Abstract African catfish (Clarias gariepinus) is a type of freshwater fish consumption with elongated body and smooth skin. Bacterial disease that often strikes African catfish and can cause death as well as a cause of primary infection is A.hydrophila. Bacterial infection may be one cause of the synthesis of lipid peroxidation which is an indication of the emergence of free radicals. And the end result of lipid peroxidation is malondialdehyde. Sprouts are the new little plants grow from seeds planted beans. Green bean seed germination will enrich vitamins including vitamin E, green beans or α-tocopherol. Vitamin E in maintaining the stability of the plasma membrane and protects the cell structure against damage caused by free radicals is by blocking the reaction initiation and propagation of lipid peroxidation reactions interrupt. Data analyze of this research was used Varian Analyze (ANAVA) and to found the lowest level was used Duncan Test. The average yield of malondialdehyde levels in the negative control treatment is 0.0386 ng / 100 mg mass, positive control (1 ml Aeromonas hydrophila 105 cfu per 5 liter) is 0.0962 ng / 100 mg mass, sprout extract treatment (0 , 1 ml per fish) is 0.05 ng / 100 mg mass, germination and pollen treatment Aeromonas hydrophila is 0.0626 ng / 100 mg mass. From these results indicate that the highest levels found in the positive control treatment while the lowest levels found in the negative control. These results also suggest that decreased levels of malondialdehyde using pollen germination is very significantly different with P < 0,01.

Abstract Gurami is a fish with a slow growth because of the efficiency of utilization of nutrients and energy contained in the feed is too slow, so it is not enough energy available for growth. Feed components that contribute to the provision of materials and energy for growth are proteins, carbohydrates, and fats. The ability of fish to use depends on the nutrient feed enzymes in the digestive organ. Enzyme producing bacteria to help digest fish feed with the help of enzymes produced by the bacteria are protease, lipase and amylase. Determination of Total Plate Count (TPC) has a population of principles that determine the amount of bacteria found in the digestive organ of fish, because the bacteria are the main factors that cause decomposition. The purpose of this study is to obtain total bacterial or Total Plate Count (TPC) in the digestive organ of Gurami (Osphronemus gouramy) given different feed. This study was conducted in July-August, 2013, in the Bacteriology Laboratory of Microbiology, Faculty of Veterinary Medicine, Airlangga University Surabaya. This research is a descriptive research method of solving the problem by describing the subject matter into a form that is easy to understand and based on facts. The results showed that the highest number of total bacteria in the stomach of each type of feed. However, if the average value is taken and compared between the feed is P1, P2 and P3 obtained an average highest number of total bacteria on P2 feed, the average number of bacteria in a row in P1, P2, and P3 are 71.8 x 107 ; 64.5 x 107; 2.9 x 107 which also has the highest crude fiber content of nutrients in the form of a percentage on the proximate test is 8.03%. Expected that the results of this study further research on the addition of probiotic bacteria in the gastrointestinal organ which will help of growth of carp.
