| Abstract | ||||
| Utilizing measured fisheries is an effective method for ensuring the long-term viability of the tiger prawn (Penaeus monodon) populations in the Arafura Sea, particularly following the post-moratorium from 2015 to 2021. Biological factors are a type of information that is considered in the process of making decisions. The objective of this study was to ascertain the pattern of the length-weight relationship, condition factor, sex ratio, gonad maturity stage, first length caught (L50), and first length maturity. The investigation was done in the Arafura Sea from February 2023 to January 2024. The acquired data were examined utilizing Excel software. The findings indicated that the captured tiger prawn (P. monodon) varied in size, ranging from 30,2 to 99,8 mmCL. The average length was 62,03 ± 11,70 mmCL, with a mode of 60 mmCL for carapace length. The growth exhibited a negative allometry. The condition factor (K) varied between 0,139 and 3,293, with an average of 1,172 ± 0,611. The sex ratio under balanced conditions was 1,01 males : 1 female. The majority of the catch consists of prawn with fully developed gonads (phase III, IV, and V). The mean length of the tiger prawn captured (Lc) was 61,98 ± 7,87 mmCL, which was larger than the mean length of mature gonads (Lm) at 60,03 ± 7,75 mmCL. The current state of the tiger prawn fishing after the ban is highly favorable and requires careful maintenance and regulated management, including controlling the amount of fishing gear, determining the fishing season, and managing the fishing area, in order to ensure its sustainability. | ||||
