One conventional method that usually done when the organism infected by pathogenic bacteria is using antibiotics, either with single or combination usage. However, the misuse of antibiotics dosages leads to resistance development of pathogenic bacteria. This study aims to determine the antibiotic resistance level of Vibrio spp. which was isolated from the waters of North Bali and to investigate the difference of resistance level between Vibrio spp. isolated from the cultivation area and outside the cultivation area. This research was conducted at the Microbiology Laboratory of BKIPM Denpasar and the Laboratory of Fisheries at the Faculty of Marine Science and Fisheries, Udayana University from November 2019 to February 2020. Antibiotic tests were carried out in vitro using 8 types of antibiotics namely tetracycline, oxytetracycline, enrofloxacin, ciprofloxacin, amoxycillin, doxycycline, ampicillin, and erythromycin with different concentrations of 0.5, 1, 2, 4, 8, 16, 32, 64, 64, 128, 256 and 512 ppm. and this test was carried out using a microplate reader to obtain absorbance values before and after incubation to determine the level of resistance of isolated Vibrios. The research showed that overall minimum inhibitory concentration (MIC) of Vibrio was below 100 ppm while the Vibrio spp. isolated from cultivation area have higher resistance level compared to outside cultivation area.

This research aimed to determine the ability of quorum sensing inhibitor compound thiophenone to protect catfish (Clarias sp.) larvae when challenged with the pathogenic Aeromonas hydrophila. This research was conducted at Fisheries Laboratory, Faculty of Marine Science and Fisheries, Udayana University, from December 2019 to January 2020. The experiment was setting up with four treatments and three replications for each treatment. 10 larvae of catfish were maintained in aquarium 15 cm × 15 cm × 20 cm filled with 1 liter of freshwater and used aeration for oxygen supply. The treatments were treatment A (control), treatment B (addition of A. hydrophila 106 cfu/ml), treatment C (addition of thiophenone 10 µM), and treatment D (addition of A. hydrophila 106 cfu/ml and thiophenone 10 µM). The results showed that the addition of thiophenone 10 µM increased the survival of catfish larvae up to 73% when challenged with A. hydrophila. That was significantly difference (P<0,05) compare to treatment B with survival rate of 43% within 3 days of culture period. Although it was not statistically different (P>0,05), the highest absolute weight and length were found in treatment A of 0,47 g and 0,50 cm, respectively, while the lowest absolute weight and length were found in treatment B about 0,23 g and 0,17 cm, respectively. The water quality such as temperature, pH and DO were still within the range that supported the growth and survival of catfish larvae during this study.

Addition of different fertilizer concentrations into cultivation media affects the cell density of microalgae. Potassium nitrate (KNO3), is one of the components in Guillard fertilizer composition commonly used for microalgae culture. This study aims to determine the quality of Chaetoceros calcitrans when cultured with different concentration of KNO3. This research was conducted from November 2019 to January 2020 at Balai Perikanan Budidaya Air Payau (BPBAP) Situbondo and Biosain Laboratory, Jember State Politeknik, East Java. This study consists of four treatments and three replicates. The object in this study was C. calcitrans culture with initial density 105 cells/ml. The main parameters observed were cell density, biomass, protein and amino acids contents and medium parameters such as temperature, pH, DO, salinity, nitrate and phosphate. There were four concentrations of KNO3 used in this study, namely control (75 g/l), treatment Group A (100 g/l), treatment B (125 g/l) and treatment C (150 g/l). The results showed that the cells density of C. calcitrans at control, treatment Group A, B and C were 110.4; 105.2; 108.3; and 100.8 (×104 cells/ml), respectively. This study indicated that different concentration of KNO3 affect the starting point of stationary phase, but One Way ANOVA test showed that those treatments had no significant effect (P?0,05) on the growth rate and dry biomass of C. calcitrans. Finally, we found that the protein content in addition of 75, 100, 125 and 150 g/l KNO3 were 9.748; 8.802; 6.812; and 3.776%, respectively.

Aquaculture is an activity to cultivate aquatic biota in controlled media. One of the cultivated fish resources is tilapia (Oreochromis niloticus). Tilapia production continues to be increasing to meet increasing of consumer demand. The emergence of the problem of organic matter levels in the water could be harmful to both of fish and the environment. One of the solution to overcome this problem is by application of biofloc technology. The purpose of this study was to determine the diversity and composition of plankton species in tilapia biofloc ponds in Tiga Village, Susut District, Bangli Regency. This research was conducted in March-May 2021 in Tilapia Biofloc Pond. The research used a simple random sampling method. Sampling was carried out once in three biofloc ponds where each pond had 5 points. Data analysis is using the Microsoft Excel program. The data is present in the tables and charts consisting of the abundance, diversity, composition, dominance, and uniformity index of plankton. Based on the research results, it is known that there are 12 genus of phytoplankton and 4 genus of zooplankton. Phytoplankton diversity index values ??ranged from 1.31 to 1.65. Zooplankton diversity index values ranged from 0.79 to 1.08. The composition of phytoplankton species came from the genus Scenedesmus, Chlorella, Coelastrum, Chroococcus, Gonatozygon, Pediastrum, Nitzschia, Navicula, Synedra, Triceratium, Chaetoceros, and Pesudanabaena. The composition of zooplankton species comes from the genus Brachionus, Euchlanis, Tokophyra, and Vorticella. The water quality measured during the study was a temperature value ranging 25 oC, a pH value ranging from 7,12 – 7,18, a DO value ranging from 6.6 to 6.9 mg/L, an ammonia value ranging from 1.41 to 1.51 mg/L, and a nitrate value ranging from 1.84. -3.69 mg/L. This value is still in the optimal range for plankton life.

Vannamei shrimp (Littopenaeus vannamei) known as white shrimp is widely cultivated in Indonesia because it has high economic value. Conventional cultivation of vannamei shrimp is often represented by poor sewage treatment, where aquaculture waste is discharged directly causing a decrease in water quality in the environment. This study used 2 different cultivation systems, namely RAS (Recirculating Aquaculture System) and conventional systems (flow-through system). The research located at BPIUUK Karangasem, Bali. Water quality monitoring in each tank was carried out including ammonia, nitrite, TSS (Total Suspended Solid), and the abundance of microbes. Measurement of weight and length starts from the age of 30 days of shrimp with further checks every 7 days. A sampling of water quality, as well as measurements of weight and length, were carried out by random sampling method in each rearing tank. Based on the research data, the quality of aquaculture water using RAS and conventional system were not significantly different. The data on the abundance of microbes obtained in cultivation using RAS and conventional were also not significantly different, where RAS reaching 2.0 x 105 cfu/mL, while in conventional system was obtained 2.1 x 105 cfu/mL of total bacteria count. The growth rate with the average value of ADG (Average Daily Growth) in RAS is 0.88 g slightly higher compared to it is 0.80 g in conventional system. This study concluded that cultivation using RAS and conventional by flow-through system were not significantly different in terms of water quality, microbial abundance, and shrimp growth rate.

Abalone is one of the sea snails that have high economic value and has advantages because it has a high protein content of 71.99%, a fat content of 3.24%, and can be used as medicine. The high demand for abalone causes the increase of wild capture and lead to scarcity of abalone in the waters. One way to overcome this problem is by cultivate the abalone. Abalone cultivation can be done with a monoculture system. One of the technologies applied is by using a recirculation aquaculture system (RAS), which is reprocessing the water used so that it can be reused for cultivation activities. The purpose of this study was to analyze the parameters of water quality, growth length, weight and survival of abalone (Haliotis squamata) seeds using the RAS system. The research was conducted in June – September 2020 at the Shrimp and Shellfish Parent Center, Karangasem, Bali. The research was performed by purposive sampling method. The water quality parameters data such as nitrite, ammonia, TSS pH, temperature, DO, and salinity were taken. The results of the measurement of water quality are nitrite 0 – 0.338 mg/L, ammonia 0 – 0.09 mg/L, TSS 0 – 15 mg/L, pH 7 – 8, temperature 26 – 28 oC, DO 4.3 – 7.07 mg/L, and salinity 31 – 38 ppt. Those values are still in the optimal range for abalone culture. The growth in length and absolute weight of abalone seeds during the study were 25.17 mm/ind. and 9.15 g/ind., respectively, and the survival value was 99.5% during the 100-day culture period.

Ikan kerapu adalah komoditas perikanan yang bernilai ekonomis tinggi pada pasar domestik dan internasional. Akan tetapi, dalam budidaya ikan kerapu masih sering ditemukan kasus penyakit vibrosis yang berdampak terhadap kerugian ekonomi akibat kematian yang ditimbulkan. Penyakit ini disebabkan salah satunya oleh bakteri Vibrio parahaemolyticus yang faktor virulensinya diregulasi oleh mekanisme kuorum sensing (QS). Pencegahan penyakit bakteri selama ini sering dilakukan dengan menggunakan antibiotik yang berisiko munculnya bakteri resisten antibiotik. Salah satu upaya untuk menghindari hal tersebut adalah dengan menghambat sistem QS menggunakan bakteri pendegradasi molekul sinyal N-acyl homoserine lactone (AHL). Pada penelitian ini dilakukan isolasi kandidat bakteri pendegradasi AHL pada media menggunakan AHL komersial sebagai sumber N tunggal dan juga melakukan isolasi bakteri V. parahaemolyticus pada media Thiosulfate-Citrate-BileSalts-Sucrose Agar dari saluran pencernaan ikan kerapu. Pengaruh penambahan isolat kandidat pendegradasi AHL terhadap tiga faktor virulensi V. parahaemolyticus yaitu motilitas, produksi kaseinase dan hemolisa diuji dengan mengkultur V. parahaemolyticus dengan dan tanpa penambahan isolat pendegradasi AHL. Hasil penelitian menunjukkan bahwa 2 isolat kandidat pendegradasi AHL yaitu SNA02 dan SNA03 mampu menurunkan ketiga faktor virulensi yang diuji tersebut. Hal ini mengindikasikan bahwa isolat SNA02 dan SNA03 berpotensi sebagai kandidat bakteri untuk mencegah penyakit vibriosis. Hasil ini diharapkan dapat membantu pembudidaya ikan kerapu dalam mengendalikan patogenitas bakteri V. parahaemolyticus.

Research on the benefits of Bacillus sp. in aquaculture has been done a lot. Currently, the aquaculture industry, especially shrimp farming, is facing AHPND disease, which is known to be caused by Vibrio parahaemolyticus. This study aims to see the effect of Bacillus sp. against virulence of V. parahaemolyticus in vitro using caseinase production as an indicator and survival of Artemia franciscana cultured axenically when challenged with V. parahaemolyticus. In in vitro tests, cultures of V. parahaemolyticus were grown with and without the addition of Bacillus sp. on Luria Bertani (LB) liquid media, and then the caseinase test was carried out using skim milk (SM) agar as a growth medium. In the challenge test, 10 axenic cultured Artemia sp. were distributed in falcon tubes containing 10 ml of sterile seawater. Challenge test treatments consisted of treatment A as control of Artemia culture without the addition of bacteria, treatment B Artemia culture adding by 106 CFU/ml V. parahaemolyticus, treatment C Artemia culture with the addition of 106 CFU/ml Bacillus sp., and treatment D Artemia culture with the addition of 106 CFU/ml V. parahaemolyticus and 106 CFU/ml Bacillus sp. All treatments were done in triplicates. The results showed that the addition of Bacillus sp. was able to reduce the caseinase production of V. parahemolyticus up to 29% indicated by the decrease of the clearing zone diameter formed on SM agar. Furthermore, the addition of Bacillus sp. in treatment D was able to significantly increasing (P<0.05) of Artemia's survival when challenged with V. parahamolyticus. This indicates that Bacillus sp. has a potential as a probiotic candidate to prevent disease caused by V. parahaemolyticus.

Biofloc technology is used to overcome the increase in organic matter, improve the quality of aquaculture water, and increase production yields. This study aims to determine the growth rate and survival rate of African catfish with different stocking densities in the biofloc system. This study used a completely randomized design (CRD) with 3 treatments and 5 replications. The test animals used African catfish measuring 7-9 cm with a stocking density of A (15 ind/15L), B (20 ind/15L) and C (25 ind/15L). The results showed that the use of a biofloc system in African catfish culture with different stocking densities resulted in no significant difference in growth rate, survival rate (SR) and feed conversion ratio (FCR). The average weight growth value of African catfish in treatment A, B, and C was 14,13 ± 2,26 g, 13,37±0,46 g, and 12,04±0,48 g, respectively. The average length growth in treatments A, B, and C was 6,27±0,54 cm, 6,09±0,31 cm, and 5,69±0,34 cm, respectively. The survival value (SR) of African catfish in treatment A, B, and C was 85,33±5,58%, 83±2,73%, and 82,40±2,19%, respectively. The value of the feed conversion ratio (FCR) in treatment A, B, and C was 0,72±0,08, 0,75±0,06, and 0,79±0,03, respectively. The range of values for the water quality parameters of the culture media is categorized as suitable for the growth of African catfish, resulting in temperature, DO, and pH value of 27,5-30,8°C, 3,9-5,9 mg/L, pH 6,20-6,45, respectively. The content of ammonia is 0,26-0,44 mg/L, nitrite is 0,08-0,18 mg/L and nitrate is 0,18-0,29 mg/L.
