Aim: Local and global
stressors such as agricultural activities, climate change, habitat loss,
eutrophication and pollution are the major causes of declining fish
diversity. Therefore, for the management of fisheries and ecosystems, it is
important to know the fish diversity of Little Feni River. The study was
performed to know the diversity status of fishes in Little Feni River,
Bangladesh during April - December, 2015.
Methodology: Fishes and their
related data were collected from the Little Feni River of fish landing
centers, fish markets, interviewing fishermen and arotdar (or known as
Results: From this study,
47 species under 24 families were recorded in which 31 (66%) species were
from freshwater and the remaining 16 (34%) species were from marine sources.
Of the collected fishes, 26 species were categorized as not threatened (NT),
9 vulnerable (VU), 4 critically endangered (CR), 4 endangered (EN) and the
remaining 9 could not be classified under the said list due to data deficient
(DD). The results indicated the alarming decline of fish diversity in the
investigated area in general and/or perhaps in the country as whole.
investigation, appropriate evaluation and proper documentation are urgently
needed so that the public, investigators and policy makers would be able to
know about the current status of fish diversity, and can take initiatives for
proper conservation management practices towards the gradual decline of wild
