Breathing to identify suitability of water quality of inland fish species

Abstract

Laboratory condition of the fish breathing range are recorded and found that fish breathing is an environmentally controlled. The breathing range of Channa striatus may varies from 40 to 52 per minute through their gills and once in a every few minutes through air. A higher breathing rate indicates that the fish is under aquatic environmental stresses. Major purpose of such experimentations is to data capture and data generation in fisheries research which is more academic in nature. It also helps in deriving the logical method of determining aquatic stress environment for every species. Usually, lower the breath value of an individual species may specify the suitability of aquatic environment for such species.
