就盐度对紫彩血蛤胚胎及幼虫发育的影响进行了研究。结果：紫彩血蛤胚胎发育的有效盐度范围为16．07～37．04，最适盐度范围为23．95～31．03。盐度为23．95，胚胎发育速度最快，孵化率最高，达98％；幼虫发育的适宜盐度范围为16．07～37．04，其中盐度为28．03，幼虫存活率和变态率最高，分别为78．8％和88．6％，盐度12．02～40．95对幼虫均无明显致畸影响 The effects of salinity on the development of embryos and larvae of Cladonia rubra were studied. Results: The effective salinities of the embryonic development of the clam were 16.07 ~ 37.04 and the optimum salinity range was 23.95 ~ 31.03. Salinity of 23.95, the fastest embryo development rate, the highest hatchability, up to 98%; suitable larval development salinity ranged from 16.07 to 37.04, of which salinity was 28.03, larvae survival and metamorphosis The highest rates were 78.8% and 88.6%, respectively. Salinity 12.02 ~ 40.95 showed no significant teratogenic effects on larvae
