Seasonal and Spatial Variations of Meiofauna Communities in Correlation to Environmental Characteristics in the Organic Shrimp Farms of Tam Giang Commune, Nam Can District, Ca Mau Province

Abstract

Environmental factors and meiofauna communities in the organic shrimp farms located in Tam Giang commune, Nam Can District, Ca Mau province were investigated in March (dry season), July (transfer season) and November (wet season) of 2015. The results recorded that the environmental factors were not quite optimal for shrimp farming such as the high percentage of TN and TOC and anaerobic condition in sediment. The results were also indicated that DO, TOC and TN showed significant correlation with characteristics of meiofauna communities. Following results were indicated that the meiofauna communities were expressed as the high abundance and slightly biodiversity that is a rich natural food sources for shrimp in the organic shrimp farms ponds. Further more, nematoda dominate numerically in the meiofauna communities.
