Chondrus crispus Stackhouse is an economically important red alga that is farmed extensively throughout the Maritime provinces of Canada. Little is known of the population structure of this alga. A comparison of the ITS sequences of isolates from a variety of locations in the Maritimes and Europe indicated sequence similarity. In contrast, a protein isozyme study of Chondrus crispus tentatively concluded extensive genetic differentiation. Our initial aim was to develop the AFLP technique for use with red algae and, secondarily, to perform a small scale population study for Chondrus crispus. We examined ten isolates from each of ten populations in the Maritime provinces of Canada and these data will be discussed.
