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. Keywords: Aeromonas sp, isolation, nile tilapia, floating net cage, Lake Tondano

Abstract

The objective of this study was to determine the growth of seaweed Kappaphycus alvarezii cultivated with Eucheuma denticulatum with different composition. This research was carried out for six weeks, from March to April 2013, in the coastal waters of Sondaken village, Tatapaan District, South Minahasa regency, North Sulawesi. The experiment was designed according to completely randomized design with four treatments and three replications. The four tested treatments were the different composistion of tied seaweed in a long-line raft, where treatment A: 100% K. alvarezii, ; B: 50% K. alvarezii and 50% E. denticulatum, on each culture line, two types of algae were tied in sequence; C: 75% K. alvarezii and 25% E. denticulatum, in which in each line, every three bunch of K. alvarezii was followed by one bunch of E. denticulatum; D: 25% of K. alvarezii and 75% E. denticulatum, on each culture line, every three bunch of E. denticulatum was followed by one bunch of K. alvarezii. Each experimental unit was a 3m x 3,4m rectangular line raft containing four culture lines where the bunch of the tested seaweed were tied. Data collection was performed every two weeks by weighing the tested K alvarezii. The data were statistically analyzed (ANOVA) using JMP statistical program (SAS-institute). The results showed that absolut growth, relative growth and daily growth rate of K. alvarezii was not significantly affected by the tested treatments (Prob> F > 0.5). Thus, the occurence of E. denticulatum in whatever abundance in K. alvarezii cultivation area will not affect the growth of K. alvarezii. Keywords: Seaweed, K. alvarezii, E. denticulatum, growth
