Application of an in situ growth model: inferred instance of interspecific trophic competition between anadromous fishes of Prudhoe Bay, Alaska
摘要
A previously described in situ growth model was used to predict the summer growth of age-1 and age-2 broad whitefish Coregonus nasus. The model was able to predict growth in 1991 and 1992 with mean squared errors (MSE) of 3.0 and 1.8 mm for age-1 fish and 6.5 and 21.2 mm for age-2 fish. Poor model fit for both year-classes in 1990 was attributed to a divergence of observed from predicted growth. Data suggest that the divergence in growth began at the time of a massive immigration of least ciscoes C. sardinella into the delta.
