Lepeophtheirus salmonis infections represents an important limitation to sustainable salmon farming today. Vaccines against these ectoparasites have the potential to be cost-effective means of controlling infestation and avoiding the disadvantages of chemical treatments. In this project the vaccine antigen TT-P0 potential against salmon lice was explored at lab-scale. Results showed good potential of TT-P0 vaccine in controlling these ectoparasites in 1st generation by affecting the adult female count and fecundity with greater presumptive potential effect in 2nd lice generation. This is a very important preliminary documentation of TT-P0 vaccine as preventive measure. Further validation is necessary to study long-term effectiveness.
