    Opis:
    This study aims to determine the method of generating water flow inside a round container to increase the survival and growth of common carp fingerlings. The approach used in this research is an experimental method which applies a Completely Randomized Design (CRD) and consists of three and five replications. The treatments used are (A) No Water flow (control), (B) 0.1 m/s of water flow, (C) Water flow utilizing an additional venturi system. The test fish used were 450 majalaya common carp of size 3-5 cm. The containers used in this research are in the form of 15 gallons capacity with a diameter of 27 cm x 36 cm height x bottom diameter of 6 cm containing 19 liters of water. The density of common carp during the study was 30 carp per treatment container. The treatment period is 40 days. The food given is 5% of the bodyweight of fish. Water quality parameters (temperature, pH, dissolved oxygen, ammonia and nitrates) were observed every 10 days for 40 days. Other parameters are survival, daily growth rate, feed conversion ratio, and feed efficiency observed every 10 days for 40 days. The results showed that the use of water flows with the venturi system provides the best results - with a life growth rate of 1.5%, a feed conversion ratio of 3.18, feed efficiency of 31.73% and 75% survival.

    Opis:
    This study aims to determine the best density of Bacillus sp. which is given through feed to increase the body resistance of carp that is infected by pathogenic bacteria, Aeromonas hydrophila. The research was conducted at the Aquaculture Laboratory and Laboratory of Microbiology and Biotechnology at FPIK UNPAD. This study used an experimental method with a completely randomized design consisting of 4 treatments and 3 replications, namely treatment A (control), treatment B (Bacillus sp. 106 cfu/mL feed), treatment C (Bacillus sp. 108 cfu/mL feed) and treatment D (Bacillus sp. 1010 cfu/mL feed) for two weeks later in Aeromonas hydrophila infection with an intramuscular density of 108 cfu/mL for seven days. Observation parameters were clinical symptoms, fish response to feed, fish response to shock and survival. The results of this study showed that treatment C (Bacillus sp. 108 cfu/mL feed) resulted in 89% survival and reduced clinical symptoms.

    Opis:
    Fish are aquatic animals, where they share the same ecosystem with the bacterial community they are associated with. Community structure is a concept that studies the composition of species and their abundance in a community. Information related to bacterial communities associated with their hosts is very important to support fisheries resource management efforts, both through nature conservation and aquaculture. This study of the bacterial community in the digestive tract of fish can be used to support further utilization of potential bacteria that can be used to improve the fish's immune system. This research was conducted to analyze the structure of the bacterial community found in the intestines of Common carp through a metagenomic approach using the NGS (Next-Generation Sequencing) method. The method used is a metagenomic approach, including DNA isolation from Common carp intestines. Then molecular identification was carried out using Illumina's NGS (Next-Generation Sequencing) method using the 16S rRNA gene marker. The results of the analysis using the NGS method showed as many as 19 types of bacterial phyla identified with the top three phyla, namely Fusobacteria (80%), Bacteriodetes (15%), and Firmicutes (3%). The phylum Fusobacteria is dominated by the genera Fusobacterium, Propionigenium, Ilyobacter, Leptotrichia, and Sebaldella. The phylum Bacteriodetes is dominated by the genera Porphyromonas, Odoribacter, Bacteroides, Sphingobacterium, and Barnesiella. The phylum Firmicutes is dominated by the genera Clostridium, Lactococcus, and Sarcina, Bacillus, and Lactobacillus.

    Opis:
    The research was conducted at the Aquaculture Laboratory of the Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Jatinangor. The purpose of this research is to determine the optimum temperature for the maintenance of Common carp strain Majalaya fingerlings based on resistance to temperature stress that is known through their blood profile and survival rate. Common carp strain Majalaya fingerlings originating from Ciparay, West Java. Total body length is 8-12 cm with a minimum weight of 10 g. The method used is experimental with a completely randomized design (CRD) consisting of three treatments and five replications. The fish are kept at 24 ºC (control without heater), 29 ºC and 34 ºC. Each experimental unit contains 10 fishes. The results obtained by the survival rate (SR) of Common carp strain Majalaya which were maintained at a treatment temperature of 24 ºC by 100%, the 29 ºC by 70%, the 34 ºC by only 42% remained on the 21st day. The number of erythrocytes of common carp strain Majalaya fingerlings before the treatment temperature was 2.77 × 106 cells/mm3. The average number of erythrocytes of the 24ºC treatment from 7th, 14th and 21st day were 2.82, 2.82 and 2.81 × 106 cells/mm3; the 29 ºC were 2.93, 2.68 and 2.42 × 106 cells/mm3; the 34 ºC were 3.08, 2.52 and 1.99 × 106 cells/mm3. While the number of leukocytes of common carp strain Majalaya fingerlings before the treatment temperature was 13.61 × 104 cells/mm3. The average number of leukocytes of the 24 ºC treatment from 7th, 14th and 21st day were 13.73, 13.71 and 13.88 × 104 cells/mm3; the 29 ºC were 18.40, 16.46 and 15.76 × 104 cells/mm3; the 34 ºC were 20.78, 18.46 and 16.81 × 104 cells/mm3.
