Abstract

Graphical Abstract Highlight Research Financial Well-being is the result of the interaction between cognitive factors (literacy), psychological factors (attitude, self-efficacy), and behavior, but, it is closely associated with the psychological domain. Strengthening financial literacy programs by combining practical (skills and behavior) and attitudinal (attitude toward money) components to improve FSE, which in turn enhances the FWB of fishermen in Karanggongso Coast. This research expands the financial adaptation paradox to coastal fishing communities, highlighting the unique determinants, such as cognitive, psychological, and behavioral factors that shape their financial outcomes in their pursuit of FWB. Future studies should incorporate non-financial behavior mediating variables and use financial well-being measurements that consider psychological and financial aspects to test direct and indirect pathways.   Abstract Karanggongso Coast is one of the significant hubs for capture fisheries, which serves as a buffer zone in Trenggalek, Indonesia. There is more small-scale fishing, focusing on a dual livelihood system created by its location as a favorite tourist destination. Nevertheless, the community contends with persistent financial instability, characterized by income-expenditure imbalances and vulnerability to external shocks. The study aims to analyze the relationships between financial literacy, financial self-efficacy, and financial attitude on financial well-being, with financial behavior as a mediating variable among fishers in Trenggalek Regency, East Java, Indonesia. This study used Structural Equation Modelling (SEM) – Partialy Least Square (PLS) to test the relationships between financial literacy, financial self-efficacy, and financial attitude on financial well-being, with financial behavior as a mediating variable. This research was conducted from August to December 2024. The results indicate that directly the variables FL and FSE have a significant positive effect on FWB; but FSE and FA have a significant negative effect on FB, and FL has no effect on FB. Meanwhile, the variable FB has a significant negative effect on FWB. Then it is known that FB does not mediate the relationship between these factors on FWB. Thus, this study recommends strengthening financial literacy programs by combining practical and attitudinal (attitude toward financial) components to improve financial self-efficacy, which in turn enhances financial well-being. Future research should include non-financial behavioral intervening variables, such as socio-cultural, and use of financial well-being measures that consider both psychological and financial aspects.

Abstract

Graphical Abstract Highlight Research 1. Aeromonas hydrophila PTF3 was identified and analysed as a causative agent of a previously identified hemorrhagic syndrome in Tor tambroides. 2. Lactococcus garvieae JAL37 supplementation in feed can enhance the growth of Tor tambroides fingerlings. 3. Lactococcus garvieae JAL37 can increase the resistance of Tor tambroides fingerlings to Aeromonas hydrophilla PTF3. 4. Relative mRNA levels of ghrelin, GH, and I-FABP genes were increased after 90 days of tor cultivation with Lactococcus garvieae JAL37 supplementation.   Abstract  Mahseer, or tor fish, an indigenous Asian fish of great socio-economic value, is gaining attention as it faces threats to its survival. However, slow growth rates and disease susceptibility remain significant challenges in mahseer cultivation. Feed supplemented with probiotic Lactococcus garvieae JAL37 at a concentration of 1.0 × 10⁸ CFU/g feed, twice weekly, was used in this study to evaluate its effects compared with a control. Triplicate groups of Tor tambroides fingerlings (average weight 1.86 ± 0.09 g) were cultivated for 90 days. Parameters such as growth, intestinal histology, and mRNA expression levels of growth-related genes (ghrelin and I-FABP from the intestine; GH and IGF-1 from the liver) were assessed. Day 90 post-cultivation, mahseer were challenged with an oral infection of Aeromonas hydrophila at 5.0 × 105 CFU/g fish to assess survival rate and mRNA expression levels of pro-inflammatory cytokine-related genes (TNF-α and IL-1β). Weight gain, specific growth rate, and villus length in Tor tambroides fingerlings treated with probiotics showed significant increases (P<0.05). Real-time PCR results indicated upregulated mRNA expression of ghrelin, I-FABP, and GH genes in the probiotic group, whereas IGF-1 gene expression was similar to that in the control group. Probiotic treatment significantly improves the survival rate of T. tambroides after A. hydrophila challenge, while suppressing mRNA expression of TNF-α and IL-1β genes post-challenge. These findings suggest that Lactococcus garvieae JAL37 supplementation can promote growth in Tor tambroides fingerlings and enhance disease resistance against Aeromonas hydrophila.

Abstract

Graphical Abstract Highlight Research 1. Combining DNA barcoding with morphological variation analysis can enhance the accuracy of Pufferfish species identification. 2. This is the first study to examine the genetic diversity and phylogenetic relationships pufferfish from Madura, East Java, using partial COI sequences. 3. DNA barcoding confirms the morphological identification of this group (96%-100%) 4. The reliability using targeted DNA barcoding and phenetic taxonomy to study genetic variation and identify species differences in pufferfish.   Abstract Pufferfish are one of the most common fish species in the ocean particularly in Camplong Beach, Madura. Despite the abundant nature, there isn’t much information on this species in East Java, showing the need for identification. Therefore, this study sought to identify pufferfish species in Sampang Regency through morphological and molecular characterization utilizing DNA barcoding of the COI gene. Fins were kept in 96% absolute ethanol, and DNA extraction, polymerase chain reaction (PCR), and sequence analysis were performed using bioinformatics tools, including the BOLD system and the web-based Automatic Barcode Gap Discovery (ABGD) tool. To strengthen genetic study, phenetic taxonomy was again applied using Ntysc. Morphological identification revealed five distinct species of pufferfish, namely Chelonodontops patoca, Lagocephalus spadiceus, Arothron reticularis, Otracion rhinorhynchos, and Cyclichthys orbicularis. The high haplotype diversity (Hd) of 0.9 and nucleotide diversity (π) of 0.2 indicated substantial genetic variation. There were 11 polymorphic sites, and the overall ts/tv ratio was 2.2. The frequency of parsimonious informative sites was 21.6%. The phylogenetic tree displayed distinct branching patterns among species. Morphological and molecular identification data supported these results, demonstrating that five distinct pufferfish species occur at Camplong Beach in the Sampang District of Madura.

Abstract

Graphical Abstract Highlight Research 1. This research provides initial and current information regarding seagrass on small islands right on the equator. 2. directly depicts the diversity, density and cover of seagrass in a unique region, namely a small island crossed by the equator. 3. The environmental conditions of marine waters in seagrass areas on islands crossed by the equator have been described. 4. The latest information specifically describing seagrass and the ecology of equatorial marine environments. Essential for the development of future knowledge and technology. 5. DNA barcoding was capable of resolving field identification challenges and providing taxonomic clarification based on DNA sequence data.   Abstract The equator is a hypothetical line that separates the general region from the world.  Complete information on coastal ecosystems has not been provided for seagrass in the equatorial latitudes. Seagrass is dynamically distributed throughout the equatorial latitudes. The area that the equatorial latitudes also traverse is known as the indotropic region. Eastern Indonesia's Kayoa Island is situated directly on the equator.  A problem, namely how is the biodiversity of seagrass in the equatorial region. There are no published research on seagrass, particularly on biodiversity. The aim of this study is to reveal the diversity of seagrass in equatorial latitudes on the small islands. The methodology in this study was purposive sampling with a quadrant line transect was used to obtain the samples.  In situ identification of seagrass species was done.  Seagrass samples were taken from the leaves for DNA analysis purposes. Leaf samples were analyzed molecular in the laboratory. To determine the distribution of seagrass ecology and environmental were subjected to PCA analysis. The results found that six species of seagrass.  It has been discovered that seagrass may grow and develop in the tropical region under typical environmental conditions.  Despite the fact that six species were discovered, diversity was limited.  In this region, seagrass cover is typically high and supports a healthy species density.  In general concluded that diversity and density are low but cover is still quite good. DNA barcoding has revealed differences in morphological identification.This discovery represents preliminary data that can be investigated further in subsequent studies.

Abstract

Graphical Abstract Highlight Research Liquid smoke improved growth and biomass of Kappaphycus striatus. A concentration of 2.67 mL L⁻¹ yielded the highest specific growth rate and weight gain. All treatments maintained 100% survival throughout the culture period. Liquid smoke reduced ice-ice disease incidence, indicating biostimulant potential.   Abstract Liquid smoke (LS) is an organic product derived from the condensation of natural wood smoke and is widely applied in agriculture as a fertilizer, growth enhancer, and disease-control agent. However, its potential application in seaweed farming, particularly for improving growth performance and mitigating ice-ice disease, remains poorly explored. This study aimed to evaluate the effects of different liquid smoke concentrations on the growth performance, weight gain, survival rate, and ice-ice disease occurrence in the cultured macroalga Kappaphycus striatus. A 45-day culture experiment was conducted under controlled conditions using a Randomized Completely Block Design (RCBD) with five treatments in triplicate: a control without liquid smoke (T1) and four liquid smoke concentrations, 0.67 mL L⁻¹ (T2), 1.33 mL L⁻¹ (T3), 2.00 mL L⁻¹ (T4), and 2.67 mL L⁻¹ (T5). Liquid smoke treatments were prepared by dissolving the required volume in seawater, and seaweed seedlings were soaked in the respective solutions for 10 minutes and covered overnight before deployment. Higher liquid smoke concentrations significantly enhanced seaweed performance. The highest concentration (2.67 mL L⁻¹) resulted in the greatest specific growth rate (5.70 ± 0.04% day⁻¹), which was significantly higher (p<0.05) than the control (3.41 ± 0.16% day⁻¹), and produced the highest weight gain (207.94 ± 1.96 g). Survival remained at 100% across all treatments, while ice-ice disease incidence was markedly reduced in higher liquid smoke treatments, decreasing from 28.00 ± 0.00% in the control to 6.00 ± 0.00% at the highest liquid smoke concentration, with improvements observed as early as day 15. Liquid smoke, particularly at a concentration of 2.67 mL L⁻¹, effectively enhances growth performance, biomass production, and disease resistance in Kappaphycus striatus. Further studies under field conditions are recommended to validate its long-term effectiveness and practical application in commercial seaweed farming.

Abstract

Graphical Abstract Highlight Research 1. Integration of multi-variable oceanographic parameters for mapping fishing areas. 2. Spatial-temporal dynamics based on changes in oceanographic parameters. 3. Development of upwelling index-based fishing area detection methods. 4. Optimization of fishermen's operations through the prediction of potential locations.   Abstract Sustainable management of scad stocks (Decapterus spp[A2.1].) in FMA 573 necessitates integrating satellite-based oceanographic monitoring to identify distribution zones amid complex aquatic dynamics. This study integrates satellite imagery, descriptive analysis, and spatial modeling to map oceanographic parameters and identify fish distribution zones, aimed at enhancing the monitoring and sustainable management of scad stocks in FMA 573. The research combines satellite-based oceanographic monitoring with CPUE analysis and spatial modeling to determine fish distribution based on environmental suitability. Results indicate that oceanographic conditions fluctuate seasonally, with warm waters dominating the West Monsoon and Transition-1, while higher salinity and Chl-a concentrations characterize the later seasons. Habitat suitability modeling reveals that scad potential is primarily concentrated in coastal areas during the West Monsoon and Transition-1. The spatial distribution of the scad in FMA 573 shows a preference for coastal areas with a strong dependence on oceanographic dynamics. However, a spatial-temporal discrepancy exists: while environmental suitability peaks early in the year, industrial landing data shows fishing activity concentrated offshore, peak during Transition-2. This mismatch suggests that existing catch data reflects industrial operational habits rather than the full biological potential of nearshore areas, highlighting the need for supplementary data from small-scale fishers to validate coastal PFZs. These findings provide a baseline for predictive catch modeling and seasonal spatial recommendations. Identifying the shift from coastal zones in the West Monsoon to offshore waters in Transition-1 allows for optimized fishing efforts, improved fuel efficiency, and more precise monitoring of fishing pressure.

Abstract

Graphical Abstract Highlight Research  1. Assessment of aquifer potential around vannamei shrimp ponds on the coast of Banyuwangi Regency. 2. Lithology along the coast of Banyuwangi Regency. 3. Estimation of groundwater potential around vannamei shrimp ponds on the coast of Banyuwangi Regency. 4. Aquifer depth, which is related to seawater intrusion based on aquifer layer color.   Abstract The coast of Banyuwangi Regency is an area with high human activity involving the use of groundwater in aquifers, including activities related to vannamei shrimp farming. Therefore, seawater intrusion is suspected to occur, given that this area is adjacent to the sea. To assess the potential (distribution and depth) of the aquifer and the suspected seawater intrusion around the vannamei shrimp farming area. This approach is new because the aquifer assessment is conducted around the vannamei shrimp farming area as a basis for sustainability, especially in relation to the estimated seawater intrusion around the area. Data was collected through surveys and direct observation, by dividing the measurement area vertically and horizontally. Detection was carried out using AIDU Golden Rod (AGR), including data analysis using AIDU Prospecting software. The results of the study indicate that the productivity of aquifers around vannamei shrimp ponds in Banyuwangi Regency, for water discharge between < 5 L/second - > 10 L/second, and aquifer depths ranging from 5 to 155 m, shows indications of seawater intrusion around vannamei shrimp farms. The aquifer zone includes moderate to high productivity stretching along the geological structure, where seawater intrusion has occurred around the shrimp ponds indicated in blue. Therefore, further research is needed on the analysis of seawater intrusion values as a basis for sustainable groundwater management policies.
