“…Karakteristik perairan sekitaran pulau Weh di dominasi oleh ekosistem terumbu karang dengan kondisi sedang hingga sehat (Hastuty dan Hadriyanto, 2014). Penelitian sebelumnya oleh Zulfahmi et al (2022), mengungkap sebanyak 5 jenis ikan genus scarus yang didaratkan di Kota Sabang yaitu Scarus tricolor, Scarus quoyi, Scarus rubroviolaceus, Scarus niger, dan Scarus quoyi. Scarus quoyi, Scarus Rubroviolaceus, dan Scarus niger merupakan jenis scarus yang dominan tertangkap dan banyak diperjualbelikan.…”

Scarus fish play an important ecological role in supporting the health of coral reefs. Unfortunately, studies related to morphometric variations, growth patterns and condition factors of scarus fish are still unexplored. Hence, this research aimed to describe morphometric variations, growth patterns and condition factors of scarus fish (Scarus quoyi, Scarus rubroviolaceus and Scarus niger) collected from Pulau Weh water, Aceh. As many as 50 fish for each species were obtained through fishermen's catches. The main parameters investigated include morphometric comparisons, length and weight distribution, growth patterns and condition factors. The number of morphometric characters measured was 12 characters. Morphometric comparisons and condition factors between fish species were analyzed using one-way ANOVA followed by the Least Significant Difference Test (LSD) and discriminant function test. Meanwhile, comparative growth patterns were analyzed descriptively. The research results show that dorsal finbase length, pectoral fin length, and caudal peduncle depth were key characters in distinguishing the three species of scarus fish. A comparison of morphometric characters between Scarus quoyi and Scarus rubroviolaceus showed a 63.6% different character. Meanwhile, both Scarus rubroviolaceus and Scarus niger, and Scarus quoyi and Scarus niger showed a 54.5% different character. All scarus fish in this study had a negative allometric growth pattern (b<3) with condition factor values ranging from 1.008 to 1.020. Efforts to develop fishing gear selectivity and further research related to reproductive biology aspects of the scarus fish are essential to obtain comprehensive information and support sustainability programs. Ikan genus scarus memiliki peran ekologis penting memelihara kesehatan terumbu karang. Sayangnya, kajian terkait variasi morfometrik, pola pertumbuhan dan faktor kondisi ikan genus scarus masih minim diungkap. Penelitian ini bertujuan untuk menganalisis variasi morfometrik, pola pertumbuhan serta faktor kondisi ikan genus scarus (Scarus quoyi, Scarus rubroviolaceus dan Scarus niger) yang dikoleksi dari perairan Pulau Weh, Aceh. Jumlah sampel ikan yang dianalisis untuk masing-masing spesies berjumlah 50 ekor yang diperoleh melalui hasil tangkapan nelayan. Parameter utama yang dianalisis meliputi komparasi morfometrik, distribusi selang kelas panjang dan bobot, pola pertumbuhan serta faktor kondisi. Jumlah karakter morfometrik yang diukur sebanyak 12 karakter. Komparasi morfometrik dan faktor kondisi antar jenis ikan dianalisis menggunakan ANOVA satu arah diikuti dengan Uji Beda Nyata terkecil (BNT) dan uji fungsi diskriminan. Sementara itu, komparasi pola pertumbuhan dianalisis secara deskriptif. Hasil penelitian menunjukan bahwa panjang sirip dorsal, panjang sirip pektoral, dan tinggi batang ekor merupakan karakter kunci yang dapat membedakan ketiga spesies ikan genus scarus. Komparasi karakter morfometrik antara Scarus quoyi dengan Scarus rubroviolaceus menunjukkan persentase perbedaan karakter sebesar 63,6%. Sementara itu, baik antara Scarus rubroviolaceus dan Scarus niger maupun Scarus quoyi dengan Scarus niger sama- sama menunjukkan persentase perbedaan karakter sebesar 54,5%. Ketiga ikan scarus memiliki pola pertumbuhan alometrik negatif (b<3) dengan nilai faktor kondisi berkisar antara 1.008 hingga1.020. Upaya pengembangan selektivitas alat tangkap dan penelitian lanjutan terkait aspek biologi reproduksi ikan genus scarus penting dilakukan untuk mendapatkan informasi yang komprehensif dalam upaya mendukung kelestarian dan pemanfaatan yang berkelanjutan.

“…In different areas (i.e. Lhoknga and Lhok Mata Ie Beaches) 25 fish species which are members of eight orders, 11 families, and 19 genera were recorded from 51 fish samples (Nur et al 2019); 71 species were identified in Pusong Bay, Lhokseumawe belonging to 54 genus, 37 families and 15 orders (Damora et al 2020); 50 species were identified in the Weh Island, Sabang belonging to 24 families and eight orders (Zulfahmi et al 2022). The morphological approach is the most widely used method in many regions in Indonesia, including in Banda Aceh.…”

The enormous potential of marine resources possessed by Banda Aceh Province is expected to be utilised optimally. Accuracy in marine fish resource identification is a critical requirement to support their utilisation and preservation in Banda Aceh Province. In this study, a molecular identification approach was carried out in addition to conducting a morphological identification, commonly used by several scientists. The results were 47 COI sequences generated representing 33 genera, 19 families, and five orders. From the resulting COI partial sequences, there is one potential haplotype from the Scombridae family (Auxis thazard), two potential haplotypes from the Carangidae family (Elagatis bipinnulata and Decapterus macarellus), and two potential haplotypes from the Serranidae family (Variola albimarginata and Cephalopholis sonnerati). This study is essential for fisheries biological studies and other fisheries studies to support the sustainable utilisation of marine fisheries potential in Banda Aceh.
