Abstract

This is the first approach to identification, abundance calculation; biomass analysis and diversity evaluation in two water bodies namely, Municipal pond and Bukvora baor at Jashore district, Bangladesh. The present study was conducted to find out the abundance and species diversity of plankton, water quality parameters in pond and baor environment. However, Municipal pond that is located at the central point of Jashore town and Bukvora baor that is located at sadar upazila in Jashore district. Study also concentrated on the comparison about abundance, species diversity and water quality parameters between pond and baor. Water samples were collected in each month throughout the study period from May, 2016 to August, 2016. Different water quality parameters such as air temperature, water temperature, dissolve oxygen; pH and transparency were measured in every month. The mean water parameters such as air temperature, water temperature, dissolve oxygen; pH and transparency were 30.4±2.30°C, 32.25 ± 2.6°C, 5.7±0.35 mg/l, 7.05 ± 0.39 and 19.9 ± 2.6 cm, respectively in pond. In baor, the mean water parameters such as air temperature, water temperature, dissolve oxygen, pH and transparency were 33.45 ± 1.19°C, 33.15 ± 1.49°C, 5.03 ± 0.15 mg/l, 8.45 ± 0.36 and 24.95 ± 2.6 cm, respectively. A total of 30 phytoplankton species have been found in the study area of which species under four groups; namely Cyanophyta (5), Heterokontophyta (3), Chlorophyta (11), Euglenophyta (2) have been identified and nine species were unidentified. Phytoplankton species distribution was not uniform. Chlorophyta species was most dominant group in both environments. Major four groups of zooplankton identified in study area both pond and baor; namely Cladocera (10%), Copepoda (55%), Ostracoda (3%), Rotifera (15%). In addition Nauplius (2%), Tunicata (4%), Insect larve (5%) fish eggs (6%) were also identified. Copepoda species was most dominant group in both environments. Plankton diversity was highest in June occurred in both environments. Keywords: Plankton abundance, biomass, diversity, municipal pond, Bukvora baor, Jashore, BangladeshCite this ArticleRaju RH, Md.
