Figure 11. Efficiency corrected biomass estimates (‘000s mt meats), and 80% confidence intervals, for fully recruited surfclams, by region (NNJ, SNJ) and year.   Catch per tow was standardized to 0.15 nmi based on computed tow distances (SENDIST_2004). Only good, random tows were included (RANDLIKE = 1 or 2). For NNJ and SNJ, full recruits were defined as those 120 mm and greater.
