The purpose of this study is to reuse shrimp pond bottom sludge for industrial-scale organic fertilizer production, to reduce emissions from shrimp farming, and protect the environment. Sludge from the bottom of shrimp ponds is collected through channel settling with a filter net of 0.25 millimeters in size, rainwater is used to wash the salt content in the sludge of shrimp ponds. When the EC (Electrical Conductivity) of the sludge drops below 4 mS / cm, the sludge is mixed with dry straw at the rate of 1 ton of sludge with 250 kg of straw. The products of this rice straw and sludge mixing process are bio-fermented in two phases including anaerobic phase and aerobic phase. The results showed that the sludge-based fertilizers meet national technical regulation QCVN 01- 189: 2019/BNNPTNT. Of quality parameters, total organic carbon, macronutrients (N, P2O5, K2O), trace metals (Zn, Cu), and other heavy metals (Pb, Cd) are within the regulation limits. The paper also shows the potential of reusing shrimp pond bottom sludge for industrial-scale organic fertilizer production, with the possibility of utilizing nutrients contained in the sludge supplied to crops, especially reducing environmental pollution from intensive shrimp farming.

Abstract. Takarina ND, Utomo SW, Susanti L, Rochman NT, Cahyadi D, Junaedi H, Saputra HKH, Saputra RN. 2020. Phytoplankton biodiversity trends in nanobubble aerated shrimp farming at Probolinggo coast, East Java, Indonesia. Biodiversitas 21: 5906-5914. Phytoplankton is known as an important factor in shrimp farming and its abundance and biodiversity are varied. Nanobubble aeration is one of current aquaculture treatments used in brackish water shrimp ponds. This study aimed to investigate phytoplankton biodiversity trends in nanobubble and control ponds within 21-day observation period. The measured water quality parameters were dissolved oxygen (DO), NH4+, NO2-, pH, salinity, temperature, and water clarity. Data analysis includes calculation of abundance and biodiversity using Shannon-Wiener (H’) index and correlation using Principal Component Analysis (PCA). A total of 11 phytoplankton species from 5 divisions was recorded. The results show increasing trends in phytoplankton abundance, species, and H’. In pond with nanobubble, H’ increased from 0.322 (95%CI: 0.074-0.718) to 0.561 (95%CI: 0.208-0.916) after 21 days, while in control pond, H’ increased from 0.199 (95%CI: 0.000-0.520) to 0.326 (95%CI: 0.000-0.683). In the nanobubble pond, species showing increasing trend in abundance were Pleurosigma sp., Nitzchia sp., Anabaena sp., Oscillatoria sp., and Microcystis sp. Whereas, species showing a declining abundance trend were Chlorella sp. and Amphora sp. According to PCA, phytoplankton abundance was positively correlated with pH, water clarity, DO, NO2-, and negative correlation with salinity, temperature, and NH4+.

Brackish water ponds for farming black tiger shrimp (Penaeus monodon) have recently proliferated in inland areas of Thailand's central plain, raising concerns about land and water salinization. The environmental impacts of inland shrimp farming were assessed by analysing the salt balance for an inland shrimp farm. Field data on water fluxes and pond salinity, collected from nine ponds in Chachoengsao Province from May–July 1999, were used to model the salt balance for a typical shrimp pond over one growout cycle. During growout, seepage represented 38% (11.5 tonnes crop−1) of salt losses, pond discharge 33% (9.7 tonnes crop−1), and accumulation of salt in pond sediment 6% (1.8 tonnes crop−1). About 23% of the initial salt content remained at harvest and could have been recycled. However, the majority (84% on average) was discharged to the irrigation canals. Much of the salt in pond sediment was also exported to the canal system through tidal flushing of the ponds. Field measurements of salinity were taken in adjacent canals and rice paddies to explore the impacts of salt exports from shrimp ponds. Pond discharge caused increases in canal salinity above levels that would impact on yields of irrigated rice and orchard crops, the main land uses in the region. Elevated soil and water salinity in adjacent rice fields was probably related to lateral seepage from the ponds. The salt budget was also modelled for a zero discharge farming system, promoted by proponents of inland shrimp farming as having few impacts. However, the results suggest that, even in zero discharge ponds, almost half of the initial pond salt content is exported through seepage (45%, 12.4 tonnes crop−1), with another 6% (1.8 tonnes crop−1) deposited in sediments. While techniques exist for mitigating much of the salt leakage, the likelihood of their uptake in Thailand is low. Further expansion of inland shrimp farming in the central plain is therefore likely to contribute substantial salt load to the area's land and water resources.

Abstract. Afsholnissa S, Hernawan E, Lastini T. 2019. Land cover change and land use suitability analyses of coastal area in Bantul District, Yogyakarta, Indonesia. Biodiversitas 20: 1475-1481. Shrimp farming in the southern coast of Bantul District is considered to be the cause of environmental degradation, decline of mangrove association due to logging for land conversion to shrimp pond and also considered to be the cause of agricultural land for crops around the shrimp pond. The purpose of this study was to identify land use change and analyze the land suitability for shrimp farming, agriculture, and mangrove plant associations. Identification of land use was done using ENVI 5.3. The study identified 34.88 ha (3.16%) empty ponds, 20.97 ha (1.90%) active ponds and as much as 91.93 ha (8.31%) land used for agriculture. The identification of land use change using Google Timelapse revealed a dominant land conversion of sandy soil and mangrove plant area into shrimp ponds in 2007 and continue to increase from 2011 to 2015. Land suitability was evaluated using ArcGIS 10.5 with an overlay method. The results revealed that 634.82 ha area of the land was suitable for shrimp ponds and ​​84.32 ha area were suitable for non-paddy agriculture. Lands suitable for paddy field were about 148.58 ha, and that for mangrove plant association was 616.42 ha. Spatially, coastal area of ​​Bantul District was dominantly suitable for shrimp farming.

Shrimp Farms

Intensive shrimp farms need mangroves to increase the carrying capacity of their waters. Every 1 Ha of intensive shrimp pond requires 7.2 Ha mangrove to absorb nitrogen (N) and 21,7 Ha to absorb phosphor (P) from waste water disposal. This study was conducted to estimate the extent of lmangrove required to absorb nitrogen (N) and phosphorus (P) wastes removed from intensive shrimp farming in Banyuputih Subdistrict of Situbondo Regency. From the field survey results obtained data on the area of ​​productive intensive ponds in the District Banyuputih is 39 Ha. The result of data analysis indicate that 280,3 Ha mangrove is needed to support the absorption of nitrogen (N) and 846,3 Ha mangrove to absorb phosphorus (P) of effectiveness pond waste pond in the study area. The mangrove in this subdistrict of Banyuputih (540,18 Ha) still support in the absorption of nitrogen waste (N), but for the absorption of phosphorus posfor (P) ponds still needed reforestation of at least 304,12 Ha from the existing mangrove area. If the local government intends to develop intensive shrimp ponds in accordance with the carrying capacity or maximum capacity of coastal waters of Banyuputih in decomposing 58 ha of tambak organic ponds, the current mangrove condition (540.18 Ha) still supports the absorption of nitrogen (N) from ponds intensively covering an area of ​​58 Ha, but to absorb the posfor (P) lagoon is still needed addition (reforestation) of 718.42 Ha.

The development of new technologies in automation to increase labor productivity has been increasingly enhanced in recent decades. The problem of cleaning water in shrimp ponds greatly affects the quality as well as shrimp production. Environmental pollution of shrimp farming is a matter of concern because the current waste treatment solutions are not yet thorough. A waste remover of shrimp waste combined with the pond bottom siphon method has been researched and developed to increase the ability to thoroughly handle waste generated in the culture environment. This device helps to automate the manual cleaning of the pond bottom by farmers. The device performs operations to clean waste, suck, filter, and remove waste from the culture environment. This device is self-propelled or manually controlled and operates in all weather conditions. This article introduces the process of testing and evaluating the efficiency of waste extraction equipment in shrimp ponds. The device was tested at a super-intensive shrimp farm and evaluated for operational efficiency. The experimental model consists of a shrimp pond operating a waste suction device, a control pond, an automatic monitoring system of water quality parameters (DO, H2S, NH3, pH, and temperature). Experimental ponds operating waste disposal equipment, control ponds are manually cleaned, other farming conditions of the two ponds are similar. The impacts of waste on the shrimp culture environment are determined through analyzing the results of measuring water quality criteria in the pond, thereby assessing the efficiency of waste removal of the equipment. The measurement results show that water quality parameters reach a value within the threshold if operating a waste suction device once per day. The benefits of waste remover operate to help save the cost of labor to clean the pond bottom, protect workers' health.

Abstract Water quality, chlorophyll a, phytoplankton, proto and mezo-zooplankton abundance were spatiotemporally evaluated in an estuary receiving effluents from a Pacific white shrimp Litopenaeus vannamei farm in Patos Lagoon estuary, Southern Brazil. Samples were taken before (BD) and; 1 day (1 PD) 5 days (5 PD), 10 days (10 PD), 20 days (20 PD) and 30 days (30 PD) after the effluents discharge. Some water quality parameters were affected by the effluents discharge; however, these changes were restricted to a distance of 20 m from the effluent discharge channel for a period of 5 days. The microbial community was dominated by chlorophyceae, followed by diatoms, cyanobacteria and ciliates. There was an increase in the abundance of different groups on the 1 PD sampling compared to BD. The zooplankton abundance was low in practically all sites, except for 30 PD sampling. The meso-zooplanktonic organisms were represented by copepods, mostly Acartia tonsa. Despite some effects on water quality and phytoplankton and protozooplankton abundance until 5 PD sampling, these alterations dissipated in a short period of time. We conclude that the environment quickly assimilated the effluents discharge, and the water quality parameters remained within the limits stipulated by standard guidelines.

The Status

Antibiotic has frequently been used in the shrimp-farming process in Vietnam. This leads to the status that antibiotic-resistant bacteria and products do not receive in the market. Bacteria had the resistant ability to pathogenic bacteria in water, and they have an important role in sustainable aquaculture. This study aimed to isolate and select good bacterial strains against Vibrio parahaemolyticus, pathogenic bacteria, on shrimp from 8 samples of shrimp pond water at 3 villages Ngu Lac, Phuoc An and Long Toan of Duyen Hai district, Tra Vinh province on NB agar medium. As a result, fifty-nine bacterial isolates were isolated and 10/59 isolates (16.95%) were identified as resistant to Vibrio parahaemolyticus by the well diffusion method. In 10 isolates, there were 7 isolates had good resistance to select for PCR technique and sequencing. The result indicated that these seven strains, including DH1m, DH2f, DH4d, DH8i, DH8m, DH8n, belonged to Bacilli and DH1n strain belonged to Streptomyces sp.

Isolation And Characterization

Anoxygenic phototrophic purple bacteria are ubiquitous in aquatic and terrestrial environments and demonstrate broad phenotypic diversity. Purple bacteriaderive energy from light under anaerobic conditions via anoxygenic photosynthesis, a process in which water is not the electron donor. It has been suggested that these bacteria are useful for a variety of applications, including: wastewater treatment; heavy metal remediation; nitrogen fixation; and, control of CH4 emissions. In this study, the goal was to isolate and characterize PNSB from shrimp ponds in Thailand. Surface water and sediment were collected. Enrichment cultures were prepared using Pfenning’s mineral media. As indicated by development of reddish color and turbidity, anoxygenic phototrophic growth was observed within two days of incubation. Cultures in liquid media and on solid plates exhibited a deep red or purple color ten weeks post-inoculation. Under light microscopy, enrichments consist of communities dominated by thin, elongated gram-negative cells with granules of elemental sulfur, which are characteristic of purple bacteria. Molecular methods confirm the presence of pufLM, a genetic biomarker for purple bacteria (e.g., Thiohalocapsa marina, Allochromatium vinosum, Roseovarius tolerans). Initial sequencing of key genes (i.e., pufLM) indicate that these environmental samples contain novel isolates or “geographic variants” that have not been previously described. We have developed a few pure cultures of multiple species from these environmental samples. Since shrimp farming is a key industry in southern Thailand, the characterization of the microbial communities in these ecosystems, including anoxygenic phototrophs, will provide insights into how to maintain water quality in these food production systems.
