Technique of main culture of freshwater Pomfret in shallow ponds
Among the existing ponds, shallow ponds still account for a large proportion. The water of this kind of pond is shallow, the drainage and irrigation is not matched, some are seasonally flooded into ponds, breed traditional fish, produce little fish, the benefit is very low. In order to explore the ways to increase production, increase income and increase efficiency of this kind of ponds, for two consecutive years from 1993 to 1994, we have a total area of 9.7 mu and a maximum water depth of 1. 5%. The experiment of main culture of freshwater Pomfret in shallow ponds was carried out in rice ponds, and satisfactory results were obtained in the absence of oxygen enrichment facilities: an average yield of 227 kg per mu in 1994.
