Abstract/ Executive Summary:

Four species of damselfish viz., Pomacentrus proteus Allen, 1991; Pomacentrus similis Allen, 1991; Stegastes obreptus (Whitley, 1948) and Pomacentrus adelus Allen, 1991 have been recorded for the first time from the marine water of Bangladesh in the Saint Martin’s Island. The species were observed and captured photographs during monthly underwater survey from January to March 2018 on coral associated fishes in the Saint Martin’s Island located at the northern Bay of Bengal, Bangladesh.

Keywords: The Bay of Bengal, Saint Martin’s Island, Damselfish

Location: The Saint Martin’s Island is located at the southernmost tip of Bangladesh in the northern Bay of Bengal

Start Date: 00-01-2018

End Date: 00-03-2018

Program Area: Resource Development and Management

Commodity: Aquatic animal

Objectives:

To the new record of four damselfish species with their inventory in Bangladesh.

Methodology:

Underwater observation: The fishes were observed and captured photographs during monthly underwater survey by scuba diving in water depth of about 3- 5m from January to March 2018 in the southernmost part (locally called “Chera Dwip”) of the Saint Martin’s Island. The Saint Martin’s Island is located at the southernmost tip of Bangladesh in the northern Bay of Bengal (Coordinates: 20°34'–20°39' N and 92°18'–92°21' E) separated from the mainland by a channel that is about 9 km wide. Species were identified based on the morphological features of the photographs of fishes followed by the description of Allen et al. (2003), Allen (2001), Allen (1991) and Rahman et al. (2009).

Achievement/Findings:

Sourcing from different valid reports including present study, we have updated the checklist of damselfish of angladesh which indicates that 26 species of damselfish have been reported in the country until now. This study indicates the possibility of existence of more species of damselfish in Bangladesh that have been overlooked in past surveys.
