520 $a Nutrient additions every 5 to 7 days resulted in no significant difference in <italic>P. mollis</italic> growth compared with daily nutrient additions. The addition of <italic>f</italic> medium trace metals (Guillard and Ryther, 1962) significantly increased growth compared with additions of PO4<super> −</super> and NO3<super>−</super> alone. The use of NaNO3 as an N source was found to be superior compared with NH 4NO3. <italic>Palmaria mollis</italic> growth was most sensitive to phosphorus additions, with a declines in growth above concentrations of 83.3 μM - P d<super>−1</super>.
520 $a <italic>Palmaria mollis</italic> growth was positively correlated with concentrations of dissolved inorganic carbon. A pH of 8.9 produced growth rates that were not significantly different than at pH 8.3. A seawater flushing regime that increased flushing during the light cycle but lowered flushing during the dark cycle resulted in growth rates equal to those obtained by maintaining pH at 8.5 with CO2.
520 $a At a specific light density (SLD) of 0.0048 to 0.036 mol photons g<super> −1</super>[fw]d<super>−1</super>, growth was highly correlated with light. Growth was best at a salinity of 30 ± 1&permil; and a temperature of 12°C for low light and 14° to 18°C at high light. Growth under higher temperatures was correlated with increased light. Lowering culture temperature at night from 15°C to 11°C significantly increased growth compared with a constant daily temperature of 15°C.
520 $a There was no significant difference in growth of <italic>Haliotis discus hannai</italic> cultured in seawater compared to seawater supplemented with PO4<super>−</super>, NO3<super>−</super>, and 0.75<italic>f</italic> + Zn (d<super>−1</super>). The Japanese abalone <italic> H. discus hannai</italic> showed the highest growth when fed on <italic>P. mollis</italic> supplemented with nitrate loads ranging from 1176 to 2353 μM d<super>−1</super> NO3<super>−</super> - N and the red abalone <italic>H. rufescens</italic> when fed on <italic>P. mollis</italic> supplemented with nitrate loads of 2353 to 2942 μM d<super>−1</super> NO3<super>−</super> - N. Both abalone species grew better on <italic>P. mollis</italic> supplied with 0.75<italic>f</italic> + Zn (d<super> −1</super>) trace metal solution (Guillard and Ryther, 1962).
