Benthic meiofaunas developed naturally in aquaculture systems, where detritus is utilized as a primary food source.
Warwick [6] stated that almost all juvenile stages of culture species fed on benthic meiofaunas while they were available.
Twenty species of benthic meiofaunas namely harpacticoid copepoda, ostracoda, gastropoda, crustacean nauplii, nematoda, bivalvia, polychaeta and insecta were found in the present investigated ponds (Table 2).
Bell and Coull (1978) showed that the grass shrimp Palaemonetes pugio was fed on meiofaunas, causing a marked reduction of numbers in a salt marsh habitat.
Compared with the reported studies [5,21] this study concluded that some of the benthic meiofaunas such polychaeta decreased with the culture period probably due to predation of shrimps.
