Morphology of appendicular skeleton of the Thai mahseer’s Tor tambroides (Bleeker, 1854)

Abstract

This study aims to describe the appendicular skeleton morphology (ossa appendicularis) of Thai mahseer’s (Tor tambroides Bleeker, 1854). The samples were obtained from fish traders in the Tangse River area of Pidie district, fish weight about 5 kg and length of 65 cm. The axial skeleton preparations conducted at the Laboratory of Mathematics and Natural Sciences, Almuslim University, Bireuen district. The skeleton terminology identification was done at Integrated Biology Laboratory, Biology Department, Faculty of Science and Technology, Ar-Raniry Islamic State University. The preparation of Thai mahseer’s axial skeleton was done by physically and chemically processed. Axial skeleton was arranged into a single piece to analyze every part of it. Documentation every part of axial skeleton was using Canon EOS 700D camera and processed by Adobe Photoshop CS3. The structure of fish constituent was named based on some published papers. The results showed that appendicular skeleton of Thai mahseer belonging to a pair of pectoral fin (pinna pectoralis), a pair of abdominal fins (pinna pelvis), the dorsal fin (pinna dorsalis), anal fin (pinna analis) and the caudal fin (pinna caudalis). Thai mahseer has similar morphological characters of appendicular skeleton compared to its family (Cyprinidae) but has some difference when compared to other families (Osphronemidae, Zaproridae, dan Tetraodontidae).AbstrakPenelitian ini bertujuan untuk mendeskripsikan morfologi tulang anggota gerak (ossa appendicularis) ikan keureling (Tor tambroides Bleeker, 1854). Contoh ikan diperoleh dari pedagang ikan di wilayah sungai Tangse Kabupaten Pidie dengan bobot 5 kg dan panjang 65 cm. Tahapan pembuatan preparat tulang dilakukan di Laboratorium Matematika dan Ilmu Pengetahuan Alam, Universitas Almuslim Kabupaten Bireuen, sedangkan identifikasi terminologi tulang anggota gerak ikan dilakukan di Laboratorium Terpadu Biologi, Program studi Biologi, Fakultas Sains dan Teknologi, Univer-sitas Islam Negeri Ar-Raniry. Pembuatan tulang anggota gerak dilakukan secara fisik dan kimiawi. Pemotretan setiap bagian tulang dilakukan dengan menggunakan kamera Canon EOS 700D dan diolah dengan menggunakan Adobe Photoshop CS3. Penamaan setiap bagian tulang anggota gerak dilakukan dengan cara membandingkan kemiripan bentuk dan letak setiap bagian tulang anggota gerak ikan yang telah diteliti sebelumnya, baik dari famili yang sama maupun dari famili yang berbeda. Hasil penelitian menunjukkan bahwa tulang anggota gerak (ossa appendicularis) ikan keureling terdiri atas sepasang sirip dada (pinna pectoralis), sepasang sirip perut (pinna pelvis), sirip punggung (pinna dorsalis), sirip anal (pinna analis), dan sirip ekor (pinna caudalis). Karakteristik sirip ikan keureling relatif sama pada famili sejenis (Cyprinidae), namun terdapat perbedaan apabila dibandingkan dengan ikan dari famili lainnya (Osphronemidae, Zaproridae, dan Tetraodontidae).

A Current Update on the Distribution, Morphological Features, and Genetic Identity of the Southeast Asian Mahseers, Tor Species

“…The river system areas inhibited by T. douronensis are Balong Dalem, Darma Loka, Cigugur, Cibulan, and Bale Kambang [ 81 ]. In Kalimantan of Borneo, T. tambroides have been reported in riverine systems of Muller Mountain in Central Kalimantan [ 55 , 56 ]. In addition, T. tambroides and T. tambra have been reported in the Mendalam river system, Betung Kerihun National Park, West Kalimantan.…”

The Path Forward: Conservation of Climate Change-Affected Breeding Habitat of Red-crowned Cranes near Zhalong Reserve, China

“…to devise policies on management and conservation of mahseer but is still scarce. Previous studies have reported progress with respect to biological information on mahseer including taxonomy (Zulfahmi et al, 2018), growth performance (Muchlisin et al, 2016), morphology (Akmal et al, 2018) and genetics (Arifin et al, 2015). However, there is a lack of information on aspects such as sex ratio, condition factor, fecundity and reproductive potential.…”

A Comparison of the Differences in Some Cranial Bones of Two Species Common Carp Cyprinus Carpio and the Common Tilapia Coptodon Zillii

“…Studies concerning fish bones are still rare and scarce compared to the study of the bones of some mammals and birds (Leprevost and Sire, 2014). Despite the availability of a few previous studies on the skeleton and the bones of the type Tor tambroides (Akmal et al, 2020), detailed studies of the skull bones of this species were not studied, and detailed studies on the bones of the species Coptodon zillii and Cyprinus carpio and the study of the skull and cranial bones of these two species were not available in detail (Akmal et al 2018a;2018b;Zulfahmi et al, 2018); therefore, this study attempts to identify some of the bones of the skulls of these two types and make a comparison between them in terms of the shape as the two families are characterized by differences within their families and sexes, while also aiming to identify some of the characteristics of these bones for these two types.…”
