广东省沿海对虾资源增殖工作起步较晚,但自1985年以来在沿岸10多个港湾、河口海区已人工放流对虾苗8亿多尾,其中2.5亿余尾标粗到体长3厘米以上放流(1989年前共放流5亿多尾,其中标粗到体长3厘米以上放流的7847万尾)。下面就广东沿海人工放流虾苗增殖对虾资源的效益进行初步探讨(因1990年虾汛期未结束,分析研究放流的数据用到1989年。见表1)。
Guangdong coastal shrimp resources proliferation started relatively late, but since 1985 more than 10 ports along the coast, estuarine waters have been artificial discharge of more than 800 million shrimp tail, of which more than 250 million tail length to 3 cm body length above the discharge A total of more than 500 million tales were released before 1989, of which 78.47 million were drafted to a body length of 3 cm or more. The following is a preliminary study on the benefits of artificially shrimp shrimp propagation in coastal areas of Guangdong Province (due to the fact that the shrimp flood season was not over in 1990, and the data of the study release were used in 1989. See Table 1).
