Effect of fertilizers and supplementary feeding on water quality and plankton productivity in fish ponds under uniform fish stocking density
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 3
Abstract
Studies were conducted to investigate the effects of different fertilizers and supplementary feed on water quality parameters. Dissolved oxygen levels were higher in nutrient rich and plankton dense ponds. There were quite minor variations in water quality parameters among treatments and different seasons of the year. Values of alkalinity and hardness remained same irrespective of the type of input. Total solids were much higher in those ponds with both types of fertilizers and supplementary feed. Differences were more prominent in the levels of plankton productivity which was always higher in nutrient dense ponds where all the proposed inputs were present. During the winter months this difference however totally mitigated indicating low metabolic and decomposition activities. So it can be concluded that water quality can be maintained within acceptable ranges if all the inputs are added in well measured and managed way. Haphazard and poorly managed activities always lead to deleterious effects.
