“…The pond was in closed condition with no water exchange, and hence OM kept accumulating within the pond over time. However, sediments in this study contained a much lower OM content (12.7 ± 0.9 g kg − 1 ) than OM found in smallscale white shrimp farms (75.2 ± 38.7 g kg − 1 ) in southern Thailand [18]. In addition to the low OM content, the pH in sediments showed lower values when compared to the measured pH in water throughout the culture period.…”

“…In comparison to the L. vannamei small-scale farms in the southern region of Thailand, coastal shrimp farms used refilled water in culturing and produced 22.0 kg TKN t − 1 production [18], while sediment accumulation in this study generated~71.4 kg TKN t − 1 production or increased three-fold compared to their study. Our study showed that for the TN input, 17.0% was recovered in the 700 kg of shrimp biomass harvested from the pond.…”

In aquaculture systems, insufficient nutrients impede shrimp growth while excessive amounts of nutrient inputs lead to environmental degradation and unnecessary high investment. A study of in-out nutrient budgets in an intensive Litopenaeus vannamei farm was conducted in this work to measure the amount of nitrogen (N) and phosphorus (P) input and output from the system. The feed conversion ratio (FCR) was obtained to determine the level of nutrient input performance. Between September and December 2017, monthly water and sediment samples were taken within one crop cycle. Nutrient concentrations in sediment and water increased over 90 days. The total nitrogen concentration in the pond water and effluents were in accordance with wastewater quality control for aquaculture; however, the total phosphorus concentration failed to meet the water quality control from the water input through the end of the crop cycle. The nutrient budget model showed that the input/output contained 107.8 kg N and 178.4 kg P. Most of the N input came from shrimp diets (80%) while most of the P came from fertilizer (57%). Both N (46%) and P (54%) mainly deposited in the sediment as an output process. The FCR of this farm is 2.0. Based on the 1.8 FCR scenario, this farm could reduce 147 kg of feed in total, which accounts for 9.04 kg N and 2.21 kg P reduction. The farmer could save $1027 USD crop − 1 ($1 USD = 32.7 baht), as well as reducing uneaten food at the bottom of the pond. This study offers a simple and straightforward model that can practically reduce environmental impacts and increase the profitability of farms.

“…The application of an intensive system in aquaculture can threaten the sustainability of the adjacent environment and the business itself (Na-nakorn et al 2017). Effluents from an intensive pond are rich in organic materials and chemical compounds as a result of artificial feed usage and shrimp defecation, which can potentially pollute adjacent bodies of water (Barraza-Guardado et al 2013), increase nutrient enrichment in the water, and trigger algal blooms 4696 that are harmful to other aquatic organisms (Herbeck et al 2013).…”

Abstract. Musa M, Lusiana ED, Buwono NR, Arsad S, Mahmudi M. 2020. The effectiveness of silvofishery system in water treatment in intensive whiteleg shrimp (Litopenaeus vannamei) ponds, Probolinggo District, East Java Indonesia. Biodiversitas 21: 4695-4701. Whiteleg shrimp (Litopenaeus vannamei) is a popular aquaculture species in Indonesia due to its high market demand. It requires excellent water quality to ensure its growth rate and production. Therefore, intensive culture system is considered. However, the system threatens the sustainability of the adjacent environment and thus proper water treatment is necessary to increase the quality of water used in shrimp farming as well as the wastewater it produces. In this study, we explored the use of a silvofishery system that integrates mangroves into a pond as a potential solution to this issue. This study aimed to assess the effectiveness of the silvofishery system at treating water inputs and effluents of a whiteleg shrimp pond in Probolinggo District, East Java, Indonesia. Eight physicochemical water quality parameters and a phytoplankton community at four sampling sites during neap tide period were examined in this study. The effectiveness of the silvofishery system in increasing water quality was analyzed using analysis of variance (ANOVA), while the diversity of phytoplankton for biomonitoring was measured with the Shannon-Wiener diversity index (H’). The results showed that the mangrove effectively increased the quality of the water supply and wastewater in the intensive whiteleg shrimp pond-especially in terms of nutrient removal-as well as the biodiversity of its phytoplankton community. Other parameters such as TOM and ammonia also decreased, though this was not statistically proven.

“…The SPS used in the experiment had a low nitrogen content of 0.05% when compared with 0.12% of SS and SPS from the southern part of Thailand. Na nakorn et al [5] reported that SPS from Surat Thani, Thailand, contained high nitrogen content in the range of 0.32-0.59%. This might have been due to the shrimp being cultivated with only pallet food and the complete cleaning of the pond in every cultivation cycle.…”

“…Approximately 6.69 million tons of SPS are annually produced from the shrimp farming cultivation process as bulky local waste. After harvesting, most small shrimp farms directly drain their SPS to the canal, which causes water pollution and various adverse effects on the aquatic ecosystem due to its high salinity [4] and high nitrogen (N) content, which is approximately 3.20-5.98 gN/kg [5]. In general, the SPS waste is not treated properly before disposal.…”

The objective of this research was to study the anaerobic co-digestion (ACD) process by using two combination types of modified tapioca starch sludge (SS) and shrimp pond sediment (SPS). The response surface method (RSM) was utilized based on the central composite design (CCD) for analysis. Optimum ACD ratios between SS:SPS ratios of 1:0 (pure SS) and 1:1 obtained from the biochemical methane potential (BMP) test were further utilized in a pilot continuous stirred tank reactor (CSTR) test. The CSTR results showed that the highest biogas yield could be achieved at 422 l/kg total volatile solids added (TVS added ) with a methane (CH 4 ) content of 46.66% using a SS:SPS ratio of 1:1. Compared with the digestion of SS alone, the biogas yield was lower at 293 l/kg TVS added . The completed digestion time of ACD of SS with SPS was 5 days, and a TVS removal of 51.31% was obtained. SPS could help adjust the appropriate ratio of volatile fatty acid to alkalinity (VFA/ALK) along with increasing the system stability. It can be concluded that the ACD system of SS and SPS is capable of converting waste into renewable energy as well as reducing the environmental effects from ineffective disposal management.
