Abstract: Naturally occurring stable isotopes are commonly used to elucidate the origins of organic matter and food web complexity within marine communities. Given the utility of these natural dietary tracers, few studies have attempted to use stable isotopes to examine the early life feeding ecology of pelagic fishes in offshore marine ecosystems (Bode et al, 2007; Pepin and Dower, 2007). Food web tracers, such as the stable isotopes of carbon and nitrogen (δ 13 C and δ 15 N) were used to determine the extent to which fish larvae rely on different components of the ecosystem. Stable nitrogen isotopes becomes enriched at successive tro- phic levels, resulting from the greater concentration of the light isotope ( 14 N) than the heavy
