Relationship between weight (g) and total length (cm) of A. saxatilis: (4) weight (g) as a function of the total length (cm) of the fish. Black circles, fish that were alive at the end of the experiment (n = 53); white circles, fish that died during the experiment (n = 14). (5) Weight/length ratio versus fish length, with separate linear regressions for living (solid line) and dead (dashed line) fish, and respective r2 values.
