| description |
Experiment was conducted to determine the possibility of using
locally isolated purple non-sulfur bacterium Afifella marina strain
ME to improve the dissolved inorganic nutrients (DIN) in Tilapia
Oreochromis niloticus culture tank. The experiment was conducted
for seven days without changing water. Ammonia (mg/L), nitrite
(mg/L), nitrate (mg/L) and phosphate-phosphorus (mg/L) in the
Tilapia culture tank were monitored. Sixteen tails of Oreochromis
niloticus juveniles with mean weight of 0.7±0.05g were stocked in
ten liter aquarium. Juveniles were fed with commercial feed twice
daily by ad-libitum feeding method. Purple non-sulfur bacterium
Afifella marina strain ME, and established probiotic commercial
Bacillus with four inclusion levels, 0.005(g/L), 0.01(g/L), 0.02(g/L),
and 0.03(g/L) were added everyday into culture tank. At the end of
experiment no significant difference (P > 0.05) were observed among
all the inclusion levels with the concentration of ammonia, nitrite,
nitrate and phosphate. The lowest concentration of ammonia, nitrite,
nitrate and phosphate were observed in both Afifella marina strain
ME, and commercial Bacillus with the inclusion level of 0.03g/L.
Obtained results were comparable with commercially established
probiotics Bacillus sp. Locally isolated purple non-sulfur bacterium
Afifella marina strain ME could be one of the potential candidate in
controlling dissolved inorganic nutrients in aquaculture system. |
