    • Age-0 Sablefish Size and Growth Indices from Seabird Diets at Middleton Island, Alaska

    Metadata Updated: July 6, 2024

    This dataset provides annual summaries of information on age-0 sablefish in Rhinoceros Auklet (Cerorhinca monocerata) chick diets from Middleton Island, Alaska. This includes number of diet samples, number of sablefish sampled, proportion of total biomass, catch per unit effort, and frequency of occurrence for each year.

      We calculated an annual growth index for age-0 sablefish using the relationship between mean length by day and Julian day for each year (OLS[F = 24.44, df = 61, 184]: R^2 = 0.85, p < 0.001). From this model, growth (in mm per day) is the slope, and predicted length (in mm) is the length on the median Julian day = 205 (July 24). Annual anomalies of growth and length are calculated for each variable by subtracting the mean of all years.
