The article discusses a study which examined the contributing role of jellyfish Phialella quadrata as vectors of bacterial disease for farmed salmon Salmo salar. Results revealed the likelihood that the damage to the fish gills was produced by nematocyst-derived toxins from the jellyfish and was compounded by secondary Tenacibaculum maritimum bacterial infection. Observation also showed the presence of the bacteria on the mouth of the jellyfish and the similarity of their deoxyribonucleic acid (DNA) sequences to those of the bacteria found on the salmon gills.
