Early Succession of Community Structures and Biotic Interactions of Gut Microbes in Megalopa after Desalination.

As an enduring Chinese freshwater aquaculture product, the has a high economic value and is characterized by a catadromous life style that undergoes seawater-freshwater migration. However, little is known about their gut microbial status as they move from saltwater to freshwater acclimatization. Here, we sampled and cultivated megalopa from three aquaculture desalination ponds and investigated their gut microbiota diversity, community structures and biotic interactions from megalopa stage to the first juvenile stage after desalination for 9 days.
