Vibriosis disease is a major threat to the aquaculture industry caused by Vibrio spp. that are often resistant to antibiotics. Alternative controlling measures such as bacteriocins could be effective due to their narrow-spectrum activity. Hence, this systematic literature review (SLR) was carried out to review the feasibility of Vibrio spp. and their vibriocins to be used as a vibriosis control measure in aquaculture. A literature search using the web of science (WOS) and SCOPUS databases resulted in 42 unique articles which were reviewed. The results showed that Vibrio spp. could be used as a probiotic to control vibriosis, but not recommended due to their opportunistic nature and pathogenesis. Vibriocin showed narrow-spectrum activity against Vibrio spp. including highly pathogenic strains such as V. alginolyticus, V. harveyi, and V. parahaemolyticus. This supported this review's hypothesis of using vibriocin as a targeted vibriosis control measure. Vibrio cholerae was the most studied and showed the highest inhibition range, inhibiting 13 different vibrio and non-vibrio species. Various innovations were reported in the field and vibriocins can now be produced on large scales using whole-cell culture. Vibriocins were structurally diverse, large molecular weight, and relatively heat stable. These vibriocins mainly inhibited the cell wall but could have other novel mechanisms. These properties could affect the extraction process as well as applications in aquaculture, hence, should be considered in future research.
