Herein, we studied the ichthyofaunal diversity of the Bidyadhari River in the Indian Sundarbans for three consecutive months (April 2018-June 2018. The fishes collected in this study were netted from two collection points using bag nets. We also measured some environmental parameters during the time of netting. From the collection, we determined the Simpson's index of diversity (1-D), the Shannon-Wiener index (H), evenness (E) and the Sorenson's coefficient of community (CC) to find out the species richness, abundance, evenness and the levels of similarity of the two collection points. We also converted the H values to their true diversities (effective number of species [ENS]) for an adequate comparison. The indices and coefficient (H = 3.72-3.94, E = 0.830-0.832, 1-D = 0.973-0.979 and CC = 0.87) indicate that the overall integrity of biodiversity of the two collecting points is high. From the true diversity values, we ascertained that the first point, having 62 species of fishes, is 1.24 times as diverse as the second one, having 50 species. We have attributed the fish diversity to a compound of abiotic and biotic factors, which we explain in the discussion part. We also documented 20 fish species, new records for the Indian Sundarbans; some are new records from West Bengal. Furthermore, we discuss the possible reasons for their occurrence. Our study brings the number of fish species recorded from the Indian Sundarbans to 378.

Composition and diversity of larval fish in the Indian Ocean using morphological and molecular methods

et al. 2021

Although vital in fisheries management, no comprehensive studies on ichthyoplankton have been conducted in Sri Lankan waters in the north central Indian Ocean hitherto. Hence, this study is the first detailed account of diversity and species composition of larval fish based on samples collected during the southwest monsoon in 2018. In total, 80 species belonging to 69 families were identified using morphological and molecular methods targeting the COI gene. The larval fish diversity varied significantly between regions: east (North East, Central East, and South East) and west (North West, South West, and South). In their larval stages, mesopelagic families were associated with the offshore waters whereas demersal and pelagic families were related with shelf regions in the South, South East, and Central East. The larvae of pelagic families are likely dispersed by the South Monsoon Current from the west to the east regions, while demersal fish seem to be confined to the same area as conspecific adults. The most abundant larval species observed were Selar crumenophthalmus, Cubiceps pauciradiatus, and Dipterygonotus balteatus. High abundances of several commercially important larval tuna species were found in the South East, Central East, and South regions indicating that these waters could be important nursery grounds. Furthermore, Callionymus simplicicornis was recorded for the first time in the Indian Ocean, and seven additional species were found new to Sri Lankan waters. The results from this study also highlight the importance of using combined morphological and molecular methods and the need for strengthening fish nucleotide databases in poorly studied areas of the Indian Ocean.
