An attempt has been made for taxonomic identification of coral-associated fish through morphological studies. Mostly dead and few live fishes were collected from local fishermen, fish landing zone, and fish markets in St. Martin’s Island, Bay of Bengal, Bangladesh, from October 2015 to July 2016, visiting seven times. Samples were also obtained from local boys who collected fishes by using hook and line. The study recorded the first occurrence of 16 coral-associated fish species such as Caesio cuning, Lethrinus ornatus, Upeneus suahelicus, Upeneus asymmetricus, Scarus taeniopterus, Scarus zufar, Bodianus neilli, Parapercis clathrata, Parapercis diplospilus, Pomadasys furcatus, Siganus fuscescens, Acanthopagrus berda, Gerres erythrourus, Lagocephalus spadiceus, Psettodes bennettii, and Heteroconger perissodon. Among them, Parapercis clathrata, Parapercis diplospilus belongs to the family Pinguipedidae before, no spec...

To justify the identification of a widely distributed species, Sillago sihama from the Bay of Bengal, Bangladesh, an integrated approach including morphology and DNA barcoding was used. Two unrecognized species of Sillago, i.e., Sillagomuktijoddhai sp. nov. and S. mengjialensis sp. nov., were identified from the coastal area of Bangladesh. S. muktijoddhai sp. nov. has marked differences in the body color, anal fin color, number of gill rakers, snout length, and swimbladder. S. mengjialensis sp. nov. has notable differences in the anal fin color, snout length, and swimbladder and is distinguished from S. muktijoddhai sp. nov. by the body color and swimbladder. The morphological characters of 14 documented Sillago species with two posterior extensions of the swimbladder were referenced and distinguished to accredit the two new species. Genetic analyses of partial mitochondr...

Although there is difficulty in identifying accurately goatfish solely on the basis of morphology, U. vittatus and U. supravittatus were confirmed by both using morphological characters and DNA barcoding cytochrome oxidase I subunit (COI) approach for the first time in St. Martin’s Island, Bay of Bengal, Bangladesh. Increased number of species of the genus Upeneus was found in Bangladesh from 3 to 5 and extended the distribution range. Asiat. Soc. Bangladesh, Sci. 45(2): 161-173, December 2019

Twenty one individuals of 8 species of Lutjanus were collected from local fishermen. Both morphological characters and DNA barcoding approach by mitochondrial cytochrome oxidase I subunit (COI) were used to confirm the identification of all species. Present study recorded the first national occurrence of two reef associated Lutjanus species (L. xanthopinnis and L. indicus). In addition six species (L. rivulatus, L. lutjanus, L. vitta, L. lemniscatus, L. fulviflamma and L. johnii) were re-described. Distinct morphological differentiation were found between more closely related species L. xanthopinnis, L. vitta and L. lutjanus. Three different appearances of L. johnii, two different appearances of L. rivulatus and L. lemniscatus were confirmed as same species. Phylogenetic analysis showed monophylotic clade for conspecific indiv...
