Abstract

Parrotfish capture fisheries production in the Seribu Islands Waters is quite high. This study aims to determine several aspects related to parrotfish (S. rivulatus) population dynamics in the Seribu Islands Waters. This research was conducted for 12 months, starting from January to December 2022. The results of the analysis of the growth coefficient of male parrotfish are K=0.54 year-1, while females' growth coefficient is K=0.75 year-1. Growth parameters from the von Bertalanffy equation, for males Lt=312.4[1-exp-0.54(t-(-0.158))] and females Lt=280.4[1-exp-0.75(t-(0.12))]. Recruitment occurred twice during the 2022 period, with peak recruitment of males occurring in April and August and females in May and September. Completion mortality (F) was higher than natural mortality (M). Male parrotfish F=1.06M=0.63 and females F=4M=0.80. Mean first-capture size (Lc) for male fish Lc=174 mm and females 147 mm.Keywords:Over-exploitationParrotfishSeribu Islands

Abstract

Raja Ampat conservation area is divided into three zones: the core zone, the tourism zone, and the open zone. This region is crucial for sustainable fisheries and environmental management, yet it is under significant anthropogenic pressure. Accurate species detection is essential for inventory and diversity surveys, and environmental DNA (eDNA) methods have been shown to be more effective than conventional techniques. This study aimed to evaluate whether V9 primers could detect multispecies invertebrate compositions, assess community structure and contributions within each zone, and identify significant differences in invertebrate diversity among the zones. A total of 66 eDNA samples were collected from water and sediment columns across the three zones. Samples were extracted using the NucleoSpin„¢ kit (Macherey-Nagel) protocol, amplified with universal eukaryote primers targeting the 18S gene, and sequenced using Illumina MiSeq. Taxonomic analysis was performed using QIIME2 software and the SILVA database. The study identified 19 invertebrate species. The Shannon-Wiener (H') and Simpson (D) indices revealed greater species diversity in the core zone compared to the tourism and open zones. However, the Kruskal-Wallis test indicated no significant differences in species diversity across the zones. SIMPER analysis demonstrated a high percent contribution of species in each zone. This study highlights the effectiveness of eDNA methods for biodiversity assessment and offers valuable insights into invertebrate community structures within the Raja Ampat conservation area.
