The seagrass ecosystem has the same role as other ecosystem in improving coastal community fishery business. The purpose of this study is to assess the provision of seagrass ecosystem services to small fishing activities in the study sites. The research was conducted in Malang Village Meeting and Berakit from September to November 2014. Spatial distribution of fish species resources and small fishing catchment areas at study sites were located near the coast in each study village. The activity of catching small fishermen by utilizing the existence of seagrass ecosystem is reflected from the resources of fish species that are obtained and marketed to meet their needs. Fish community structure associated with seagrass from small fisherman catch in Malang Village Meeting based on index value of diversity (H ') and uniformity (E) of 2.58 and 0.93 higher than that of Desa Berakit that is 1.77 and 0.65. This value indicates that the keaganagaman in Malang Village is Medium and the community is in stable condition. While in the village of Berakit shows low diversity and community in unstable conditions. While the value of dominance index (C) of each village is low with the value of each village of 0.09 and 0.31. Keywords: seagrass ecosystem services, small-scale fisheries, and Eastern Coastal of Bintan

Seagrass ecosystem has important roles in ecological and social factors to support fisherman income. The purpose of this research was to map the social-ecological system connectivity of seagrass with small-scale fisheries with networks perspective, to identify social-ecological connectivity of seagrass with fisheries resource availability approaches in small-scale fisheries, and to estimate the benefits of fish resources relation to seagrass ecosystem in Malang Rapat and Berakit vilages. Social-ecological system connectivity of seagrass was proven by the spatial distribution of fishing areas, networks map markets, and dynamics of small-scale fisheries catches in the study site. Social-ecocoligal connectivity of seagrass was also proven by fish catches dominated by Siganidae, Scaridae, Lethrinidae, and Lutjanidae families. The fishermen income was supported by seagrass ecosystem connectivity which contributed revenue from fish catches totally Rp 202,124,00/day in Malang Rapat village and Rp. 193,151,00/day  in Berakit village. Other benefit of seagrass ecosystem located nearby the beach was that the fishermen can have an easy access or less fuel for fishing operation.Keywords: seagrass ecosystem, network map, connectivity, small-scale fisheries, social-ecological system, Riau islands

Blue Growth

By employing empirical and secondary data (qualitative and quantitative), this study demonstrates how social equity (with its three dimensions) can meaningfully address the conservation of the coastal social–ecological system (SES), without losing diverse ecosystem services (ES) in south-east coastal Bangladesh. Based on this proposition, this study assesses the available ES and identifies the drivers responsible for ES changes, arguing for the application of social equity for resource conservation. The findings show that communities along Bangladesh’s south-eastern coast use several ES for food, medicine, income, livelihoods, and cultural heritage. However, this valuable ecosystem is currently experiencing numerous threats and stressors of anthropogenic and natural origin. In particular, large-scale development activities, driven by the blue growth agenda, and neoliberalism policy, pose a risk to the local communities by degrading coastal ecosystem services. Escaping this situation for coastal natural resource-dependent communities in Bangladesh will require a transformation in the governance structure. Implementing the Small-Scale Fisheries (SSF) Guidelines that call for initiating policy change to deliver social justice to small-scale fisheries would help to address coastal ecosystem service conservation in Bangladesh.

Lower Size

Of particular concern in commercial fishing catch is 'size bycatch', i.e., the death of early stages of resources that would reach a marketable value when they turn into adults. This event is frequently associated with trawling because of the lower size selectivity of this gear as compared to gillnets. However, this is expected when small-scale fisheries (SSF) employ gillnets simultaneously in setnets + driftnets that mix multiple mesh sizes. This work analyzes fishing captures and compares characteristics of fish catch from gillnets and trawlers with respect to size at first maturation, legal size of capture, and expected discards. Data were obtained from 2007-2021 for SSF in Southern Brazil. A total of 112 fish species were represented in the data. Gillnets exploited fewer species than trawlers; however, most of these constitute fishing resources in the study region. Of the 19 species whose maturation size is known, nine occurred in gillnets as juveniles, and of the 14 species for which the legal size of capture is established, seven occurred in gillnets in prohibited sizes. Gillnets and trawlers presented size bycatch and affected different species between them, with four resources that were present in bycatch from both gillnets and trawlers. The broad range of mesh sizes employed by SSF warns of the discarding of undersized captures, and stresses the importance of policies addressing gillnet management.

Abstract Small-scale fishers are frequently exposed to a variety of hazards that threaten their livelihood. Different socio-cultural, natural resource, environment conditions potentially create unique vulnerability and livelihood strategies which may exist in different places. Therefore, an investigation in two different fishing communities was carried out to understand the similarities and different of livelihood strategy works in both places. The study was conducted in two small scale fisheries community in village Betahlawang (north of java) and Glagah (south of Java). This research aims to describe livelihood aspects and strategies of fisher communities in both locations under different fishery resource and their dependency on the fishery through systematic surveys. The study showed that both communities are highly dependent on natural capital which mainly the abundance of the fishery resources. Others factors affecting both communities’ sustainable livelihood are the uncertainty in catch, weather and policy, limited capital ownership, access, and knowledge and skills other than fishing. Although the two study sites share some capital similarities, the livelihood vulnerability and their strategy is different. Betahlawang fishers more vulnerable than Glagah fishers because Glagah fishers has more diverse livelihood alternatives.

Abstract Three species of snappers from artisanal, small-scale fisheries were examined for the presence of parasites. A total of 139 lutjanid fish were collected: 69 specimens of Lutjanus analis, 47 specimens of Lutjanus vivanus, and 23 specimens of Lutjanus synagris. Encysted plerocercoid of trypanorhynch cestodes found at necropsy in the viscera of snappers were sampled for parasitological analysis. These plerocercoid larvae belong to the genera Floriceps, Pseudogrillotia , and Oncomegas. Although these parasites do not have any zoonotic potential, fish with heavy loads of plerocercoids are rejected during inspection as they compromise meat hygiene. Our findings suggest that light larval cestode infections in lutjanids would not lead to consumer rejection of the food product. The occurrence of Floriceps sp. in L. analis and in L. synagris, of Pseudogrillotia sp. in L. vivanus and in L. synagris , and of Oncomegas sp. in L. synagris are new findings in these fish species. These parasites are new to these fish species and have not been reported in snappers from the northeast coast of Brazil. The results contribute to the existing body of knowledge about the parasitic fauna of fish and its distribution along the coastline of Brazil.
