Preface

Abstract Pandemic COVID-19 has hardly impacted global fisheries and aquaculture, as FAO reported in the 34th session of the Committee on Fisheries (COFI) in February 2021. FAO further suggests that this pandemic impact catalyzes the fisheries sector to be more innovative, socially, and environmentally responsible. Fish and fisheries products are well-known healthy food. It contains high quality and quantity of protein and provides essential vitamins and minerals to maintain human health status. The innovation of science and technology in the fisheries sector is a crucial point to improve and assure the efficiency and sustainability of the production and utilization of the resource. Research activities and development should be synergically conducted to implement technologies that benefit the communities. Department of Fisheries, Faculty of Agriculture, Universitas Gadjah Mada, holds a biennially international symposium to provide access and exchange of research data and fisheries experience to support the transfer of knowledge and technology to strengthen the world’s fisheries sector. The 4th International Symposium on Marine and Fisheries Research (The 4 th ISMFR) aims to bring together academic scientists, researchers, government institutions, private parties, and stakeholders to share and exchange progress information, experiences, and research results in all aspects of marine and fisheries sciences. The 4th ISMFR theme was promoting sustainable fisheries through technology and research innovation for a healthy community”. It covered a broad spectrum of fisheries-related topics, including aquaculture, fish disease, fish genetics, biotechnology, marine natural product, seafood processing technology, seafood safety, fisheries biology, fisheries resources management, fisheries socio-economics, oceanography, climate sciences, and marine ecotoxicology. Due to the Pandemic COVID-19, the 4th ISMFR was held virtual on July 28-29, 2021, by using the Zoom Meeting platform. We cannot postpone this symposium because it is a routine schedule for researchers and stakeholders to disseminate and discuss their research findings. The seminar’s organizing committee was located in the Fisheries Department, Faculty of Agriculture, Gadjah Mada University, Yogyakarta, Indonesia. Management of the symposium was carried out using the website (http://ismfr-ugm.org/). The symposium consists of a plenary session and parallel presentation sessions. The plenary session presented three keynote speakers, namely Professor Rashid Sumaila from The University of British Columbia (Canada), Professor Erlinda R. Cruz Lacierda from The University of the Philippines Visayas (Philippines), and Professor Soottawat Benjakul from The Prince of Songkla University (Thailand). A total of six parallel presentation sessions was conducted with 12 invited speakers and presenters from eight countries, namely Norway, Belgium, New Zealand, Japan, Australia, Thailand, Malaysia, and Indonesia. Presentations in each parallel class were divided into presentation panels consisting of approximately five presenters. Each presenter was given 10 minutes for presentation and discussion. Discussion sessions were held at the end of each forum for about 15 minutes. A total of 146 scientific papers have been presented at the 4th ISMFR. The 4 th ISMFR was attended by 155 participants. All presenters and attendances join the symposium virtually from their respective residences. Readers can access recordings of the 4 th ISMFR Plenary session on the YouTube channel (https://www.youtube.com/watch?v=dGtjnoR3hSo&t=7599s). This proceeding provides an opportunity for readers to gain more information from the reviewed papers that have been presented in the 4th ISMFR. The articles published in this proceeding were selected from the papers presented in the symposium. The reviewers from six countries (Philippines, Egypt, Malaysia, Thailand, Japan, Indonesia) and the editors from four countries (Malaysia, Thailand, Japan, Indonesia) have participated in the abstracts screening, improving, and finalizing the manuscripts. The proceedings divided into three sections, namely aquaculture, aquatic resource management, and fish product technology. From this proceeding, readers will find recent research finding on broad aspects of fisheries and marine sciences to come up with new knowledge and idea to promote sustainable fisheries through technology and research innovation for a healthy community. We want to thank all parties for the success of the 4th ISMFR. Our gratitude is presented to the organizing committee, keynote and invited speakers, reviewers, editors, and editing staff for the dedication, hard work, and tireless efforts in implementing the symposium and publication process. We express our acknowledgment to the Rector of Universitas Gadjah Mada, the Dean of the Faculty of Agriculture, the Head of Fisheries Department, and the Publication Agency of Universitas Gadjah Mada, who provided continuous support on the symposium. Our thank you also conveyed to the speakers and participants, who have given their best efforts to disseminate, discuss, and publish papers. We also thank all parties who have contributed to the success of the 4 th ISMFR and the publication. We sincerely hope readers will find notable pieces of knowledge on fisheries and marine science from different points of view.
