Abstract

This study aims to confirm the species identity of Charybdis affinis from the coastal waters of Tuban, Indonesia, using integrated morphological and molecular approaches. Specimens were examined based on morphological characteristics including carapace shape, anterolateral teeth arrangement, cheliped spination, and dorsal setation. Morphometric analysis showed carapace width ranging from 4.09–4.40 cm and length from 2.68–2.99 cm. Molecular identification was conducted using the mitochondrial cytochrome c oxidase subunit I (COI) gene. PCR amplification produced a 638 bp DNA fragment. BLAST analysis revealed 99.06% sequence identity with Charybdis affinis in GenBank with 100% query coverage, and the obtained sequence has been deposited in GenBank under accession number PV699569.1. Phylogenetic reconstruction using the Neighbor-Joining method showed that the samples clustered within the C. affinis clade and were clearly separated from closely related species. These findings confirm the first molecular record of C. affinis in Indonesian waters and demonstrate strong agreement between morphological and genetic characteristics. This study provides essential baseline information for biodiversity assessment and sustainable management of portunid crab resources.

Abstract

Tingkat pemanfaatan (E) udang Penaeus merguiensis di perairan pantai Laut Arafura Merauke Provinsi Papua Selatan dalam kategori over-fishing (E=0,76/tahun untuk jantan dan betina E= 0,59/tahun). Mortalitas karena penangkapan (F) lebih besar dari mortalitas alami (M), menunjukan tekanan penangkapan tinggi.  Tujuan penelitian menganalisis penentuan ukuran mata jaring untuk keberlanjutan penangkapan udang P. merguiensis di perairan pantai Laut Arafura Merauke Provinsi Papua Selatan. Metode survei digunakan dalam penelitian, dengan teknik pengambilan sampel: sistimatik sampling.  Waktu pengumpulan data: Agustus 2022 - Juli 2023 pada tiga stasiun penelitian.  Analisis data utamanya penentuan ukuran mata jaring. Ukuran mata jaring untuk keberlanjutan udang P. merguiensis di stasiun A Distrik Naukenjerai = 50,80 - 98,21 mm; stasiun B Distrik Merauke = 42,68 mm; dan stasiun C Distrik Semangga = 50,05 mm. Penentuan ukuran mata jaring ini telah mempertimbangkan ukuran pertama matang gonad udang P. merguiensis pada ketiga stasiun penelitian: A Distrik Naukenjerai = 42,20 mmCL, B Distrik Merauke = 40,20 mmCL, dan C = 42,00 mmCL. Pengaturan ini dimaksudkan agar udang yang tertangkap secara ekonomi menguntungkan, dan kelestarian sumber daya udang dapat dijaga. Hasil penelitian dapat dijadikan pertimbangan kebijakan penentuan ukuran mata jaring trammel net dan pukat tarik dalam penangkapan udang secara berkelanjutan.
