Abstract

Catfish (Clarias sp.) is one of the many fishery biota that has animal protein which is much loved by Indonesian people. One way to develop environmentally friendly catfish cultivation is through the implementation of an aquaponic biofilter system. This research aims to analyze physical, chemical, and biological water quality parameters in catfish cultivation with and without aquaponics, to obtain a description of the non-specific immune system which is analyzed from the conditions of phagocytic activity of catfish cultivated with and without aquaponics. The method used is by taking samples ten times per week by taking water quality parameters as well as blood samples of catfish raised in ponds with and without aquaponics. The analysis used is the unpaired T-test. Based on the results obtained, it was concluded that all parameters showed that the aquaponic cultivation media was better compared to those without aquaponics.

Abstract

Intensive ponds often experience a decrease in water quality and cause ponds to bloom due to the fertility of the pond bottom due to the buildup of organic material originating from leftover feed, feces and the remains of dead shrimp. The aim of this research is to determine the relationship between water quality and phytoplankton abundance in intensive pond types with different densities in Bayeman Village, Probolinggo Regency. The research was carried out from January to March 2023. Samples were taken using the purposive sampling method in 6 different pond plots. Phytoplankton analysis was carried out at the Laboratory of the Sand Source Freshwater Fisheries Technical Implementation Unit and the Hydrobiology Laboratory of the Fish Resources Section of the Faculty of Fisheries and Marine Sciences. Measurement of in situ water quality parameters, namely temperature, pH, brightness, DO, TDS, light intensity, salinity and ex situ nitrate, phosphate and ammonia using spectrophotometric methods. The correlation test results of physico-chemical parameters related to phytoplankton abundance have a strong and heterogeneous relationship only with the orthophosphate parameter

Abstract

This study evaluated the effectiveness of a bacterial consortium for biodegrading organic waste in vaname shrimp (Litopenaeus vannamei) farming wastewater. A completely randomized design with four treatments (1, 2, and 3 ppm, plus a control) and three replicates per treatment was used. The consortium, consisting of Lactobacillus casei, Bacillus subtilis, Bifidobacterium sp., Nitrosomonas sp., and Nitrobacter sp., was cultured in a medium containing molasses, rice bran, brown sugar, and whole milk. Over a 5-day incubation period, key parameters (TOM, BOD, ammonia, nitrite, nitrate, and bacterial viability) were measured. The 3 ppm treatment achieved the highest reductions TOM by 61.4%, BOD by 69.57%, ammonia by 68.92%, nitrite by 67.59%, and nitrate by 62.02% with bacterial viability increasing by 165% compared to the control. These results demonstrate that the optimal dose significantly enhances biodegradation under conditions of 24.3–28.9°C, pH 7.8–8.5, and DO 3.5–6.8 mg/L. In conclusion, applying the bacterial consortium at 3 ppm offers an eco-friendly and effective strategy to improve water quality in intensive shrimp aquaculture, supporting national food security and Blue Economy initiatives.
