Abstract

The research on morphometry variation of Papilio polytes L. (Lepidoptera: Papilionidae) was conducted on December 2011 until April 2012 in West Sumatera (Padang Panjang, Padang and Marak Island). Papilio polytes were directly collected from the field and morphological measurement was conducted in Genetic Laboratory, Biology Department, Andalas University Padang. The morphological characters were significantly different among males. Those characters were forewings length, hindwings length, antenna length, eyes distance, foreleg length and wing venations. While differentiation also found among females. Those characters were forewings length, hindwings width, foreleg length and wing venations. There was a high of female morphological differentiation between Padang - Marak island and Padang Panjang – Marak Island. Male individual had low variation between that places.Keywords: variation, morphometry, Papilio polytes, West Sumatra

Abstract

A study about cephalometry variations of three ethnic groups living in West Sumatra was conducted from May until August 2012. This study used survey method and purposive sampling technique. The measurements of cephalometry were taken from total of 150 individu samples with frontal photos from head-face. The result showed significant variations on head length, head width, upper facial height, bizygomatic breadth, eyes width, distance of endocathion, nose length, nose width, chin height, minimum frontal height and distance of stomion to menton. Based on statistic analysis, Nias, Minang and Mentawai ethnics showed different cephalic, facial, frontoparietal and nasalis type. Phenogram by UPGMA of three ethnic groups showed close relationship between Nias and Mentawai.Keywords : variation, cephalometry, ethnics, West Sumatra.

Abstract

The morphological analysis of Puntius binotatus Valenciennes 1842 (Pisces: Cyprinidae) collected from several locations in West Sumatra has been conducted from April to June 2012. Several morphological characters were measured and analyzed using principal component analysis (PCA) and UPGMA. This study found significant morphological variations of the standard length (SL), head length (HL), least depth of caudal peduncle (HCPD), length of caudal peduncle (LCPD), eye diameter (ED), caudal fin length (CFL), caudal fin length up (CFL up), caudal fin length bottom (CFL bottom), length of maxillary barbels (LMB) and length of snout barbels (LSB). Those variations were more likely influenced by elevations and western-eastern side of Barisan Mountain in Sumatra.Keywords: Barisan Mountain, cyprinidae, morphological characters, P. binotatus

Abstract

Chromosomal characteristics of catfish Hemibagrus lacustrinus, known as Baung fish, a new species of bagrid catfish from the upriver stream of Batang Sianok, West Sumatra, that recently described by Ng and Kottelat, 2013 was examined from the gills of 5 healthy specimens using general squash method. The result showed that diploid chromosome number of this species was 2n=56. Thekaryotype consisted of 28 metacentric (m), 10 submetacentric (sm), 8 subtelocentric (st) and 10 acrocentric (a) chromosomes. The chromosome formula can be represented as 2n= 28m+ 10sm+ 8st+ 10a. The largest chromosome in this species is a pair of submetacentric chromosomes and the smallest pair is acrocentric chromosomes. The present study is the first report on the karyology of this particular species and helping to support the karyotype data of the genus Hemibagrus. This study will also open for several future studies to explore this species.

Abstract

Fekunditas, diameter telur, dan kebiasaan makanan ikan merupakan bagian dari aspek reproduksi ikan yang sangat penting diketahui. Informasi ini dapat digunakan untuk memprediksi rekruitmen dan pemulihan stok ikan bujuk dalam rangka domestikasi dan budidaya. Penelitian dilakukan dari bulan Januari-November 2010 pada habitat berbeda yaitu di Danau Singkarak-Sumatera Barat, perairan rawa banjiran Pematang Lindung Kabupaten Tanjung Jabung Timur-Jambi, dan perairan Mentulik Kabupaten Kampar-Riau. Jumlah sampel yang diamati 30 gonad ikan betina TKG III dan IV masing-masing lokasi penelitian. Fekunditas total ikan bujuk dari Danau Singkarak 1.996±568 butir dengan diameter telur 1,35±0,09 mm; rawa banjiran Pematang Lindung-Jambi 2.196±866 butir dengan diameter telur 1,53±0,11 mm; dan rawa banjiran Mentulik Kampar-Riau 2.539±716 butir dengan diameter telur 1,70±0,14 mm. Makanan utama ikan bujuk adalah ikan (70,78%-89,01%) dan makanan pelengkap udang (5,81%-16,13%), katak (1,77%-4,25%), dan makanan tambahan serangga air (3,98%-9,80%). Berdasarkan jenis makanan tersebut, maka ikan bujuk termasuk kelompok ikan karnivora murni yang bersifat predator.

Abstract

Cyclocheilichthys apogon (Beardless Barb fish) and Cyclocheilichthys armatus (Hihgfin Barb fish) in West Sumatra is known by the local name Turiak and Catua fish, respectively, are economically important species. Reducing populations and limited biological information about these fishes make their genetic diversity and phylogenetic relationships crucial. The genetic variation was investigated by analyzing the sequencing of a part of mitochondrial DNA Cytochrome b (Cyt b) and Cytochrome oxidase-I (COI) genes of 23 individuals collected from West Sumatra populations. Phylogenetic analysis revealed the monophyletic lineage of the Cyclocheilichthys group and supported Anematichthys as the synonym of Cyclocheilichthys. C. armatus was closely related to C. janthochir and separated from C. apogon with sequences divergence were 12.7-14.0% (Cyt b) and 9.4%-10.0% (COI). C. apogon and C. armatus have low haplotype diversity and genetic diversity, respectively. Genetic diversity within and among populations with sequences divergence was 0.0-0.8% (Cyt b) and 0.0%-0.7% (COI), respectively. The low-level diversity may signify a possibility of gene flow within and among populations. The current data suggests all populations as a single stock unit. Present genetic information is important to establishing effective population management, conservation, and breeding strategies for Turiak and Catua fish.
