3.3 | Microbial complexity of fish gut flora
A total of 2,300 OTU were obtained
for all the four fishes. A total of 223 OTUs were shared by all species
(9.7%), while 332 (223 + 42 + 47 + 20) OTUs (14.4%) were shared by
herbivorous and carnivorous (Figure 2). The herbivorous fish had
relatively higher number of unique OTUs (467) equivalent to 20.3%
followed by omnivorous fish (251 OTUs) representing 10.9%, while
filter-feeder fish had 113 OTUs equivalent to 4.9% and carnivorous fish
had only 43 OTUs making up 1.9%.
