盐度对龟足胚胎及幼虫发育的影响

The Effects of Salinity on Embryonic and Larval Development of Pollicipes mitelle in Vitrof

叙述了盐度对体外培育的龟足胚胎及幼虫发育的影响 .水温 2 5± 1℃时 ,胚胎发育的适宜盐度范围为 1 5 .33～ 4 1 .78;最适盐度为 2 1 .38～ 2 8.5 5 .幼虫发育耐盐上限为 4 1 .78,下限为 2 1 .38;最适盐度为 2 8.5 5～ 35 .1

In this paper the effects of salinity on embryonic and larval development of Pollicipes mitella are reported. When water temperature is held at 25±1℃, the optimum salinity range for the development of embryonic is 15 33～41 78 .The best rate of hatching and fastest development of embryonic is 21 38～28 55.The upper limit and the lower limit of salinity for the development of larval are 41 78 and 21 38.The best survival and fastest development of larval is 28 55～35 16.
