A study has found that there are  21 species of gobioid fish in mangrove and estuarine habitats. The Maharashtra forest department and Mangrove Foundation had commissioned the Bombay Natural History Society (BNHS) to study the diversity and distribution of gobioid fish in Maharashtra`s mangrove and estuarine areas.

The BNHS carried out this study from January 2020 to December 2021 at 25 sites such as small to large creeks, mudflats and mangroves.
