Fish feed on chicken dung
You’d think after the BSE skandal in the 1990’s (which was most probably precipitated by feeding cattle with ground-up bones and carcasses) that we would have learnt the error of our ways, but I see that it is now standard practice in Asia to feed chicken dung to fish. It is a United Nations recommended fish-farming technique, the Independent reports today:
... a technique firmly backed by the UN’s Food and Agriculture Organisation (FAO) as a primary means of providing protein for mushrooming populations in developing countries.The only reason it has come to the fore at the moment is because experts fear the the dung may represent a reservior (pun intended) of disease which is then transferred to migrating birds.
Known as integrated livestock-fish farming, the technique involves transferring the wastes from raising pigs, ducks or chickens directly to fish farms.
