| Abstract: | Three cultivars of Sorghum bicolor (L.) Moench (grain sorghum, forage sorghum, and a sorghum sudangrass hybrid) were evaluated as planted forages for crawfish (Procambarus spp.) in two simulated culture systems, double cropping and crawfish monoculture. Based upon ease of culture, biomass production, and biomass degradation characteristics, grain sorghum and sorghum sudangrass exhibited great potential for either system. With the added advantage of grain production, grain sorghum represents the more attractive option and may provide farmers with a viable alternative to rice for double cropping with crawfish. The sorghum sudangrass produced large amounts of vegetative biomass and also represents a worthwhile forage option for the crawfish fanner. Either of these plants is conveniently incorporated into existing farm operations and could provide options as producers strive to integrate crawfish aquaculture with conventional agriculture. |
