Abstract
The COVID-19 pandemic exposed the fragility of global and domestic seafood markets. We examined the main impacts and responses of the small-scale fisheries (SSF) sector, and found that mitigation and preparedness strategies should be prioritised to boost resilience in SSF. We provide five policy options and considerations: (1) improving access to insurance and financial services; (2) strengthening local and regional markets and supporting infrastructure; (3) recognising fisheries as an essential service; (4) integrating disaster risk management into fisheries management systems; and (5) investing in Indigenous and locally-led fisheries management. Response and recovery measures need to explicitly build strategies to maintain or boost inclusion and equity in SSF.

A critical review of current progress, challenges, and future prospects. Int J Biol Macromol 2024; 276:133971. [PMID: 39032890 DOI: 10.1016/j.ijbiomac.2024.133971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 05/28/2024] [Accepted: 07/16/2024] [Indexed: 07/23/2024]
Abstract
Exploration of Pleurotus ostreatus as a biological agent in the degradation of persistent plastics like polyethylene, polystyrene, polyvinyl chloride, and polyethylene terephthalate, revealing a promising avenue toward mitigating the environmental impacts of plastic pollution. Leveraging the intrinsic enzymatic capabilities of this fungus, mainly its production of laccase, presents a sustainable and eco-friendly approach to breaking down complex polymer chains into less harmful constituents. This review focused on enhancements in the strain's efficiency through genetic engineering, optimized culture conditions, and enzyme immobilization to underscore the potential for scalability and practical application of this bioremediation process. The utilization of laccase from P. ostreatus in plastic waste management demonstrates a vital step forward in pursuing sustainable environmental solutions. By using the potential of fungal bioremediation, researchers can move closer to a future in which the adverse effects of plastic pollution are significantly mitigated, benefiting the health of our planet and future generations.

Ecosystem-based fishery enhancement through pen culture of Indian major carp Labeo catla in a tropical floodplain wetland of North Eastern Region, India, during COVID pandemic. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024; 31:10533-10544. [PMID: 38198088 DOI: 10.1007/s11356-023-31740-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/22/2023] [Indexed: 01/11/2024]
Abstract
The present study was conducted with the objective of developing ecologically and economically feasible pen culture protocols for Labeo catla as an alternate income source for wetland fishers in the context of the COVID-19 pandemic. Yearlings of L. catla (12.33 ± 1.99 cm mean total length and 26.05 ± 6.57 g mean weight) were reared in HDPE pens (500 m2 area each) at three different stocking densities of 3 (SD3), 6 (SD6) and 9 (SD9) no. m-2 in triplicates. Fishes were fed with floating pelleted feed containing 28% crude protein and 5% crude lipid two times daily at 1.5-3% of body weight. During the culture period, fish grew from 26.05 ± 6.57 to 434.61 ± 30.63 g, 306.13 ± 10.68 g and 221.13 ± 14.92 g, respectively, at stocking densities of 3, 6 and 9 no. m-2 respectively. Weight gain percentage and specific growth rate declined with increase in stocking density. Gross fish yield increased with increase in stocking density and was highest at SD9 (657.92 ± 53.55 kg pen-1), while net fish yield increased initially from SD3 to SD6 (594.31 ± 29.72 kg pen-1) and then declined with further increase in stocking density. Important water quality parameters influencing fish growth were measured, and significant difference (p > 0.05) was not observed between treatments (inside pens) and reference site (outside pen at 10-m distance). Weight gain was positively correlated (p < 0.05) to water temperature (r = 0.989) and total phosphorus (r = 0.81). Benefit cost ratio and net return was highest at SD3 (1.61; US $518.88, respectively). Stocking density of 3 no. m-2 can be considered economically feasible for table fish production of L. catla in pens. Post pen culture, monthly income of fishers increased by 10.76-179.11%, with a mean increase of 90.57%, compared to the period of first COVID-19 wave in India. The present findings can provide an impetus for effective utilization of pen enclosures for income generation and livelihood enhancement of small-scale wetland fishers during pandemic.

Abstract
BACKGROUND COVID-19 pandemic resulted in widespread and devastating physical, emotional, societal, and economic repercussions among workers in India. OBJECTIVES To evaluate the impact of COVID-19 and to understand the challenges faced and coping mechanism adopted among fishermen community from the coastal area of Karnataka. METHODOLOGY This community-based mixed-methods study included participants from a coastal Karnataka fishermen's community. Questionnaire based personal interviews collected information on sociodemographics, COVID-19 diagnosis, treatment, and related costs, COVID-19-appropriate behavior and were screened using DASS-21. Focus group discussions and key informant interviews were conducted to acquire qualitative data. RESULTS Quantitative data collection involved 107 participants, predominantly males [70.1%], aged between 46-60 years [37.4%] and low socioeconomic status [79.4%]. Among 107, 51 participants reported to have probable COVID-19 symptoms. Around 11% had tested for COVID-19 and two were admitted in hospital with mean hospital stay of seven days. According to DASS-21, 20.6%, 15.9% and 9.3% of participants screened positive for depression, anxiety and stress respectively. Nearly one third of the participants were found to have significant socioeconomic impact. Major challenges faced included loss of livelihood, inaccessibility to health care, repayment of loans, stigma related to COVID-19 and meeting educational expenses of children with one dropping out of college. Activities of local self-help groups in the community and grass root level marketing strategies to sell fish were highly successful in mitigating the impact as a community. CONCLUSION COVID-19 had a significant impact on fishermen community and implies a need for better pandemic and disaster preparedness strategies in the community.

Abstract
The environmental situation of our planet is seriously degraded due to the massive spread of greenhouse gases. Several aspects can influence the quality of the environment. The present study debates the effect of financial inclusion (FI) and renewable energy consumption (REC) on the emissions of carbon dioxide (CO2) emissions of the top ten countries in technological advancement (TTCTA) over the period 2004-2019. Other deterministic factors are included in the empirical study such as real gross domestic product (GDP), non-renewable energy consumption (NREC), and technological advancement (ATECH) to check their influence on environmental indicators. PMG-ARDL approach, cointegration techniques, and Granger causality tests are applied for the empirics part. In the long run, the outcomes show that real GDP, REC, and technological advancement contribute to decreasing CO2 emissions, while NREC and FI contribute to increasing emissions levels. In the short run, only GDP and NREC significantly deteriorate the environmental quality. Granger shows a long-run bidirectional causality between CO2 emissions, economic growth, REC, NREC, and ATECH.

Implications of COVID-19 on oxbow lake (Baors) Fisher's community, Bangladesh: resilience to food security against probable natural calamities. Heliyon 2022; 8:e11326. [PMID: 36339764 PMCID: PMC9624063 DOI: 10.1016/j.heliyon.2022.e11326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/23/2022] [Accepted: 10/24/2022] [Indexed: 11/06/2022] Open
Abstract
The purpose of studying the consequence of COVID-19 on oxbow lake (Baor) fisher's community is to counteract the negative impacts on livelihoods with food security and figure out diversified resilience options for sustaining basic needs of life. Individual questionnaire interviews, oral history, focus group discussion, and telephonic interviews were among the methodological techniques used to gather primary data. The Baor fisher's community was impaired with income, food and feeding habit, health and marketing. The Baor fishers had to stop harvesting or reducing the amount of fish harvest because of gradual decreasing of consumer demand and prices of fish during the course of COVID-19 pandemic period. The transportation costs were raised up to 50%–80%, while the prices of fish decreased by 15%–30% prior to the onset of COVID-19 pandemic. The frequency of fish consumption was significantly come down to 37.5%. Many households substituted fish to farm reared hens, eggs, domestic hens and ducks, lentils, and vegetables during the period of lockdown across the country. Supply chains of fish and fish culture inputswere disrupted due to inadequacy of transportation facilities. Many school- and college-going students were dropped outduring the ongoing pandemic situation due to their financial problems (10%) and early marriage (7.5%). The secondary sources of income (labor of netting in other aquaculture farms) of Baor fisher's community were also impaired. The resilience options of this study will be helpful to minimize the sudden economic crises, ensure dynamic fish value chains and food security, protect individuals from ongoing health hazards, and promote sustainable food production systems followed by social cohesion and stabilityagainst the prevailing challenges owing to the pandemic and other natural calamities.

Abstract
The COVID-19 pandemic has profoundly affected many world regions’ coastal social-ecological systems (SESs). Its extensive consequences have exposed flaws in numerous facets of society, including small-scale coastal fisheries in developing countries. To this extent, by focusing on two coastal districts in Bangladesh, namely Chittagong and Cox’s Bazar, we investigated how the lockdown during COVID-19 impacted small-scale coastal fishers in Bangladesh and which immediate measures are required to develop and implement insights, on the role of the scale of governance attributes, in facilitating or impeding the resilience of small-scale fisheries (SSFs). We analyzed both qualitative and quantitative data obtained through semi-structured, in-depth individual interviews (n = 120). Data were further validated using two focus group discussions in the study areas. The impact of the pandemic on the fishers’ livelihood included halting all kinds of fishing activities; limited time or area for fishing; livelihood relocation or alternative work; low fish price; fewer fish buyers, causing difficulty in selling; and travel or free-movement restrictions. Additionally, the study discovered several coping skills and found that the most prevalent coping strategy against the effect of the COVID-19 pandemic was to take out loans (48%) from different organizations and NGOs and borrow money from relatives, neighbors, friends, or boat owners. Finally, the current research analysis identified possible recommendations to enhance the resilience of coastal fishers during COVID-19, emphasizing arrangements that should be made to provide alternative livelihood opportunities for coastal fishermen via need-based training, technical and vocational education and training, and microcredit to keep them afloat and earning during the pandemic, not relying only on fishing.

Abstract
Scientists have recorded the impacts of the COVID-19 pandemic on small-scale fishers (SSFs), such as stagnating market demands and reduction in market price and income. Even though scientific evidence has heeded to these impacts, there is limited evidence regarding the long-term impacts and coping mechanisms of SSFs over longer periods. In addition, few studies have analysed these impacts and strategies from multiple perspectives. Our study aims to describe the perceived impacts of the COVID-19 outbreak on the communities of SSFs and the strategies adopted by them since the beginning of the outbreak in Trang Province, Thailand. Both qualitative and quantitative data obtained through semi-structured interviews indicated that, in the early stage of the outbreak, the SSFs used their natural, financial, and social capitals wisely; notably, human capitals were essential for the recovery in the later stages. Our findings suggested that an adaptive capacity to flexibly change livelihoods played an important role for the SSFs to cope with the outbreak; most importantly, our study indicated that, in a stagnating global economy, alternative income sources may not necessarily help SSFs.
