Prawn and fish farming is an important source of income and employment for the local populace in the Sunderban region in West Bengal. These have led to a dynamism in the local economy in these areas. The results of this study suggest that the impact of this development has been skewed, whereby a small section of the population with access to capital has enjoyed substantial benefits and a large majority of the population was left out of the development trajectory.

Antimicrobials used in salmon aquaculture pass into the marine environment. This could have negative impacts on marine environmental biodiversity, and on terrestrial animal and human health as a result of selection for bacteria containing antimicrobial resistance genes. We therefore measured the numbers of culturable bacteria and antimicrobial-resistant bacteria in marine sediments in the Calbuco Archipelago, Chile, over 12-month period at a salmon aquaculture site approximately 20 m from a salmon farm and at a control site 8 km distant without observable aquaculture activities.
