The constant exposure of the fish branchial cavity to aquatic pathogens causes local mucosal immune responses be extremely important for their survival. Here, we used a marker T lymphocytes/natural killer (NK) cells (ZAP70) and advanced imaging techniques investigate lymphoid architecture zebrafish cavity. We identified sub-pharyngeal organ, which tentatively named “Nemausean organ” (NELO). NELO is enriched in T/NK cells, plasma/B antigen-presenting embedded network reticulated epithelial cells. presence activated lymphocyte proliferation, but not V(D)J recombination or hematopoiesis, suggests that secondary organ. In response infection, displays structural changes including formation cell clusters. gill tissues form cohesive unit within large network. Collectively, reveal an unreported organ reminiscent mammalian tonsils evolved multiple teleost families.

Increased industrialized production of salmonids challenges aspects concerning available feed resources and animal welfare. The immune system plays a key component in this respect. Novel ingredients may trigger unwarranted responses again affecting the well-being fish. Here we review our current knowledge salmon intestinal anatomy, immunity, digestive physiology microbiota context feeding regimes. We point out gaps indicate promising novel technologies to improve salmonid health.
