile protozoa.Culture- and molecular-based microbial community analysis was performed on the water column, tank biofilm and whole phyllosomas of standard larval-rearing environments.Scanning electron microscopy confirmed fouling by filamentous bacteria of at least two morphological types and also fouling by rod-shaped bacteria.Phyllosoma survival as a percentage of the whole population (measured over 3 separate standard larval-rearing trials) were calculated from daily counts of dead animals siphoned from the bottom of each larval-rearing tank. No correlation between bacterial numbers (measured as colony-forming units mL-1) and phyllosoma mortalities was established.To investigate the microbiological and histopathological factors affecting early stage phyllosomas.
