中文摘要:
      本文根据辽东湾中国对虾标志放流实验与重捕资料,对辽东湾中国对虾放流场的选择、种苗的放流规格和放流增殖效果进行了研究。根据上述实验分析表明,在辽河口海区进行对虾放流增殖是较理想的场所,在秋汛生产期洄游分布遍及辽东湾传统的中心渔场;放流种苗的适宜体长规格为5cm以上,回捕率较高,最高达3.31%。这将对辽东湾生产性对虾放流提供科学的依据。
英文摘要:
      Experiments of tagging and. recovery of Chinese Prawn (Penasus orienialis Kisninouye)were conducted in Liaodong Bay. Surveys were made under such topics as the choice of sites,the suitable sire of seeding fry and the result of recovery rate through tagging. During the past three years, thv total number of 123.572 tagged prawns were released and the total recovery number was 1, 233. The results showed that the mouth of Liao He River was an ideal site far releasing the tagged prawns. During the autumn harvest season, it was found that the migration and distribution of the the prawn covered the traditional central fishing zones. The tagged prawn was successfully recaptured in the spawning gorund and also in the overwintering ground. The suitable body length of the fry for tagging is over 5 cm.Tn this case, the rate of recapture is higher, its best percentage being 3.31%.This study provides a scientific basis for the eaplaitatian of production range of prawn releasing in Liaodang Bay.
