Abstract

One of the obstacles often encountered in white shrimp farming is the presence of bacterial diseases caused by Vibrio group bacteria. One of the efforts to control Vibriosis is by using antagonistic bacteria as biocontrol agents, one of which is using Pseudomonas diminuta. In this study Pseudomonas diminuta and Vibrio harveyi were co-cultured with the aim of determining the optimal density and effective incubation time of P. diminuta which could provide the highest inhibition of V. harveyi growth. This study used a completely randomized design with six treatments P0 (P. diminuta 105 CFU/ml), P1 (V. harveyi 106 CFU/ml), P2 (P. diminuta 105 CFU/ml+V. harveyi 106 CFU/ml), P3 (P. diminuta 106 CFU/ml+V. harveyi 106 CFU/ml), P4 (P. diminuta 107 CFU/ml+V. harveyi 106 CFU/ml), P5 (P. diminuta 108 CFU/ml+V. harveyi 106 CFU/ml). The results of this study showed that P2, P3, P4 and P5 had decreased growth of V. harveyi when compared to control P1 (V.harveyi 106  CFU/ml). The decrease in the growth of V. harveyi occurred at the 8th to 48th  hour. V. harveyi in P3 (2.72 × 108 CFU/ml), P2 (2.80 × 108 CFU/ml), P4 (2.96 × 108 CFU/ml) and P5 (2.90 × 108 CFU/ml) at the 48th hour of incubation was lower than P1 (3, 15×108 CFU/ml). Based on the results of the Duncan test showed that P2, P3, P4 and P5 were significantly different (p <0.05) from P1. From this study it was concluded that administration of P. diminuta at a density of 106 CFU/ml was able to reduce the growth of V. harveyi. The greatest decrease in the growth of V. harveyi occurred at the 48th hour.

Abstract

As population activity is increasing and the Kapuas river is still a means of transportation, causing Corbicula largillierti to accumulate heavy metals (Pb) and Coliform bacteria in their bodies. This makes it dangerous to be consumed by humans. Thus, this research has two main aims. First, to find out the concentration of Pb and Coliform inside Corbicula largillierti that lives at Kapuas river, Pontianak and the river’s water. Second, to analyze the health risk of consuming the clams. Furthermore, the Atomic Absorption Spectrophotometer (AAS) is used to analyze the Pb sample and the Most Probable Number (MPN) method is used to analyze the Coliform. The result of this research shows that concentration Pb and Coliform from the Kapuas river have exceeded the limits designated for aquatic biota based on the Decree of the State Minister for the Environment No. 51 of 2004. In addition, the health risk is measured using Estimated Daily Intake (EDI), Target Hazard Quotient (THQ) and Target Carcinogenic Risk (TR) with scores for each are >10 times the RfD, >1 and 10−3. This result shows that based on the clam Corbicula largillierti consumption for 70 years life span of 60 kg body weight,  had a high and negative effect on health risk problems and had a cancer risk for consumers. However, the health risk problem might increase much worse due to the long and continual period of consumption exceeding estimated daily intake.

Abstract

This study examines the function of Brachionus sp. protein on the Cluster Differentiation-4 (CD4) immune system in cantang grouper infected with VNN. The purpose of this study was to determine the protein content of Brachionus sp. which has the potential as an antivirus and to find out the benefits of Brachionus sp. on the expression of CD4 as an indicator of increased fish body defense system against VNN. Brachionus sp. itself contains three protein bands with molecular weights of 122.73 kDa, 75.49 kDa, and 13.77 kDa, which are expected to increase the immune system against VNN on cantang grouper. Protein injection of Brachionus with doses of 35 µl, 105 µl and 170 µl /150 g cantang grouper, showed that the lowest decrease was at a dose of 105 µl/150 gram cantang groupers.

Abstract

Phytogenic feed additives are plausible alternatives to antibiotics and serve as growth promoters in aquafeed. This research aims at finding the effects of varying inclusions of natural antioxidants like hibiscus (Hibiscus sabdariffa L.) and turmeric (Curcuma longa) on the growth, hematology, and nutrient utilization of Clarias gariepinus after 60 days feeding. This research used six feeds labeled as F1- F6 that varied in the composition of Curcuma longa and Hibiscus sabdariffa. The weight (g) inclusions of C. longa and H. sabdariffa were as follows, F1 0:250, F2 50:200, F3 100:15, F4 150:100, F5 200:50 and F6 250:0. Juvenile African catfish stocked at 9 catfish per 15L aquaria per 3 replicate aquariums (27/treatment feed) were fed for 60d. The catfish fed with F1 (250g H. sabdariffa) had the best specific growth rate 5.76±0.04 % day-1, lowest feed conversion ratio 1.01±0.01, weight gain 31.65±0.13 g, and protein efficiency ratio 0.96±0.07. The growth of African catfish increased with the increasing inclusion of hibiscus supplements. Hematobiochemical parameters ALT, AST was better for catfish fed high hibiscus supplements. We noticed that hibiscus inclusion was inversely proportional to cholesterol and total triglycerides levels of fish. The deposit of adipose tissues in the catfish was higher, with increasing inclusion of hibiscus than turmeric supplement.

Abstract

The purpose of this study was to evaluate the suitability of water quality parameters in intensive white shrimp (Litopenaeus vannamei) cultivation activities based on Good Aquaculture Practice (GAP) quality standards implication practice. This research was carried out with the ex-pose facto causal design concept during one cycle of shrimp cultivation, with the indicator being studied was the condition of the water quality parameters which were then corrected with the GAP standard according to the Minister of Agriculture Regulation No. 75 of 2016. The results showed that the condition of the water quality parameters during the cultivation period was still in accordance with the GAP quality standards, except for the alkalinity parameter which had a value of 157 mg/L and organic matter 104.43 mg/L, both values ​​were above the GAP quality standard threshold. The abnormal condition of the two parameters was caused by unpredictable natural and seasonal factors. This can be seen from the trend of the temperature and salinity parameter graphs that fluctuate unstable. Furthermore, for technical parameters, the cultivation system at the research site was still in accordance with the cultivation quality standards listed in the GAP. Based on the discussions, it can be concluded that the water quality parameters at the research pond location as a whole were still in accordance with the GAP quality standard which refers to the Minister of Fisheries Regulation No. 75 of 2016, except for the alkalinity and organic matter parameters which had a slightly worse concentration than the GAP quality standard.

Abstract

This experiment investigated the impact of two water sources and their quality on the survival, growth and health of Clarias gariepinus fingerlings reared in indoor concrete tanks. 400 fingerlings of mean weight 15.33±3.47 g and total length 12.63±1.00 cm (mean±standard deviation) was randomly distributed into four concrete tanks of 12 m3 capacity each. Water quality was analyzed bi-weekly throughout study duration. Growth parameters such as mean weight gain (MWG), specific growth rate (SGR) and feed conversion rate (FCR) were calculated using standard procedures. At study termination, duplicate groups per treatment were assessed for survival rate and a health status check was determined by a hematological evaluation and microscopic examination of parasitic incidence. Results indicated that fish reared in water sourced from bore-hole [BH] performed comparatively significantly better in growth (p < 0.05) than fish in water from earthen pond [EP] as the MWG stood at 294.05±79.17 g for the former against 211.03±54.62 g for the latter with the survival rates for both treatments being in excess of 90%. Additionally, fish reared in EP presented with a higher infestation load of Trichodina spp., although there was no significant difference (U = 7, p > 0.05) between fish reared in EP and BH treatments with regards to their packed cell volume levels and white blood cells. The outcome of this study shed light on the impact a water source can have on the growth and health status of C. gariepinus with a recommendation of microbiological analysis of water supply from open/surface systems before usage for the African catfish aquaculture.

Abstract

Shrimp farmers have reported mass mortality of white shrimp (Litopenaeus vannamei), reaching 2-3 kg/day in Gerongan Village, Kraton District, Pasuruan Regency in mid-2021. Preliminary analysis suggests that mass mortality was caused by bacterial diseases. Thus, to find out the main pathogen causing the mass mortality, the present study investigated microbial composition in rearing media of white shrimp (Litopenaeus vannamei) infected by the white feces disease (WFD) and healthy white shrimp using next-generation sequencing (NGS) technology. The research was conducted by collecting normal water samples and infected shrimp pond water samples. The results of the NGS assay showed that Vibrio vulnificus was found dominant in WFD-infected shrimp pond water, therefore was suspected to be the main cause of WFD.

Abstract

Tilapia fish have a salinity tolerance of 0 to 10 ppt. However, the increase in salinity causes a decrease in the growth rate of these fish. In addition, the rapid maturation of the gonads causes this fish to experience a slowdown in growth. This study aimed to know the effect of giving Melastoma malabathricum extract on the growth performance of tilapia fry reared in brackish water. The study consisted of treatment with 0, 1, 3, and 6 g/kg of feed with three replications of M. malabathricum leaf extract. M. malabathricum leaf extract was mixed in feed with a CMC concentration of 2%. Feed is given as much as 3% body weight twice a day. Observations of growth performance were carried out every seven days, and the amount of feed was readjusted based on the results of sampling fish weight. The study was conducted for 70 days using brackish water with a salinity of 8 ppt. Based on the study results, it was found that the highest growth of tilapia fry at the end of the study was found in the treatment of 1 g/kg feed. The same thing was also found in measuring feed efficiency, survival, and specific growth rate. It indicated that the best concentration of M. malabathricum leaf extract in supporting the growth performance of tilapia fry was 1 g/kg feed.
