Table 9. Type of formulated feed used for catla culture with advantage and disadvantage and the type of processing
Type of feed		Advantages	Disadvantages	Moisture	Processing techniques
				(% max)
Farm-made	Dry�	Use of locally available ingredients, easy to prepare using simple household machines. As moisture contain is less, it is more durable than moist feed.	Poor water stability, poor digestibility, higher FCR	10	Wet dough extruded�
					through a meat mincer�
					and sun dried�
	Moist	Easy processing, cheaper.	Highly perishable	>30	Wet dough
Industrially manufactured pellet
	Sinking	Good water stability and digestibility. Good for bottom feeders.	Not suitable for surface feeders like catla.	10	Pelleted form
	Floating	Good for surface feeders and larval fish.	Not useful for bottom feeders.	10	Pelleted form
