Management for rice-fish

		(introduction...)
		Site selection: where to culture fish with rice'
		Preparation of field for Rich - fish culture
		Stocking for rice-fish culture
		Feeding and maintenance in rice-fish system
		Rice management in rice-fish culture
		Rice-fish benefits and problems
		The rice-fish ecosystem
		Fish as a component of integrated pest management (ipm) in rice production

The rice-fish ecosystem

Simplified nutrient flows

FERTILIZER - input of simple nutrients to the system

· Organic - available also to fish, plankton, algae, soil, fauna and bacteria
· Inorganic - available only to rice crops, macrophytes, algae, weeds, phytoplanktons and bacteria.

PHOTOSYNTHESIS - produces food from simple nutrients using sun's energy

- plants, algae and phytoplankton are food for fish, insects, zooplankton and soil fauna

DECOMPOSED MATERIALS - add to the detritus layer
BACTERIA - organisms which recycle materials back to simple nutrients
FISH - examples of various feeding groups
