(A) The microbiome similarity tree constructed by the annotated microbiota, which demonstrates the highest similarity between amberjack and tuna, as well as cobia and salmon, with the tilapia distantly related to the other fish types. (B) The relative abundance of Photobacterium spp. DNA in salmon significantly exceeds that in tuna based on a paired comparison of all the restaurants that we investigated (Paired t-test; P = 0.0079). Each line represents a restaurant.
