Abstract

Organic carbon source and C/N ratio play an important role in aquaculture system with biofloc technology application. Nitrogen control by adding carbohydrates to the water to stimulate heterotrophic bacterial growth by converting nitrogen into bacterial biomass. The study investigated the effect molasses, tapioca, tapioca by product and rice bran as carbon sources in a biofloc media at three different C/N ratios i.e. 10, 15, and 20 on total ammonia reduction in biofloc media. Five liters of biofloc media in a conical tank was prepared for each replicate, which consisted of 500 mL of biofloc suspension collected from a shrimp culture unit with biofloc technology application and 4.5 L seawater. Pacific white shrimp culture was performed in 40L glass aquaria at a shrimp density of 30/aquarium. There was a significant interaction between carbon source and the C/N ratio applied (P<0.05). The use of molasses resulted in the highest reduction rate irrespective to the C/N ratio. Keywords: molasses, tapioca, tapioca by product, rice bran, biofloc, total ammonia nitrogen

Abstract

This study aimed to evaluate the vibriocidal potency of Moringa leaf ethanol extract (MLEE) and assess the effectiveness of dietary supplementation of MLEE on Pacific white shrimp growth performance. A vibriocidal activity was performed using disk diffusion and tube dilution methods. The results showed Vibrio parahaemolyticus was more susceptible than Vibrio harveyii with an inhibitory zone of 11.30 to 22.90 mm. The minimum inhibitory concentration (MIC) of MLEE against V. parahaemolyticus was recorded at 12.5%, similar to V. harveyii. The effectiveness of MLEE on diet was monitored by the growth of the shrimps for 40 days of culture. Shrimps with an average initial weight of 2.50±0.05 g were acclimatized in 10 days. The MLEE was administered to the shrimps at different concentrations i.e., 10%, 15%, 20%, and 25%. The control diet was prepared without MLEE supplementation. After 40 days of culture, the shrimps fed with 10% of MLEE had the best growth. This study reported that MLEE potentially become vibriocidal agents. However, the administration on shrimp had no beneficial effect on its growth performance.

Abstract

The Sumatran Barb fish (Puntigrus tetrazona) is a freshwater ornamental fish which is highly demanded in the ornamental fish export market for its attractive colour patterns. The common problem in ornamental fish farming is the excessive use of water resources, increasing operational costs. A Recirculating Aquaculture System (RAS) is preferred since it can process water repeatedly and is more environmentally friendly. Duckweed plants (Lemna minor) can be used as a natural biofilter because they absorb nutrients such as nitrogen and phosphorus and provide a habitat for beneficial bacteria. This study was conducted for 40 days, with the treatments consisting of different plant coverage areas. Duckweed plants were applied with area coverage of P0/control (without duckweed plant), P1 (20% area coverage of duckweed plants), P2 (40% area coverage of duckweed plants), and P3 (60% area coverage of duckweed plants). The bacterial abundance values obtained during the maintenance period ranged from 1.52 to 1.79 x 106 CFU mL-1 and differed significantly (P<0.05) across all treatments. The lowest TPC value was observed in the P0 treatment (1.52 x 106 CFU mL-1), and the highest in the P2 treatment (1.79 x 106 CFU mL-1). Based on the identification test, bacteria belonging to the genera Neisseria, Acinetobacter, Nitrosomonas, and Pseudomonas were identified. Water quality parameters were optimal across all treatments, namely pH between 6.0 and 6.85, dissolved oxygen (3.43-3.95 mg L-1), TAN (0.2-0.4 mg L-1), and phosphate (1.00-2.5 mg L-1). Meanwhile, temperature and nitrate exceeded the optimal limits, with values ranging from 29 to 30 °C and 72 to 210 mg L-1 across all treatments.

Abstract

The purpose of this study was to determine the effect and optimal dose of addition of Moringa oleifera leaf extract on culture media to the growth and content of carotenoids of Dunaliella salina. The research method used was experimental with Completely Randomized Design (CRD) as the experimental design. The treatments used were different doses of Moringa leaf extract, namely A (100% walne media), B (75% Media walne + 25% Moringa leaf extract), C (50% Media walne + 50% Moringa leaf extract), D ( 25% Media walne + 75% Moringa leaf extract), E (100% Moringa leaf extract) with a dose of Moringa leaf extract that is 28 ml (100%) with repetitions 4 times. The results showed that the addition of Moringa oleifera leaf extract had a significantly different effect (P <0.05) on growth. Based on the density of Dunaliella salina showed the best treatment, namely at treatment B (75% walne + 25% Moringa extract). The best specific growth rate is found in treatment B (75% walne + 25% Moringa extract). The carotenoid content after treatment was not significantly different (P> 0.05) so that the carotenoid content in the control (treatment A) had the highest level of 1.39 µg / ml and the lowest was in treatment C of 0.19 µg / ml.

Abstract

Pacific white shrimp (Litopenaeus vannamei) is one of the leading fisheries commodities that have important economic value and are in great demand by consumers in the market. Pacific white shrimp has several advantages, namely rapid growth, able to adapt to a high range of salinity, and can be cultured with a super intensive system, but in recent years the total shrimp production in Indonesia has decreased. In 2012 the total shrimp production decreased from 1.900 tons to 1.025 tons, the virus is thought to be a pathogen that triggers disease in shrimp and causes high mortality. The type of virus that causes disease in pacific white shrimp cultivation is Taura Syndrome Virus (TSV), Infectious Myonecrosis Virus (IMNV), and White Spot Syndrome Virus (WSSV). The purpose of this study is to detect viruses that infected and determine the prevalence of viruses that attack pacific white shrimp. The research was conducted in December 2018 to January 2019 at Fish Quarantine Center, Quality Control and Security of Fishery Product Surabaya I. The material used in the study was 37 post larval samples. Samples extracted using Silica Extraction Kit, then detected molecularly using PCR (Polymerase Chain Reaction). This research was observational, then the data obtained were analyzed descriptively. The results showed that there were 3 positive samples of IMNV and 2 positive samples of WSSV with prevalence values of 8.10% and 5.40%. High and low prevalence values are influenced by the level of virus spread and inappropriate environmental conditions.   Keywords : Pacific white shrimp, PCR (Polymerase Chain Reaction), prevalence, virus.
