Detailed Ecological Assessment Report 2008 – Keenjhar Lake
than three meter deep, high ratio of dissolved oxygen and low ratio of turbidity
were also found. All these factors are favourable for production of
phytoplanktons; many kinds of birds were found in the area which is a good
indicator of the good water quality which can sustain marine life. The findings of
the winter survey prove to be better than the summer season results.
• Blue green algae: The samples were crushed and taken from rocks,
boats, and from corner sides; marine water was also very turbid with silt
particles. The algal species were disturbed temporarily but not destroyed
due to high tides, turbidity and storm (what storm). The random method
was used at the time of collection (this should be in methodology).
Filamentous and multi-cellular algal species were directly picked with help
of forceps and latest equipments when collection became difficult
• Xanthophyta: One species belongs to the genus Ophiocytium of the
phyla Xanthophyta as recorded. All the species have flagella so they are
included in Flagellales group. They move easily with the help of flagella in
water body.
• Grass green algae: 6 species belonging to 3 genera of the phyla
Chlorophyta, e.g. Cladophora, Oedogonium, Spirogyra etc. all the genera
produce good food for aquatic life in which Spirogyra produce huge mates
in large area even usually cover the small plants of mangrove forest, it is
also found on epiphytic condition in marine water as small piece of wood,
Spirogyra attached such piece of wood float freely in water body, with help
of boat collect.
• Charophyta: Three species belongs to one genus Chara of the phyla
Charophyta were recoded. The species of the genus Chara have capacity
to produce excellent food for fishes, aquatic fauna etc.
