【摘要】 <正> 溶氧的存在是对虾进行呼吸的前提,而呼吸又是对虾生命活动的基础。溶氧量高则促进其代谢、生长、发育及繁殖;低则成了限制因子。因此,对虾的耗氧量、耗氧率与窒息点的研究,不仅在对虾的生理和繁殖的研究上有着重要意义,而且在亲虾育苗与越冬过程中也具有理论和实践的价值。例如,我们可以借此计算亲虾运输、暂养、饲养、越冬等的放养密度,也可以为深入研究虾在氧不同分压下的呼吸、代谢以及窒息等情况,提供理论上的依据。尤其对当前如何强化培育越冬亲虾,如何充分和合理地利用海捕亲虾,提高产卵率,减少不必要的死亡,更有其现实的意义。但目前国内还没有这方面资料的报道,所以对此研究是十分必要的。更多还原

【Abstract】 The oxygen consumption, oxygen consumption rate and asphyxiation point of the spawner prawns have been determined. The results thus obtained are summarized as follows:The oxygen consumption of the spawner prawns individual-weighted from 39.0 to 111.2g, is 7.41 to 24.42ml/hr per tail at water temperature varying between 17.2℃ and 23.1℃. The oxygen consumption rate is 0.111 to 0.330 ml/hr per gram. And the asphyxiation point is 1.44 to 1.82 ml/1.The oxygen consumption and asphyxiation point of spawner prawns are generally higher than their respective values of adults. However the oxygen consumption rate of spawner prawns is generally lower than that of adults.更多还原
