Said on 27 June 2008 and July 4, Qingdao Ocean and Fishery Bureau of Laoshan Bay the Japanese shrimp proliferation releasing, releasing a total of 63,282,000 Japanese shrimp fry, and the average body length of 8.1-11.0mm. In this thesis, the follow-up survey of the bottom trawl tune visit statistics method of combining research restocked the Japanese shrimp distribution, growth regulation, and recapture rate on the proliferation of the effect of releasing the assessment, aims for the future Japanese shrimp proliferation discharge and management to provide a scientific basis. The results show that: In August 2008, the Japanese shrimp releasing mainly distributed in the the Aoshan head nearshore and shallow waters of tubules Island (water depth less than 5m) With the water temperature drop in January, the Japanese shrimp gradually migrate to deep water. The releasing shrimp groups in Japan March 8-10 2008 recapture only 0.48%. This article by the recapture shrimp samples weight, body length data analysis, research its body length and weight, and calculated restocked Japanese shrimp growth equation and growth rate equation is as follows: females: males: Based on the above the growth equation calculation draw female Japanese shrimp growth inflection point t r = 87.7d weight maximum daily increase dw tr / d tr = 0.39g; The male Japanese shrimp growth inflection point t r = 78.2d the weight maximum daily increase dw tr / d tr = 0.35g. It can calculate the Laoshan Bay the Japanese prawn female releasing males about September 2, 2008 and August 24, respectively, to achieve the maximum growth rate, and accordingly catchable should be controlled in mid-September appropriate. In 2008, Qingdao Ocean and Fishery Bureau in Guzhen mouth Wan first flounder fingerlings proliferation releasing flounder releasing on September 25, 2008, to choose the length specifications 9cm more robust seed about 10,000 listed logo flag discharge stream. The papers of flounder in Guzhen mouth Bay proliferation releasing the preliminary study, aimed at Guzhen mouth Bay flounder enhancement effect assessment to provide basic information. The results show that: capture flounder on March 11, 2009 17, average body length of 23cm, average weight 202g; April 11 capture flounder 19, average body length 26cm, average weight 262g; indicating that the growth of releasing tooth flounder in good condition, taking into account the growth cycle of the flounder, the enhancement effect for further investigation and assessment have to wait until the fall of 2009.
