Synthesis and characterization of gold nanoparticles using Brevibacterium casei (SOSIST-06) isolated from Southern Ocean water samples and their in vitro and in silico anti-WSSV activity

The worldwide shrimp aquaculture business, which is expanding and producing food, has experienced significant economic losses due to a variety of disease outbreaks. One of the main viral pathogens for the global shrimp aquaculture sector is the white spot syndrome virus (WSSV). There have been several attempts to eradicate the virus in shrimp, but none of them have been successful in the long-term effectiveness. In the present work, we establish the isolated strain identified as Brevibacterium casei SOSIST-06 from the Southern Ocean water sample and its capacity for green synthesis of gold nanoparticles. The nanoparticles were characterized using UV–vis spectroscopy, X-ray diffraction, and Transmission electron microscopy. The morphology of nanoparticles is most spherical and there are a few triangles with an average size ranging from 9.5 to 52.3 nm. In vitro anti-wssv activity was carried out using hybrid cell line PmLyo-Sf9 cells, and the synthesized gold nanoparticles were shown to inhibit the virus infection (attachment inhibitory and virucidal activity) with a dose-dependent effect. Further, the interaction of gold nanoparticles and VP28 envelope protein was confirmed using in silico approach. To our knowledge, this is the first study to identify that an actinobacterium, Brevibacterium casei synthesized gold nanoparticles could fight against the white spot syndrome virus. These findings do point the way towards creating potent antiviral or therapeutic techniques for aquaculture that utilize gold nanoparticles.

Sustainability level of the pearl lobster (Panulirus ornatus) aquaculture business using the systems of floating-net cage and fixed-net cage: A case study in South Sulawesi Province, Indonesia

Marine aquaculture is currently the fastest-growing seafood industry globally, offering a potential solution to overfishing problems, while enhancing food security and income generation. South Sulawesi, a province in Indonesia, is rich in aquaculture resources, one of which is lobster. The two commonly used aquaculture systems are the floating-net cage (KJA) and fixed-net cage (KJD). The growing market demand and rising lobster prices pose a threat to resource sustainability due to overexploitation. This is issue have to be addressed to achieve sustainable fishery development. Sustainability is the primary focus on global fishery development. According to the United Nations, sustainable development encompasses three dimensions: the economy, social and ecology. Therefore, sustainable fishery, particularly aquaculture, relies on obtaining significant benefits while minimizing environmental damage. Hence, this study aimed to analyze the sustainability level of the pearl lobster (Panulirus ornatus) aquaculture in South Sulawesi, based on the provided background information. The study included a sample of 62 farmers. The sample selection involved the use of the stratified sampling method, with 51 farmers from (KJA) and 11 farmers from (KJD). The sustainability analysis, conducted through assessment of based farmers’ perceptions, served as the analytical method. The findings revealed that pearl lobster (Panulirus ornatus) aquaculture has a medium level of sustainability. Employing Integrated Multi Tropic Aquaculture (IMTA) and Regional Integrated Multi Tropic Aquaculture (RIMTA) techniques is a recommended sustainability level.

What Are the Prospects of Sustainable Aquaculture in the Niger Delta, Nigeria?

Globally, the wild capture fishery is declining, and aquaculture is expanding to help fill the gap, especially in Asia and developing countries. However, the sustainability of the aquaculture sector is raising questions, and answering those questions requires the adoption of new technologies and better management practices. Nowhere is this seen more clearly than in Nigeria where aquaculture generally means catfish, the most farmed species of which is clarias garipinus because it is a native species, and it plays an important role in the average Nigerian diet. However, small-scale catfish aquaculture businesses are affected by various challenges that threaten the sustainability of the sector. Prominent among these challenges are: poor management skills; lack of good quality fish seed supply; high cost of fish feed; inconsistency in government policy and limited regulations; lack of consideration about the impacts of aquaculture practice on the environment causing water pollution and environmental degradation, and insecurity of investment against natural disasters such as floods. This research investigated these challenges in eight sites in two states (Delta and Bayelsa) in the Niger Delta region of Nigeria. Data were gathered from a survey questionnaire, key informant interviews, personal observations, and published literature. Key findings showed that the sustainable development of the small-scale catfish farming industry in Delta and Bayelsa states is vulnerable to several threats that prevent it from fulfilling its undoubted potential to grow into a much larger sector, which could significantly reduce Nigeria’s reliance on fish imports, as well as relieve pressure on the overfished marine catch sector. Nevertheless, despite the threats, most catfish farmers are committed to their work and deserve the support of the government to enable them to succeed.

Feasibility Analysis of Tilapia Fish Farming in Floating Net Cages (KJA) in Lake Ranau

Lake Ranau is located on the border of West Lampung Regency, Lampung Province and South Ogan Komering Ulu Regency, South Sumatra Province. Lake Ranau has functions including ecological and socio-economic cultural functions. Some important technical aspects in a tilapia aquaculture business in KJA include KJA components, maintenance/production processes ranging from seed stocking, feeding to harvesting and constraints faced by farmers during the production process. The criteria observed in determining the feasibility of tilapia KJA cultivation include: investment costs, profits, profitability, BEP (Break Event Point) and R / C Ratio (Revenue Cost Ratio). Economically, tilapia aquaculture in KJA in the waters of Lake Ranau is profitable and feasible for both category I and category II. The profitability value of this KJA farming business is 115% for category I and 119% for category II. The R/C ratio value in one production cycle is 2.15 for category I and 2.19 for category II which means the business is feasible to establish.

Occurrence of Cryptosporidium oocysts in commercial oysters in southern Thailand

The enteric parasite Cryptosporidium is spread through the fecal-oral pathway, most commonly by the consumption of contaminated water but also through food. Because eating raw or barely cooked shellfish might put consumers at risk for cryptosporidiosis, identifying the parasite in oysters is important for public health. A total of 240 oysters, collected from two shellfish aquaculture sites in Thailand's Gulf coast, Nakhon Si Thammarat and Surat Thani, were tested for the presence of Cryptosporidium. Escherichia coli, enterococci, and thermotolerant coliform total levels were measured to assess seawater quality in the shellfish production regions. Oocysts of Cryptosporidium spp. were detected in 13.8% of the samples processed by immunofluorescence analyses. The detection of Cryptosporidium spp. oocysts in oysters obtained from Surat Thani (17.5%) was higher than in those obtained from Nakhon Si Thammarat (9.2%). The difference in detection of positive samples obtained from Nakhon Si Thammarat and those obtained from Surat Thani may be attributed to the effects of physical, ecological, and anthropogenic conditions, resulting in an increased level of marine water contamination by Cryptosporidium spp. oocysts. These findings demonstrate that native commercial oysters obtained from Thailand's southern Gulf coast contained Cryptosporidium spp. oocysts which might serve as a source of human infection. Consequently, these findings pose a serious public health concern and suggest that more quality control measures need to be implemented by the oyster aquaculture business to ensure the safety of seafood.

The Role of Social Capital in the Development of Shrimp Cultivation Pond Business

Shrimp cultivation is a priority in the aquaculture sector, and the development of aquaculture in Indonesia to improve the national economy; something that cannot be ruled out is the element of social capital. This social capital is related to various forms of cooperation or collective action in society to achieve better life goals, which are supported by values, norms, trust, and networks. To overcome the various obstacles that arise in the implementation of the development and expansion of the shrimp pond business, group members or the community of Pedes District, Karawang Regency, cooperation and active participation from the community are needed. The component of social capital in the form of trust is the basis for forming social interaction. In addition to the trust that must exist between farmers, there is a desire to participate and form a network, both among fish farmers and with other parties such as investors and collectors or companies that accommodate their crops. So, social capital plays a role in developing shrimp farming in Karawang Regency. The data collection technique used is observation and in-depth interviews with a key informant who is an elder figure (star person) and three representatives of aquaculture farmers who have been cultivating for the last ten years so that primary data is obtained from informants regarding the role of social capital in developing aquaculture businesses. Shrimp Ponds in Pedes District, Karawang Regency.

Habitat suitability modelling for an integrated multi-trophic aquaculture (IMTA) system along Europe's Atlantic coast

As the human population grows, so too does the demand for resources. This demand has led to aquaculture becoming the fastest growing food production sector in the world. Due to environmental concerns associated with finfish aquaculture, Integrated Multi-Trophic Aquaculture (IMTA) has been proposed to minimise any negative impacts, by co-culturing extractive aquaculture species from different trophic levels to remove excess organic and inorganic nutrients, using them for their own growth. This study, in the Atlantic area of Europe, aimed to identify the most suitable locations to establish a new IMTA system for the 3 species Salmo salar (Linnaeus, 1758), Mytilus edulis (Linnaeus, 1758), and Laminaria digitata ((Hudson) JV Lamouroux, 1813). Habitat suitability models were created using spatial jackknifing testing within MaxEnt software and analysed using ArcGIS (ArcMap 10.8.1). All Maxent models were better than random when predicting species distribution, with AUC values of 0.889 (S. salar), 0.876 (M. edulis) and 0.901 (L. digitata), indicating a high level of predictive power. Jackknife testing identified Chlorophyll A (mg m−3) and Salinity (PSS) as the 2 most important variables in the model for each species. Coastal areas of the United Kingdom, Ireland and Northern France were identified as highly suitable, with suitability decreasing in more southern environments. These areas were then assessed based on local vessel density, whether they were within a Marine Protected Area (MPA), and the site accessibility from nearby ports, according to the expected needs of a large-scale aquaculture system. As MaxEnt used wild population data to produce the models, environmental conditions at suitable areas were compared against known Salmo salar aquaculture sites in Scotland to further validate the suitability for IMTA purposes. The results of this study, and the identification of optimal conditions for each species, will provide aquaculture businesses with the information required for preliminary site selection, with the goal of further incorporating IMTA systems into the EU market in a sustainable way.

Natural Spawning Technique of Koi Fish (Cyprinus carpio) in the Ciparanje Inland Fisheries Area, Sumedang, Indonesia

The Ciparanje inland aquaculture area has emerged as a hub for breeding ornamental fish, with koi fish being a prominent species. The increasing demand for koi fish has led to a surge in koi aquaculture businesses. What sets koi fish apart from some other fish species is their ability to breed throughout the year, unaffected by specific seasons. However, in their natural habitat, koi fish typically spawn at the onset of the rainy season, triggered by the enticing aroma of the soil. The growth of koi fish is influenced by various factors, including fish species, genetic characteristics, feeding efficiency, disease resistance, and environmental conditions such as water and feed quality, as well as stocking density. To ensure the production of top-quality koi fish fry, it is crucial to employ the appropriate spawning techniques. In this study, a participative approach was employed to investigate and report on the natural spawning procedures of koi fish in the Ciparanje inland aquaculture area, managed by Padjadjaran University. The natural spawning method implemented in this area encompasses several crucial processes, including the preparation of spawning ponds, selection of breeding stock, egg hatching, and larvae rearing. A total of 90,175 eggs were collected from the examined koi broodstock during the spawning activities, and an impressive 80% of these eggs successfully hatched. The calculated Hatching Rate (HR) reached 96.5%, indicating a high level of achievement in the hatching of koi fish larvae.

The utilization of rice straw (Oryza Sativa L.) as a green catalyst in the enhanced production of hydrogen via the thermochemical conversion process of shrimp farm sludge

The catalytic mechanism of rice straw, Oryza Sativa L., on the carbonation of shrimp farm sludges via the gasification process was investigated in this work. Rice straw possessed 75% of its weight is silicon dioxide (SiO2) which can be utilized as an effective catalyst whereas the tar decomposition and gas production during the thermochemical process can be enhanced. In that manner, the influence of working temperature (oC), the ratio (%wt) on the amount of rice straw used in the shrimp farm sludges, and the moisture content (%) in the prepared samples are taken into account to determine the role of rice straw catalytic. Gasification processes were carried out in 60 min in a stainless steel reactor, with a feeding rate of 0.5 kg/h and an air-pumped flow rate of 2 L/min. All experiments were performed under different conditions of working temperatures (600, 700, 800, and 900 °C), sample composition (0, 20, 40, and 60 %wt of rice straw added), and moisture content of the feedstock (20, 40, 60, 80, and 90%). It is essential to confirm that the change in sample moisture content and the working temperature are also significant to the production of hydrogen throughout the process. As the moisture content increase from 20 to 40%, the hydrogen yield is proportionally increased by 5–10%. On the aspect of working temperature influence, the hydrogen composition increased from 11% at 600 °C to 27% at 900 °C for the RS sample, from 13% at 600 °C to 29% at 900 °C for the RS20, from 17% at 600 °C to 35% at 900 °C for the RS40 sample, and from 19% at 600 °C to 43% at 900 °C for the RS60 sample. The findings in this work confirm the rice straw catalyst's role in enhancing hydrogen production via the gasification process. Furthermore, this work provides guidance information for simple but effective processes that can not only deal with the sludge waste management issue but also create a waste-to-energy route suitable for medium and small-scale aquaculture businesses.

Small-Scale Vannamei Shrimp Farm Business Sustainability Analysis With Micmac: A Study on Kebumen Coastal Area, Indonesia

Purpose: The objective of this study was to identify the internal and external factors of the sustainability of the vannamei shrimp farming business and the relationship of influence and dependence between the factors. Theoretical framework: Sustainability is required to create a balance between nature and humans for the use of coastal space in Kebumen Regency as a development area for the shrimp farming business to be carried out sustainably and provide sustainable benefits, as well as to preserve existing resources for long-term sustainability (UN, 2020). Development that ignores the interaction of the two results in price increases, which leads to a general decline in human welfare (Fauzi, 2019). This is to the global development agenda and the Sustainable Development Goals(SDGs)., which call for Indonesia to become a maritime axis. Design/methodology/approach: The research used a participatory method with semi-structured and in-depth interviews with the shrimp farming community and FGD. The data were analyzed using the sustainability analysis technique of Matrix of Cross Impact Multiplications Applied to a Classification (MICMAC). Findings: Identification of key elements in the sustainability of shrimp farming is essential to overcome and limit the risk of uncertainty caused by external and internal disturbances and pressures on shrimp farms. Government policy is a variable that has a strong and large influence on the sustainability of the shrimp farming business, and good government policy will enable the shrimp farming business system to reduce the pressure and threat of continuity. Research, Practical & Social implications: Future research should focus on the management of shrimp farming and waste management to reduce the ecological, social, and economic impacts and the sustainability of shrimp farming that is environmentally and socially friendly. Originality/value: Government policy is a variable that has a strong and significant impact on aquaculture sustainability, with good government policies allowing the aquaculture system to reduce pressure and threats to shrimp. According to the facts on the ground, the shrimp farming business on the coast of Kebumen regency is operating independently due to a lack of attention, guidance, and policies governing the implementation of the shrimp aquaculture business.

Machine Learning Integrated Multivariate Water Quality Control Framework for Prawn Harvesting from Fresh Water Ponds

Water contamination, temperature imbalance, feed, space, and cost are key issues that traditional fish farming encounters. The aquaculture business still confronts obstacles such as the development of improved monitoring systems, the early detection of outbreaks, enormous mortality, and promoting sustainability, all of which are open problems that need to be solved. The goal of this study is to provide a machine learning (ML)-based aquaculture solution that boosts prawn growth and production in ponds. The study described a proposed framework that collects data using sensors, analyses it using a machine learning framework, and provides results like a preferred list of water quality (QOW) variables that affect prawn development and yield, as well as pond categorization into low, medium, and high prawn-producing ponds. In this study, we use eight distinct machine-learning classifiers to discover the driving elements that influence the development and yield of aquatic food products in ponds in terms of QOW variables, as well as three feature selection approaches to identify the aspects that have the largest impact on the pond's total harvest performance. To validate and obtain satisfying results, the suggested system was installed and tested. The average F score and accuracy when yield is employed as a harvest parameter are determined to be 0.85 and 0.78, respectively. The average merit ratings of temperature, dissolved oxygen, and salinity are significantly higher than those of the other QOW components. The temperature variations are greatest during the second, fourth, and seventh weeks. Temperature, salinity, and dissolved oxygen are the three QOW variables that have the largest influence on overall pond harvest performance, according to the data. Additionally, it has been discovered that a key QOW factor in separating high-yielding ponds from low-yielding ponds is the temperature change following stocking.
