Figure 17. Surfclam length-frequency distributions over time in the shallow NNJ Stratum 88.  Clams were sampled from 1982 – 2002 with the NMFS clam dredge on the RV DE-II.  In 2004, samples were made with the commercial dredge on the FV Lisa Kim, which might have lower retention of small clams (<90 mm) compared with the NMFS dredge.
