SHORT-TERM VARIATION OF BACTERIAL COMMUNITIES CONCENTRATION AND ACTIVITY IN AQUACULTURE ECOSYSTEMS. Two kinds of short-term experiments were carried out on sea-water bacterial commun­ities of shrimp aquaculture in Polynesia at the Centre Océanologique du Pacifique (Tahiti). A 12 m3 sea-water tank was considered. The total number (AOC) and hétérotrophie activity of bacteria were studied during a 48 hours experiment with a 2 hours sampling time The total bacterial community was about 10? bacteria, and nitrifying bacteria were about 10 bacteria ml-1 and could showed doubling time of 7 hours. Several nitrogen sources were added in five liter flasks. With N-NH4 enrichment no great changes in activity and number could be seen. With organic nitrogen the number of...
