    Opis:
    This research aims to determine the effective dosage of potassium diformate (KDF) in feed to enhance sangkuriang catfish immune performances. The research was conducted on November - January 2019, at Aquaculture Laboratory Building No. 4 Faculty of Fisheries and Marine Sciences Universitas Padjadjaran. This study used an experimental method of Completely Randomized Design (CRD), with four treatments and three replications. The treatments are the addition of potassium diformate into feed with doses A (0%), B (0.5%), C (0.7%) and D (0.9%). Observed parameters are clinical symptoms, total leukocyte count, total erythrocyte count, specific growth rate, survival rate and water quality. The results showed that 0.5% KDF feed produced the highest survival rate of 85% and the highest specific growth rate of 3.59% after 40 days. Furthermore, due to treatment, total erythrocyte count increased from 2.09×106 cells/mm3, to 2.10×106 cells/mm3 (8.1%) and total leukocyte count increased from 7.1×104 cells/mm3, to 10.7×104 cells/mm3 (42.81%). The addition of 0.5% KDF in feed is effective in improving the immune performances of sangkuriang catfish challenged by A. hydrophila, with the highest survival rate of 97%. Moreover, recovery of total leukocyte count and total erythrocyte count was faster than other treatments as of day 7th, with a value 1.97×106 sel/mm3and 12.60×104 sel/mm3. It also resulted in the lowest gross clinical signs and the fastest recovering.

    Opis:
    The purpose of this study was to distinguish histopathological changes in carp fish (Carassius auratus) infected by Aeromonas hydrophila with different densities. Five treatments were used in the survey for this research method. The treatments used were bacterial infusion of A. hydrophila in the test fish through intramuscular injection with various densities, namely: A. without infection, B: 105 CFU/mL, C: 106 CFU/mL, D: 107 CFU/mL, and E: 108 CFU/mL. The parameters observed were histopathological changes in gill organs, kidneys and hearts of carp fish (gold fish). Data from histopathological observations were analyzed descriptively. The results present gill organs, liver and kidneys of carp fish infected with the bacteria A. hydrophila at various densities experiencing histopathological changes in the form of hemorrhages, necrosis and congestion and hyperplasia of the renal tubules. Other changes that occur were in the kidney organ experiencing a melanomacrophage center (MC). Tubules were coated with connective tissue and lymphocyte infiltration. The most severe organ damage that occurs in carp fish infected with the bacteria A. hydrophila at a density of 108 CFU/mL (treatment E) is shown by a low survival of 5%.

    Opis:
    Using water hyacinth as a phytoremediation agent produces abundant biomass due to periodic harvesting in the system. One of the alternative uses of water hyacinth biomass can be a bio-sorbent to absorb metal contamination in the waters. This study aims to determine the quality of activated water hyacinth bio-sorbent, potentially reducing metal cadmium (Cd). The research was conducted from January to April 2022. The results showed that the parameters of water content, iodine absorption, and methylene blue in water hyacinth bio-sorbent had met the quality standard of activated carbon based on SNI No. 06-3730-1995. In contrast, the ash content still did not. In water, hyacinth stem bio-sorbents (stems + ZnCl2 and stems 300 °C + ZnCl2) obtained higher ash content (25.87 and 73.30%) than the ash content of water hyacinth root and leaf bio-sorbent with the same activation treatment. The optimum adsorption capacity (Qe) for the roots + ZnCl2 occurred at a contact time of 45 minutes which was 8.13 mg/g with an absorption efficiency (Ef) of 34.20%. For the root 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours, namely 9.08 mg/g and 38.66%, respectively. The optimum adsorption capacity and absorption efficiency of the leaves + ZnCl2 occurred at a contact time of 4 hours, namely 7.63 mg/g and 32.12%, respectively. Meanwhile, at the leaves 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours with a value of Qe = 11.84 mg/g and Ef = 49.35%.

    Opis:
    The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1, 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.

    Opis:
    Goldfish is one of the most famous ornamental fish because of its body shape and color which was interesting to be maintained. The purpose of this research was to find the optimum dose of pumpkin and carrot flour combination on artificial feed to increase color brightness of goldfish. Complete Randomized Design with four treatments and four replications were used in the experiment. For the treatments, pumpkin flour 15%, pumpkin flour 7.5% with carrot flour 2.5% and carrot flour 5%, were studied. The parameters observed were color intensity, survival rate, and water quality. The results showed that supplementation of combination of pumpkin flour 7.5% with carrot flour 2.5% gave the highest color intensity of goldfish with TCF code 0815 and score 2.11 with 100% survival rate. Water qualities during the research were still in optimal condition.
