Poultry litter generates toxic biocycle in fish tanks [http://cmsenvis.cmsindia.org/resources/newspaper/details.asp?id=83332]
Highly putrefied poultry litter being used as feed in fish tanks in Andhra Pradesh is generating a toxic biocycle.
The litter, when added to fish tanks, contaminates the water and increases the fluctuation of biological oxygen demand (BOD). It also accentuates the ectoparasite problem, leading to ulcers in fish. To control the parasite, fish farmers use highly toxic
pesticides which penetrate into the biocycle posing a serious health hazard to the end consumer.
