The challenges faced by fish larvae are especially arduous and numerous because of their relatively small size, which limits their abilities to thwart predators, starvation, and transport to detrimental environs (Miller ., 1988;

This has been accepted as more or less axiomatic, both on theoretical grounds (Cushing, 1974; Rothschild, 1986) and because field observations demonstrate that mortality decreases with the age of the fish (Z

The critical issue, in such cases, is whether the phenotypes of survivors differ consistently from those of individuals that perish.
