Road, Kolkata 700019, India Introduction India has a long coastal stretch of 8085 kms This type of farming, however, resulted in the deterioration of water quality and created negative impact on health of supporting aquaculture as the predominant activity. The culture of Penaeus monodon is practiced in the brackish water system of the country with the aim to increase the fish production basically for human consumption. Its other benefits include employment generation, food security and general improvement in the livelihood of the people in remote islands and deltaic complex like Indian Sundarbans (located at the apex of Bay of Bengal). To attain its full potential in contributing to human development and social empowerment, the culture of Penaeus monodon requires new approaches that are realistic and achievable in the context to current environmental circumstances [1]. Over the last decade, culture of P. monodon in Indian Sundarbans has witnessed an exponential growth when semi-intensive method of shrimp farming was at its peak. Research Article Open Access Abstract Traditional method of tiger prawn culture is a common practice in Indian Sundarbans which is done without any sound scientific back-up, proper feed and water quality management. The shrimp farmers use traditional feed of animal origin that often results in fouling of water quality and disease outbreak in cultured species. The present paper highlights the effect of total replacement of animal ingredients in shrimp feed with floral ingredients on the water quality and shrimp health. Weight gain, condition index, feed conversion ratio (FCR), survival, body pigmentation (astaxanthin level) were analyzed in shrimps along with pond water quality. Higher condition index (C.I.) values, survival rate and gain in shrimp weight were observed in experimental pond (E) compared to control pond (C). Low FCR values were observed in the experimental pond than the control pond. Astaxanthin values in shrimps of the experimental pond were also higher than the control pond which points towards Catenella repens as the source of carotenoid in the shrimp tissue. Cost-benefit analysis also proved better yield and profit in case of experimental pond indicating the sustainability for the present venture. *Corresponding author: Abhijit Mitra, Department of Marine Science, University of Calcutta, 35 B.C.
