Length-mass relationship for sockeye salmon captured in Chignik Lake by natal origin.

<p>These populations are referred to in the text as Black Lake emigrants and Chignik Lake residents. Circles are individual fish and the lines represent the AICc selected model. For 2010 and 2011, the best fit model contained different intercepts and slopes by natal origin. However, for 2011 this model differed less than 2 AICc units from a model with the same slope and intercept for both stocks (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058584#pone-0058584-t002" target="_blank">Table 2</a>).
