Abstract/ Executive Summary:

Eight newly recorded phtyoplankton belonging to the algal Order Volvocales, Chlorococcales, Penales and Cryptomonadales from Bangladesh have been described in the present paper. The taxa are Collodictyon sparsavacuolatum Skuja, Tetrachloridium carteroides (Pascher et Jha) Huber-Pest., Chlamydomonas bicilliata Korsch., Chlorogonium liostracum Strehlow, Asterarcys cubensis Comas, Nitzschia hybrida Grun., Rhodomonas lens Pascher and Ruttner and R. ovalis Nygaard.

Objectives:

A further detail investigation on these samples was carried out to see the quality of phytoplankton other than the members of Euglenophyceae

Methodology:

Gani et al. (2011) furnished detailed information on this lagoon together with the sampling procedures. Samples were collected by sieving 100 liter of sub-surface water through plankton net having a mesh aperture of 20 μm. The concentrated plankton sample in the bucket of the plankton net were taken in a screw caped glass vial and fixed with Lugol's solution. A definite volume of well mixed sample was mounted on a Helber Bacteria Counting Chamber and photomicrographed with the help of a Nikon Optiphot, UFX-11A microscope fitted with a Nikon FX-35WA camera, Japan. Taxonomic features of the interesting taxa were measured and recorded at the same time. The taxa were identified using Huber-Pestalozzi (1983, 1968, 1961), Hustedt (1930) and Iyengar and Desikachary (1981).
