Economic performance and marine policy implications of mud spiny lobster mariculture in Tropical Sea Cages, North-Eastern Arabian Sea, India: An empirical study in marine economics

Lobsters are one of the premium ocean resources and a highly sought-after seafood commodity globally. The increasing demand for spiny lobsters in both domestic and international markets has led to a growing interest in mariculture as a means of meeting demand. Capture-based mariculture (CBM) by the coastal communities is the only way to cater the existing demand. However, there is scant published information and continued ambiguity on the viability of spiny lobster aquaculture in the Indian subcontinent and a similar gap exists in countries engaged in lobster fattening. Thus, to bridge the gap between the viability information and CBM stakeholders, we examined the profitability and economic performance of mud spiny lobster, Panulirus polyphagus, production in open sea farming systems, specifically sea cages. Our analysis focused on economic indicators such as input costs and return value. We found that the estimated annual revenue for a single operation was USD $3605.04, with an internal rate of return (IRR) of 33% and a net present value (NPV) of USD $1226.17, demonstrating profitability. Despite this, certain bottlenecks such as limited seedstock and feed availability and cost concerns, disease management issues, regulatory complexities, market demand fluctuations limit the expansion of the industry beyond a certain threshold. This study provides useful information for enterprise building and developing better strategies for building food security and supporting traditional communities-oriented commercial lobster farming in India, and potentially in other lobster farming nations as well.

Pufferfish versus lionfish: comparing risks for Turkish marine economics

PurposeThis study aims to explore the risk level of pufferfish and lionfish by comparing them among Turkish marines. In addition, this study focuses on comparing pufferfish with lionfish to determine which one is more dangerous for marine economics in Türkiye.Design/methodology/approachThis study employs descriptive content analysis to give some qualitative evidence for the related literature. As a sample case, Türkiye was selected in the context of being a country in the Mediterranean Basin. By reviewing recent news, reports and publications, this study firstly will conclude how invasive alien marine species affect Turkish marines. Then, pufferfish and lionfish will be compared together to determine the risk level of these species for Turkish marine economics.FindingsAs a result of descriptive findings, it is seen that captured fishery has been declined in Turkey recently due to many factors including climate change, global warming, overfishing, environmental pollution and attack of invasive alien species. Pufferfish and lionfish are seen as the most spread marine species in Turkish marines. When comparing pufferfish with lionfish, it is seen that pufferfish is more dangerous than lionfish for Turkish marine economics.Research limitations/implicationsThis study provides descriptive and original findings as a result of comparison of pufferfish and lionfish due to their impact on Turkish marine economy. It is thought to give useful importation for the fight against invasive alien marine species in the Mediterranean Basin. Future studies can investigate different invasive alien marine species and their impacts on marine economics in the Mediterranean Basin.Practical implicationsBased on the Turkish cases, it is determined that there should be different policies for fight against invasive alien marine species in the Mediterranean Sea. Each marine species has different impacts on seafood market. Some of marine species can be consumed as a seafood product but some of them can't be consumed that policy makers should develop other strategies such as catching them to reduce their population in the local marines.Social implicationsThe spread of invasive alien marine species is still continuing in the Mediterranean Basin. Each country has been affected by the attack of invasive alien marine species. To keep sustainable seafood market and marine economics, countries should both implement common policies and develop policies specific to threats in their own countries.Originality/valueThis study reveals key points in the rise of invasive alien marine species in Turkish marines at first. The main contribution of this study is to be a recent sample for a country which is under attack by invasive alien marine species by giving a comparison of pufferfish and lionfish.

Research on Financial Support, Technological Improvement and Marine Economic Development for China’s Coastal Regions

Financial support (capital) and technological improvement are the crucial factors in any industry, and they are also the major factors of marine economics. However, the government has supplied a great deal of capital and the marine economy has been deeply explored and researched using advanced technology. The marine industry is still not the mainstay industry in Chinese industry. Considering this, the issues of how to address financial support, technical improvement and marine economics are common foci within the government and society, especially regarding the economic growth of China. It is necessary to develop the marine economy. However, many scholars only pay attention to the aspects of marine financial support, marine technology and marine economic development separately, and no scholars have studied the relationship between the three at present. Therefore, this article establishes a model to conduct empirical tests regarding the relationship between financial support, technological improvement and marine economic development using panel data from 11 coastal regions in China. The results show that financial support has a negative impact on technological improvement, but it has a positive impact on marine economic efficiency. Technological improvement has a positive impact on financial support and marine economic efficiency. However, marine economic efficiency has a negative impact on financial support, and it has a positive impact on technological improvement. Through impulse response analysis, there is a significant correlation between them. This article calculates marine economic efficiency with the SBM-DEA model and analyzes relationships with the BVAR model, which is proposed to improve the development and efficiency of the marine economy. Financial support should be used in the rather important parts of the marine economy so that the marine economy can achieve returns in the short-term and attract more circulating funds to enter the marine economy, which impacts the long-term stable and sustainable growth of the marine economy. Moreover, financial support, financial liberalization, technological research and technological creation in the progress of marine economic construction should focus on effectively using circulating funds, which provides geo-advantages and aids in building a new marine economic ecological circle.

A Review on Marine Economics and Management: How to Exploit the Ocean Well

With the objective of establishing methods for high-quality marine development and effective marine management, this review focuses on four dimensions of marine development: marine economy, marine resources, marine ecology, and marine accounting. The focus of marine economy research is the marine industry, with the marine circular economy being the latest research frontier. Marine resources are the foundation of the marine economy. To use different types of marine resources more efficiently, it is necessary to apply the property right system of natural resources to marine fields. The healthy development of the marine economy is guaranteed by marine ecology. How to scientifically measure marine ecological loss and evaluate the marine ecological environment carrying capacity and marine ecological security is key to the sustainable development of the marine economy. The development of the marine economy is based on successful marine accounting. The lack of marine data globally has made marine accounting controversial. The study aims to review the development history and latest research frontiers for various marine-related fields and identify existing problems in the processes of marine economic development and marine management, with a view to finding a breakthrough for transforming and upgrading marine development, improving the marine economic governance system, and strengthening the modernization of marine governance capacity, so as to better develop and utilize the oceans.

Overview of research on marine resources and economic development

Managing conflict in aquaculture

Purpose A flexible decision technology called the Graph Model for Conflict Resolution (GMCR) is applied to a generic aquaculture conflict to illustrate how GMCR can be used to systematically investigate a wide range of conflicts arising in aquaculture in order to obtain meaningful strategic insights and thereby assist in making informed decisions in aquaculture development. To emphasize the importance of being able to resolve aquaculture controversies, a review of the global economic impacts of the aquaculture industry is provided and the key stakeholders who may be involved in aquaculture disputes along with their legitimate interests are identified. The paper aims to discuss these issues. Design/methodology/approach The GMCR methodology comprises two main stages: modeling and analysis. During the modeling stage, key decision makers (DMs), the options under each DM’s control and each DM’s relative preferences over feasible states are identified based on a thorough background investigation to a given dispute. Within the analysis stage, solution concepts that describe key characteristics of human behavior under conflict are utilized to determine resolutions that could occur when DMs interact under pure competition and cooperatively. Interpretation of the equilibrium results provides meaningful strategic insights for better understanding which strategies a given DM could select as the conflict evolves over time. Findings The results demonstrate how difficult it can be to balance the interests of different key stakeholders in aquaculture development. In all possible resolutions identified in the generic aquaculture conflict, at least two DMs among First Nations, environmental group and residents (Res) would object to the expansion of aquaculture activities due to the assumption that the government would choose to appease one stakeholder at a time. They also reflect the need for a useful tool box of decision technologies for addressing the vast range of challenges that could arise in the important area of marine economics and management. Originality/value The GMCR methodology possesses several unique and key original capabilities in comparison to other conflict analysis models. First, it only requires limited information to calibrate a conflict model. Second, it contains a number of solution concepts that describe how a DM could think and behave under conflict. Third, it furnishes a range of informative output, follow-up analyses and advice for use in real-life decision support. Finally, all of the foregoing advantages of GMCR can be contained within decision support systems that permit practitioners and researchers to readily apply the GMCR methodology to real-life conflicts.

THE ROLE OF FISHERMEN IN ASSISTING MARITIME LAW ENFORCEMENT AGENCIES TO PREVENT MARITIME SECURITY THREATS

<strong>Abstrac</strong>t – Indonesia’s sea is approximately 2/3 wider than the mainland, with very strategic geographical posisition located at the cross point of Indian and Pacific Oceans. This geographical posisition serves as strategic route for shipping, with every shipment from the west to east and the opposite will sail through the Indonesian sea. This can be both opportunity or challenge, depending on how Indonesia will manage it. If the State did not manage it well, it will increase the maritime security threats, such as IUU fishing, smuggling, and piracy. These threats may seriously disrupt the marine economics development, given the limited number of armaments and personnel of marine law enforcement agencies. Therefore, the capacity of fishermen in assisting marine law enforcement agencies to prevent the maritime security threat is inevitable. This study uses descriptive qualitative method. There are two types of data sources, primary and secondary data sources. Primary sources is obtained through interview with stakeholders and fishermen organization, while secondary data source is obtained by literature study. The role of fishermen in assisting maritime law enforcement agencies, in this case PSDKP KKP and Navy, to prevent maritime security threats is prescribed role or recommended role. The prescribed role is shown by the community group program established by PSDKP and Coastal Development in Rural area which is established by the Navy. With this program, the fishermen can supply informations about maritime security threats to PSDKP and the Navy so that they can act immediately to prevent these threats.<br /><strong>Keywords</strong>: Maritime Security Threats, Fishermen, Community Group Supervisor (Pokmaswas), Development Of Coastal In Rural Area (Bindesir)

Introduction to the Special Issue: Coastal and Marginal Sea Studies

As an important part of the ocean system, the coastal and marginal sea (CMS) is a junction between land and the open ocean where the ocean-land interaction occurs, and also it is the area with substantial marineeconomic activities for many countries. The development of marine economics greatly affects the CMS environment and causes deteriorating environmental problems. The study on the CMS helps to understand how the land and ocean interact, and how the marine environment responses to the land system change resulting from economic developments in coastal regions. Therefore, deeply understanding physical properties of the CMS is of great importance not only in the earth science study, but for marine environmental protection. For past decades, a number of major interdisciplinary research projects have been conducted that were related to the CMS studies and monitoring. The Shelf Edge Exchange Processes (SEEP) experiments took place in the Middle Atlantic Bight (MAB) of the eastern U.S. continental shelf and slope. The experiments included multi-instrumented moorings and oceanographic cruises to address the problem of the fate of continental shelf particulate matter (Walsh et al., 1988; Biscaye et al., 1994). The project of the river influence on shelf ecosystem (RISE) focused on the coastal dynamics and interaction between river and coastal ambient waters supporting primary production in the Columbia River (CR) plume area. The concepts generated by the project improved understanding of the impacts of river plumes worldwide, productivity on eastern boundary systems, and the global carbon cycle (Hickey et al., 2010). The project studies suggested that river-supplied nitrate can help maintain the ecosystem during periods of delayed upwelling (Hickey et al., 2010). In addition to major researches, the observation network is an important issue in CMS studies. The U.S. Integrated Ocean Observing System (IOOS) is a vital system for integrating in-situ data and modeling simulations to provide data sources to support different kinds of applications in the CMS (http://www.ioos.noaa. gov). The system helps coastal hazard mitigation, sustainability of coastal ecosystem, fishery, and water quality, marine operation, etc. (Willis et al., 2008). Satellite imagery provides a new data source to study and monitor coastal marine environments. In the National Oceanic & Atmospheric Administration (NOAA) coastal watch program (CoastWatch, http:// coastwatch.noaa.gov), multi-satellite data of ocean color, sea surface temperature, and sea surface winds are made available to different users to enhance the coastal data accessibility (Hughes et al., 2013). Products available through CoastWatch have expanded beyond the original infrared and visible images to include synthetic aperture radar (SAR) data (Pichel and Clemente-Colon, 2000). Significant progresses in data collection technology and numerical modeling provide abundant data sources, which constitute a major driving force to advance our knowledge in the CMS and promote coastal marine environment management.

Marine economy: A proposal for its definition in the European Union

In recent years, and within the context of the EU, policies relating to the sea and oceans are being looked at from a more inclusive perspective. Although the growing socio-economic importance of the sea is increasingly evident in Europe, serious difficulties still exist when it tries to quantify marine economics, making it more difficult to adopt the strategic decisions of the governments and agents involved. These difficulties are linked both to the diversity of definitions and statistical representations of marine sectors as well as to the scant availability and quality of the data. This paper set out a specific proposal for the definition and characterisation of marine sectors and economic activities within the EU. This definition proposal is compatible with the standard statistical classifications of economic activities and European regions. In the majority of cases, it enables to compare the quantifications that can be carried out, both over time as well as between the different activity sectors, countries and regions. Furthermore, it is a concrete, practical proposal, not particularly costly to the public statistics institutes and can be applied relatively easily. ► Heterogeneous definitions of marine economy do not allow comparability. ► It is necessary to quantify the marine economy for decision makers. ► Concrete and practical proposal to quantify the marine economy in the EU. ► Definition of 9 sectors, 34 industries and 3 groups of marine activities.

Marine Economics and Policy related to Ecosystem Services: Lessons from the Mediterranean, Black and Caribbean Regional Seas

A study of trip and time charter freight rate indices: 1968–2003

This paper addresses the question of whether the time series for the trip and time charter indices between 1968–2003 and 1971–2003 are identically and independently distributed, and whether they have nonlinear dependence. The test method used was based upon the work of Brock, Dechert and Scheinkman and is called the BDS test. The results show that the indices were not random and identically and independently distributed, and indeed nonlinear dependence exists. As a consequence of this result, linear and other traditional models are not suitable for modelling the distributions; the distributions for the indices are not normal, but instead show skewness, kurtosis and non-periodic cycles, all of which we have provided estimates for. Putting the results of the present study together with previously published papers by the same authors, which have covered a range of distributions including the second-hand shipping market, the trip charter and time charter markets, it has now been demonstrated that distributions that are frequently studied in marine economics show fat tails and long-term memory. Non-normality in these distributions has been identified by other authors in previous studies also. However, previous authors have not suggested any alternative to the conventional methods of analysis and modelling. The authors of the present paper propose the use of the rescaled range analysis (Hurst exponent) which was brought into prominence by Benôit Mandelbrot. It is further proposed that future work in this field should be directed towards forecasting.
