The respiratory system is influenced by the marine pollutants. According to the guidelines of Integrated Teacher Education Programme (ITEP), the integrated studies of Earth, Oceans, marine water and it's pollution, teleost fishes and respiratory system of teleost fishes are essential to complete the studies and researches and making the course of studies at various levels of Biology.
