本文探讨了厦门港莹虾类的种类组成及季节分布,并对其中的优势种亨生莹虾的数量、体长组成和性比率的季节变化进行研究,供今后开展莹虾的种群生态研究参考。一、材料与方法样品是1963年5月至1965年1月定期(每月农历初八、十五、二十三和三十日20∶00—20∶30)在厦门港的鹭江水道采集的。采集时船只固定在港中,依靠海水涨退的水流拖表层浮游生物。以粗、中、细三种网具(分别用30GG、60GG和XX10号的筛绢做成口径37mm的定性浮游生物网)各拖10min。标本用5%福马林海水固定保存。由于条
In this paper, the species composition and seasonal distribution of shrimp in Xiamen Harbor were studied, and the seasonal variation of the number, body length composition and sex ratio of the dominant species of Ying shrimp was studied for reference for future study on population ecology of Ying shrimp . I. Materials and Methods Samples were collected at the Lujiang River in Xiamen Port from May 1963 to January 1965 (monthly lunar eighth, 15th, 23rd and 30th lunar month 20:00 to 20:30) of. Collection of vessels fixed in the port, rely on seawater flow retreat surface plankton. In coarse, medium and fine three kinds of tools (respectively 30GG, 60GG and XX10 sieve made of qualitative 37mm diameter plankton net) drag 10min each. Specimens were fixed with 5% formalin seawater. Due to the bar
