Nguyen V. T., Nguyen D. T., Lai P. H., & V. G. Gagarin, 2007. Fauna of free-living marine nematodes in Can Gio mangrove forest of Ho Chi Minh city , Vietnam (IEBR proceeding - inpress)

Summary:
During 2004-2006, the fauna of brackish water nematodes in Can Gio mangrove forest had been investigated. Twenty stations located in the transfer zone, aquacultural zone, polluted industrial zone and core zone had been chosen to monitor in the wet season and the dry season. 129 species belonged to 73 genera of 24 families were recognized, among them one genus and 32 nematode species were described as the new species for science. In 10cm2 sediment sample the average of nematode density was 1853 individuals, in the transferring zone was 1337 individuals, in the core zone was 2627 individuals. In the wet season, the average of nematodes was 2281 inds, higher than in dry season - in November was 1950 inds. In the dry season the density of nematode community fluctuated from 12 inds (CG2) to 13741 inds (CG12). Family Xyalidae was the most abundant, with 20.6 - 27.5% individuals; The second position was family Comesomatidae, with 15.4% - 20.4%, the third place occupied family Linhomoiidae, with 15.2% -15.5 % and last one was family Axonolaimidae, with 8.5% - 12.1%. In both seasons nematodes predominantly were following species: Terschellingia sp.2., Terschellingia sp.4, Neochromadora sp. Theristus sp.3, Hopperia sp.1 and Paracomesoma sp.2. Others species such as Halipectus sp.2, Pseudolella sp.2, and Halalaimus sp.5 distributed mainly in the wet season, on the other hand species Theristus sp.2, Gomphionema sp. and Theristus sp.3 only recognized in the dry season.


Nguyen D. T., Le H. A., & V. T. Nguyen, 2007. The species diversity of benthic copepods (Harpacticoida) in Can Gio mangrove, Ho Chi Minh city , Viet Nam (IEBR proceeding - inpress)
 
Summary: The first result on species composition of benthic Harpacticoid - copepods (Harpacticoida) in Can Gio mangrove was given. In total 16 species of Haparticoids were identified. Recognized hapacticoid species belonged to 11 crustacean families such as Tachidiidae, with 3 species; Ameiridae,Diosaccidae and Canthocamptidae, represented with 2 species, Cletodidae, Ectinosomidae, Clytemnestridae, Cletodidae, Harpacticidae, Arcythompsoniidae and Laophontidae represented with only 1 species. The density of Harpacticoid community was low, fluctuated from 2 inds to 14 inds/10 cm2.

Most common and predominant Harpacticoid species in all investigated stations of Can Gio mangrove was Nitocra lacustris, with 36.26%. This species was found only in the core zone and characterized by undisturbed unpolluted water, with a sanility concentration fluctuated from 0.11% to 0.22%.
