Summary of measurements

168 dredge hauls 0.5 nautical miles apart in 5 layers, distributed by random
sampling based on the abundance of young scallops in the previous survey.
For each haul, the following steps were performed:
-Counting, measuring and determining the age of scallops.
-Identifying, counting, measuring and taking otolith samples from flat fish.
-Identification and counting of macrofauna.
-Short description of the type of bottom.
-Approximate quantification of sea stars, brittle stars and crepidula.
