Indonesia is a country rich in demersal and crustacean fish resources (such as snapper, grouper, crab, crab, shrimp, lobster, etc.). The high biodiversity and abundance of this group of fish resources is due to Indonesia has coral reefs, as well as extensive shallow coastal waters. The biodiversity of demersal and crustase fish resources has not been fully managed properly, even though the demersal and crustase fisheries sector contributes greatly to the country’s economy. The challenges faced by demersal and frustrated fisheries are getting tougher, ranging from population decline due to overfishing, environmental/habitat degradation, business aspects after the COVID-19 pandemic, to global issues such as climate change. The trends and scientific status of fisheries resources need to be well understood as a benchmark for scientific development and responding to future challenges. In this case, scientific forums can be one of the necessary vehicles where relevant parties can discuss various challenges, alternative solutions, and important issues that exist today and in the future in the context of developing science and sustainable management of fisheries resources. The Department of Aquatic Resources Management (ARM), Faculty of Fisheries and Marine Sciences (FFMS), IPB University took the initiative to hold the International Seminar on Demersal and Crustacean Fisheries Management (ISDCFM). The seminar was held hybrid at the IPB International Convention Center, Bogor on August 2-3, 2023. The ISDCFM was the first international seminar that emphasizes the direction and strategy of sustainable management, as well as promoting better governance of demersal and crustacean fisheries, by collecting research results in various aspects, from basic to applied science development, down to the policy and trade side. The seminar covers several topics including ecology, habitat, and conservation of the species, product and technology diversification, domestication and cultivation of the species, social-ecological systems and fisheries management, and blue economy fishing industry. The seminar was attended by six keynote speakers, 56 oral presentations, and 11 poster presentations. Presenters come from at least eight countries: Indonesia, United Kingdom, Sri Lanka, Sudan, China, Japan, and Czech Republic. The total participants of this activity were 147 participants, both national and international. Six keynote speakers were experts from various fields, including Dr. Agus Suherman from the Directorate General of Capture Fisheries MMAF, Prof. Dr. Luky Adrianto from the IPB University, Poly Burns from Marine Stewardship Council, Amber von Harten from Sustainable Fisheries Partnership, Dr. Petrus Johannes Mous from Yayasan Konservasi Alam Nusantara, and Kuncoro Catur Nugroho from Indonesian Blue Swimming Crab Association. Many new ideas, insights, methodologies, and state-of-the-art science can be studied and adopted to improve our work in this important area. There have been many interesting and useful presentations in plenary and interactive sessions. Many good experiences have been shared and lessons learned, including in the aspects of ecology, fisheries management, and social economic of demersal and crustacean resources. We would like to take this opportunity to thank all partners, namely the Department of Aquatic Resources Management (ARM IPB University), Faculty of Fisheries and Marine Sciences (FFMS IPB University), Indonesian Blue Swimming Crab Association (APRI), and Indonesian Demersal Association (ADI). Also, we would like to thank all the speakers, reviewers, and the committee for organizing this event and ensuring it runs smoothly.
