Sequencing and analysis of the mitochondrial genome of (Bloch, 1793) (Perciformes: Sciaenidae).

Donkey croaker, (Bloch, 1793) is a commercially important croaker in the Indo-Pacific region. In this study, we sequenced and analyzed the mitogenome of . The nearly complete mitochondrial genome of is 15,694 bp in size.

Distribution and density of Jonas, 1844 relate to sediment while reproduction shows multiple peaks per year in Cat Ba-Ha Long Bay, Vietnam.

Jonas, 1844 is of great commercial interest, but its reserves have dramatically declined over recent decades. Therefore, there is an urgent need of scientific basis to propose effective fishery management measures and improve artificial aquaculture of the clam. In this study, we investigated the distribution and density of , sediment characteristics, and established the clam's reproductive cycle through monthly observations from August 2017 to July 2018.

DNA barcoding of coastal ray-finned fishes in Vietnam.

DNA barcoding based on a fragment of the cytochrome c oxidase subunit I (COI) gene is widely applied in species identification and biodiversity studies. The aim of this study was to establish a comprehensive barcoding database of coastal ray-finned fishes in Vietnam. A total of 3,638 specimens were collected from fish landing sites in northern, central and southern Vietnam.

Sequencing and analysis of the complete mitogenome of (Cuvier, 1804).

is a common nudibranch in the tropical and sub-tropical Indo-Pacific region. In this study, the complete mitogenome of from Vietnam was recorded for the first time. The circular mitogenome had a size of 14,421 bp and consisted of 37 genes (13 protein-coding genes, two ribosomal RNA genes, and 22 tRNA genes).

Comparative extraction and simple isolation improvement techniques of active constituents' momilactone A and B from rice husks of by HPLC analysis and column chromatography.

This paper reports comparative extraction efficiencies and enhancement methods for natural herbicidal (growth inhibitors) compounds, momilactone A and B, respectively from the dried husks of using different extraction techniques and different solvent systems. Four different extraction techniques . percolation, agitation with heat, sonication and soxhlet using five solvent systems as ethyl acetate, acetone, acetonitrile, methanol and methanol:water (8:2) were evaluated.

The status and distribution of PCBs along the coast of Vietnam.

Polychlorinated biphenyls (PCBs), well-known as an important scientific achievement, are now considered as one of the most persistent organic pollutants (POPs) that need to be strictly controlled and forbidden worldwide (the Stockholm convention on POPs). Vietnam is one of the countries that encounters with serious issues from PCB contamination. This study presented a comprehensive review on the status and contamination of PCBs along the coast of Vietnam.

Sequencing of two mitochondrial genomes of endangered form of the Sevan trout .

The two complete mitochondrial genomes of endangered form of the Sevan trout are published in this paper. The mitochondrial DNA (mtDNA) is 16,677 base pairs (bp) in length and contained 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The overall base composition of the genome in descending order was 29.

Analysis of complete mitochondrial genome of (Arthropoda, Decapoda, Xanthidae) with phylogenetic consideration.

The complete mitochondrial genome is sequenced and analyzed from a xanthid crab which is the first complete mitochondrial genome for the genus. The mitochondrial genome length of is 16,435 bp and it is composed of 13 protein coding genes, two ribosomal RNA genes, and 22 tRNA genes. The structure and gene orientation of the mitochondrial genome is identical with the other brachyuran records.

Analysis of complete mitochondrial genome of fiddler crab (De Haan, 1835) (Arthropoda, Malacostraca, Decapoda).

In this study complete nucleotide sequences of the mitochondrial genome of fiddler crab (De Haan, 1835) were determined and characterized. The length of mitochondrial genome for is 15,955 bp. This is the third and the longest record of complete mitochondrial genome from the family Ocypodidae.
