Shrimp farming in India has recorded remarkable growth during the last three decades especially in coastal states. Optimum use of prospective areas and expanded farming practices has not only provided wonderful opportunity to farmers residing along coastal areas but also brought them prosperity. Most of the shrimp culture farmers were used chemicals for their culture. In the present study, an attempt has been made to culture Litopenaeus vannamei without any chemicals. The water was filled during high tide at least 2 hours every day based on seepage. This was continued until harvest. This activity actually brought minerals and fresh oxygen to the culture pond. The water quality variables were measured at regular intervals in organic shrimp pond during the production cycle (September 6th, 2022 and October 25th, 2022). Ninety eight percent survivals were noticed in the present experimental study. The average shrimp length was ranged from 10.8 cm to 13.8 cm and the size ranged between 10 g to 15 g. The animals were active, shown fast growth and disease free throughout the study period. To standardize the organic farming, the culture was terminated at 50 days of culture. The study indicates that organic farming discourages the use of various chemicals in all stages of culture. Chemical use is prohibited throughout the culture period. Hence, no health problems are reported which enhance consumer preference in future. The students and farmers were trained in the organic shrimp pond.
