对黄海增殖日本对虾（ＰｅｎａｅｕｓｊａｐｏｎｉｃｕｓＢａｔｅ）群体的生长特性进行研究，并初步确定了该群体的合理开捕期。结果表明，（１）同大多数对虾种类一样，日本对虾也表现出雌雄生长的差异。雄虾生长较快，而雌虾能达到更大的个体。（２）在同体长条件下，该增殖虾体重比南海同种野生虾小。（３）体重生长据点在３个月左右。据此，我们认为在９月中旬开始捕捞较为合理。
The growth characteristics of the population of Penaeus japonicus Bate in the Yellow Sea were studied, and the reasonable harvesting period of the population was initially determined. The results showed that: (1) As with most shrimp species, Japanese shrimp also showed differences in male and female growth. Male shrimp grow faster, while females reach larger individuals. (2) Under the condition of the same body length, the body weight of the proliferating shrimp is smaller than that of the wild shrimp of the same species in the South China Sea. (3) weight growth positions in about 3 months. Based on this, we think it is more reasonable to start fishing in mid-September.
