With its vast archipelago, Indonesia is home to numerous rivers, lakes, reservoirs, and wetlands that support diverse and productive inland fisheries. These resources are vital not only for the livelihoods of millions of Indonesians but also for ensuring food security and sustaining the rich biodiversity that thrives in these aquatic ecosystems. The book, “The Facets of Inland Capture Fisheries in Indonesia,” is a culmination of years of dedicated research, fieldwork, and collaboration among various stakeholders. It aims to provide a comprehensive overview of the current state of inland fisheries in Indonesia, offering valuable insights into their management, challenges, and opportunities for sustainable development. This publication is made possible through the support of the Southeast Asian Fisheries Development Center (SEAFDEC) and the Inland Fishery Resources Development and Management Department (IFRDMD). We are particularly grateful to the Government of Japan, whose sponsorship through the Japanese Trust Fund VI Phase 2 has been instrumental in bringing this project to fruition. We would also like to extend our deepest gratitude to the SEAFDEC Secretariat, all SEAFDEC Departments, and the numerous researchers, practitioners, and contributors who have dedicated their time and expertise to this work. Your collective efforts have been crucial in compiling the knowledge and experiences presented in this book. Inland capture fisheries are a critical component of Indonesia’s Blue Economy, contributing significantly to the well-being of communities, especially in rural and remote areas. As we navigate the complexities of sustainable fisheries management, this book serves as both a resource and a call to action.It underscores the need for continued research, informed policy-making, and collaborative efforts to ensure the sustainability and prosperity of inland fisheries in Indonesia. We hope that this publication will not only inform but also inspire policymakers, researchers, and practitioners to take meaningful steps toward the sustainable management of inland capture fisheries. It is our sincere hope that the knowledge and insights shared within these pages will contribute to the betterment of our fisheries and the communities that depend on them. Thank you for your interest in this important work, and we look forward to the positive impact it will have on the future of inland fisheries in Indonesia.

A field guide for glass eel species identification Suryati, Ni Komang; Muthmainnah, Dina; Suzuki, Toshiya; Kasim, Kamaluddin; Pamungkas, Yanu Prasetiyo; Mulyani, Yenni Sri; Daryani, Ayu; Septimesy, Annisa; Shimizu, Tomohito Romana-Eguia, Maria Rowena Anguillid eels are unique catadromous fishes categorized as a group of species that undergo long-distance migrations, traveling between growth habitats in freshwater environments while breeding and spawning in far-deep oceanic areas. Currently, stocks of temperate eels are known to have dramatically decreased since natural and anthropogenic factors have created severe impacts on wild populations. To meet market needs, people have been looking for substitutes by using other eels that inhabit the tropics. Most of the production in the eel culture industry is realized through the rearing of wild-caught juveniles called “glass eels.” For this reason, since the mid-1990s, capture fisheries with particular interest in glass eels have increased rapidly. Previous studies identifying the Anguillid eel species in Southeast Asia were focused on looking at specific pigmentation patterns and morphological characteristics. Nevertheless, it was still hard to identify the glass eels with the naked eye. In the field, the fishers and consolidators will separate the glass eels into only two species: Anguilla bicolor and Anguilla marmorata. However, this is not very clear since some species, such as A. bengalensis and A. luzonensis, look like A. marmorata. Therefore, this field guide will describe visual observations of anguillid eels from the wild to enable the identification of glass eel species based on differences in morphological characteristics.

Besides the strategic position, Indonesia also has large resources in land and sea territory. Indonesia has become one of the top countries with the largest biodiversity in the world. With two-thirds of the water area by the total territory of countries, Indonesia is rich with flora and fauna, including aquatic species in the sea and freshwater ecosystems. Freshwater and inland waters become essential habitats for human life, especially for rural people who live on the border of rivers. Indonesia's inland water consists of a large river basin that flows and forms a special habitat such as floodplain, lakes, oxbows, and reservoirs for the artificial habitat. The identical structure formed for each habitat based on its forming process and location made it potential for the growth of endemic fish populations and other species. Inland waters are land that is formed by flooded of water for a while or in stable condition. The flooded land has dynamic water and it flows or stays for a moment such as a river, reservoir, lake, swamp, floodplain, and other flooded areas. Indonesia has 54 million hectares of inland waters consisting of 0.05 million hectares of reservoirs, 1.8 million hectares of lakes, 12 million hectares of rivers and floodplains, and 39.5 million hectares covered by swamps (Kartamihardja et al., 2017). Besides the large potential of inland water in Indonesia, the statistic has recorded around 7,977 river basins, 1,144 main rivers, 312 large dams, 322 lakes, and more than 5,000 large flooded areas (Direktorat Sumberdaya Air, 2021). The inland waters are multipurpose areas with various human activities. Human life and needs cannot leave freshwater sources for daily consumption. It does not include the activities through the water bodies for transportation, settlement, recreation, and support for farming, planting, and mining (Kolding & Zwieten, 2014). Many kinds of activity remain pollutants and excess material. It makes the rise of risk and threatens fish resource lives that face environmental pressure and extinction. The change in the environmental quality of water, poisoning, pollutant accumulation, and unfriendly fishing activity were the main issues for developing sustainable fish resources (Welcomme et al., 2010). The utilization of inland water resources always involves many sectors and fishery will be a part that is impacted by the excess of all activities. The government of Indonesia has regulated the activities and utilization of inland water resources for the welfare of society to sustain them for the next generation. One of the regulations for fisheries management is Act Number. 31year 2004, which was amended by Act Number 45-year 2009. On the technical implementation, the Act regulation has been interpreted by The Marine Affairs and Fisheries Minister Decision (PermenKP) Number 29 year-2016, about the arrangement of planning for fishing and exploitation of inland waters resources. The regulation said the ways for a technical guideline for fishing and exploitation to optimize the resource utilization, continuity, and sustainability of inland fishery resources. Besides of two regulations, the Minister of Marine Affairs and Fisheries also decided the technical regulation on PermenKP Number 9 in the year 2020, that divided the inland water territory of Indonesia into 14 parts called “Wilayah Pengelolaan Perikanan Perairan Darat (WPP-PD)” (Figure 1). With this regulation, the government can manage the potential of fisheries resources based on the stock unit by the dominant ecosystem located in each area. The inland fishery has related to the geographic condition that varies and is identic by the topography of the land. This demarcation of the area also introduces the unit stock of fish resources that are exploited in each plain area. One of the potential areas with a large swamp in Indonesia is located in South Sumatra and it is placed in 438 WPP-PD areas. The 438 WPP-PD includes five provinces they are Lampung, South Sumatra, Jambi, Riau, and Bangka-Belitung. The 438 WPP-PD has a similarity of habitat typology dominated by large and long rivers that flows to the Java Sea on the east part (Husnah et al., 2019). These rivers give specific characteristics to the border sides with a wide area of the floodplain and peat land on the downstream and middle areas. The floodplain is characterized with low acidity water pH, shallow water, and low dissolved oxygen. It will dramatically change with water fluctuation and rainfall rate. The unique habitats are supposed to have the different characteristics of fish inside of this habitat. They can live with the high stress of low pH acidity and dissolved oxygen. The freshwater commodity also has high economic value for food and consumption for local people.

Pengilar Pengilar is a fishing gear with the working principle of trapping fish so they can't get out. The main material for making it is bamboo or rattan. The entrance of the trap is commonly called “injab” and another escape vent to take the fish caught. Because it has a shape like a taro leaf, this tool is also often called a taro leaf trap. It's one of the environmentally friendly fishing gears, with the ISSCFG classification code 08.2.0, categorized as trap fishing gear. To attract fish into the trap, worm bait, bycatch, and other baits are used. The bait is placed in the bag and hanged in the trap. The trap will be checked twice a day to ensure the fish caught still survive. It's usually operated in shallow waters, on the banks of rivers, swamps, valleys, and canals. Part of the body of the trap is covered with grass, tree branches or something else to cover the t o o l .
