该研究通过对虾标志放流进一步证实了中国对虾在东吾洋内外行动分布的规律，确定了两种放流规格种苗的回捕率。在贝类示范区，采取将牡蛎从中、高潮区移至低潮区，使单产从0．09吨／亩提高至0.18吨／亩，有效地提高了产量。查明了在混合养殖区内牡蛎性腺发育饱满度的季节变化与 The study further confirmed the law of the distribution of shrimp in shrimp in and outside of the East China Sea through shrimp discharge, and determined the recovery rates of seedlings in two kinds of release standards. In the shellfish demonstration area, the oyster was moved from the mid-climax area to the low-tide area and the yield was increased from 0.09 tons / mu to 0.18 tons / mu, effectively raising the output. The seasonal variation of gonadal development in oysters in the mixed culture area was identified
