Problems in cultivating milkfish are disease outbreaks and the high cost of feed. Therefore, a breakthrough is needed to overcome this problem by adding medicinal plants, namely aloe vera, to the feed. This study aims at determining the effect of adding aloe vera to artificial feed on the blood cell profile and growth of milkfish seed. The research method used was a complete randomized design with 4 (four) treatments and 3 (three) replications. The treatments on the test feed used were: A, (giving aloe vera as much as 0 g/kg feed), B (giving aloe vera as much as 5 g/kg feed), C (giving aloe vera as much as 10 g/kg feed), and D (giving aloe vera as much as 15 g/kg feed). The results showed that blood glucose values were still within the normal range. The lowest value in treatment was A, which was 42 mg/dL, and the highest in treatment was D, which was 66 mg/dL. The lowest Hb value was found in treatment A (5.1 g/dL), and the highest was 7.2 g/dL, found in treatment D. The highest average growth rate was obtained in treatment D with increasing biomass of 3.81g. While the lowest growth was obtained in treatment A which resulted in average growth of 2.06g. Water quality during the study was suitable for milkfish rearing media, namely temperature of 27 - 31°C, pH of 7.2 -,7,8, and salinity of 25 - 27 ppt.

The recent global increase in demand for catfish products has led to intensive catfish farming, favoring Aeromonas infections. Therefore, there is a need to enhance the current management method of Aeromonas infection in catfish. This study evaluated the efficacy of adding vitamin C to Oxytetracycline in the treatment of Aeromonas infection through the development of skin lesions, mortality and serum antioxidant defense system. One hundred and five juvenile catfish were randomly assigned to seven groups (n=15). The first group served as control and was neither infected nor treated, while the other groups were infected with Aeromonas hydrophila. Seventy-two hours after inoculation, catfish in groups 2-7 were treated as follows: no treatment, Oxytetracycline through bath, Oxytetracycline through feed, Oxytetracycline through bath with 500 mg of vitamin C in water, Oxytetracycline through feed with 500 mg of vitamin C in water and 500 mg of vitamin C only in water, respectively. The treatment was done for five consecutive days. Behavioral changes, clinical signs and mortality were observed. Data were presented as Mean±SD and analyzed using descriptive statistics or One-way Analysis of Variance (ANOVA) and Tukey's Test. p <0.5 were regarded as significant. The cumulative percentage mortality in groups (Groups 5 and 6) supplemented with Vitamin C was 26.7 and 33.3 compared to 90% and 46.6% in groups 2 and 4, respectively. The results showed that adding vitamin C to Oxytetracycline reduced the development of skin lesions and mortality. Therefore, Vitamin C is recommended to manage Aeromonas hydrophila infection in catfish.

Tilapia (Oreochromis niloticus) is a cultivated commodity that is widely developed because of its economic value and high nutritional content. However, in aquaculture activities, problems such as water pollution reduce water quality. This problem means continuous water changes to maintain water quality. A recirculation system can be a solution by reusing water. The use of filters is an important factor in a recirculation system. One alternative filter is chitosan derived from crab and shrimp shell waste. This study aims to determine the optimal concentration of chitosan as a recirculation filter. The study was conducted experimentally using a completely randomized design with four treatments and three replications. Each treatment is a variation of the concentration of chitosan as a filter. Analysis of measurements carried out was absolute weight growth, specific growth rate, survival, and water quality. Based on the ANOVA results, each treatment had a significant effect on the absolute weight growth of tilapia, P<0.05, with P3 being the most significantly different. At the same time, the specific growth rate and survival of tilapia did not significantly affect P>0.05. The water quality measurements showed that the temperature, pH, ammonia, and DO values were still by the quality standards of tilapia aquaculture, with P3 treatment, which gave better water quality results. Based on the study results, the optimal concentration of chitosan as a filter in supporting tilapia growth was in the P3 treatment, which was 50 mg.

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.

The production of vannamei shrimp (Litopenaeus vannamei) continues to decline due to parasitic attacks on ponds in North Gorontalo Regency. Ectoparasites are one of the factors that can cause failure in the cultivation of vannamei shrimp (Litopenaeus vannamei). This study aims to determine the type of ectoparasites, intensity, and prevalence of vannamei shrimp cultured in traditional ponds in the North Gorontalo Regency. A sampling of the research was carried out at five research stations. This research was selected randomly in 5 plots of ponds, and the total number of shrimp was as many as 150 tails. At each station, samples were taken of 30 vannamei shrimp (Litopenaeus vannamei). Sampling using fishing gear in the form of nets. The observed models were 8-10 cm in size alive. Observations of ectoparasites were carried out microscopically using a Zeis Binocular microscope with 10x magnification. Data analysis used descriptive analysis of ectoparasites, intensity, and prevalence of ectoparasites found. The study's results found four types of ectoparasites found in vannamei shrimp: Zoothanium sp, Epistylis sp, Carchesium sp, and Vorticella sp. The intensity of ectoparasite attack on shrimp was categorized as low to moderate infection, namely 4-7 individuals/head. The prevalence rate is 80-100%, with moderate to very severe disease.

A data acquisition system for measuring and storing dissolved oxygen levels has been implemented to monitor water quality levels in shrimp culture media using an internet-based potential redox sensor (ORP). The purpose of this study is to apply ARMS, an instrument for monitoring internet-based potential redox data (dissolved oxygen levels) in shrimp culture media in real-time to determine the condition of water quality. This system is designed using an ORP sensor that uses WIFI communication. In principle, when the ORP sensor is placed in the water in the shrimp culture media, the potential redox data will be detected by the sensor connected to the ESP8266 which processes and transmits data which is then displayed and analyzed on the smartphone interface. In this study, 9 units of shrimp culture media prototype ponds were used for observational tests. The object of observation in the pond is water quality data in the form of sediment potential redox values. At this stage of research, two processes of observation of data collection were conducted. The first process is to monitor water quality conditions on the user's smartphone display, in the form of the potential redox value of each pool measured by the ARMS instrument for 12 weeks. The second process is to compare the potential redox observation data measured by the ARMS instrument and the ORP Meter in each pool. Observation of comparative data took place during the 6th week. The sediment potential redox values for treatments 1, 2, and 3 were 69 mV, 151 mV, and 210 mV respectively. The average redox potentials in the water are in the range of 90.56 mV to -263 mV for treatment 1; 90.75 mV to -62,934 mV for treatment 2; 90.65 mV to 60.73 mV for treatment 3. This range is the measurement range from week 0 (shrimp seed stocking) to week 4. The results of the comparison of the two tools show that the accuracy of the ARMS tool is more than 95%.

The purpose of this study is to apply ARMS, an instrument for monitoring internet-based potential redox data (dissolved oxygen levels) in shrimp culture media in real-time to determine the condition of water quality. This system is designed using an ORP sensor that uses WIFI communication. In principle, when the ORP sensor is placed in the water in the shrimp culture media, the potential redox data will be detected by the sensor connected to the ESP8266 which processes and transmits data which is then displayed and analyzed on the smartphone interface.

Gambusia was studied in Oubeira lake in spring 2016. A total of 100 specimens were collected in the lake. The sex ratio was F:M = 5.12: 1. The length-weight relationship was estimated for the population, with Wt = 0.0197Lt2.4451. The condition factor was calculated C=1±0.2 (for population) and a significant difference was observed between males and females. For 100 examined stomachs, the diet mainly consists of algae (N=54.96%, Pi= 166%, O=91%), followed by the mosquito larvae (N=21.52%, Pi= 65%, O=49%), detritus (N=19.2%, Pi= 58%, O=46%) and arthropods (N=4.3%, Pi= 13%, O=13%). For mosquitoes, two genus were recorded: Culiseta and Culex with 4 species: Culex pipiens, Culex theileri, Culex laticinctus and Culex antennatus. The culture experiments confirmed the important predation on mosquito larvae was observed with feeding intensity for females and males of 86 ± 12.28 % and 92 ± 8 % for the Culex larvae and 91 ± 7 and 93.66 ± 5.68 for the Culiseta larvae, respectively. No significant difference was observed between the sexes or for mosquito larvae. Our data support the idea that the introduction of mosquitofish has both negative and positive effects since this fish feeds on the most abundant food and not only on mosquitoes.
