Abstract

Phytoplankton and zooplankton are integral part of any aquatic ecosystem. They not only serve as food for aquatic animals,

but also play important role in maintaining the biological balance and quality of the aquatic ecosystem. Raipur is a district

of Chhattisgarh which is having about 58,514 ponds covering an area of about 0.744 lakh ha and these ponds have high

plankton diversity. The present work has been conducted to enlist phytoplankton and zooplankton genera occurring in a

few perennial unmanaged urban and rural ponds of Raipur, Chhattisgarh. Among phytoplankton, a total of 67 algal genera

belonging to the classes Chlorophyceae (29 genera), Bacillariophyceae (18 genera), Cyanophyceae (15 genera),

Chrysophyceae (2 genera), Euglenophyceae (2 genera) and Dinophyceae (1 genus) have been recorded from the studied

ponds while among zooplankton, a total of 24 genera belonging to the classes Rotifera (11 genera), Copepoda (7 genera),

Protozoa (3 genera), Cladocera (2 genera) and Ostracoda (1 genus) have been recorded during the study period. Results of

the present study depict that the studied ponds have high plankton diversity.

INTRODUCTION Pond is relatively a shallow body of standing water; an

aquatic ecosystem which is generally rich in biodiversity.

On the other hand, plankton are the integral part of any

aquatic ecosystem. The term plankton refers to organisms

which have drifting habitat and includes all forms of both

macro and microscopic life which floats free in water or if

motile, are unable to swim against currents. The plankton

community is comprised of phytoplankton and zooplankton

[1].

Phytoplankton are free floating unicellular, filamentous and

colonial autotrophic forms of aquatic habitat whose

movement is more or less dependent on water currents [2].

They are the major primary producer in many aquatic

systems forming the first trophic level in the food chain and

are the important food source for other organisms of that

system [3]. They not only serve as food for aquatic animals,

but also play an important role in maintaining the

biological balance and quality of the aquatic ecosystem

[4,5]. The qualitative and quantitative studies of

phytoplankton have been successfully utilized to assess the

quality of water [6-9]. Several phytoplankton species have

served as bio-indicators [10-13] and it is a well suited tool

for understanding water pollution studies [14]. On the other

hand, zooplankton are integral components of aquatic food

webs and contribute significantly to aquatic productivity in

freshwater ecosystems; they are having the ability to swim

or move freely. They constitutes important food item for

many fishes; the larva of carps feed mostly on zooplankton

[15]. Zooplankton also play an important role in the food

chain as they are second in trophic level as primary

consumers and also contribute to the next trophic level

[16]. Phytoplankton are being fed by zooplankton and

facilitates the conversion of plant material into animal

tissue and in turn constitute the basic food for higher

animals including fishes, particularly their larvae.

Zooplankton are the major mode of energy transfer

between phytoplankton and fish [17]. Zooplanktons have

been considered to be the ecological indicators of water

bodies [18] and their biomass abundance and species

diversity have been used to determine the conditions of

aquatic environment [19].

Chhattisgarh (17o46'- 24o5' N latitude and 80o15'- 84o20' E

longitude) is a state of central India. Raipur is a district of

Chhattisgarh; the climate of the region is hot and sub

humid. This particular region receives 1200-1400 mm of

annual rainfall normally, out of which about 85% is

received during the rainy season (late June to October) and

15% during the winter season (November to January). The

maximum temperature ranges from 17-45.2°C and

minimum from 8-22°C during the year. May is the hottest

and December is the coolest month of the year. Raipur

constitutes around 58,514 ponds covering an area of about

0.744 lakh ha and these are having high plankton diversity

[20].

The primary objective of the present study was to record

and disseminate the information on plankton biodiversity

existing within some freshwater ponds of Raipur,

Chhattisgarh in order to serve as an updated and

contemporary biodiversity database for future references.

MATERIALS AND METHODS The survey was conducted intermittently during 2012-2014

in total seven perennial unmanaged urban and rural ponds

of Raipur, Chhattisgarh to enlist phytoplankton and

zooplankton genera commonly available there. Details

of the sampling sites have been presented in Table 1 and

Figure 1. Plankton samples were collected during early

morning. 10 liters of water sampled from different areas

and depths of the pond was filtered through 25 μ mesh

plankton net. The collected sample was then concentrated

in 30 ml receptacle glass tube, attached at the end of the

plankton net. Plankton samples were then preserved in

phosphate buffered formalin @ 3% concentration along

with one drop of glycerin. After that the preserved samples

were kept in refrigerated condition for further analysis.

Plankton was identified up to generic level following

earlier documented plankton identification key and

monographs [1, 21-25]. Phytoplankton was classified under

different classes: Cyanophyceae, Chlorophyceae,

Bacillariophyceae, Dinophyceae, Euglenophyceae and

Chrysophyceae [25] while zooplankton was classified

under the following classes: Protozoa, Copepoda, Rotifera,

Cladocera and Ostracoda [21]. All plankton samples were

identified under LABOMED TCM-400 compound light

emission binocular microscope. Microphotographs were

obtained intermittently from collaborative institutions viz.

Central Inland Fisheries Research Institute, Barrackpore;

Central Inland Fisheries Education, Salt Lake and

Zoological Survey of India, Kolkata through submitted

plankton samples. Microphotography was done with

CATCAM microscope photographic attachment and with

Plankton Identifier software v1.1.

Therefore, the results of the present study are depicting the

presence of high diversity of both phytoplankton and

zooplankton in the studied rural and urban ponds of Raipur,

Chhattisgarh and in this way also suggesting a healthy

ecosystem available in these ponds. The phytoplankton

diversity which has been observed in the present study is in

close resemblance to the earlier observation made by [20]

who reported a total of 52 algal genera belonging to the

classes Chlorophyceae (21 genera), Cyanophyceae (12

genera), Bacillariophyceae (16 genera) and Eugleno-

-phyceae (3 genera) from the urban and rural ponds of

Raipur, Chhattisgarh. Algal genera belonging to two

classes i.e. - Chrysophyceae (Dinobryon sp. and Synura

sp.) and Dinophyceae (Ceratium sp.) observed in the

present study was not reported earlier by [20], thus giving

first time evidence of their presence in this region. These

algal classes are indicative of the accumulation of organic

load in the bottom sediment of water bodies and are often

considered undesirable for fishes due to their associated

toxins when they bloom [25]; though in this study no such

algal bloom of these classes has been observed.

On the other hand, the zooplankton diversity observed

in the present study is quite different from the observation

earlier made by [20]; most of the genera under protozoa

(Zoothamnium sp., Arcella sp., Diffugia sp. and

Centrophyxis sp.) and cladocera (Bosmina sp.,

Diaphanosoma sp., Moinodaphnia sp., Macrothrix sp. and

Alona sp.) reported earlier by [20] have not been observed

5 International Journal of Research in Biological Sciences 2016; 6(1): 1-6

in the present study. However, the generic diversity of

copepods and rotifers are almost similar as reported by [20]

and [26] earlier from the same area.

Current study though has been conducted in some selected

rural and urban ponds of Raipur, this will help to get an

overall idea about the phytoplankton and zooplankton

diversity present here and will surely help for further study

related to this field. Studies alike will help to create region

wise plankton biodiversity maps and provide knowledge

regarding the types of plankton that can be expected in a

particular region of India. Moreover, the mere existence or

unavailability of a particular plankton community or genera

can be related with the prevailing agro-climatic conditions

of any region, if similar studies will be extensively

conducted throughout India or published reports are

compiled into region specific and time framed plankton

databases.
