材料与方法2005年和2006年（5月和6月）在产卵场采用电捕法捕获产卵时的七鳃鳗，将不同形态的产卵个体同时纳入分析。图1显示了捕获点的位置。表 1 显示了根据一组具有分类学意义的形态特征识别出的每只七鳃鳗的种类 [3]，以及捕获地点和时间的地理位置和年份。除了 20 只产卵鱼和 1 只小鲑鱼（一种已变形并正在迁徙到海中的羔羊猎物）
MATERIALS AND METHODS Lampreys were caught during spawning in the years 2005 and 2006 (May and June) in the spawning grounds by means of electric fishing in such a way that spawning individuals of different forms were simulta neously included into analysis. Figure 1 shows the location of the catching sites. Table 1 shows the species of each individual lamprey identified on the basis of a set of morphological characters that have taxonomic significance [3], as well as the geographic site and year where and when it was caught. In addition to 20 spawners and one smolt (a lam prey that had transformed and was migrating to the sea
