Effect of physico-chemical parameters on fish health

Abstract

In many regions of the world, fish are an economical source of protein and an essential cash crop, and water provides physical support for their life processes, such as feeding, swimming, reproduction, digestion and excretion. So for survival and survival, good water quality is really important. The consistency of water is defined in terms of its chemical, physical and biological content. Temperature, pH, salinity, and dissolved oxygen are some essential physical and chemical parameters affecting the aquatic environment. Others are total solids suspended and dissolved, total alkalinity and contaminants of acidity and heavy metal. The restricting criteria for the reproduction of fish organisms (flora and fauna) are these parameters. Poor water quality can result in low benefit, poor quality of the liquid and possible risks to human health. Production is decreased if the water includes pollutants that may affect the cultivated species' development, growth, reproduction or even trigger mortality.
