Fresh water prawns are commodities freshwater fish that have economic value, particularly in Indonesia. As the development of tourism and a variety of culinary consumption in Indonesia fresh water prawns and open export opportunities. Fresh water prawns, high cholesterol is 385,03 mg/dl. Excessive cholesterol in the body will lead to a condition called atherosclerosis condition is the forerunner of heart disease and stroke. One of the efforts that must be undertaken to produce low cholesterol aquaculture products are engineered feed, supplementation with fatty acids derived from marine organisms. Through the fatty acid supplementation, it is expected that the levels of triglycerides and low density lipoprotein cholesterol (LDL) will decline so it can raise levels of high density lipoprotein cholesterol (HDL). Analysis of data using statistical test of Variant Analysis of variance (ANOVA) to determine the effect of treatment. If there are differences among the treatments continued with Duncan Multiple Range Test to determine the best treatment. Analysis of Variant (ANOVA) result a significant difference (p<0,05). The main parameters of total cholesterol, high density lipoprotein cholesterol (HDL) and low density lipoprotein (LDL) meat prawns tested at the Laboratory of Physiology, Faculty of Medicine, Universitas Brawijaya. Parameter supporters observed that the maintenance of water quality fresh water prawns.

Intensive aquaculture systems causing heavy reliance on the use of artificial feed (Heptarina et al., 2010). Feed is a crucial component to the success of shrimp farming (Soemardjati and Suriawan, 2006). According to Haryanto and Djajanegara (1993) lamtoro leaves contain protein, calcium and energy. The content of the leaves lamtoro a source of protein for feed ingredients in this plant are essential amino acids lysine and leucine were very high (D'Mello and Fraser, 1981). The consideration for the selection of feed materials should be done in accordance with the provisions of the feed material that is readily available, low cost, high nutrient content and do not compete with humans (Handajani et al., 2010). According to Matthew (1993), leucaena as forage quality has not been used optimally and not much commercialized. Lamtoro a potential biological resources to be used as feed to the waste generated sufficient forage nutritional value (Widiastuti, 2007). Research on the use of fermented flour substitution lamtoro leaf is a matter that needs to be done because of the use of fermented flour lamtoro leaf is expected to improve the quality of feed and make it as an alternative feed ingredient that can be given to increase aquaculture production. This research is the experimental method using a completely randomized design (CRD) with four treatments and five replications. The results of this study will be analyzed descriptively in the form of data and tables. Data obtained, processed using Analysis of Variance (ANOVA) to determine the effect of different treatments applied if real, then continued with Duncan's Multiple Range Test (Duncan's Multiple Range Test) with a 5% error rate to determine the best treatment.Â Keywords: Feed, Vaname Shrimp, Fermentation, Substitution, Leucaena Leaf, Protein Retention, Retention Energy.Â

Abstract The increase in value-added of fishery products is one of which can be done by processing. In addition to maintaining the value of the protein in the fish raw material, it would be easier if the product is stored and increase the sale value of the fish itself. The ability to perform in the fish processing in Mandangin island is still very limited. Community service activities that have been carried out by a team of the Faculty of Fisheries and Marine Universitas Airlangga was introduce smoked fish product processing with liquid smoke,because this method easier and faster so that the products can be marketed. Liquid smoke was developed because the location is very minimal in the supply of raw materials such as firewood and coconut, so the use of liquid smoke is very appropriate. The resulting refined products are expected to be a source of protein Mandangin Island community itself and is able to become an alternative source of income for the community to increase the sale value of fishery products. Mentoring process being conducted by a team from the Faculty of Fisheries and Marine Universitas Airlangga so that the products can be marketed outside Mandangin Island or even to other areas in East Java.

Abstract White shrimp are aquatic organisms consumed by many people and a source of animal protein and fat needed by humans. Shrimp also require fat as a source of energy and metabolic processes to maximize growth. White shrimp meat contains high cholesterol so that it becomes an obstacle to consume white shrimp and high cholesterol in feed can affect the growth of shrimp. This problem can be solved by adding Crude Fish Oil (CFO) which contain high omega-3 fatty acids in white shrimp feed to decrease cholesterol content and source of dietary fat to increase fat retention in meat. The research problem is whether the addition of CFO in white shrimp feed effect on the decrease cholesterol content and increase of fat retention in meat. This research aims to determine the effect of CFO in white shrimp feed to decrease cholesterol and increase of fat retention in meat. The method used is experimental method with Completely Randomized Design (CRD) as the experimental design. The treatment used is different persentage CFO addition to white shrimp feed, ie P0 (0%), P1 (2%), P2 (4%), P3 (6%) and P4 (8%) each treatment is repeated 4 times. Analysis of the data using Analysis of Varians (ANOVA) and to determine the best treatment performed Duncan's Multiple Range Test. Results showed that the addition of CFO in feed give significant effect (p <0.05) to decrease the cholesterol content in meat. The best average decrease of cholesterol content obtained at P3 (135.22 mg/100 g) and P4 (133.51 mg/100 g). Addition of CFO in feed did not give significant effect (p>0.05) to increase fat retention in meat.

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.
