AbstractThe growth of Chondrus crispus plants in tanks of fertilized and unfertilized seawater at Sandy Cove, Halifax Co., and Meteghan, Digby Co., Nova Scotia and Pointe Sapin, New Brunswick was compared during June to August 1974. The selected strain of Chondus crispus, T4, grew more rapidly and produced more carrageenan than locally harvested plants. The effect of low nitrogen availability during periods of rapid growth on production was observed only at Halifax (T4) and Meteghan (local plants) whereas in 1973 this effect (Neish effect) was observed at all four test locations. A weight loss occurred when locally harvested plants were grown in unfertilized sea water at Pointe Sapin. The relative number of tetrasporic plants also decreased.
