摘要
在温度２０±１℃和盐度２２─２４‰条件下，对海蜇螅状幼体和碟状幼体进行了窒息点和耗氧量的初步测定。结果表明：螅状幼体的窒息点低于０．１０ｍｇ·Ｌ，直径３．４─１０．２ｍｍ碟状幼体的窒息点为０．１７─０．２０ｍｇ·Ｌ。螅状幼体的个体耗氧量为２．９３μｇ·ｄ，耗氧率为２．６６ｍｇ·ｇ·ｈ（干重）：直径３．４、４．６和１０．２ｍｍ碟状幼体的个体耗氧量分别为４．７７、２５．４１和７９．４５μｇ·ｄ，耗氧率分别为４．９７、２．４６和１．１２ｍｇ·ｇ·ｈ（干重）。
The lethal DO concentration and oxygen consumption were determinated on scyphistoma and ephyra of Rhopilema esculenta under a temperature of 20±1℃, a saiinity of 22─24.Results showed that the lethal DO concentration for scyphistoma was less than 0.10mg·L , and those for ephyra, which the mean diameter was from 3.4mm to 10.2mm,was between 0.17 and 0.20mg ·L , The oxygen consumption and oxygen consumption rate for scyphistoma were 2.93μg· ind ·d and 2.66mg·g·h ,respectively. The oxygen consumption for ephyra, which the mean diameter was 3.4、.6 and 10.2mm,was 4.77、25.41 and 79.45μg·ind ·d ,and the rate of oxygen consumption for the corresponding ephyra was 4.97、2.46 and 1.12mg·g h ,respec-tively.
