The autumn is small last year starfish appear
Red island is street Zhao Yongmei of ocean community vice secretary says on the west, the autumn had had a fisherman to discover the star entered more and more small lakes to breed an area last year, community passes this question to street report instantly at that time. After be brought up to prevent young sea star, overrun, breed a land that ever had used period of time basket net. After this still has starfish to gather in succession, and progenitive rate is very rapid.
