本文研究福建东山岛西埔湾港养1099尾斑(鱼祭)的鳞片年轮、渔获年龄结构和体长频率分布,并结合周年逐月的生物学资料,对其体长与鳞长、体长与体重、肥满度、相对增长率和生长指标以及个体绝对生殖力和相对生殖力作了分析。生长参数拟合的生长方程能够反映其生长规律。依据生活史生态学参数,斑(鱼祭)应归属于r选择型。文中还讨论了西埔湾港养斑(鱼祭)资源的合理利用和增养殖措施。 In this paper, we studied the annual ring length, catch age structure and body length frequency of the 1099 tail spot (fish sacrifice) in Xipuwan Port, Dongshan Island, Fujian Province. Combined with the biological data of each month, Body length and body weight, fatness, relative growth rate and growth index as well as individual absolute fecundity and relative fecundity were analyzed. The growth equation fitted by growth parameters can reflect its growth pattern. According to the ecological parameters of life history, spot (fish sacrifice) should be attributed to the r selection type. The paper also discusses the rational use and cultivation measures of Pica (fish sacrificial offering) resources in Xipu Bay.
