Chile faces highest sea lice levels in eight years

Chile entered 2020 with the highest sea lice levels in eight years, a situation expected to contribute to tighter supply as the year progresses. Chile-based farmed salmon producers are continuing to move toward non-pharmaceutical sea lice treatment methods, but the industry still lags behind those in other regions in adopting mechanical treatment methods for the parasite that, while effective, are both costly and are still being tested under Chilean conditions. The increasing resistance of the fish to chemical treatments is one of the causes of the rise in sea lice.
