Deteksi keberadaan bakteri Aeromonas sp pada ikan nila yang dibudidayakan di karamba jaring apung danau Tondano
ABSTRACT: The purpose of this
study was to detect the presence of bacteria Aeromonas sp in tilapia
(Oreochromis niloticus). Nine fish with an average body weight of 150-200 g
were used in this study as samples. Sampling was conducted at three different
locations which were representative of fish culture sites located on Lake
Tondano. The number of sample gathered from each location was and 3 fish which
were taken randomly. Fish samples were taken by using a scoop, then the samples
were taken alive by placing in an oxygen-filled plastic separately and taken
direcly to lab Fish Disease Control and Environmental Center, Tateli,
Department of Marine and Fisheries of North Sulawesi province, for examination
the presence of bacteria. Isolation of bacteria were conducted by taking
samples from gill and kidney. This study was carried out from April - July
2013. Identification of the presence of bacteria was done through a series of
observations of colony morphology and gram staining of bacteria, followed by a
series of biochemical tests: oxidase test , catalase test , test TSIA , H2S
production test , indole test , motility test , citrate test, and test O/F. It
could be concluded that 22.22 % of farmed nile tilapia in Lake Tondano were
infected with the Aeromonas sp with the following percentage from each site:
Paleloan village 7.40% , 7.40% Toulimembet village, and 7.40% Eris village.
