By changing the feeding frequency and feeding level and so on, we explored the different effects on growth of sea anemone oral disc. The experimental results showed that, arenaceous substrates and no stocking substrates have no significant influence on the growth rate of the sea anemone oral disc, and the stocking density at 33.3 ind/m², 50.0 ind/m², 66.7 ind/m², 88.3 ind/m² and 100.0 ind/m² had no significant influence on the growth of the sea anemone oral disc. But the feeding frequency and feeding level did. The individual oral disc growth rate was found to decrease to 0.84% with feeding frequency at 4 d per time, but with high feeding frequency at 1d per time,2 d per time and 3 d per time, the individual oral disc growth rate was above 1.30%; and the low feeding level below 1.0 g/d led low individual oral disc growth rate to 0.97%, and higher feeding level over 1.5 g/d led higher oral disc growth rate to above 1.25%.
