Authors: Sanchez John , Arteaga Juan , Zesiger Cody , Mitcheson Paul , Young Darrin , Roundy Shad
Published: January 2025

Field implementations of fully underground sensor networks face many practical challenges that have limited their overall adoption. Power management is a commonly cited issue, as operators are required to either repeatedly excavate batteries for recharging or develop complex underground power infrastructures. Prior works have proposed wireless inductive power transfer (IPT) as a potential solution to these power management issues, but misalignment is a persistent issue in IPT systems, particularly in applications involving moving vehicles or obscured (e.g., underground) coils. This paper presents an automated methodology to sense misalignments and align IPT coils using robotic actuators and sequential Monte Carlo methods. The misalignment of a Class EF inverter-driven IPT system was modeled by tracking changes as its coils move apart laterally and distally. These models were integrated with particle filters to estimate the location of a hidden coil in 3D, given a sequence of sensor measurements. During laboratory tests on a Cartesian robot, these algorithms aligned the IPT system within 1 cm (0.025 coil diameters) of peak lateral alignment. On average, the alignment algorithms required less than four sensor measurements for localization. After laboratory testing, this approach was implemented with an agricultural sensor platform at the Utah Agricultural Experiment Station in Kaysville, Utah. In this implementation, a buried sensor platform was successfully charged using an aboveground, vehicle-mounted transmitter. Overall, this work contributes to the field of underground sensor networks by successfully integrating a self-aligning wireless power delivery system with existing agricultural infrastructure. Furthermore, the alignment strategy presented in this work accomplishes coil misalignment correction without the need for complex sensor or coil architectures.

Authors: Iten Raphael , Wagner Joël , Röschmann Angela Zeier
Published: January 2025

Smart homes offer promising opportunities for risk prevention in private households, especially concerning safety and health. For instance, they can reduce safety risks by detecting water leakages quickly and support health by monitoring air quality. Current research on smart home technology predominantly focuses on usability, performance expectations, and cyber risks, overlooking the potential importance of risk prevention benefits to prospective users. We address this gap by utilizing data from a recent survey to construct a structural equation model. Our overarching hypothesis is that prevention benefits and comfort considerations positively influence adoption. The results confirm the relevance of comfort, as suggested by previous research. In addition, the results reveal significant prevention benefits in safety and health, which are positively related to technology expectations and the intention to adopt smart homes. Furthermore, newly included variables such as technology affinity and active aging lifestyle emerge as indicators of potential smart home users, extending the knowledge of user characteristics beyond traditional sociodemographic indicators. The findings contribute to filling a gap in the current risk and technology literature and are also relevant for smart home device manufacturers and risk and insurance practitioners looking to evolve their business models.
Application of Mealworm Frass in Organic Seedling Production of Allium cepa L., Beta vulgaris L., and Brassica rapa L.
Authors: Baldacchino Ferdinando , Lamaj Flutura
Published: January 2025

Horticulture is mainly based on transplanting seedlings produced by specialized nurseries. The recent European authorization of frass in organic farming presents new opportunities for the development of organic seedling production. Frass, a by-product of insect farming, offers innovative solutions for this sector. It mainly consists of insect excrement, exuviae, and uningested feed. Their fertilizing and biostimulating effects have been demonstrated in various pot and field crops experiments. However, the current knowledge regarding the application of frass in seedling production remains insufficient. This study aims to assess the optimal dose of mealworm frass in germination substrates for Allium cepa L., Beta vulgaris L., and Brassica rapa L. Germination and phytotoxicity tests were carried out, with seedlings evaluated one month after sowing in substrates containing frass at concentrations of 0.5%, 1%, 2%, and 3% of frass. The germination test revealed that the dilution of the frass at 1:100 produced a phytostimulant effect on A. cepa and a moderate phytotoxic effect on B. vulgaris and B. rapa. The application of mealworm frass at a concentration of 0.5–1% was generally the most effective dose, although all doses of frass in the substrate resulted in seedlings whose root length, leaf length, number of leaves, and biomass were significantly higher than the control. In conclusion, the application of low doses of mealworm frass in organic seedling production is promising and allows the management of potential phytotoxicity.
When Silence Speaks: Public Service Innovation, Village Authority, and the Negotiation of Traditional Justice in Rural Indonesia’s Youth Protection System

Published: January 2025

Rural Indonesian villages are defined by unique institutional dynamics in public service innovation, one of which manifests in juvenile justice administration where traditional governance meets modern legal structures. These institutional arrangements position villages as sites of public service innovation at the intersection of competing normative orders, especially regarding youth protection standards and cultural practice maintenance. We address patterns of public service innovation and institutional adaptation in rural juvenile justice systems through the systematic analysis of practices across five villages in East Java. Through consolidating stakeholder interviews and justice proceeding observations, our analysis shows how communities innovate in public service delivery by negotiating between formal requirements and informal mechanisms while integrating distinctive legal traditions and maintaining institutional legitimacy across multiple domains. The examination identifies two central patterns in public service development. First, processes of normative integration emerge through systematic institutional synthesis where communities innovate service delivery approaches while preserving cultural coherence. Second, these innovation processes correspond to variations in resource distribution, traditional authority configurations, and state presence across geographic and social contexts. We document how unspoken institutional practices and innovative service arrangements shape justice negotiations between community and state spheres, particularly in mediating youth protection within traditional normative frameworks of public service delivery.

Published: January 2025

The elements of body composition and their correlation with physical activity, body image, and self-esteem are aspects that require in-depth studies. This link should be seen in the context of the percentage of adipose tissue, which can be modeled via physical activity. The objective of this study is to evaluate the relationships between the parameters that define body composition, self-esteem, body image, and physical activity according to gender. This study included 100 females and 100 males with an average age of 22 years. The evaluation included anthropometric parameters, body composition, self-esteem, physical activity index, and body image perception assessment. The results show that the males exhibited a higher percentage of exceeding the upper limit of normal and average weight; in contrast, there were two times more females exhibiting normal weight than those exceeding the upper limit. Therefore, obesity was higher among males. The average fitness score values were 69.07 for females and 76.53 for males, and the mean fitness was within normal limits. Regarding body image, according to the BSQ, we observed that both groups were not satisfied with and were concerned about their body shape. With respect to the Rosenberg self-esteem scale, the average score for females was 20.27, and for males, it was 19.60; the mean self-esteem value was 66% of the maximum value. In terms of the perceived ideal body size assessed with the Silhouette scale, most of the females were placed at level 3, and the males were placed at level 4. Regarding the physical activity index, females carried out on average 1.5 days of intense physical activity over 7 days, and males were involved in intense physical activity for 2 days. Conclusions: The degree of obesity and therefore the risk of developing cardiovascular disease and metabolic syndrome were higher in males than in females. Although males have a higher degree of obesity, self-esteem is quantified at a higher level of confidence.

Published: January 2025

The aim of this study was to determine if the changes in plasma insulin, glucose (GLU), fructosamine (FRUCT), adrenocortical hormone (ACTH), and cortisol (CORT) concentrations in mares of different ages were substantial enough to indicate the need to also establish specific reference intervals for pregnant Spanish Purebred mares with a heterogeneous body conditional score (BCS). A total of 45 mares were used in the study, which were classified according to age into 24 <10 years (from 4 to 9 years) and 21 >10 years (from 10 to 18 years). According to the BCS, mares <10 and >10 years were distinguished into three groups as follows: underweight (BCS < 4–5; n = 8), moderate (BCS = 6–7; n = 8), and overweight (BCS = 8; n = 8) (BCS < 4–5 (n = 7), BCS = 6–7 (n = 7), and BCS = 8 (n = 7)), respectively. The main results of this study were that (I) circulating insulin, GLU, FRUCT, ACTH, and CORT concentrations were altered throughout the whole duration of pregnancy in mares; that (II) aging and BCS significantly affected insulin, ACTH, and CORT changes; and that (III) ACTH-CORT significantly correlated with insulin, FRUCT, and GLU. The results may have implications for health and disease and warrant future prospective investigations on the bidirectional interaction between insulin and the hypothalamus–pituitary–adrenal (HPA) axis in equine species, affecting the GLU and FRUCT profile through the entire physiological pregnancy.

Published: January 2025

The building and construction sector remains largely climate-unfriendly as a significant global greenhouse gas emitter. Public buildings can play a significant role in promoting sustainability practices. Unlike developed countries that have successfully promoted sustainable building practices, developing countries have experienced slow progress in implementing sustainable practices in public buildings. This research study investigated the challenges and opportunities for improving sustainability practices in public buildings from a multi-stakeholder perspective within the context of developing countries. Using Indonesian public buildings as a case study, a wide range of stakeholders directly involved in the public building sector such as policy-makers, building owners, building professionals, and building users were interviewed over two time periods of 2019 and 2023. The interview results show consistent findings on challenges and possible opportunities with respect to regulation, occupant behavior, and the primacy of technical intervention in the practice of sustainable buildings. Despite the importance of strong policy and the role of technology in sustainability practices in public buildings, this study advocates the need for greater intervention in occupant behavior so that sustainable practices in public buildings can be continuously promoted.
Exploring the Impact of Obesity and Insomnia on Work Productivity: Insights for Occupational Health and Sustainability in the Workplace
Authors: Malta Ginevra , Plescia Fulvio , Cannizzaro Emanuele
Published: January 2025

Background: The prevalence of obesity and sleep disorders within the Italian workforce mirrors a global trend where sedentary lifestyles, poor eating habits, and elevated stress levels significantly contribute to these health issues. These conditions have profound economic implications, including rising healthcare costs and diminished productivity due to absenteeism and presenteeism, adversely affecting organizational sustainability and employee well-being. Addressing these problems necessitates a holistic approach that integrates individual health interventions, workplace policies, and broader societal changes to promote healthy lifestyles. This cross-sectional study examines the influence of obesity and insomnia, both individually and combined, on work productivity within the context of occupational health and sustainability. Materials and Methods: A cross-sectional analysis was conducted with 397 participants from various professions over a six-month period. Self-reported work productivity impairments were assessed using the Work Productivity and Activity Impairment (WPAI) questionnaire. Body Mass Index (BMI) and Insomnia Severity Index (ISI) scores were utilized to evaluate obesity and insomnia levels, respectively. Results: Statistical analyses revealed a significant association of higher BMI and ISI scores with reduced work productivity. Both obesity and insomnia independently and synergistically contributed to productivity losses, with obesity exerting a more substantial effect. These findings indicate that obesity and insomnia increase presenteeism, thereby negatively impacting organizational performance and workplace sustainability. Conclusions: Our study underscores the critical impact of obesity and insomnia on work productivity and highlights the necessity of addressing these health issues not only for individual well-being but also for organizational sustainability. Integrating targeted health management strategies within workplaces to address these conditions can enhance productivity, improve employee well-being, and promote occupational health and safety. These interventions align with the current concept of sustainable work and are essential steps toward achieving sustainability in the workplace.

Published: January 2025

In this article, a conceptualization is proposed of regenerative rural development (RRD) based on a literature review and bibliometric analysis conducted using Web of Science and Scopus. Trends in authors, articles, and institutions related to rural development and regeneration are analyzed. The analysis, performed with VOSviewer and Bibliometrix, reveals that RRD is an emerging paradigm with a multidimensional approach aimed at healing the devastation caused by extractive models. The methodology utilized the PRISMA methodological framework and bibliometric analysis. The results demonstrate an upward trend in intellectual production related to regenerative processes in rural areas. Anglo-Saxon countries are the most prolific publishers on the subject, but there is emerging interest from countries such as China and Spain in relation to RRD. Finally, the conclusions focus on defining RRD as a multidimensional process of co-evolution and systemic interrelation that heals the devastation caused by extractive approaches in rural areas and promotes the health of living systems in the ecosystem at different scales and multidimensionally in rurality.

Published: January 2025

Spatial genes represent the fundamental interplay among the morphological characteristics of historical districts. Identifying and analyzing these morphological elements can enhance our understanding of urban spatial development, uncover spatial meanings, and provide informed recommendations for future development. This study focuses on the Xuzhou Huilongwo historical district, employing geographic information system, Global Mapper, and other digital technologies to determine the area’s microtopographic features. Qualitative methodologies extract the spatial genes of street segments, entry spaces, and node spaces. By summarizing the microtopography’s influence on street and alley characteristics, valuable spatial samples were selected and visually represented for analysis. This included examining the street segment interface, entry space sequences, and the planar morphology of node spaces. The findings reveal that Huilongwo architecture aligns with topographical features, exhibiting a multi-directional distribution. Height differences help establish street boundaries and enhance pathways’ experiential quality. Additionally, topography significantly influences street spaces, leading to undulating sequences in entry spaces. This study provides insights into the preservation and enhancement of streets and alleys within Xuzhou’s historical district.

Published: January 2025

To address poor real-time performance and low accuracy in car-following risk identification, a model based on autoencoders is proposed. Using the SHRP2 natural driving dataset, this paper constructs a car-following risk identification model in two stages. In Stage 1, a deep feedforward neural network autoencoder reconstructs preprocessed multi-source heterogeneous indicators of human-vehicle-road-environment. The high-dimensional latent space feature representation is used as input for Stage 2, enhancing the basic model’s performance. Eight basic models and sixteen models with autoencoders are compared using multiple evaluation indicators. A simulated driving test verifies the model’s generalization and robustness. Results show improved accuracy in car-following risk identification, with the optimized AutoEncoder_LR performing best at 91.33% for risk presence and 70.14% for risk levels. These findings can aid in safe driving and rear-end accident prevention.

Published: January 2025

Acrylamide (ACR) is a commonly used organic compound that exhibits evident neurotoxicity in humans. Our previous studies showed that the mechanisms of ACR-caused neurotoxicity included apoptosis, PERK-mediated endoplasmic reticulum stress, and autophagy, but the relationships among them were still unclear. This paper investigated the relationships among apoptosis, autophagy, and the PERK pathway to demonstrate the mechanism of ACR neurotoxicity further. Different doses of ACR were set to value ACR toxicity. Then, a PERK inhibitor and autophagy inhibitor, GSK2606414 and 3-methyladenine (3-MA), were used separately to inhibit the PERK pathway and autophagy activation in SH-SY5Y cells under ACR treatment. With the increase of ACR dose, the apoptotic rate increased in a dose-dependent manner. After the inhibition of the PERK pathway, the activated apoptosis and autophagosome accumulation caused by ACR were alleviated. Under 3-MA and ACR treatment, the autophagy inhibition deteriorated apoptosis in SH-SY5Y cells but had no significant effect on ACR-induced PERK pathway activation; thus, PERK pathway-induced autophagy had an antiapoptotic role in this condition. This paper provides an experimental basis for exploring potential molecular targets to prevent and control ACR toxicity.

Published: January 2025

To establish a rapid and sensitive detection method for the porcine reproductive and respiratory syndrome virus (PRRSV), gene-specific primers and a TaqMan probe were designed based on the M gene of PRRSV, and a new stable fully pre-mixed reverse transcription real-time fluorescence quantitative PCR (RT-qPCR) reaction mixture was developed. A simple and rapid RT-qPCR detection method for PRRSV was developed by optimizing nucleic acid amplification conditions. The results showed that the method was able to specifically detect PRRSV without cross-reactivity with the other 11 porcine susceptible viruses. The sensitivities of the assay were 3.12 × 100 copies/μL and 100 TCID50/μL for M gene and virus, respectively, and the repeatability and reproducibility (relative standard deviation, CV) of the assay were less than 2.5%. Based on the new fullly pre-mixed RT-qPCR reaction mixture, the RT-qPCR detection method may provide a new, simple, and rapid method for accurately detecting PRRSV.

We aimed to evaluate the reproductive efficiency of Nelore cows in fixed-time artificial insemination (FTAI) programs with early resynchronization. A total of 468 Nelore cows were divided into two experimental groups: R30—conventional resynchronization at 30 days (n = 234); R22—early resynchronization at 22 days (n = 234). Both groups followed a synchronization protocol using intravaginal progesterone devices combined with the administration of steroids and gonadotropins. The R30 protocol involved resynchronization 30 days after FTAI, while the R22 protocol implemented early resynchronization 22 days after FTAI without prior pregnancy diagnosis. In both groups, one FTAI was followed by two resynchronizations. The results showed similar pregnancy rates between the groups, with the pregnancy rate in the 1st FTAI being 50.85% in the R30 group and 48.72% in the R22 group (p = 0.742). During the 1st resynchronization, the rates were 45.22% in the R30 group and 46.67% in the R22 group (p = 0.742). The cumulative pregnancy rate after the 1st FTAI, 1st, and 2nd resynchronizations was 80.77% in the R30 group and 82.91% in the R22 group (p = 0.643), with no significant difference observed. Follicular dynamics were also monitored, with ovulation occurring in 78.95% of cases in the 1st FTAI, 91.67% in the 1st resynchronization, and 88.98% in the 2nd resynchronization. The mean diameter of the ovulatory follicle was 13.64 ± 3.48 mm, and the largest follicle diameter was significantly greater (14.47 ± 2.76 mm) in cows that ovulated compared to those that did not (11.54 ± 4.24 mm) (p < 0.05), reinforcing the association between follicle size and the likelihood of ovulation. These findings indicate that both early and conventional resynchronization protocols perform similarly, with early resynchronization offering advantages in reducing the calving interval. Furthermore, the relationship between follicular diameter and ovulation confirms the importance of follicle size as an indicator of reproductive success.
Global Sensitivity Analysis of Slope Stability Considering Effective Rainfall with Analytical Solutions
Authors: Xia Chuan-An , Zhang Jing-Quan , Wang Hao , Jian Wen-Bin
Published: January 2025

Rainfall-induced landslides are widely distributed in many countries. Rainfall impacts the hydraulic dynamics of groundwater and, therefore, slope stability. We derive an analytical solution of slope stability considering effective rainfall based on the Richards equation. We define effective rainfall as the total volume of rainfall stored within a given range of the unsaturated zone during rainfall events. The slope stability at the depth of interest is provided as a function of effective rainfall. The validity of analytical solutions of system states related to effective rainfall, for infinite slopes of a granite residual soil, is verified by comparing them with the corresponding numerical solutions. Additionally, three approaches to global sensitivity analysis are used to compute the sensitivity of the slope stability to a variety of factors of interest. These factors are the reciprocal of the air-entry value of the soil α, the thickness of the unsaturated zone L, the cohesion of soil c, the internal friction angle ϕ related to the effective normal stress, the slope angle β, the unit weights of soil particles γs, and the saturated hydraulic conductivity Ks. The results show the following: (1) The analytical solutions are accurate in terms of the relative differences between the analytical and the numerical solutions, which are within 5.00% when considering the latter as references. (2) The temporal evolutions of the shear strength of soil can be sequentially characterized as four periods: (i) strength improvement due to the increasing weight of soil caused by rainfall infiltration, (ii) strength reduction controlled by the increasing pore water pressure, (iii) strength reduction due to the effect of hydrostatic pressure in the transient saturation zone, and (iv) stable strength when all the soil is saturated. (3) The large α corresponds to high effective rainfall. (4) The factors ranked in descending order of sensitivity are as follows: α > L > c > β > γs > Ks > ϕ.
The Utilization of Dissolved Organic Matter Spectral and Molecular Properties in Freshwater Eutrophication Studies: A Mini Review

Published: January 2025

Eutrophication is a major environmental issue affecting freshwater ecosystems worldwide. While its impact on the composition of dissolved organic matter (DOM) is well recognized, the relationships between DOM’s optical and molecular properties across eutrophication gradients remain underexplored. This review synthesizes recent research on DOM’s optical properties (derived from UV-Vis absorption and fluorescence spectroscopy) and molecular characteristics (analyzed using Fourier-transform ion cyclotron resonance mass spectrometry, FT-ICR MS) in freshwater systems of varying trophic states. Generalized additive model (GAM) analysis was used to assess correlations between DOM’s properties and the trophic state index (TSI). The dissolved organic carbon (DOC), a254, SUVA254, SR, HIX, BIX, and FI averaged 11.44 ± 11.97 mg/L, 23.23 ± 16.95 m−1. 2.98 ± 0.99 L·mg−1·m−1, 1.42 ± 0.38, 2.38 ± 1.31, 1.08 ± 0.16, and 2.11 ± 0.44, respectively, from mesotrophic to middle-eutrophic sites. The GAM results revealed a significant linear correlation between DOC and DOM’s optical properties, including a254, SUVA254, and FI, with the TSI, suggesting that DOM accumulation intensifies with eutrophication. DOM’s molecular properties, such as O/C and H/C ratios, double bond equivalents (DBEs), and CHOS% content, exhibited nonlinear correlations with the TSI. These trends imply a shift in DOM sources from terrestrial and macrophyte-derived inputs to those dominated by algal- and sediment-derived sources as eutrophication progresses. We concluded that DOM’s molecular indices alone may not serve as a reliable indicator of freshwater trophic states; future studies should focus on integrating both optical and molecular indices to offer a more comprehensive assessment of freshwater trophic states. Given the limited number of molecular variables examined in this study, this work only offers a preliminary investigation into the relationship between DOM molecular changes and freshwater eutrophication. More systematic studies focusing on the molecular-level analyses of DOM across varying trophic states on a broader geographic scale are needed.

Published: January 2025

Os biofilmes são comunidades de células microbianas envoltas por uma matriz de exopolissacarídeos (EPS), que é responsável pela adesão dos microrganismos a superfícies. Um microrganismo que frequentemente produz essa estrutura e persiste em plantas de processamento na indústria alimentícia é a Listeria innocua. Este estudo avaliou a capacidade de Listeria innocua de formar biofilme em superfícies de polipropileno sob diferentes temperaturas (7°C, 27°C, 37°C e 42°C) ao longo de cinco dias. Para a quantificação dos biofilmes, foram utilizados os meios Ágar Listeria de Ottaviani & Agosti (ALOA) e Ágar Oxford (MOX), ambos empregados na detecção de Listeria spp. Os resultados mostraram que houve desenvolvimento de biofilmes em todas as temperaturas testadas, com contagens significativamente mais altas observadas a 27°C e 37°C. Isso sugere que essas faixas de temperatura são ideais para a formação de biofilmes por Listeria innocua. Essas condições térmicas coincidem com aquelas frequentemente encontradas em áreas de processamento de alimentos, o que aumenta o risco de contaminação cruzada e a persistência de microrganismos em superfícies de contato com alimentos.

Published: January 2025

Los procesos coactivos iniciados en Ecuador desde 2016, tras la implementación del Código Orgánico General de Procesos, carecen de un marco normativo que regule los plazos para la declaración de su prescripción. Este vacío legal genera inseguridad jurídica al no establecer tiempos claros, afectando el debido proceso y vulnerando la garantía constitucional de seguridad jurídica. El presente estudio busca proponer un marco normativo claro para regular la prescripción de estos procesos, garantizando la certeza jurídica y previniendo situaciones de indefensión. A través de un análisis histórico-lógico y deductivo, se evaluaron 20 procesos coactivos, identificando cómo la ausencia de regulación impacta negativamente en los derechos de los ciudadanos. Los hallazgos subrayan la necesidad de reformas legales para asegurar la equidad y el cumplimiento del debido proceso.
Analysis of Gillnet Fishery Business for Narrow-Barred Spanish Mackerel and Indo-Pacific Mackerel: Lesson Learned From KUB Kampung Baru in Muara Kintap, Indonesia
Authors:   Faculty of Fisheries and Marine Science, Lambung Mangkurat University, Indonesia, AHMADI AHMADI
Published: January 2025

This study sheds light on the business sustainability of the gillnet fishery for narrow-barred Spanish mackerel (Scomberomorus commerson) and Indo-Pacific mackerel (Scomberomorus guttatus), locally called "Tenggiri" and "Kembung," respectively, undertaken by the Kelompok Usaha Bersama (KUB) Kampung Baru, a collective business group in Muara Kintap, Indonesia. Employing a descriptive approach, we analyse the fisher group's financial performance, profitability, marketing channels, gap and challenges. Key findings reveal a thriving operation. Over 327 tons of fresh and dried mackerel were procured across 216 fishing trips involving 18 vessels. Fish prices varied along the supply chain, with producers earning USD1–7 kg-1 and wholesalers fetching USD2–8 kg-1. This fisher group generated a substantial annual profit of USD488,346 year-1, translating to roughly USD43,882 vessel-1 year-1. Strong financial indicators further reinforce this success. A healthy return on investment (R/C ratio of 1.48) and a rapid payback period (0.63 years) demonstrate viability. Positive net present value (NPV) of USD1,417,004, net benefit-cost ratio (NetBCR) exceeding 1 (6.91), and an impressive internal rate of return (IRR) of 159 % confirm financial feasibility. Vessel owners enjoyed a substantial monthly income of USD2,438 trip-1 vessel-1, significantly exceeding the provincial minimum wage of USD172 month-1. The producer-wholesaler-consumer marketing channel functioned efficiently, with margins ranging from 9 to 40 % and fishers retaining a significant share (60–91 %). These findings also highlight the underexploited potential of the mackerel fishery to bolster fishery processing businesses. The fisher group’s success story exemplifies the potential for good profit margins, swift returns on investment, and the establishment of sustainable practices within the industry.

Aplocheilus species, often known as killifishes, are popular in the aquarium trade and are used as biological control agents for mosquito larvae. They are endemic to Madagascar, Seychelles, and South-East Asia. Aplocheilus species were collected from the Attanagalu River in Sri Lanka, identified using morphological and meristic characters and subjected to truss analysis. The genomic DNA of fresh muscle tissues of 10 fish with different morphological features was amplified by targeting the Cox1 gene with FishF1 and FishR1 primers. The amplicons were sequenced and subjected to DNA homology search and phylogenetic analysis. According to morphological identification, A. dayi and A. parvus were identified, but the truss analysis did not differentiate between the two species. According to a homology search, out of eight sequences, two were best matched with A. werneri and the rest with A. blockii and phylogenetic analysis formed two separate clusters for two species. We propose that the two individuals showed a closer genetic relationship with A. werneri as A. dayi and those who showed a closer genetic relationship with A. blockii as A. parvus. Sequence diversity observed within the proposed two species revealed that intraspecies genetic variation exists in the two populations in the Attanagalu River. The present study suggests the presence of A. dayi and A. parvus in the Attanagalu River basin, along with the intraspecies genetic variations among individuals within species regarding the mitochondrial Cox1 gene.

Otolith shape analysis is an effective method that has been used to separate stocks based on their phenotypic traits. The brown-striped snapper, Lutjanus vitta (Quoy and Gaimard, 1824), is an important component of the fish catch in Iligan Bay, Mindanao, Philippines. Trends in catch and catch per unit effort, however, had been declining because of overfishing of this economically significant species as a result of continuous human exploitation. To accurately identify and manage fish, one must be aware of the stock structure of a species. The aim of this study was to contribute to the knowledge on the stock identification of L. vitta using otolith morphometrics and shape analysis. A total of 90 individuals of L. vitta were collected from the three selected sampling locations in Iligan Bay: Iligan City, Kapatagan, and Oroquieta City. Results of ANOVA tests investigating otolith shape differences between areas showed that mean values among sites differed significantly for the following shape indices: ellipticity (F = 20.93, P < 0.001), aspect ratio (F = 19.45, P < 0.001), and circularity (F = 24.72, P < 0.001). A canonical analysis of principal components verified the separation of otolith morphometric parameters among locations, with 73.9 % of the variation explained by the first axis (PC1). However, otolith shape did not differ significantly between sexes (P > 0.05). Furthermore, the differences in otolith shape among the three locations suggests a spatial structuring of L. vitta in Iligan Bay (P = 0.001) and necessitates local management and policies to enable sustainable management of the fisheries.
