Abstract : Aquaculture is the fastest growing food practice in the world today. The biocides used in the agricultural crops reach the ponds and tanks as agricultural run off, which accumulates in the tissue of the fish body and interacts with the reproductive physiology and hinders the process of gametogenesis. As a result the fish production i.e. the yield will be highly affected & we will not be able to fill the millions of hungry open mouths for preventing them from malnutrition.
