The objectives of research were to evaluate the effect bakasang-supplemented commercial diet on nile tilapia growth and to find the optimum dosage of bakasang to be supplemented in feed. The research was conducted at Laboratory of Nutrition and Fish Feed Technology. Fish weighing 0,9-1,7 g were palced in 15 aquaria at a density of 10 individuals/aquarium. Experimental design was complete randomized design with five treatments namely A (0% bakasang), B (2% bakasang), C (3% bakasang), D (4% bakasang), E (5% bakasang), each with three replications. Fish were fed three times a day as much as 5%/body weight. Growth of fish was observed every week. Research results showed that the lowest absolute growth, relative growth and feed efficiency were observed in treated with 0% bakasang (êG=20.44 g; GR=148.08%; dan NEP=58.06%) while the highest was obtained in fish treated with 4% bakasang (êG=35,55 g; GR=262.17%; NEP=80.53%). Analysis of variance displayed the use of bakasang significantly affect absolute growth, relative growth. It was concluded that feed supplemented with 4% bakasang gave better absolute growth, relative growth and feed efficiency as compared to other feed.

This paper was the result of a feasibility analysis of Talengen Bay Waters for aquaculture of Kappaphycus alvarezii. Feasibility analysis of water was based on the environmental data and water quality parameters of Talengen Bay. One mistake in the development of aquaculture is environmentally unsuitable. In order to develop aquaculture properly, appropriate water conditions data were required. Suitable aquatic environments are required by organisms for their survival because they are related to the patterns and behavior of the biota. In connection with the problems of mariculture at Talengen Bay, several efforts were required to overcome them. One of the efforts was made through this study that was assessment of appropriate location for the cultivation of seaweed. Talengen Gulf was located in in the territory of Kampung Talengen and Kampung Bunga Lawang, Central District of Tabukan, Sangihe Islands Regency, North Sulawesi. Laboratory analysis was conducted at the Laboratory of Industrial Baristand Manado. Determination of research stations done intentionally (purposive sampling). Based on the results obtained it could then be concluded that the condition of the aquatic environment and water quality parameters in the Talengen Bay were categorized as suitable for seaweed cultivation K. alvarezii.

The purpose of this study was to examine the effect of fish silages, bakasang as an immunostimulant in eel (Anguilla marmorata) feed against Aeromonas hydrophila infection. Three hundred elvers with the size of + 10 cm taken from Freshwater Aquaculture Institute (BBAT) Tatelu. The elvers were placed into 4 glass aquarium, each equipped with aerator and 1 for stock. Prior to the study, the eels were acclimatized for two weeks in order to adapt to new environmental condition. Two sets of researches were done: feeding the eels with additional bakasang with different doses for 6 weeks, which then further were challenged with Aeromonas hydrophila by immersion method. This study used a completely randomized design (CRD) with 4 treatments A (0 mL /kg diet), B (50 mL/kg diet), C (100 mL/kg diet), D (150 mL/kg diet). The growth data was taken by measuring the weight and length of the eels at the end of the period of feeding treatment while the mortality data of the eels were observed for 10 days after challenge test. The results of analysis of variance showed that the resistance of the eels in treatment B (50 mL/kg diet), C (100 mL/kg diet) and D (150 mL/kg diet) significantly different compared with treatment A. However, among the treatments B, C and D, there were no significant differences. Furthermore, the best eel growth was observed in treatment B with an absolute growth of 1.14 g, followed by treatment of D with an absolute growth of 1.04 g. In treatment A the absolute growth was only 0.82 g while treatment C was 0. 88 g. This suggests that the addition of bakasang in eels feed can promote the growth of eels as well as resistance against pathogen infection, thus served as immunostimulant.

A research had been conducted to evaluate the use of baker’s yeast as immunostimulant in enhancing the resistance of carp (Cyprinus carpio L) to Aeromonas hydrophila infection. Experimental fish were obtained from Freshwater Aquaculture Board in Talelu, Minahasa Regency, and transported to the Laboratory of Aquaculture Technology at the Faculty of Fisheries and Marine Science, Sam Ratulangi University. During two weeks of acclimatization process, fingerlings were fed with commercial feed (pellet) at 5% of body weight per day, twice a day. After acclimatization, fish was randomly distributed into 15 aquaria with a density of 25 fishes/aquarium. The doses of yeast cells as treatments included 5, 10, 15 and 20 g yeast/kg of pellet while control pellet not supplemented with yeast cell. Fish was fed with treatment pellets for four consecutive weeks at 5% of body weight per day, twice daily at 09.00 am and 16.00 pm. Afterward, the density of fish were adjusted to 10 fish/aquarium. Fish were then challenged with A. hydrophila through intraperitoneal injection of 0.2 mL of A. hydrophila suspension containing 1x107 cfu/mL. Research result showed that supplementation of yeast cells into fish pellet significantly influenced the resistance of fish to A. hydrophila infection (p<0,01). The highest resistance were observed in fish fed pellet supplemented with 5 g yeast/kg of pellet. Thus, supplementation of baker’s yeast cells into commercial fish feed was able to increase resistance of carp to A. hydrophila infection.

The effect of baker’s yeast as immunostimulant on innate immunity of carp (Cyprinus carpio L) had been investigated. Fish was gathered from Freshwater Aquaculture Board (BBAT) Tatelu, Province of North Sulawesi. The fish were acclimatized for a week in 15 aquariua with a density of 25 fish/aquarium. After acclimatization the fish were fed pellet supplemented with baker’s yeast as immunostimulant at 0, 5, 10, 15 and 20 g / kg of feed for four weeks as much as 5%/body weight of fish/day with the frequency of feeding twice a day at 08.00 am and 16.00 pm . This study used Completely Randomized Design (RAL) with five treatments and each treatment had three replications. Immune parameters consisting of total leucocytes and phagocytosis activity were measured in the last week. After four weeks of feeding, the total leukocytes from the carp fed with the addition of baker’s yeast 10 g / kg of feed were significantly increased compared with the fish not being fed with the addition of bread yeast (p <0.01). Phagocytic activity of phagocyte cells from carp also increased significantly in fish fed pellet with the addition of 5 g of baker’s yeast / kg of feed (p = 0.01). In conclusion, the addition of baker’s yeast as immunostimulant in the diet at 5-10 g/kg of pellet can increase the nonspecific immune response of carp.

The aims of the research were to find out firstly, the growth rate of the mud crab Scylla Serrata) reared under different salinity levels and secondly, the range of the salinity where the mud crab optimally grows. The experiment was conducted at the Laboratory of Aquaculture Technology, FPIK, UNSRAT, from April to May 2017. The experiment was set up according to the Randomized Block Design, with 3 treatments, which were 3 different salinity levels, 10 ppt, 20 ppt and 30 ppt. The tested level of salinity was determined based on the preliminary experiment. Each treatment was triplicated, and each replicate represents the group of the initial weight of the tested crab, which was 80-89 grams (group-1), 70-79 grams (group-2), and 60-69 grams (group-3). The tested mud crabs were collected from the estuarine waters of Inobonto river, which has salinity level of 12 ppt. The tested crabs were weighed at the beginning and at the end of the experiment, and at the interval of 7 days during the experiment period. The weight of the tested crabs data were converted into Absolute Growth Rate (AGR) and Daily Growth Rate (DGR), which in turn were statistically analyzed using Anova for Randomized Block Design, and then Least Significant Difference Test. The results of the Least Significant Difference Test show that the absolute and daily growth rate of the tested crabs in the salinity of 10 ppt are not significantly different with those in the salinity of 20 ppt. While the lowest absolute and daily growth rate of the tested crabs were in the salinity of 30 ppt and are significantly different with those in the salinity of 10 and 20 ppt. Hence, in order to get a maximal production, the mud crab, Scylla serrata, should be cultured in the waters with a range of salinity between 10 and 20 ppt.Keywords: Mud crab, salinity, growth
