The concentration and accumulation of the metabolic by-product, lipofuscin, has determined to be an accurate measurement of chronological age in several types of crustaceans. Accurately determining the correct ages of American Lobster (Homarus americanus) individuals in harvests can assist in management options for preserving commercial stocks. In this study, I analyze the lipofuscin concentration in the Olfactory Lobe Cell Mass (OLCM) of 193 brain sections belonging to wild-caught H. americanus individuals inhabiting three different areas off the coast of Maine, while predicting their ages based upon their carapace length and latitudinal location. Data for the current study demonstrates that lipofuscin concentration in legal sized lobsters is dependent on carapace length, but not area collected. Furthermore, results indicate that legal-sized lobsters have older predicted ages, which is not dependent upon area collected.
