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.

Big Data Technology Architecture Proposal for Smart Agriculture for Moroccan Fish Farming

As the global population increases rapidly, so does the need for fishing products. Aquaculture is well-developed in Asian countries but is underdeveloped in countries that share Morocco's climate. To meet the rising demands for aquaculture production, it is vital to embrace new digital strategies to manage the massive amount of data generated by the aquaculture environment. By employing Big Data methodologies, aquaculture activity is handled more effectively, resulting in increased production and decreased waste. This phase enables fish farmers and academics to obtain valuable data, increasing their productivity. Although Big Data approaches provide numerous benefits, they have yet to be substantially implemented in agriculture, particularly in fish farming. Numerous research projects investigate the use of Big Data in agriculture, but only some offer light on the applicability of these technologies to fish farming. In addition, no research has yet been undertaken for the Moroccan use case. This study aims to demonstrate the significance of investing in aquaculture powered by Big Data. This study provides data on the situation of aquaculture in Morocco in order to identify areas for improvement. The paper then describes the adoption of Big Data technology to intelligent fish farming and proposes a dedicated architecture to address the feasibility of the solution. In addition, methodologies for data collecting, data processing, and analytics are highlighted. This article illuminates the possibilities of Big Data in the aquaculture business. It demonstrates the technological and functional necessity of incorporating Big Data into traditional fish farming methods. Following this, a concept for an intelligent fish farming system based on Big Data technology is presented.

Reviewing the Impacts of COVID-19 Pandemic on the Kenyan Aquaculture Sector and Future Adaptive Strategies

For many Kenyans, the aquaculture business provides a vital source of food and work. However, information on Kenya’s aquaculture sector’s resilience in the face of emerging global shocks such as the COVID-19 pandemic requires additional examination. Prior to the epidemic, Kenya’s aquaculture industry had grown from a tiny participant to a critical component of the country’s fish food system, with fish and fisheries products becoming the most extensively traded food commodity in Kenyan market places. However, as indicated in the review, the aquaculture value chain has not been scrutinised since the onset of COVID-19. Lockdowns enacted during the pandemic had a significant influence on access to aquaculture inputs, fish commerce, and the socio-economic livelihoods of stakeholders and players in Kenya’s aquaculture value chain. Thus, initial and long-term adaptive strategies, particularly those implemented by governments, could help to the development of COVID-19 specific and generic resilience to numerous shocks and stressors among stakeholders and players involved in the country’s aquaculture industry. Some of the measures include a government incentive package to help the fisheries and aquaculture sectors recover, improve farming operations, and gain market trust, as well as the adoption of new methods to reduce labor intensity, such as intelligent sensors, camera systems, and automated or remotely controlled monitoring/feeding strategies. Such strategies and policies can protect the sector from future shocks triggered by pandemics and other unforeseen circumstances.

Effective valorization of precision output of algaquaculture towards eco-sustainability and bioeconomy concomitant with biotechnological advances: An innovative concept

Both input resources and ecosystem stability are critical to the long-term viability and sustainability of the aquaculture business, which is booming while supporting global food security. Over the past few decades, technical advancements have been made to help achieve both economic and environmental goals. Among these, “algaquaculture,” which combines algae culture with aquaculture, is seen as a revolutionary concept with numerous advantages. The only difference between this system and aquaponics is that algae are used instead of leafy plants. In aquaponic systems, this integration is innovative because of algae’s superior ability to utilize waste-derived nutrients, such as nitrate, nitrite, and total ammonia nitrogen (TAN). An additional benefit of algae is that they promote growth, stimulate the immune system, and even enhance the color of fish. Some algae with human health benefits and biodiesel sources have a high market price, which can be used to compensate for an integrated aquaculture-based system’s higher economic value. While aquaculture waste bioremediation can greatly improve environmental sustainability, it is important to note that algae can play a significant part in bioremediation because of their ability to minimize environmental disruptions. This review aims to highlight the new concept of algaquaculture, functional role of algae in aquaculture, and biotechnological advancements for the bioeconomy to establish microalgae-based food production systems, including aquaculture, by citing the role and benefits of such an integrated algal-aquaculture system. For this reason, the review intends to disseminate an idea like this over the globe, focusing on how to preserve the sector in the coming years. • Algaquaculture, which combines algae culture with aquaculture, is seen as a revolutionary concept with numerous advantages. • Algaquaculture has great impact on circular and bioeconomy. • The biotechnological advances makes algaquaculture a sustainable strategy for frontiers industrial applications.

Potential of Single Cell Protein Production Using Waste as Growth Medium

Feed is an important factor affecting the growth of cultured fish. Around 86.5% of the production cost of aquaculture is allocated for the purchase of feed. Good quality and efficient feed is a determinant of the success of aquaculture business. Single Cell Protein (SCP) is a dry cell product of single cell microorganisms. SCP production is generally not only protein but also free amino acids, lipids, carbohydrates, vitamins and minerals. The purpose of this study was to analyze the growth media of Bacillus Cereus which will be used as a source of SCP by using some easy-to-use waste. The research method used is an experimental method using 2 isolates of Bacillus cereus bacteria, namely B. cereus strain SN7 and a consortium of bacterial isolates. Both isolates were grown in tofu liquid waste media, sago liquid waste media, and molasses waste media as a carbon source added with egg white as a nitrogen source with 3 replications in each treatment. The results showed that the most optimal growth medium for B. cereus strain SN7 and the consortium was molasses waste modified media which was incubated for 24 hours, compared to modified media for sago waste and tofu waste. For comparison, the isolates of B. cereus and consortium still had a higher growth potential than the isolates of strain SN7 which had been incubated for 24 hours.

Restocking of small water bodies for a post Covid recovery and growth of fisheries and aquaculture production: Socioeconomic implications

Restocking of fish in Small Water Bodies (SWBs) is one of the technologies that can be used to enhance fish-food production for post Covid recovery and growth in food security, and national development. The current study aimed at assessing the socioeconomic impact and stock performance of restocked Nile tilapia fingerlings in SWBs in 15 counties in the Western and Central regions where the Aquaculture Business Development Programme (ABDP) is implemented. The study employed both primary and secondary data from socioeconomics, environmental characteristics and fisheries and aquaculture aspects. There was no restocked dam with a low (<1.66) socioeconomic impact, indicating the potential for restocking. The majority (n = 27; 79%) of the restocked SWBs had a moderate (1.66–2.33) impact, owing to the inherent constraints of adoptability by the local community. Twenty one percent (n = 7; 21%) of the SWBs had a high (2.34–3.00) impact and with better environmental conditions. The average condition factor (K) of tilapia in restocked SWBs was 1.24 ± 0.53 SD, suggesting excellent fish growth condition. Notably, restocking the SWBs could benefit riparian fishing communities by improving their livelihoods and providing food and nutritional security. Given the limited exploitation of fish in most SWBs in the developing countries, additional community awareness and capacity building interventions are needed to enhance optimal use of SWBs in post Covid era.

Estimasi Daya Dukung Perairan Pesisir Kabupaten Pamekasan dalam Menerima Limbah Budidaya Udang Vannamei

Vannamei shrimp cultivation business is an aquaculture business that has increased every year, both from the amount of production and the cultivation technology used. Vannamei shrimp cultivation in Madura is one type of work that develops by utilizing unproductive land and salt ponds being converted into vannamei shrimp ponds. Pamekasan Regency is one of the regencies that carry out the development of vannamei shrimp farming business with an intensive system. The development of vannamei shrimp cultivation is not in line with the conditions of the aquatic environment, this is because aquaculture activities produce waste in which aquaculture waste is directly discharged into the waters. The research was carried out on February 1, 2022 to April 1, 2022 in Candi Village, Galis District, Pamekasan Regency. Based on the results of the study, it was found that the load of organic waste in the form of TSS that was discharged into the waters during one maintenance cycle was 137.25 kg and 143.38 kg/0.3 ha when pouring the entire volume of pond water (3000 m3) into the waters. Based on the carrying capacity of coastal waters, the maximum amount of waste in the form of TSS that can be accommodated by the coastal waters of Pamekasan Regency is 441.39 tons/day. The amount of waste generated from intensive system vannmei shrimp farming activities in Pamekasan Regency is 55,983.26 tons for one year and 153.38 tons/day. The results showed that the waste produced was still below the maximum waste that could be accommodated by the waters of Pamekasaan Regency.

Energy Efficiency for Florida Aquaculture Facilities: Variable Frequency Drives

Energy consumption is often a primary contributor to the cost of operation in aquaculture. Even on a moderately sized farm, excessive energy consumption can be a limiting factor in the success of an aquaculture business. Reducing operational costs can increase total profitability. Identifying inefficient energy use and implementing energy-efficient technologies can help reduce the total cost of operation. This publication is one in a series that details techniques and methods for reducing energy consumption to decrease operational costs on aquaculture facilities. In many aquaculture practices, especially finfish culture, water must be moved from one location to another. Pumping water often accounts for a significant portion of a facility’s energy use and operational costs. This publication discusses how variable frequency drives can be used to reduce energy consumption of pumps.

Effect of chromium supplementation, both organic and inorganic, on the growth capacity and genotoxicity of Labeo rohita

A control group, three groups treated with chromium chloride hexahydrate, and three groups supplemented with Cr-Pic were generated from labeorohita fingerlings. Results from the experimental group T4 that had been given 0.3 mg/kg of (Cr-Pic) and carbohydrates showed significance (P 0.05). In comparison to the control and other experimental groups, Labeo rohita showed superior growth. The aquaculture business has a minimal growth tendency, and the goal of fish feed formulation is to give fish a workable diet to improve their bodies. The biological machinery of fish relies heavily on organic and inorganic chromium compounds added to carbohydrates as an energy source. This article describes the impact of chromium picolinate (organic) and chromium chloride hexahydrate (inorganic) on Labeorohita's ability to grow and its genotoxicity. Seven groups (each with a replica) were used, with 30 each being watched in groups T5, T6, and T7. The results of the comet assay showed that fish erythrocytes had genetic damage according to dosage and Cr (organic or inorganic). So, by 0.31 mg/kg concentration, the greatest comet metrics (Tail length, Tail DNA, and Olive Tail Moment) were detected. This study suggested that organic Cr may be employed as a growth stimulator if inorganic Cr was hazardous. Overall findings suggested that organic chromium supplementation of 0.31 mg/kg should be reevaluated for growth. The goal of this research initiative is to encourage fish producers to use organic Cr-added feed because it increases yield while improving growth performance and has positive health impacts for customers that lower the danger of toxicity.

IoT-Based Real-Time Aquaculture Health Monitoring System

Aquaculture fastest growing business worldwide especially in developing countries. Fisheries are marine species and required an oceanic environment where fisheries could grow and live naturally. Off-shore aquaculture businesses need a real-time water quality monitoring system. So, aquafarmers could maintain the required environment for a sustainable and profitable business. This work represents an IoT-based realtime health management system designed for aquaculture and considered the most required health metrics for aquaculture. The proposed system used four primary sensors: water level, temperature, pH, and dissolved oxygen. Sensors connected with microcontroller Arduino Uno R3 and ESP 8266 wi-fi module are used for data transmission to the IoT source ThingSpeak. The designed system could access online through the web interface and phone App for aquafarmers. The sensor data was accurate, and the system worked as designed.

Sustainable IoT Solution for Freshwater Aquaculture Management

In recent years, we have seen the impact of global warming on changing weather patterns. The changing weather patterns have shown a significant effect on the annual rainfall. Due to the lack of annual rainfall, developing countries like India have seen a substantial loss in annual crop production. Indian economy largely depends on agro products. To compensate for the economic loss, the Indian government encouraged the farmers to do integrated aquaculture-based farming. Despite government subsidies and training programs, most farmers find it difficult to succeed in aquaculture-based farming. Aquaculture farming needs skills to maintain and monitor underwater environments. The lack of skills for monitoring and maintenance makes the aquaculture business more difficult for farmers. To simplify the pearl farming aquaculture, we have proposed an Internet of Things (IoT)-based intelligent monitoring and maintenance system. The proposed system monitors the water quality and maintains an adequate underwater environment for better production. To maintain an aquaculture environment, we have forecasted the change in water parameters using an ensemble learning method based on random forests (RF). The performance of the RF model compared with the linear regression (LR), support vector regression (SVR), and gradient boosting machine (GBM). The obtained results show that the RF model outperformed the forecast of the DO with 1.428 mean absolute error (MAE) and pH with 0.141 MAE.
