Dragraking impact on Irish moss (Chondrus crispus) frond size structure / by J.D. Pringle and R.E. Semple.: Fs70-8/87-91E-PDF

"Chrondrus crispus Stackhouse has been intensively cropped by dragrakes off western Prince Edward Island for 20 yr. Here we attempt to assess the impact of this harvest on frond class (based on frond dichotomy number) size structure by comparing samples from dragraked and non-dragraked Marine Plant Harvesting Districts (MPHD). Frond size class frequency distribution in the former district was biomodal, with peaks in abundance at Classes 0 (no dichotomies) and 6 (six dichotomies). This distribution was unimodal in the latter district with peaks at about Class 7"--Abstract, page 2.
