Figures & data
Figure 1. Channel catfish featuring different susceptibilities (panel A, resistant fish; panel B, susceptible fish) to Flavobacterium columnare (columnaris disease) show disparate numbers of mucus-producing goblet cells in the gill (indicated by black arrows). 200X magnification. Periodic acid Schiff technique.
Figure 2. The complex interactions of environment, host, pathogen, and microbiome in catfish aquaculture pose challenges, but also offer numerous points of manipulation for research and production improvements. Arrows illustrate numerous connections and feedback mechanisms among the biotic and abiotic factors impacting catfish mucosal barriers.
