    The abundance of plankton in container pond with bottom podzolic red yellow soil on the basis of pond ages and CaCO3 liming
    (2013-06-07) Hadis, Abdul
    This research was conducted from October to November 2012 at Environmental Quality Cultivation Laboratory Fisheries and Marine Science Faculty of Riau University. The purpose of this study was to determine the abundance of phytoplankton in the podzolic red yellow soil (PMK) with difference age of ponds and limings by Boyd (1979). Experimental method was used and complete random design (CRD) was applied. The treatments consist of pond ages ranging from 0-5 years old for O1; 6-10 years for O2; 11-15 years for O3; 16-20 years for O4. The results showed that 13 species were found and it consisted of Chlorophytes (7 species), Cyanophytes (5 species), and Bacillariophytes (1 species). The peak population was found at 10th days on the treatment with liming meanwhile at 8th days on the treatment without liming in average; - They were 16.060 ind/l and 10.463 ind/l in average respectively. Furthermore, the highest abundance of phytoplankton can be seen on the treatment O4 (16-20 years old pond) both for liming and without liming. In conclusion, the older the pond with liming was better than the younger the pond without liming.

    A research on the effects of lactic acid bacteria injection on the survival rate of Epinephelus fuscoguttatus has been conducted from November until December 2011 in the Laboratorium of BBPBAP Jepara. The aims of the research was to understand the pathogenic effects of the lactic acid bacteria and to understand non- specific defense as well as survival rate of E. fuscoguttatus that were injected with the bacteria. Treatment applied was the different dosages of bacteria injection. Each fish was injected with 0,1 ml of lactic acid bacteria with 10 5 cells/ml, 10 7 cells/ml and 10 9 cells/ml densities. The treated fish were reared in 60 liter aquaria completed with aerators, 10 fish/ aquarium. The fish was feed ad libitum with commercial fish feed pellets. The fish were reared for 14 days and the clinical symptoms were checked daily. Before the injection and by the end of the research, survival rate, body weight increment, total length increment, leukocyte numbers, haematocrite and leucocrite levels were measured, while water quality parameters (pH, salinity, DO, temperature and ammonia content) were checked once/ 3 days. The best result was obtained in the fish that was injected with 10 9 cells/ml of lactic acid bacteria, as the survival rate was 100% and they showed highest increment of body weight (from 13,20 g to 16,20 g), total length (from 8 cm to 9,77cm), leukocyte number (from 89,270 cells/ml to 128,610 cells/ml), hematocrite level (from 22,3 % to 23,2%) and steady leucocrite level (1,0%). Water quality parameters indicate that the quality of the water quality during the research was good (DO 3,8 g/l – 4,3 g/l, temperature 26,2 0 C – 26,6 0 C, pH 7,6 – 7,8 , salinity 33 ppt and NH3 0,001 mg/l – 0,040 mg/l).
