Age-related Dietary Patterns of Sympatric Adult Surfperch
Holbrook SJ, Schmitt RJ, Coyer J. 1985. Age-related Dietary Patterns of Sympatric Adult Surfperch. Copeia. 1985(4):986-994
Dietary separation between age-classes of adult black and striped surfperch (Embiotoca jacksoni and E. lateralis) was explored. Despite the fact that the sampled fish were locally sympatric and were capable of consuming the entire range of available invertebrate prey sizes and taxa, there were significant differences between diets of older (Age III-V) and younger (Age I-II) fish within each species. Intraspecific differences were of the same magnitude as interspecific dietary differences. Divergence in both sizes and taxa of prey contributed to the dietary separation.
