In comparison with previous morphological attempts at fish egg identification in the northeastern United States (Colton and Marak (1); Berrien and Sibunka (2)), the eggs of our barcoded species fit into 3 general categories: category I (6 of our 50 species) are eggs that have never before been identified to the species-level as eggs; category II (33 species) describes eggs that have historically been identifiable only at higher taxonomic levels (genus or family) or at the species level during specific stages of development (i.e., eggs at mid to late stages); and category III (11 species) contains eggs that are well described and can be identified confidently to species level through the use of morphological criteria at all stages of development (Table 1).
