MEIOFAUNA IN THE ORGANIC SHRIMP FARMS OF MANGROVE FOREST, CA MAU PROVINCE

Meiofaunal communities in the organic shrimp farms (OSF) of Ca Mau province was investigated in 8 ponds (Tam Giang Commune, Nam Can District). Results showed that the meiofauna, especially Nematode communities at the Tam Giang’s organic shrimp farms (TGOSF) in Ca Mau mangrove express high densities and biodiversity and Nematoda dominate numerically in the mangrove meiofauna (73.69 to 96.2 %). In total, 15 major taxa were found with the dominant taxa belonged to three dominant groups: Nematoda, Copepoda, and Rotifera. The densities of meiofauna ranged from 287 ± 132.9 to 3,129 ± 1,388.6 inds.10 cm -2 . Seventy fifth nematode genera belonging to 24 families with the most important typifying genera were Terschellingia , Daptonema , Parodontophora Ptycholaimellus , Sabatieria , Hopperia , Anoplostoma Gomphionema . The TGOSF in the study area was characterized by homogeneity and stabilization.
