Trout immune system discovery could help improve aquaculture vaccines

Researchers from the Salinas Lab at the University of New Mexico are the first to identify an immune structure in the nasal cavities of rainbow trout, giving fish immunologists greater insights into their biology and opening the door to better aquaculture vaccines.
