✔ 最佳答案
The answer is reached by drawing a diagram:圖片參考：http://i238.photobucket.com/albums/ff245/chocolate328154/Econ015.jpg
When the import volume of seafood decreases, the supply drops from S to S1.
When people were afraid of eating poisonous seafood, the demand for it drops from D to D1.
When the decrease in demand is equal to the decrease in supply, the selling price remains at P but the Qd drops from Q to Q1.
As for more, the total revenue will drop as well becuase ( PQ1 < PQ ).

Sorry for a typing error, it should be because but not becuase.
