The aerobic bacterial flora in the gut of turbot larvae and their influence on larval survival was examined. Two turbot experiments were run with six replicates each time. Large variation, from 0% up to 44%, was observed in the survival percentage of turbot larvae. There was no correlation between the number of bacteria present in the gut of turbot larvae and the larval survival rate. During both experiments, all replicates followed nearly the same rate of bacterial development in the gut of turbot larvae going from circa 10<sup>2</sup> CFU larva<sup>-1</sup> just before first feeding at day 3 post hatch to 10<sup>5</sup> CFU larva<sup>-1</sup> at day 9 post hatch.In total, 127 bacterial isolates from 12... |

Several bacteriological surveys were performed from 1994 to 1996 at different <i>Litopenaeus vannamei</i> hatcheries (in Ecuador) and shrimp farms (in Mexico). Samples were taken from routine productions of healthy and diseased <i>L. vannamei</i> larvae, postlarvae, and their culture environment and from healthy and diseased juveniles and broodstock. In Ecuador, the dominant bacterial flora associated with shrimp larvae showing symptoms of zoea 2 syndrome, mysis mold syndrome, and bolitas syndrome has been determined. Strains were characterized by Biolog metabolic fingerprinting and identified by comparison to a database of 850 <i>Vibrio</i> type and reference strains. A selection of strains was further genotypically... |

This paper explores the role of selective attraction to food in determining the spatial (micro)distribution of closely related nematode species. The attractiveness of 3 different bacterial strains to 4 species of Monhysteridae, <i>Diplolaimelloides meyli, Diplolaimella dievengatensis, Monhystera</i> sp. and <i>Geomonhystera disjuncta</i>, was studied in a multiple choice design. In our study area, the 4 nematode species considered are associated with <i>Spartina anglica</i> detritus decay and have partially overlapping microhabitat preferences. As they all belong to the same feeding guild, they are potential competitors for food. Each of the 4 nematode species was attracted to the bacterial strain B1, but important... |

Samplings were organized in three marine fish hatcheries. Samples were taken at different steps during the production of algae, rotifers and <i>Artemia</i> . There were 233 dominant colony types isolated for further characterization. The isolates were compared to each other and to reference strains of <i>Photobacterium, Vibrio</i> and <i>Alteromonas</i>, using cellular fatty acid fingerprints. Fatty acid profiles of the isolates were grouped using principal component analysis. The isolates fell into at least ten major groups, of which two correspond to the genera <i>Vibrio</i> and to <i>Alteromonas</i>, respectively. Some groups seem to be restricted to a particular type of live food or isolation... |
