Abstract

Applying biofloc technology in the intensive and extensive culture of Clarias gariepinus can improve water quality and be used to feed fish. Aeration systems were a critical unit supporting biofloc and water quality. This study's objective was assessment to various types of diffusers on the growth and water quality in a C. gariepinus culture. Two types of diffusers unit were prepared for the experiment, there are air tube diffuser (AT) and air stone diffuser (AS). Growth parameters, water quality, and volume of biofloc were observed within 30 days. The survival rate, weight gain, average body weight, and specific growth rate of C. gariepinus were higher in the tanks that used air tubes (98%, 485.29 %, 7.52 g, 5.89%) than in the tanks that used air stones (92 %, 385.94 %, 5.98 g, 5.23%). The volume of biofloc range from 5.40-18.80 ml/L in AT tanks and 4.60-14.00 ml/L in AS tanks. There is no significant difference (p > 0.05) in water quality parameters and FCR value. However, using the air tube diffuser showed better results with the growth performance, survival rate, and formation of biofloc.

Abstract

Shrimp aquaculture depends on stable water quality, but fluctuations often reduce growth and survival, making optimal conditions essential for sustainable Penaeus monodon culture. This study aimed to evaluate key water quality parameters in two shrimp ponds and assess their suitability against established aquaculture standards. Field measurements and laboratory analyses were conducted over ten weeks across three sampling stations in each pond. Parameters measured included pH, temperature, salinity, dissolved oxygen (DO), nitrate, nitrite, ammonia, phosphate, and water hardness. Results showed that pH ranged from 7.29–7.80, temperature from 31.40–32.00 °C, salinity from 17.30–17.88 ppt, and DO from 5.29–5.87 mg/L, all within acceptable limits (SNI 8038.1:2014). Nutrient concentrations varied, with nitrate (0–0.4 mg/L), nitrite (0–0.4 mg/L), ammonia (0.1–0.4 mg/L), and phosphate (0–0.5 mg/L), where ammonia occasionally exceeded the safe threshold of 0.1 mg/L. Water hardness ranged from 0.17–0.43 mg/L CaCO₃, below the reference limit of 100 mg/L CaCO₃. Overall, the ponds provided suitable conditions for shrimp growth, but elevated nutrient levels at certain periods indicate the need for improved feed and waste management. Maintaining balanced water quality is essential to optimizing shrimp health, enhancing productivity, and ensuring the sustainability of aquaculture practices.

Abstract

The application of probiotic bacteria in black tiger shrimp (Penaeus monodon) aquaculture constitutes a preventive strategy aimed at mitigating the risk of disease outbreaks. This study aims to compare the efficacy of Bacillus subtilis and Lactobacillus acidophilus in inhibiting Vibrio parahaemolyticus infection through both in vitro and in vivo evaluations. The research was conducted from January to March 2025 at the Fisheries Biology Laboratory, Faculty of Fisheries and Marine Science, Universitas Borneo Tarakan. This study used a Completely Randomized Design (CRD) with four treatments and three replicates each, namely Control (-) uninfected and without probiotics, Control (+) infected with V. parahaemolyticus at 104 CFU/mL without probiotics, Bs given B. subtilis at 108 CFU/mL and infected with V. parahaemolyticus at 104 CFU/mL, and La given L. acidophilus at 108 CFU/mL and infected with V. parahaemolyticus at 104 CFU/mL. Observed parameters included antibacterial inhibition, survival rate (SR), mortality pattern, mean time to death (MTD), relative percentage survival (RPS), bacterial population, clinical symptoms, and water quality. L. acidophilus demonstrated greater efficacy than B. subtilis in inhibiting V. parahaemolyticus infection in black tiger shrimp. The survival rate of shrimp treated with L. acidophilus reached 69.67%, whereas the group treated with B. subtilis exhibited a survival rate of 43.00%. Overall, the application of L. acidophilus consistently yielded superior survival outcomes compared to B. subtilis.
