Title

Morphological characteristics and genetic diversity of fish Moolgarda cunnesius (Valenciennes, 1836) in Tam Giang Lagoon, Vietnam

Abstract

Moolgarda cunnesius, belongs to the Mugilidae family, is an important fish species in view of its immense contribution to the need of Vietnam in terms of nutrition, economic growth and development. The results of morphometric and genetic analysis of M. cunnesius in this study contributed the documents for identifications and the genetic diversity, which are the basic for further researches about M. cunnesius in breeding, species conservation and management at the Tam Giang Cau Hai Wetland Reserve. Research results showed that this species distributed in the North has a size ranging from 101.7 to 160.7 mm, with an average of 137 mm, corresponding to a weight of 10.6 - 35.6 g, with an average of 25.2 g, the fish distributed in the South has a size ranging from 112.4 - 172.7 mm with an average of 144 mm, corresponding to a weight of 10.6 - 35.6 g, an average of 28.3 g. Using CO1 gene DNA barcoding to study the genetic diversity of M.cunnesiusin two regions of the North and the South of Tam Giang lagoon, the samples were amplified and sequenced the CO1 gene region. Amplified and sequenced 10 samples of CO1 gene of M. cunnesius sample in Tam Giang lagoon with the size of 650 bp. The average ratio of four types of nucleotides is A: 23.38%; T: 32.62%; G:18.15%; C: 25.85%. The rate of difference in CO1 sequences of the 2 samples is low compared to previous studies. The similarity coefficient of M. cunnesius in the two areas of Tam Giang lagoon is very high (0.9953).
