First Report of the Red Algal Genus Chondria C. Agardh (Rhodomelaceae, Rhodophyta) for the Marine Flora of Bangladesh

Abstract

Epiphytic algae in mangrove forests contribute to high productivity in these unique mangrove ecosystems. A general survey of mangrove-associated macroalgae was conducted during February-March (dry season) and November-December (wet season) in the Sundarbans Mangrove Forest, Bangladesh. Different macroalgae were collected from mangrove pneumatophores, roots, and branches of trees. During this survey, a small and inconspicuous species of Chondria was encountered from the upper-middle of the intertidal zone in the Malancha River (22 • 5 11.37" N and 89 • 13 12.37" E). External-internal anatomical traits were examined and the sample was identified as Chondria intertexta Silva, a new record for the algal flora of Bangladesh. Furthermore, its geographical distribution and some other ecological notes are also discussed.

Culture of Three Seaweed Species in Cox’s Bazar Coast, Bangladesh

“…In Bangladesh seaweeds are naturally abundant in the littoral and sub-littoral zones of coastal and Sundarbans mangrove areas. Around 200 species belonging to 77 genera of seaweeds have so far been recorded from the Bangladesh coast by various studies and new species are included in the list (Aziz 2015, Islam et al 2019, BFRI 2019, Mamun et al 2020. These include 29-47 species of green seaweeds, 35-59 species of brown seaweeds, and 69-94 species of red seaweeds.…”

Final Remarks of Special Issue “Biodiversity of Macroalgae”

“…Despite the relevant ecological role of macroalgae, there are still many areas of the world where our knowledge about macroalgal diversity has important gaps. For example, in this volume, Islam et al [6] reported for the first time the presence of the genus Chondria for the marine flora of Bangladesh. Moreover, Mantri et al [7] provided in this volume a comprehensive review of the current knowledge of macroalgae in India, as well as significant inputs about their economic potential.…”
