口虾蛄耗氧量、耗氧率及窒息点初步研究

Preliminary Study on the Oxygen Consumption,Oxygen Consumption Rate and Suffocation Points of Aratosquilla oratoria

前言口虾蛄(Oratosquilla oratoria(DeHaan)系口足类甲壳动物,又名东方虾蛄、虾蛄,俗称琵琶虾。广布于中国、日本、韩国、东南亚地区。我国沿海均有分布,浙江沿海资源量颇大,为虾蛄类的优势种。随着海洋水产资源的衰退,早先不太被重视的口虾蛄也因其肉质鲜美、营养丰富而日益受消费者的青睐。

In this paper the oxygen consumption was determined by using the dissolved oxygen in experimental and contrast respiration chambers.The Winkler's way was used to determine the content of oxygen.Conclusions were drawn that the increase of oxygen consumption proportionally to the body length while the oxygen consumption rate inversely proportional to the body weight.Temperature,pH and sex had remarkable effect on the oxygen consumption rate of Orarosquilla oratoria,So did the light and starvation.But the effect of salinity on the oxygen consumption rate was not very remarkable.It was also concluded that the oxygen consumption rate changed obviously in 24 hours.The suffocation points ranged from 0.5734 to 0.6934 ml/l.
