Table B1
Length-weight relationship for Coregonus lavaretus collected during gillnetting standardized surveys and with additional data from fisheries for Lake Annecy, based on theequation log (W) = log a + b log(L) (a: intercept and b: slope of the equation). Sample size (N); length (L) in mm; weight (W) in g; minimum (min) and maximum (max) of L & W; Standard error (SE); coefficient of determination (r2), p is the significance of regression (p) with p significant at <0.05.
