Shrimp culture has high prospect in the socio-economic framework of Indian Sundarbans. However, the activity has considerable impact on the ambient environment in terms of water quality. The present programme has scanned the aquatic environment of 10 shrimp culture ponds at 10 different sampling stations of Indian Sundarbans with respect to surface water temperature, salinity, pH, transparency, nutrients, oil and grease and phytopigment levels along with the Condition Index of the cultured shrimps. The selected ponds are exposed to varying degree of anthropogenic pressure on the basis of their proximity to the highly urbanized and industrialized city of Kolkata and threats posed by brick kilns, tourism related pressure, non-scientific methods of shrimp culture etc. The health of the shrimp was found better at Bali and Chotomollakhali, where the adverse impact of city sewage is minimum and shrimp feed was scientifically formulated to maintain the water quality.

Abstract


Shrimp culture has high prospect in the socio-economic framework of Indian Sundarbans. However, the activity has considerable impact on the ambient environment in terms of water quality. The present programme has scanned the aquatic environment of 10 shrimp culture ponds at 10 different sampling stations of Indian Sundarbans with respect to surface water temperature, salinity, pH, transparency, nutrients, oil and grease and phytopigment levels along with the Condition Index of the cultured shrimps. The selected ponds are exposed to varying degree of anthropogenic pressure on the basis of their proximity to the highly urbanized and industrialized city of Kolkata and threats posed by brick kilns, tourism related pressure, non-scientific methods of shrimp culture etc. The health of the shrimp was found better at Bali and Chotomollakhali, where the adverse impact of city sewage is minimum and shrimp feed was scientifically formulated to maintain the water quality.
