“…Copepoda and Rotifera are common zooplankton groups in many water bodies and a number of studies reveal Cladocera as the most dominant group of zooplanktons (Dorlikar 2018). Similar findings have also been reported by Akther (2015) from Bangladesh. However, Rotifers were dominating over the other zooplankton in Turkaulia Lake, Motijheel Lake, Kararia Lake, and Suraha Lake (Prasad et al 2009).…”

Planktons are the community of pelagic organisms, composed of different groups, which are in suspension in water and hence restricted mobility, often less than that of the water which carries them. The study was carried out during the winter of 2019 to observe the phytoplankton and zooplankton abundance and distribution in Ghodaghodi Lake, Nepal. Temperature, pH, electrical conductivity, dissolved oxygen, Secchi disc transparency, total dissolved solids, and turbidity were analyzed during the study. Collection of plankton samples were made by conical-shaped monofilament nylon plankton net of 90 μm mesh net size from approximately 10 ‐ 12 cm depth from six different sites. A total of 58 individuals of zooplankton were enumerated during the present investigation. The maximum number was counted for Mesocyclops sp (n=18) and minimum for Diaptomus (n=1). The highest zooplanktons were reported from site I (n= 12) and the lowest were reported from site II (n=7). Cladocera was the most dominating zooplankton group. A total of 85 individuals of phytoplankton were enumerated during the present investigation. The maximum number was counted for Spirogyra sp (30) and the minimum for Lamena sp (1). The most leading group of the phytoplankton was Chlorophyceae (30), followed by Cyanophyceae (13), Bacillariophyceae (7) and group Zygnematophyceae (6). Thus, these resources are also favorable for flourishing fish diversity in a lake ecosystem.

Zooplankton is microscopic organisms that drift in water due to the wave action of water. Zooplankton is mainly visible in the pelagic zone of ponds, lakes, rivers, and oceans where light enters. They have no strong swimming organ-like fin in fish [1]. That's why they are unable to swim freely like fish and they have relied on the wave or current to swim [2]. Zooplankton act as a base of food chains and food webs in freshwater ecosystems since they are solely liable for all secondary production [1]. Moreover, some of them are known as indicators of ecological variations [3]. Zooplankton is now subjected to the effect of the global climate change phenomenon and its long-term and wide profound effect [4]. Directly or indirectly omnivorous and carnivorous fishes rely on zooplankton for their food [5]. Zooplankton excretes organic matters and provides large quantities of protein in water. These nutrients are required for the development of different organs of fish that promote rapid growth [6]. Zooplankton regarded as the ideal food source for brood fishes. Carps fish larvae and white fish (Mullet) larvae mostly feed on zooplankton [7]. Zooplankton is the main food item of Xenentodon cancila and while Cirrhina reba's feed mainly constitutes of zooplankton [8]. About 82% of the food item of Anabas testudineus [9], 32% of Notoptrus notoptrus [10], 23% of Macrobrachium rosenbergii, 47% of Catla catla [11], 6.37% of Labeo rohita [11],

“…1 Microscopic zooplankton is known as the core of food chains and food webs and the primary natural food for fish and shellfish in all aquatic habitats. 2 Zooplankton has recently gained recognition as a crucial bio-indicator of ecological integrity. 3 Because of their high density, short life span, drifting nature, high species variety, and diverse tolerances to environmental stress, zooplankton is exploited as indicator organisms for the biological, chemical, and physical processes in the aquatic ecosystem.…”

“…19 Aquatic nitrogenous and phosphorus nutrients also regulate the diversity and distribution of zooplankton. 20 Some scientific research has been done in different ponds and lakes in Bangladesh, 2,17,18 although none of these investigations has thoroughly explained the existence, quantity, and seasonal dynamics of zooplankton. To make the fisheries sector sustainable and safe, extensive research is required on the aquaculture inputs used in ponds, influential environmental factors, and their effects on zooplankton.…”

Zooplankton is crucial for transmitting energy from primary producers to higher trophic levels. A study was done in a Bangladesh eutrophic fish pond to know zooplankton's seasonal dynamics in relation to environmental factors. There were 11 different zooplankton genera, which belong to three major classes: Copepoda, Rotifera, and Cladocera. Peak abundance of zooplankton was found in the spring and winter, respectively. Cluster analysis clearly indicated zooplankton abundance during the spring and winter. Rotifera was the main dominant group in the total zooplankton population. Copepoda and Cladocera had a lower abundance than those of Rotifera. During the study period, environmental factors were observed monthly. The total zooplankton abundance showed a positive correlation only with pH and a negative correlation with transparency, dissolved oxygen, phosphates, nitrates, and temperature during Pearson’s correlation coefficient analysis. The canonical correspondence analysis also indicated that pH, transparency, and temperature significantly affect the abundance of zooplankton groups. Therefore, further research on the influence of environmental factors on different species of zooplankton is strongly suggested for achieving sustainable fish production from eutrophic fish ponds.
