Morphological and molecular evidence supports the first occurrence of two fishes, Siganus sutor (Valenciennes, 1835) and Seriolina nigrofasciata (Rüppell, 1829) (Actinopterygii: Perciformes), from marine waters of Odisha coast, Bay of Bengal, India

A new record of Plectropomus pessuliferus (Serranidae: Epinephelinae) wasdocumented based on morphological characters and DNA barcoding. The species was collectedduring a regular survey for making an inventory of reef associated fishes in Saint Martin`sIsland, Bangladesh. This is the first report of roving coral grouper from the marine waters ofBangladesh validated by morpho-meristic analysis and DNA barcoding. This is also the firstreport from the northern Bay of Bengal.

The present study reports a new record of two marine fishes Filimanus similis (Feltes 1991) and Naso unicornis (Forsskål 1775) from Bangladesh waters. The specimens were collected from Saint Martin’s Island and Cox’s Bazar fish landing canter, Bangladesh. The specimens were diagnosed by analyzing their morphometric characters and DNA barcoding. The study also reports Naso as the first species of the genus ever recorded in the marine waters of Bangladesh.

AbstractSurveys for shushuks Platanista gangetica were conducted during January to April 1999 in Kaptai Lake and the southern rivers of Bangladesh. A population of at least 125 dolphins was recorded in the Karnaphuli and Sangu rivers and connecting canal. The overall encounter rate was 0.76 dolphins per km. Density was highest in the lower reaches of the Sangu, where we recorded 1.36 dolphins per km. These rates are fairly high when compared with other areas of shushuk distribution. Dolphin movements in the Sikalbaha–Chandkhali Canal were consistent with it being used as a corridor for migration and dispersal between the Karnaphuli and Sangu. Shushuks were also sighted in marine waters of the Karnaphuli and Sangu river mouths, adding credibility to the hypothesis that dolphins move along the coast between the Ganges–Brahmaputra–Meghna and Karnaphuli–Sangu systems, perhaps during the monsoon when freshwater plumes extend into the Bay of Bengal. No dolphins were nobserved in Kaptai Lake, a dam-created reservoir of the upper Karnaphuli, despite reports of occasional sightings by local fishermen. No shushuks were observed in the Bagkhali and Matamuhuri rivers, possibly because of seasonal-closure dams present near the mouths of both rivers. The main threats to dolphin survival in the Karnaphuli-Sangu system are probably accidental entanglement in monofilament gillnets, bioaccumulation of persistent contaminants and possibly collisions with motorized vessels and a decline in prey as a result of over fishing. The most significant conservation measure that could be taken would be to establish a protected area for dolphins in the Sangu River below the Dohazari Bridge.

The Bangladeshi reef fish species have not been studied thoroughly. 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 species was recorded under this family from Bangladesh and a rare and endemic species, Scarus zufar, of the Arabian Sea off Dhofar (Zufar), Oman in the Western Indian Ocean, was recorded for the first time in the Northern Indian Ocean in the northeastern part of Bay of Bengal. This study increased the number of coral-associated fish from 240 to 256 species and the number of families from 54 to 55 in the coral reef ecosystem of the Bay of Bengal, Bangladesh. Bangladesh J. Zool. 48(2): 263-288, 2020
