A comparison of alternative methods for the estimation of age from length data for the Atlantic coast bluefish Pomatomus saltatrix


A comparison of alternative methods for the estimation of age from length data for the Atlantic coast bluefish Pomatomus saltatrix



U S National Marine Fisheries Service Fishery Bulletin 91(3): 534-549



Bluefish (Pomatomus saltatrix) are found along the US Atlantic coast from Maine to Florida, and are the object of a major recreational fishery as they migrate northward from the South Atlantic Bight in the spring and return southward in the late fall. Acceptance of analytic assessment results for bluefish has been hindered by the lack of a consistent time series of geographically comprehensive age-length keys for converting bluefish lengths to age. We used bluefish length-age data from North Carolina commercial fisheries during 1986 to 1989 to compare the utility of two simple methods for estimating age from length-frequency data with two more rigorous statistical methods. The simple methods were cohort slicing using von Bertalanffy growth parameters for bluefish and the application of a pooled age-length key compiled with data from different times and fishing areas. The two statistical approaches were the iterated age-length key method and MULTIFAN. Combined 1986-1989 proportions at age estimated by cohort slicing, pooled age-length key, and iterated age-length key methods were significantly different from those in the test data, based on a quantitative comparison using the Kolmogorov-Smimov cumulative distribution test. Proportions at age estimated by MULTIFAN were not significantly different from the test data. Our work suggests that MULTIFAN is the best alternative to a time series of fishery-specific age-length keys for the estimation of Atlantic coast bluefish ages from length data.
