【 摘 要 】

Cultivated mussels (Perna perna) were studied to test for the effects of cleaning on their growth. These effects were examined by experimentally cleaning mussels and by changing mussel density. Treatment was performed twice, at two and four months after immerging the ropes. Two months after the first treatment and three months after the second treatment, mussels were harvested and measured (weight, length, width and thickness). Analysis of variance showed that none of the treatments resulted in increased growth of the mussels, nor did increased density result in decreased growth when compared with the control. It was concluded that it was not necessary to clean the shells to increase harvest.
