I have been going through and raking out the larger stones (1"+) partially to help encourage the Brazil nut effect, but I mainly continue to do it because I've noticed the pigs prefer to wallow where it isn't so gravelly. What changed, fundamentally, is the market for renewable natural gas, [and] the market for carbon, have allowed us to develop a business model, an economic model, that works for everybody involved," Westerbeek says.

Besides this, ducks feed on a variety of organisms such as weeds, snails, unwanted harmful insects and their larvae (some being vectors of fish pathogenic organisms), tadpoles, frogs and water-borne disease-causing organisms infecting man, whose eradication is one of the important aspects of farm management.

I'm not discrediting what is happening, just wondering if the same results would have happened regardless if pigs were introduced.The most intensive type of poultry production is the battery type of housing, which is installed by the side of the pond. I also need to decide what plants I want to introduce to the pond and pond edges but I have the winter to ponder that. In such farming paddy and fish are grown together and harvesting the paddy and fish at the end of the rice-growing season. Such suitable strains when used, approximately 50-60 per cent of their droppings when falls into the pond, is sufficient to fertilise the water.

Speculations are ripe that integrated fish farming with pigs and poultry may be a cause of influenza pandemic. It has three sides, is only one pallet tall in height, and it has a metal roof on it to keep the rain out. Generally organic manures are preferred over the use of fertilisers in the preparation of the paddy-fields. For such a cultivation the farm should have addi­tional holding or rearing facilities for the period between paddy harvesting and planting of new fish seedlings. It can be reared on kitchen wastes, industrial or agricultural by-products and also slaughterhouse offal.

Although duck and fish farming have been in practice in eastern Europe and China and their com­patible nature being recognised since long, the inter­action and benefits of the association have been understood only a few years back.
