Figures 3, 4 and 6 in the paper are the most interesting as they show:
A direct correlation between sea lice in the salmon farms and sea lice on juvenile out migrating salmon (figure 3 and 4a)
A decrease in sea lice on out migrating juveniles when the sea lice treatments at the farms are moved to reduce sea lice during the outmigration time frame (figure 4b) and
A huge change in the estimate mortality to juveniles as a result of the change in sea lice treatment protocols.
However, it should be noted that sea lice may become resistant to the current treatments so one shouldn't assume that treatment protocol alone will be a long term solution to the problem.
