Fig. 2. (A) Scope for growth as a function of oyster origin. (B) Clearance rate of oysters as a function of temperature x origin. The inset shows clearance rate as a function of oyster origin only (main effect). (C) Oxygen consumption rate of oysters as a function of temperature (left) and date (right). Oysters were collected in the field or produced in the hatchery. Five males and 20 females were mated to produce animals in the pooled group (Pool) whereas F_x represents full-sib families. Data are means ± s.e.m., n=3 aquaria. Data from different temperatures and times were pooled together when these effects were not significant. Different letters indicate significant differences.
