“…All the macro invertebrates encountered are known to be commonly occurring in tropical riverine areas. The occurrence of an organism or species group in a particular environment has been explained by the ability of the species to adapt to the various ecological influences on the organism (Ndome et al, 2011). All the stations appeared to be apparently uniform.…”

Present study was conducted in the lower Meghna River and its Estuary at Chandpur, Barisal, Bhola, Hatiya and Sandwip during monsoon and post-monsoon season. A total of 17 major taxa were identified of which 10 and 15 were recorded during monsoon and post-monsoon season respectively. Macrobenthos abundance was comparatively greater during post-monsoon than monsoon. The water at lower Meghna was slightly acidic in both seasons. Salinity, soil pH and water temperature were found to be responsible for the variations in benthos assemblage (p<0.05). Canonical Corresponding Analysis (CCA) also indicated that most of the macrobenthos had close dependency to salinity, water temperature, soil pH, organic carbon and organic matter both in monsoon and post-monsoon. Benthos diversity (H') did not show much temporal variation (0.92±0.52 and 0.85±0.40 for the monsoon and post-monsoon seasons respectively). The highest macrobenthos diversity (H') was 1.53 at Bhola and the lowest was 0.29 at Chandpur both during the monsoon season. The macrobenthos evenness (J') also showed less variation between seasons (0.64±0.32 and 0.51±0.26 during monsoon and post-monsoon respectively). The maximum evenness value was found at Sandwip (0.95) during the monsoon season whereas the minimum value was at Barisal (0.20) during the post-monsoon.

The invasion of mangroves forest by nypa palm is said to affect the ability of the mangroves to act as a spawning ground for fishes. It is thus hypothesized that nypa palm presence in mangrove forest will impact their fish spawning ability due to the reduction in plankton population. A total of four stations were chosen: station 1 (open water), Station 2 (nypa palm dominant), station 3 (Rhizophora and Avicennia dominant), Station 4 (Mixed forest). Results of water quality parameters include; pH (6.99 ± 0.16), temperature (28.20°C ± 0.05°C), DO (4.71 ± 0.18 mg/L), conductivity (19.52 ± 0.20 µm/s), salinity (10.76 ± 0.07 ppt) and TDS (13.45 ± 0.27 ppt). Mean values of the physico-chemical parameters were not significantly different from each other (P > 0.05). In all 737 zooplankton in eleven genera were collected. Copepoda dominated with 75.1%. Similarly, 4774 phytoplankton in six taxa were collected. Bacilliarophyceae dominated with 87.45%. Shannon Weiner index across the stations was highest in station 4 (0.36) and lowest in station 1 (0.33). Margalef's index was highest in stations 2, 3, and 4 (3.48) and lowest in station 1 (2.67). Pielou's index of evenness was highest in station 4 (0.099) and lowest in station 1 (0.089). The composition and abundance of plankton showed no significant difference across the four stations (P > 0.05). This implies that the presence of Nypa fruticans (Wurmb) did not have negative impact on the abundance and diversity of plankton.
