Population dynamics of mantis shrimp (Miyakea Nepa Fabricius, 1781) in Siwa, Bone Bay, South Sulawesi, Indonesia

Abstract

Abstract Miyakea nepa is a mantis shrimp commonly found in the coastal waters of Bone Bay, Indonesia. This study aimed to determine mantis shrimp population dynamics including age groups, growth, mortality, exploitation rate, and relative yield per recruit. The study was conducted in the waters around Siwa in Bone Bay, South Sulawesi from June to July 2019. The age groups, natural mortality, total mortality, fishing mortality, exploitation level, and yield per recruit were calculated and analyzed using equations and methods contained in the FAO-ICLARM Fish stock Assessment Tools II (Fisat II) program. The results imply rapid growth in the mantis shrimp Miyakea nepa (Latreille,1828) and indicate that the population studied has been over-exploited.
