Abstract : Impact of fertilizer on mass production of zooplankton in pond was studied for three months in Patuakhali
Science and Technology University campus, Dumki, Patuakhali. Twelve ponds were selected for four treatments with three
replications. In which Treatment-4 (T4) was control treatment without any fertilizer. T1, (decomposed cow dung 3
kg/decimal, urea 300 gm/decimal and TSP 150 gm/decimal) produced cyclops 2-5/ml, Rotifer 1-2/ml, Moina 0-1/ml, other
zooplankton 2-4/ml and phytoplankton 4-5 /ml respectively.T2, (decomposed cow dung 3 kg/decimal, urea 300 gm/decimal
and TSP 150 gm/decimal and MOC 1 kg/decimal) produced cyclops 2-6/ml, Rotifer 1-2/ml, Moina 1-3/ml, other
zooplankton 3-5/ml and phytoplankton 6-8/ml respectively. T3, (cow dung 3 kg/decimal, urea 300 gm/decimal and TSP 150
gm/decimal MOC 1 kg/decimal and Mila 30 gm/decimal) produced Rotifer 5-6/ml, Moina 6-8/ml, other zooplankton 1-2/ml
and phytoplankton 12-17/ml respectively. The experiment showed that T3 did not produce any cyclops. It was evidenced
from the experiment that against the control condition the production of different plankton was significantly higher in all
treatments. Among the all treatments T3, (Liming + Cowdung + TSP + Urea +MOC + Mila) produced higher amounts of
Rotifera and Moina which can be used as an alternative food of artemia in shrimp and prawn hatchery.
