With regard to the development of data collection on demersal fisheries in Indonesia and particularly in PANTURA, a pocket book on species identification was published. The publication of this book is intended to facilitate the parties involved in data collection (enumerators, students, volunteers, fishermen) in terms of species identification. Species included in this pocket book include grouper (Plectropomus leopardus, Plectropomus maculatus, Epinephelus coioides, Cephalopolis miniata, Cephalopolis cyanostigma, Cephalopolis sonnerati, Epinephelus areolatus, Epinephelus ongus, Epinephelus sexfasciatus, dan Variola albimarginata), snapper (Lutjanus malabaricus, Lutjanus gibbus, Lutjanus sebae, Lutjanus vitta, Lutjanus lutjanus, Lutjanus bohar, Aphareus rutilans, Pinjalo pinjalo), threadfin bream (Nemipterus nematophorus, Nemipterus nematopus, Nemipterus furcosus, Nemipterus japonicus, Scolopsis taenioptera), and bigeye (Priacanthus tayenus). The four fish groups are important demersal fisheries in Indonesia, especially those landed in PANTURA.
