In this setting, we control for endogeneity bias and truncation in the sea lice data. The statistical analysis determines the effect of different treatments on the salmon growth profile. The model also allows identifying the effect that factors such as center location, environmental conditions, sea lice abundance in the area, have on salmon growth. We simulate how unit production costs vary with different treatments and center characteristics, and estimate the impact of treatments costs on unit production costs. Our results indicate that lice generate an important increase in unit costs, basically because its negative impact on the salmon production cycle and that sea lice treatments in the form of chemical baths, although expensive, do reduce unit production costs.
