Estimation of external infection pressure and salmon-louse population growth rate in Faroese salmon farms
Managing salmon lice Lepeophtheirus salmonis outbreaks is a crucial part of salmon aquaculture in sea cages.

Managing salmon lice Lepeophtheirus salmonis outbreaks is a crucial part of salmon aquaculture in sea cages.
