Main-culture techniques for freshwater pomfret (piaractus brachypomus) in shallow ponds
Among existing ponds, shallow ponds still account for a very large proportion. Such ponds are shallow, lack matched drainage and irrigation systems, and some are formed by seasonal flooding; when traditional fish species are farmed in them, fish yields are low and returns are very poor. To explore ways to increase production, income and efficiency in such ponds, for two consecutive years from 1993 to 1994, we conducted a "trial of main-culture of freshwater pomfret in shallow ponds" in three ponds with a total area of 9.7 mu and a maximum water depth of 1 m. Without aeration facilities, satisfactory results were achieved: in 1994 the average yield per mu was 227 kg
