Abstract Marine and fisheries sector is one of the mainstay in the development of fisheries resources in Indonesia. Based on the fishery habitat fishery is divided into sea water, brackish water and freshwater. One result of freshwater fisheries potential that koi (C. carpio). Many of the obstacles that often harm the koi fish farming in producing a quality product. One of the obstacles which have a negative impact is a disease of fish. One type of disease most often a constraint due to the temperature of water in the koi fish is Ichthyophthiriasis. Parasiter disease in fish is caused by ectoparasites attack I. multifiliis. Artificial mode of transmission can be done to transmit I. multifiliis is by cohabitation which is an effort to pass the sick fish to healthy fish in a spot of maintenance. The existence of infestation I. multifiliis of fish will show clinical symptoms, degree of infestation and different intensity. This study aims to determine the degree of infestation and intensity I.multifiliis in fish koi (C. carpio) by the cohabitation method. The research method used was experiments method in the field carried out for cohabitation. Experimental method is a way to find a causal relationship (clause relations) between the two factors are intentionally inflicted by the researchers to eliminate or reduce and set aside other factors that could interfere (Arikunto, 2002). The results of this study indicate that the degree of infestation I.multifiliis on koi (C. carpio) during cohabitation indicate a mild degree of infestation, the degree of infestation and degree of infestation is heavy because the fish have different chances of infestation. Intensity I. multifiliis from day to day during the study experienced an increase ranging from 5,3 to 8,5 fish parasites every fish parasites.

Abstract Feed plays an important role in fish farming. Feed requirements achieve 60-70% of the cost of fish farming operations. Availability of feed with quality and sufficient quantity is aimed in increasing fish production. A very high feed prices due to artificial feed ingredients used are expensive and required in large quantities. Therefore, it is necessary to find alternatives to fish directly or indirectly obtaining appropiate and adequate nutrition needs to grow. The raw material content used for feed is coconut dregs (Cocos nucifera). The availability of the coconut dregs is abundant and potensial for fish feed ingredients. The coconut dregs is also one type or plantation waste which still has potential to be processed into the manufacture of fish feed. The coconut dregs flour can be processed by fermentation to improve quality. This study was aimed to determine the increase in crude protein content and a decrease in crude fiber content of coconut dregs fermented with Trichoderma viride; Bacillus subtilis and EM4. The research method was an experiment with Completely Randomized Design (CRD). The treatments used without the addition of microbes (P0), Bacillus subtilis 6% (P1), Trichoderma viride 6% (P2), and EM4 6% (P3) with 5 repeatitions each. The parameters observed were the content of crude protein and crude fiber after 7 days of fermentation. Data analysis used Analysis of Variance (ANOVA) and to determine the best treatments using Duncan Multiple Distance Test with 5% confidence interval. The results indicated that coconut dregs fermented with Bacillus subtilis (P1), Trichoderma viride (P2), and EM4 (P3) produced the difference of crude protein and fiber. The best treatment on the increase in crude protein content was Bacillus subtilis (P1) of 7.5564%. The best treatment on the decrease in crude fiber content was EM4 (P3) of 22.3967%. However, the results of the flour fermented coconut dregs can not be used as an alternative feed material because the fermented coconut dregs is not qualified for fish feed. This is due to a lack of crude protein and high crude fiber content.

Abstract Fish meat is more nutritious source of protein and relatively safe for human consumption. Fish meat more easily damaged than red meat product quality, so it is necessary that the process of pickling fish maintained in fresh condition and suitable for consumption. The ethanol extract of red algae Kappaphycus alvarezii been known have antioxidant and antimicrobial effects, so need some research on the use of red algae extract as a preservative. Red algae extract with a concentration of 400 ppm, 500 ppm, 600 ppm and 1 % formalin, each sample is used as a meat preservative for tilapia fillets as 40 grams. Samples of tilapia meat is soaked in an preservative solution as long as 60 minutes. During immersion, the samples of tilapia meat stored at room temperature. Observation of tilapia meat quality is done about six hours after meat removed from the preservative solution. Fish meat quality were analyzed to describe the organoleptic quality, methods of the TPC, and proximate analysis. The results showed that the ethanol extract of red algae Kappaphycus alvarezii 600 ppm has potential as a natural preservative based on test results of TPC, proximate and organoleptic test.

Abstract Red tilapia is kind of freshwater culture fish is quite popular because it has several advantages compared with other types of freshwater fish. To fullfil the demand of red tilapia can be overcome by cultivation. Effort to increase the production of red tilapia is to improve the quality of feed. The purpose of this study was to try the effect of the use of sword bean seed meal on the growth rate, survival rate and feed efficiency of red tilapia. The research method is experimental with completely randomized design (CRD) with five treatments and four replications. The treatments used were: (A) sword beans seed meal at 0% and soybean meal by 50%, (B) 10% sword beans seed meal and 40% soybean meal, (C) 20% sword beans seed meal and 30% soybean meal, (D) 30% sword beans seed meal and 20% soybean meal and (E) 40% sword beans seed meal and 10% soybean meal. The main parameters that measured were growth, survival rate and feed efficiency. Secondary parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to know the difference between treatments using Duncan's Multiple Range Test. Results showed the administration of sword bean seed meal on feed rations provide a significantly different effect (p<0.05) on the growth and feed efficiency but not significantly on survival rate of red tilapia (p>0.05 ). Highest daily growth rate obtained on treatment B on feed containing 10% of sword bean meal (1.20 %) was significantly different than treatment A (1.02 %), C (0.88 %) , D (0.85 %) and E (0.75 %) . Lowest daily growth rate was treatment E that significantly different with treatment A and B but not significantly different with treatments C and D. Highest feed efficiency obtained on treatment B (30.29 %) was not significantly different than treatment A (27.56 %), C (25.95 %) and D (27.78 %). Lowest feed efficiency was treatment E (17.84 %) significantly different than treatment B. Subtitution of sword bean seed meal in feed rations gave result that was not significantly different effect on the level of survival of red tilapia. Water quality of red tilapia rearing media was temperature range between 25-28° C, pH 7-8, dissolved oxygen 2-5 mg/L and ammonia 1.5 to 3.0 mg/L.

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.

Abstract Based on the food habits, gurami is omnivorous fish that feed herbivorous carp tend consists of natural food and artificial feed (pellets). The feed is needed to support the growth and survival of Gurami. If feed is given in accordance with the eating habits of Gurami and contain high nutritional Gurami can then growth accelerated faster. Some types of bacteria found in the digestive tract of animals has an important role in order to improve feed utilization, fish health, and environmental quality improvement and microorganisms. In addition, some bacterial flora in the gastrointestinal tract plays an important role and produce several types of enzymes in the digestive tract may contribute to the metabolism of the host. The purpose of this study was to determine the bacteria in the digestive tract of Gurami (Osphronemus gouramy) were given three different types of commercial feed. This study begins with a sampling of Gurami (Oshpronemus gouramy) of maintenance in the Faculty of Fisheries and Marine at Airlangga University in Surabaya and then do stage isolation and identification of bacteria in laboratory bacteria and Microbiology, Faculty of Veterinary Medicine, Airlangga University Surabaya. This study was conducted in July 2013. This research is a descriptive study, the method of solving the problem by describing the subject matter into a form that is easy to understand and based on facts. Results of research on gurami fish that given by three different types of commercial feed, there are two types of bacteria that dominate in the digestive tract of carp, the Pseudomonas sp. and Serratia sp. Both types of bacteria has the potential to help the digestive system of gurami fish. The result of this research are need for further research using the bacterium Pseudomonas sp. and Serratia sp. as probiotics.
