Dataset for "Salmon louse infestation impairs the lifetime fitness of sea-run brown trout"

Dataset Description for Manuscript

This dataset is associated with the manuscript titled "Salmon louse infestation impairs the lifetime fitness of sea-run brown trout." It contains capture-recapture data for trout collected as part of a field study in the Herøyosen fjord basin, Norway, focusing on the effects of salmon louse infestation on trout survival. The data aligns with the methodology and findings described in the manuscript, providing a basis for the analyses and conclusions presented.

Dataset Columns:

ID: Unique identifier for each trout individual.

Stasjon: Capture station (e.g., "Aureholen" or "Baldersvagen").

Breddegrad: Latitude of the capture location.

Lengdegrad: Longitude of the capture location.

Species: Species of the captured individual (all "trout").

Method: Capture method used ("Trapnet").

Tag_ID: Unique identifier for the PIT tag implanted in each trout.

Mass (g): Mass of the trout in grams.

FL(mm): Fork length of the trout in millimeters.

TL(mm): Total length of the trout in millimeters.

Cop, Ch1, Ch2, PreAd: Counts of salmon lice at different developmental stages:

Cop: Copepodid stage.

Ch1, Ch2: Chalimus stages.

PreAd: Pre-adult stage.

ADM, ADF, Cal: Counts of adult male, adult female, and caligus (another ectoparasite) stages.

Dorsalfindamage: Indicator of damage to the dorsal fin.

detection2021, detection2022, detection2023: Detection status in PIT antennas or recapture events for each year (dates if detected; blank if undetected).

N_lice: Total count of salmon lice observed on the individual.

Key Notes:

Study Focus: This dataset underpins the analyses performed in the manuscript, particularly the statistical modeling of survival probabilities as a function of salmon louse burden.

Capture Details: Wild trout were captured during their early marine migration using trap nets, measured, tagged with PIT tags, and monitored for lice infestation.

Tracking and Survival: The PIT tag system facilitated tracking of individual trout over multiple years, enabling survival analyses presented in the manuscript.

Louse Infestation Data: Salmon lice counts are broken down into developmental stages, reflecting infestation pressure and its impact on survival.
