Abstract: Parasitic infections in marine fish pose economic and public health risks, particularly when zoonotic species are involved. Ribbonfish (Trichiurus lepturus), a commercially important species in Indonesia, is highly susceptible to endoparasites that may reduce fish quality and threaten human consumers. This study aimed to identify the types, prevalence, and intensity of endoparasites infecting ribbonfish landed at Paciran (Lamongan) and Tamperan (Pacitan). A total of 56 fish samples were examined through necropsy and microscopic observation of internal organs. Two nematode species, Anisakis sp. and Camallanus sp., were detected in the intestine, stomach, and muscle tissues. Prevalence was 0.2% at Paciran and 0.4% at Tamperan, while intensity reached 1.3 and 1.9 ind/individual, respectively. Infected fish were typically larger, with body weights ranging from 100–400 g and lengths of 60–80 cm, and often contained undigested small fish and crustaceans that may serve as intermediate hosts. Although infection levels were classified as low, the detection of zoonotic Anisakis sp. underscores the need for continued monitoring to prevent potential health risks and safeguard fishery resources.

Abstract: Mangrove ecosystems, distributed across tropical and subtropical coastlines, are globally recognized for their exceptional biodiversity and multifunctional ecological roles. They sustain coastal fisheries by serving as breeding and nursery habitats, support diverse terrestrial and aquatic fauna, enhance shoreline stability through wave attenuation and erosion control, and improve water quality via nutrient recycling and pollutant filtration. Mangroves are also among the most efficient blue carbon sinks, contributing significantly to climate-change mitigation. From a socio-economic perspective, they provide timber and non-timber resources, support artisanal fisheries, enable ecotourism-based livelihoods, and hold high potential for carbon-credit revenue and bioprospecting. The review synthesizes evidence from 135 studies published between 1990 and 2024, retrieved from Web of Science, Scopus, Google Scholar, and institutional repositories, based on their relevance to mangrove ecology, ecosystem services, and community-level economic benefits. Only peer-reviewed articles, technical reports, and case studies with clear methodological descriptions were included. The synthesis reveals that the ecological and economic functions of mangroves are strongly interdependent, with degradation of habitat quality directly reducing fisheries productivity, carbon storage efficiency, and livelihood security. The review highlights the urgent need for integrated management approaches, including hydrological restoration, community-based conservation, and policy-supported payment-for-ecosystem-services mechanisms, to enhance ecosystem resilience under accelerating anthropogenic and climate pressures.
