چکیده
Mahseer (genus Tor dan Neolissochilus) adalah ikan dari famili Cyprinidae yang tersebar luas di Asia Selatan hingga Indonesia bagian barat. Saat ini keberadaan tersebut alam terancam akibat degradasi lingkungan, salah satunya Jawa Timur, Indonesia. Berkurangnya jenis mengakibatkan kepunahan spesies masa akan datang terbatasnya peran pada ekosistem karena kehilangan keragaman genetik. Keragaman genetik dapat diketahui dengan adanya karakteristik morfologi untuk mengetahui status suatu ikan. Tujuan penelitian mengidentifikasi keanekaragaman mahseer berdasarkan karakter beberapa lokasi sungai Timur. Sampel diperoleh Kabupaten Pasuruan (DAS Banyubiru Umbulan), Tulungagung Song), Karanganyar Senatah). Identifikasi dilakukan panduan identifikasi. Karakteristik diamati morfologi, meristik, fitur tambahan (matriks pola warna). Hasil kajian menunjukkan bahwa terdapat 2 yaitu tambra tambroides.

The Species Dilemma of Northeast Indian Mahseer (Actinopterygii: Cyprinidae): DNA Barcoding in Clarifying the Riddle
BACKGROUND The taxonomic validity of Northeast Indian endemic Mahseer species, Tor progeneius and Neolissochilus hexastichus, has been argued repeatedly. This is mainly due to disagreements in recognizing the species based on morphological characters. Consequently, both the species have been concealed for many decades. DNA barcoding has become a promising and an independent technique for accura...
متن کاملGenetic Structure and Preliminary Findings of Cryptic Diversity of the Malaysian Mahseer (Tor tambroides Valenciennes: Cyprinidae) Inferred from Mitochondrial DNA and Microsatellite Analyses
This study examines the population genetic structure of Tor tambroides, an important freshwater fish species in Malaysia, using fifteen polymorphic microsatellite loci and sequencing of 464 base pairs of the mitochondrial cytochrome c oxidase I (COI) gene. A total of 152 mahseer samples were collected from eight populations throughout the Malaysia river system. Microsatellites results found hig...
