Biodiversity of phytoplankton from polyculture milkfish and white shrimp vanname pond culture waters, Pekalongan region

Abstract

The objectives to study the effect of Biodiversity of Phytoplankton on the productivity in Polyculture Milkfish and White shrimp vanname Pond Culture waters, Kandang Panjang Pekalongan Region, Centre of Java. Methodology The sampling have tried station T1,T2,T3,T4 were in pond culture of polyculture waters to identify a phyto planton in polyculture pond Kandang Panjang waters. The sampling was carryout between Pebruary to Mei 2018. The result study showed that the value of the diversity indices in T1 treatment obtained the value of diversity indices (H' = 1.093), T2 obtained diversity values (H' = 1,072), T3 found (H' = 1,804) and T4 showed (H' = 1,907). The similliarity indexs are T1 (values, E = 0.765), values (E = 0.606), T3 ((E = 0.785) and T4 (E = 0.895).The dominance indices values phyto plankton showed T1 (value D = 0.725), T2 (D = 0.606,), T3(D = 00.595) and T4 (D = 00.578).The diversity indices showed higher vlues at T4 showed variety of diversity indices (H' = 1,907).sampling site as compared to other three (T1,T2, and T3).During experiment showed the water quality of pond culture polyculture milkfish and white shrimp vanname was in viable condition.
