Abstract

Information related to osteology plays a vital role in support ecomorphology and phylogenetic relationship analysis in fish. This study aimed to describe the comparative morphology of the vertebral column between Tor tambroides (Bleeker, 1854) and Tor tambra (Valenciennes 1842). Samples of Tor tambroides and Tor tambra were obtained from fish traders in the Tangse River area of Pidie Regency and Sampoinet River area, Aceh Jaya Regency, Aceh Province. Vertebral column preparation consists of five steps: muscles and scales separation, immersion in a formaldehyde solution, drying, morphometric measurements, photographing and image editing, and identification of terminology. The results showed that there are morphological differences between Tor tambroides and Tor tambra vertebral column, particularly in the axial vertebrae, posterior vertebrae caudales, and urostylus regions. The pleural costae of Tor tambroides have a posterior curve with the left and right sides interlocking. The lateral Tor tambroides process tends to curve posteriorly, while the Tor tambra tends to round up parallel to the dorsal costae. Tor tambroides tend to have stronger ligaments marked by the absence of a foramen between the hypural. Morphometrically, Tor tambroides tend to have higher centrum ratios (length, width, and height), neural spine, haemalis spine, and costae compared to Tor tambra. The significant difference in morphometric results in observed the axial vertebrae and the posterior vertebrae caudales region. Further research related to the correlation of vertebral column morphology with the environmental condition of these fish is still necessary. Abstrak Kajian osteologi memiliki peran penting dalam upaya analisis ekomorfologi dan hubungan filogenetik antarjenis ikan. Penelitian ini bertujuan untuk mendeskrispsikan perbedaan morfologi tulang belakang Tor tambroides (Bleeker, 1854) dan Tor tambra (Valenciennes 1842). Contoh ikan Tor tambroides dan Tor tambra dikoleksi dari hasil tangkapan nelayan di wilayah Sungai Tangse Kabupaten Pidie dan wilayah Sungai Sampoinet, Kabupaten Aceh Jaya, Provinsi Aceh. Tahapan preparasi tulang belakang terdiri atas lima tahapan yaitu pemisahan otot dan sisik, perendaman dalam larutan formalin, penjemuran, pengukuran morfometrik, pemotretan dan penyuntingan gambar, serta identifikasi terminologi. Hasil penelitian ini menunjukkkan bahwa terdapat perbedaan morfologi tulang belakang antara Tor tambroides dan Tor tambra terutama pada bagian axial vertebrae, posterior vertebrae caudales dan urostylus. Tulang pleura costae Tor tambroides memiliki bentuk melengkung ke arah posterior dengan bagian kiri dan kanan saling bertautan. Processus lateralis Tor tambroides cenderung melengkung ke arah posterior, sedangkan pada Tor tambra cenderung membulat sejajar dengan dorsal costae. Tor tambroides cenderung memiliki ligamen yang lebih kokoh ditandai dengan tidak adanya foramen diantara os hypural. Secara morfometrik tulang belakang, Tor tambroides cenderung memiliki nilai nisbah centrum (panjang, lebar dan tinggi), spina neuralis, spina haemalis dan costae yang lebih tinggi dibandingkan dengan Tor tambra. Disparitas hasil pengukuran antara kedua jenis ikan terlihat cukup kentara pada bagian axial vertebrae dan bagian posterior vertebrae caudales. Penelitian lanjutan terkait korelasi morfologi tulang belakang dengan kondisi perairan kedua jenis ikan masih perlu dilakukan.

Abstract

Penelitian ini dilaksanakan dengan tujuan mendeskripsikan secara utuh perbedaaan anatomi morfologi tulang rangka ikan Keureling, Tor tambroides dan Tor tambra. pengamatan dianalisis secara deskriptif, sampel dikoleksi dari kawasan perairan desa Ie Jeureungeh, Kabupaten Aceh Jaya, Provinsi Aceh. Pembuatan preparat tulang rangka ikan dilakukan secara fisik dan kimiawi. Tahapan fisik diawali Sisik ikan dihilangkan dengan menggunakan pisau atau pinset otot di bedah, pembedahan otot ikan dilakukan sampai tulang-tulang pada ikan nampak baik, Tahapan kimiawi diawali dengan merendam preparat tulang rangka kedalam formalin 10% selama tujuh hari. Selanjutnya dilakukan perendaman dalam larutan etanol 100% selama 24 jam

Abstract

The whiteleg shrimp (Litopenaeus vannamei) is a prominent species in global aquaculture due to its resilience to environmental fluctuations and high growth potential. The success of the larval phase is critically determined by feed quality and the stability of the culture environment. This study comparatively evaluated the efficacy of various feed types on the performance of Litopenaeus vannamei postlarvae. A comparison was made between live, frozen, and preserved natural feed (Artemia sp.) and formulated pellet feed in terms of growth, survival rate, and Vibrio bacteria abundance. The results highlighted that frozen Artemia sp. (P2) was significantly superior to other treatments. Postlarvae fed frozen Artemia sp. exhibited the highest growth (length and absolute weight) and survival rate, reaching 78.67%, significantly surpassing the pellet-fed group (K1) with a survival rate of only 60.67%. Furthermore, the Vibrio bacteria abundance in the frozen Artemia sp. fed group was also relatively low compared to the pellet-fed group (13.33 CFU mL⁻¹). Although live and preserved Artemia sp. yielded better results than pellet feed, frozen Artemia sp. remains the most effective feed choice for optimizing early-stage L. vannamei aquaculture.

Abstract

Bireuen Regency, located on the eastern coast of Aceh, is rich in natural resources, particularly in marine fisheries. Among these, mantis shrimp are a notable resource, though their population dynamics remain undocumented. Currently, mantis shrimp are considered bycatch by local fishermen, with most being discarded. To address this gap, this study aimed to identify and analyze the morphology and composition of mantis shrimp in the waters of Bireuen Regency. The research was conducted from October 2024 in Gandapura District, employing purposive random sampling at three designated sites. The species identified was Harpiosquilla raphidea. Morphological measurements revealed six body segments: head length (PK), head width (LK), body length (PB), body width (LB), tail length (PE), and tail width (LE). Results indicated that mantis shrimp constituted 50% of the catch, followed by tiger shrimp (25%) and kelong shrimp (25%). The length-weight relationship of mantis shrimp showed a b-value of <3, signifying negative allometry, where growth in length outpaces growth in weight. These findings provide baseline data for further studies on mantis shrimp populations and their potential utilization in sustainable fisheries.

Abstract

North Aceh and Lhokseumawe Regency are promising regions in the marine and fisheries industry, encompassing both big pelagic and small pelagic fish. The industrial zone in North Aceh and Lhokseumawe Regency is characterized by significant activity, where activity pertains to both industrial operations in the region and activities in coastal zones. The current industries include PT Pupuk Iskandar Muda, PT ASEAN Aceh Fertilizer, PT Kertas Kraft Aceh, and PT Arun Natural Gas Liquefaction. Identifying microplastics in economically important fish in industrial area waters is necessary to determine whether the fish contain microplastics. The aim of this research is to determine the microplastic content in three economically fish, namely trevally (Caranx ignobilis), grouper (Epinephelus fuscoguttatus), and mackerel (Rastrelliger sp.). The research was carried out in 2024. Data and samples were collected using a survey method taken directly in the field. The data collection points during the research were at four locations around the industrial area, namely PT Pupuk Iskandar Muda (station 1), PT ASEAN Aceh Fertilizer (station 2), PT Kertas Kraft Aceh (station 3), PT Arun Natural Gas Liquefaction (station 4) in the waters of North Aceh and Lhokseumawe Regency. Analysis of microplastic content was carried out at the Oceanography Laboratory, Faculty of Agriculture, Malikussaleh University. Based on research results, the types of microplastics found in the digestive organs of trevally, grouper and mackerel are fiber, film, fragments, granules, pellets, and foam. Frequency value of microplastics found at the research location from the four stations, where the most dominant found was the foam type (35.96%) on trevally, fiber type (22.59%) on grouper, and fiber type (35.19%) on mackerel.
