Carbon Sequestration and Carbon Footprint in Some Aquaculture Practices in West Bengal, India
Journal Title: International Journal of Zoology and Animal Biology - Year 2021, Vol 4, Issue 2
Abstract
The present investigation on carbon sequestration and carbon footprint in some aquaculture practices in West Bengal, India was conducted from the six fish ponds, two from the Nadia, two from North 24 Parganas, one from Purba Medinipur, and one from Bankura districts of West Bengal. The polyculture consisting rohu, catla, mrigal, silver carp, and grass carp are being practiced by the farmers. Sometimes, they also culture monopia with these carp species. The average culture period was four months, and usually the farmers practices two crops in a year. The farmer from Bankura practices for eleven months culture. The water depth varied from 1.2 to 2.1 m. The fish production varied from 27300 to 35400 kg/ha with an average of 31690±3469kg/ha. The water pH was neutral to alkaline. The other parameters, viz., dissolved oxygen; total alkalinity, total hardness, and ammonium nitrogen were within the optimum range for good aquaculture practices. The pond sediment was slightly acidic. From fertility status point of view, organic carbon was low to medium, available nitrogen was low to medium, and available phosphorus was low.
