Experiments were conducted on Chondrus crispus, strain T4, to provide further information on conditions needed to obtain increased carrageenan yields from culture tanks. At low densities (0.15 lb per ft2), high N-content plants grown without fertillizer increased their dry matter and carrageenan content more rapidly than at higher densities. An initial density of 0.6 lb per ft2 produced the largest amount of carrageenan over a one month period. Green plexiglass filters placed over tanks inhibited the growth of green epiphytes but also reduced the growth of the Chondrus. Growth rate was greater under continuous illumination than under normal light-dark photoperiod. The rates at which plants grew in fertillized or unfertillized seawater decreased at temperatures above 21°C.
