Do China's ecological civilization advance demonstration zones inhibit fisheries' carbon emission intensity? A quasi-natural experiment using double machine learning and spatial difference-in-differences

China's National Ecological Civilization Demonstration Zone (NECDZ) policy has a significant role in ensuring national ecological security, and it is essential to investigate how the NECDZ policy affects the carbon emissions intensity of fisheries (CEIF) to advance China's commitment to reducing carbon emissions. This study evaluates the CEIF in 30 Chinese provinces from 2007 to 2021 using ecological civilization demonstration areas as a quasi-natural experiment and double machine learning (DML)to examine the impact and internal mechanisms of NECDZ implementation on the CEIF. We also explore spatial spillover effects using a spatial difference-in-differences approach. The results reveal that NECDZ implementation has a significantly negative impact on the CEIF and this effect continues over time. NECDZ policy potentially affects the CEIF through technology development, industrial structure improvement, and reduced energy consumption. Further investigation reveals that NECDZ implementation has spillover effects and inhibits the CEIF in surrounding regions. Therefore, it is essential to focus on developing the NECDZ policy to enhance fisheries' industrial structure, encourage low-carbon innovation in fishery technologies, and increase energy consumption efficiency. This could be supported by facilitating exchanges and cooperation with other areas, considering regional disparities, and assigning common but distinct responsibility for reducing the CEIF.

Assessment and Spatio-Temporal Evolution of Marine Fisheries’ Carbon Sink Capacity in China’s Three Marine Economic Circles

With the increasing pressure of resource decline and environmental pollution faced by the green transformation of marine fisheries, marine fishery carbon sinks are an increasingly close link to national strategic interests and economic lifelines. It is, therefore, necessary to explore paths for the enhancement and development of the carbon sink capacity of marine fisheries. Based on the economic data of marine fisheries from 2002 to 2021, this paper measures the capacity and characteristics of marine fishery carbon sinks in provincial areas, applies the kernel density estimation method to depict the dynamic evolution of the distribution of absolute differences in marine fishery carbon sinks, and at the same time, identifies the factors influencing the spatial imbalance in the development of marine fishery carbon sinks as well as the spatial spillover effects. The results show the following: (1) From the total amount, the fishery carbon sink capacity of China’s three marine economic circles has fluctuated and increased over the past 20 years, with obvious differences among different circles, and the marine fishery carbon sink capacity of the eastern, northern, and southern marine economic circles has risen sequentially. This trend corresponds to the economic disparities among the three circles, demonstrating a transition from economic to industrial driving effects. (2) From the spatial point of view, the fishery carbon sink capacity shows a trend of increasing year by year, concentrating in the circles, and overflowing between the circles. (3) The results of a partial derivative test further show that among the main influencing factors of marine fishery carbon sinks, capital, labor, and market openness have direct positive effects on marine fishery carbon sinks, and the direct effect of innovation is the strongest, and the significance of the indirect effect of the three circles is weaker compared to the direct effect and total effect. As a result, the carbon sink of China’s marine fisheries has a large room for improvement, and in order to promote the high-quality development of China’s marine fisheries, it is still necessary to accelerate the circulation of resources within the marine economic circle, accelerate the research of fishery technology, actively develop the carbon sink fishery, and enhance the specialization of aquatic product processing.

Determinants of Fisheries Trade Competitiveness: The Case of Malaysia

Fisheries constitute one of the most globalised food industries and significantly contribute to a nation’s socioeconomic development and international food security. Malaysia is a small open economy endowed with fisheries resources; however, the rapid growth of international trade has changed the patterns of fish trade dependence. It has now become a fish importer and experienced a critical fish trade deficit since 2009, implicating eroding trade competitiveness of Malaysian fisheries in the global market. The existing empirical studies on competitiveness conclude that Malaysia loses the competitive status in the international fish market, but the Trade Competitiveness Index (TCI) and its determinants have not been thoroughly explored. Hence, this present study aims to examine the short and long run effects of trade openness, the exchange rate and fishery employment on the TCI of Malaysian fisheries during 1976– 2018, using an Autoregressive Distributed Lag (ARDL) approach. The findings conclude that Malaysia has lost its trade competitiveness in terms of TCI in the global fishery market. The ARDL results show that an appreciation of the exchange rate as well as more trade openness and fishery employment enhance the TCI in the short run (i.e., a few years), but have negative effects in the long run. To ameliorate trade competitiveness, higher restrictions on fish imports are recommended, as well as more adoption of science and technology in fisheries in the long run, given the nature of the exchange rate, appreciation policies are proposed in the short run.

The Development of Agrotechnopark Model Based on Modern Villages

Agrotechnopark is an area for implementing various types of technology in agriculture, animal husbandry, fisheries, and product processing (postharvest), which has been reviewed by multiple governments and private research institutions and functions as a training ground and center for technology transfer to the broader community. Implementing the Agricultural Technology Park (TTP) uses socio-cultural, ecological, and economic approaches. A comprehensive understanding of community needs will be obtained through a socio-cultural system, which will become input for the company. At the same time, the environmental system will identify the potential basis of local resource excellence as a reference for community development activities. Furthermore, the economic approach is developing productive business units to increase people's income while paying attention to market demand. South Konawe Regency is one of the autonomous regions in Southeast Sulawesi, which is supported by its potential resources. The position of the South Konawe Regency area is very strategic, a southern cross-section of the Southeast Sulawesi peninsula that connects several Regencies/Cities in Southeast Sulawesi with prototypes of coastal and inland villages. One is Atari Jaya Village because it has a heterogeneous population composition, and most of the Javanese Transmigration community is reasonably competent in agricultural development. Because of this, socio-culturally and economically, this village grows and develops and is dynamic by carrying out the diffusion of technology in various fields supporting Agrotechnopark, such as the development of Integrated Farming (Multiple cropping) and integrated farming (Mixed culture) of plantation crops and plantations. Atari Jaya Village is also a central area for the development of Agropolitan both food crops, as well as plantation and horticultural crops on a national scale and a People's Plantation Centre worthy of being an Agricultural Technology Park Area (Agro et al.) in South Konawe Regency, Southeast Sulawesi Province. Development of the Agricultural Technology Park Area (TTP) to become a center for Agribusiness and Agro-fruit tourism as a basic framework for community and regional economic growth towards Konsel Hebat Regency. Atari Jaya Village was realized as an independent village, a pilot Agrotechnopark village in South Konawe Regency, and a service center for upstream and downstream Agribusiness trade in Agrofruit and plantations.

How to improve fishery eco-efficiency by building marine ranch in China

Secondly, China’s marine ranch construction promotes fisheries eco-efficiency by improving the input efficiency of labor, fish species, fishing vessel, fishery technology extension, aquaculture area and by reducing pollutant outputs. Thirdly, the fishery eco-efficiency of the marine ranch construction region has increased annually since 2015, and technological changes, scale efficiency changes and technical efficiency changes can all contribute to the fishery eco-efficiency improvement, and increase in order. Based on the results of the empirical analyses, this paper proposes policy recommendations to improve the fishery eco-efficiency in the conjunction with the construction of marine ranch in China.

Economic Approach for Synthesis of Gold Nanoparticle-based Freeze Indicator for Fish Products

This study was conducted during the period September 2020–January 2023 at ICAR-Central Institute of Fisheries Technology, Cochin. The study was to develop a cost-effective freeze indicator using gold nanoparticles. Gold nanoparticles (AuNPs) were synthesized using chitosan and trisodium citrate (TSC) as a reducing agent. Various chitosan samples with different molecular weights were obtained from commercial chitosan units. Chitosan was employed at two distinct concentrations. The UV-Vis spectra exhibited the characteristic peak of AuNPs at 520–530 nm in all analyzed samples. The samples containing chitosan displayed a light pink color, whereas those containing TSC exhibited a ruby red color. An increase in chitosan concentration led to an increase in absorbance of the SPR peak. The full width at half maximum (FWHM), zeta potential, and conductivity of the nanoparticles were also investigated. The stability of the synthesized nanoparticles was assessed during frozen storage at -18°C, revealing that the sample containing TSC became colorless upon freezing. The stability of chitosan-containing samples improved with higher concentrations and molecular weights. No distinct color change upon freezing was observed in the samples synthesized using chitosan. The AuNPs synthesized using TSC were evaluated and the significant color change demonstrated by the sample confirmed that the nanoparticle solution synthesized using TSC at a gold concentration of 1 mM can serve as an effective freeze indicator for food and pharmaceutical applications.

Dynamic relationship between marine fisheries economic development, environmental protection and fisheries technological Progress—A case of coastal provinces in China

With the deepening of economic globalization and regional economic integration, as well as the emergence of “black swan” events such as the novel coronavirus epidemic and the Russia-Ukraine conflict, marine fisheries is increasingly linked to national strategic interests and economic lifeblood. Under the new situation, it is necessary to explore the synergistic evolution of marine fisheries economic development, environmental protection and fisheries technological progress, so as to help the sustainable and healthy development of marine fisheries. Based on the panel data of 11 coastal provinces and cities in China, from 2006 to 2020, this study constructs an integrated framework of a marine fisheries economy–environment–technology system and utilizes methods such as entropy method, Tapio decoupling index, coupling coordination degree model, and panel vector autoregressive model to analyze its comprehensive development, collaborative evolution, and dynamic correlation mechanism. Results show the following: (1) The comprehensive development index of the fisheries economy and technology subsystems was generally on the rise, but that of the marine environment subsystem was on the decline and fluctuating. (2) The development of the marine fisheries economy–technology subsystem was relatively coordinated, but the decoupling of marine environment from fisheries economy and technology was relatively obvious. The three marine fisheries subsystems reached reluctant coordination, but most of the regions shifted from being driven by economy–environment coupling to leading by economy–technology coupling, which indicates that the deteriorating marine environment hindered the marine fisheries system from achieving high-level coordinated symbiosis. (3) The three marine fisheries subsystems possessed self-reinforcing mechanisms, but the positive effect was relatively limited in long-term development. Moreover, the marine fisheries environment subsystem has yet to achieve sustainable and benign interaction with the economy and technology subsystems. Therefore, it is urgent to take quality and efficiency improvement as the core, facilitating the leap of marine fisheries economy, adopt green environmental protection as the key, consolidating the bearing foundation of marine environment, and employ scientific innovation as the sail, effectively playing the leading role of fisheries technology.

Both visible and invisible: women, risk-taking and the expansion of fisheries technologies in South India

Technological innovations in fisheries have generally been seen to exclude women, exacerbating both their economic marginalization and lack of political voice. Such a view however ignores the complexities underpinning the interface between technologies and social relationships, in particular, those of gender. In this article, we explore the impact of ring seine expansion in Cuddalore, a costal district of Tamil Nadu on the east coast of southern India, through the experiences of women fish auctioneers. We argue that women’s contributions to the fisheries sector as auctioneers serves to both sustain and finance the expansion of the ring seine technology and does not just play a supportive, buffering role for household survival. The profitability of auctioneer work has transformed these women into the primary household providers, responsible for securing the intergenerational wellbeing of their extended families. Yet, women are not a homogenous group, hence exploring why some women are able to access these opportunities successfully, negotiating both their entry into the market and financing of their roles, while others are excluded, illuminates how women navigate gendered constraints in relation to technological changes in the sector. We conclude by reflecting on the impact of the recent ring seine ban on the perceived wellbeing and growing indebtedness of these women.

A comparative study on the measurement of sustainable development of marine fisheries in China

Since 1989, China has been the largest aquatic producer in the world. The marine ecological environment is the “price” for the rapid development of fisheries economy, therefore, the sustainable development of fisheries industry is of great concern at home and abroad. This paper carried out a scientific evaluation of typical coastal provinces and cities by constructing an evaluation indicator system and clarifies the regional differences in the sustainable development capacity of China's marine fisheries industry for the first time. The results showed that since the second decade of the 21st century, the sustainability of marine fishery industry has been rising with fluctuation, among which, Shandong Province and Fujian Province have obvious advantages in sustainable development, while Tianjin, Hebei Province, and Shanghai still have large room for improvement. Resource environment and scientific and technological management factors have a significant impact on the sustainable development of China's marine fisheries, while economic and social factors have relatively little influence. Suggestions are put forward to improve the sustainable development level of marine fisheries in China's coastal areas, such as biological resources protection, fishery technology promotion and fishery industrial structure optimization.

Organoleptic and Biochemical Analysis of Traditional and Customized Product of Shidhils

A detailed survey was conducted to collect information on the present status of traditional preparation procedure of Shidhil at the Northern region of Bangladesh. A total of 10 samples of traditionally prepared Shidhil was collected from Rangpur, Kurigram and Nilphamari districts and brought to the Department of Fisheries Technology in zipper polythene packets. Proximate composition of the traditionally prepared Shidhil showed that, percent moisture content in Rangpur samples was higher than other samples whereas the percent protein found higher in kurigram samples. Customized product of improved Shidhils were prepared in the same laboratory with kachki (Corica soborna), mola (Amblypharyngodon mola), punti (Puntius ticto) and mixture of these three species of fishes. The survey on traditional preparation procedure of Shidhil revealed that the traditional preparation procedure of Shidhil is quite similar among the districts though there were some differences in shape and weight. Variations were observed in the price of Shidhils per piece and it ranged from 10 to 40 taka/piece. No wholesaler could be found in the marketing channel of Shidhil and it is prepared mostly for home consumption. The biochemical study of the improved Shidhils showed that the percent mean value of moisture, protein lipid and ash of dried fishes obtained at the initial stage changed while Shidhil was prepared using these dry fishes. In the case of kachki fish percent moisture content increased from were 16.12 to 23.84. The percent mean value of protein of dried punti fish were 51.48 which decreased to 41.07% after preparing Shidhil. On the other hand, the percent lipid value was 15.08 for dried mola which increased to 24.25 in mola Shidhil. In the case of mixture of three species of these fishes the percent mean value of ash was 12.73 which decreased 10.38 after preparing Shidhil.

Evaluation of the Physicochemical and Techno-functional Properties of Gelatin Extracted from Fish Processing Waste

The current research was completed at the Indian Council of Agricultural Research - Central Institute of Fisheries Technology (ICAR-CIFT), Cochin, Kerala, India from August 2021 to August 2022 as a modified thermal extraction protocol for deriving gelatin from processing waste of skipjack tuna (Katsuwonus pelamis) skin. The study evaluated the effect of chemical composition and molecular weight contributing to the techno-functional attributes of the resulting gelatin. In the present study, we followed warm water-coupled NaCl pre-treatment to reduce the lipid content of the extracted gelatin. The extracted gelatin was characterized for Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The amount of gelatin extracted from the fish skin was 9.30±0.22%. The protein pattern of extracted gelatin on SDS-PAGE was identical to commercial grade gelatin, which implies the purity of extracted gelatin is comparable to that of commercial one. The physicochemical and functional properties were evaluated and pose remarkable techno-functional properties. Therefore, fish processing skin waste of skipjack tuna could be effectively exploited for the preparation of commercial gelatin. The extraction protocol remains environment friendly and this approach remains optimal for food technological applications. The effective exploration contributed to nutritional benefits, technological, functional, and biological functionalities for a large fraction of applications in the area of food technology, nutraceuticals, pharmaceutics, and numerous others as a future line of research.

Utilization of Indigenous Microorganisms (IMO) on Lactic Acid Content, pH Value, Dry Matter, and Fleigh Value of Anaerobic Fermentation Cassava Skin (Manihot esculenta)

The purpose of this study was to determine the effect of using Indigenous Microorganisms( IMO) based on soybean cooking water, rice washing water, tofu dregs water, rumen contents liquid, and coconut water as a commercial starter to replace EM4 in the manufacture of fermentation based on the value of lactic acid content, the value of pH, dry matter content, and Fleigh value. This research was conducted at the Laboratory of Animal Husbandry and Fisheries Technology, Faculty of Agriculture, Tidar University. The research method used a completely randomized design with four treatments (P0 = Cassava peel + EM4 (1%) + molasses (3%), (P1 = Cassava peel + IMO 1 (1%) + molasses (3%), (P2 = Cassava peel + IMO 2 (1%) + molasses (3%), (P3 = Cassava peel + IMO 3 (1%) + molasses (3%) and five replications. The data obtained were analyzed using ANOVA and Dunnet's test, using the IBM SPSS 21 tool. The results of this study showed that the use of MOL had a significant effect (P<0.05) on pH but had no significant effect (P>0.05) on lactic acid , dry matter content, and Fleigh value. The conclusion of this study is that the use of MOL can be used as a substitute for a commercial starter because the anaerobic fermentation of cassava peels produced is included in the very good category based on the pH value, lactic acid content, dry matter and the resulting Fleigh value.

Evaluation and Determinants of the Digital Inclusive Financial Support Efficiency for Marine Carbon Sink Fisheries: Evidence from China.

The development of digital inclusive finance has greatly improved the feasibility of financial inclusion. Therefore, in the context of the constrained financing of marine carbon sink fisheries, we try to investigate whether digital inclusive finance exhibits a supportive effect on marine carbon sink fisheries and thus enhances the capacity of marine carbon sinks. Specifically, this paper empirically calculates the grey correlation between the development of digital inclusive finance and marine carbon sinks based on data in nine coastal provinces of China from 2011 to 2019. The empirical results show that the grey relational coefficients between the above two in China are more than 0.5, revealing a significant positive correlation. Then, on this basis, we estimate the digital inclusive financial support efficiency (DIFSE) for marine carbon sink fisheries by applying the Super-EBM model. In addition, the determinants affecting the DIFSE for marine carbon sink fisheries selected based on the grounded theory are explored through the Tobit model. The conclusions are as follows. First, there are time-varying characteristics and regional heterogeneity in DIFSE. Generally, the effect of China's digital inclusive financial support for marine carbon sink fisheries is expanding year by year. Among them, the DIFSE in the northern marine economic circle is currently the highest, followed by that in the south and east. Second, the input of productive factors, promotion of fishery skill, development of fishery technology, and Internet coverage will significantly increase the value of DIFSE, while output structure, income level, fishery disasters, and marine pollution will have significant negative effects on DIFSE. These empirical results can help policymakers better understand the contribution of digital inclusive finance to marine carbon sink fisheries and provide them with valuable information for the formulation of supportive policies.
