Fig 1.
Degradation categories for salmon lice were defined as follows: (0) no apparent degradation, (1) slight signs of degradation, and (2) significant signs of degradation (left).
The 11 adult female salmon lice and one mobile salmon louse found in a lumpfish stomach at four days incubation time (right).
Fig 2.
Probability of recovering lice at various degradation levels over time for the two developmental stages, presented in relation to temperature (upper panel) and freshness (lower panel).
A degradation level of 3 indicates that the louse was no longer visually detectable.
Fig 3.
The probability of recovering adult female and mobile salmon lice from lumpfish stomachs across different sampling times.
Full lines are from the non-parametric survival analysis, and broken lines are from the fitted parametric survival regression. ‘+’ indicates sampling points.
