The objective of the present study was to inventory the coral fish fingerling in Lhoknga and Lhok Mata Ie Beaches, Aceh Besar District, Aceh Province, Indonesia. The study was conducted from February to March 2019 in two locations, namely;Lhoknga Beach and Lhok Mata Ie Beach in Aceh Besar District, Aceh Province, Indonesia. The fish sample was caught using a handline hook and casting net. A total of 51 fish were sampled during the study, and it belongs to 8 orders, 11 families, 19 genera, and 25 species. The Labriformes was predominant with six genus and eight species followed by Scorpaeniformes (four species), Perciformes and Blenniiformes, four species respectively. Carangiformes, Mugiliformes, and Gobiiformes with two species, respectively and Anguilliformes with one species.In addition, Epinephelus was the predominant genus with four species.

Skipjack tuna (Katsuwonus pelamis) is a pelagic fish species that have important economic value in the northern and western waters of Aceh. Skipjack tuna is one of the dominant catch fish landed at the Fishing Port of Kutaraja, Banda Aceh. The dynamics population of skipjack tuna in the northern and western waters of Aceh need to be done to get information on the status of skipjack tuna in ocean. This research aims to determine the dynamic parameters of the population of skipjack tuna based on the growth parameters, length and weight relationship, length distribution, length at the first capture, mortality, and exploitation rate. The data collection was conducted in February to March 2020, located at the Fishing Port of Kutaraja, Lampulo, Banda Aceh. A total of 166 sample, were measured with stratified random sampling method. The FAO-ICLARM Stock Assessment Tools (FiSAT) program was used by analyze growth parameter, mortality parameters, and exploitation rate. The results showed that has a negative allometric growth pattern, with a length of fork length (FL) ranging from 25-51 cm. The length of first capture was 38,2 cm. The asymptotic length (L∞) of skipjack tuna was 84,78 cm with K value of 0.22/year and. The estimated natural mortality (M), fishing mortality (F), and total mortality (Z) were 0,5/year, 1.55/year, and 2.99/year respectively. The exploitation rate (E) of skipjack tuna was 0.83/year that indicated skipjack tuna in the Northern and Western waters of Aceh over-exploited.

Teluk Lamteng memiliki potensi ekosistem lamun yang sangat besar. Potensi lamun yang besar ini turut menyokong kelimpahan sumberdaya perikanan di daerah tersebut. Penelitian ini bertujuan untuk mengetahui keragaman lamun. Penelitian ini dilaksanakan pada bulan Desember 2018, dimana penentuan stasiun pengamatan menggunakan metode purposive sampling yaitu berdasarkan observasi mencakup area yang terdapat dermaga, baik dermaga kecil maupun dermaga besar. Analisis data yang digunakan yaitu persentase tutupan lamun (C), kerapatan jenis lamun (Di), keanekaragaman lamun (H’), serta indikator keberadaan dugong yaitu dengan melakukan survei feeding trail yang ditinggalkan oleh dugong dan menduga preferensi lamun yang menjadi favorit dugong sebagai makanannya. Hasil penelitian menunjukkan bahwa komposisi jenis lamun yang ditemukan di perairan Teluk Lamteng terdiri dari tiga spesies yaitu Cymodocea serrulata, Halodule pinifolia dan Halophila ovalis. Penutupan lamun tertinggi oleh spesies H. pinifolia adalah 67,84%, selanjutnya diikuti C. serrulata sebesar 44,79% dan paling rendah yaitu spesies H. ovalis dengan angka 2,21%. Secara keseluruhan stasiun, spesies H. pinifolia memiliki nilai kerapatan yang lebih tinggi dibandingkan dengan kedua spesies lamun lainnya, yaitu antara 55-316 ind/m2. Keanekaragaman lamun tergolong rendah dengan nilai berkisar antara 0-0,9. Ketiga spesies lamun yang ditemukan merupakan sumber pakan bagi D. dugon yang termasuk dalam kategori preferensi lamun kesukaannya.

The objective of the present study was to analyze the morphometric character of the three species within Gourami group, namely Trichopsis vittata, Trichopodus pectoralis and Trichopodus trichopterus. The T. vittata samples were collected from Aceh Tamiang District, the T. pectoralis were collected from Aceh Besar District, and the T. trichopterus were collected from Aceh Jaya District, Indonesia. A total 150 individual of fish samples (50 individual of every species) were measured for traditional morphometric characters. The results of univariate (ANOVA) analysis showed that all morphometric characters measured in three fish species were significantly different (P <0.05). Multivariate (Discriminant function analysis, DFA) analysis showed that T. pectoralis and T. trichopterus have more similar morphological characteristics, whereas T. vittata was discriminated distinctly. These results confirm that the level of relationship between T. trichopterus and T. pectoralis is closer than T. vittata.
