Microbial diversity in fish: an editorial

Subha Ganguly

It is well known that the structure of the digestive tract varies among different fish species. The differences are significant depending on the developmental stage of the fish. Therefore, the structure of the digestive tract is the first factor that influences the formation of bacterial communities in the digestive tract. The formation of normal microbiota is a complex process that occurs in the digestive tract of fish larvae and juveniles and depends on the food of fish spawning (laying large numbers of eggs in the water) and the microbiota of the surrounding water. Many investigations have been carried out to study the formation of microbiota in the digestive tract of carp from juvenile to adult fish, and it has been confirmed that the formation of bacterial flora in the fish digestive tract is a step-by-step process. The most dominant genera that inhabit the digestive tract of fish are Aeromonas, Pseudomonas, Clostridium, and Bacteroides.
