A high-quality genome assembly of the Laotian shad (Tenualosa thibaudeaui), an endemic species of the Mekong River Basin.

The Laotian shad (Tenualosa thibaudeaui) belongs to the family Clupeidae and is mainly distributed across Lao PRD, Cambodia, and northern Thailand. Due to overfishing and dam reconstruction, the Laotian shad is on the verge of extinction and currently listed as vulnerable by the IUCN. Nanopore and Illumina sequencing data were integrated to generate the first high-quality genome assembly for T.

Molecular phylogenetics of the Clupeiformes based on exon-capture data and a new classification of the order.

The Clupeiformes, including among others herrings, anchovies, shads and menhadens are ecologically and commercially important, yet their phylogenetic relationships are still controversial. Previous classification of Clupeiformes were based on morphological characters or lack of synapomorphic characters. More recent studies based on molecular data as well as new morphological evidence are keeping challenging their phylogenetic relations and there is still no consensus on many interrelationships within the Clupeiformes.

First report of de novo assembly and annotation from brain and blood transcriptome of an anadromous shad, Alosa sapidissima.

Objectives: American shad (Alosa sapidissima) is an important migratory fish under Alosinae and has long been valued for its economic, nutritional and cultural attributes. Overfishing and barriers across the passage made it vulnerable to sustain. To protect this valuable species, aquaculture action plans have been taken though there are no published genetic resources prevailing yet.

A high-resolution genome of an euryhaline and eurythermal rhinogoby (Rhinogobius similis Gill 1895).

Rhinogobius similis is distributed in East and Southeast Asia. It is an amphidromous species found mostly in freshwater and sometimes brackish waters. We have obtained a high-resolution assembly of the R.

Cross-species gene enrichment revealed a single population of Hilsa shad (Tenualosa ilisha) with low genetic variation in Bangladesh waters.

Tenualosa ilisha is a popular anadromous and significant trans-boundary fish. For sustainable management and conservation of this fish, drawing an appropriate picture reflecting population status of this species is very essential based on their all-strategic habitats in Bangladesh. In this study, 139 samples from 18 sites were collected and cross-species gene enrichment method was applied.

Health risk estimation of metals bioaccumulated in commercial fish from coastal areas and rivers in Bangladesh.

Metal contaminations in commercial fish have become a great public health concern worldwide including Bangladesh. The current study was conducted to provide preliminary evidence of nine metals in three commercially significant fish namely Pampus argenteus, Sardinella longiceps and Tenualosa ilisha collected from four coastal stations- Kuakata, Pathorghata, Cox's Bazar, and Pirojpur, and eight stations of five rivers- Padma, Meghna, Jamuna, Katcha, and Nobogonga in Bangladesh. High magnitudes of Pb (0.

Ecological risk and source apportionment of heavy metals in surface water and sediments on Saint Martin's Island in the Bay of Bengal.

The study aimed to determine eight hazardous heavy metals in surface water and sediment samples collected from the Naf River, Shah Porir Dwip (estuary), and mostly around Saint Martin's Island in the Bay of Bengal. The results of heavy metals in water samples were ranged as Pb 14.7-313.
