提出了一种基于手机拍照测量技术的黄鳝（ Monopterus albus）体长测定方法：只要用手机的手写笔作为尺寸参照物放在黄鳝旁边，即可通过拍照测定其体长；得到体长后可通过黄鳝体长-体重的回归模型进行体重估算。研究发现：体长-体重回归模型在估算较大的黄鳝时存在较大的误差，因此提出一种基于杠杆原理的利用手机手写笔作为秤杆来准确测量黄鳝体重的方法，最后将上述方法及模型集成到安卓手机软件中，构建了一个基于安卓手机的黄鳝体长、体重及肥满度的测定系统。结果表明：该系统测定体长、体重及肥满度的相对误差分别为1％、4．9％及5％；该系统可准确、方便、无损地测量黄鳝体长、体重及肥满度等参数。

In order to ensure the survival of the fish , the pH, dissolved oxygen, temperature and other parameters should be controlled in a suitable range in the process of long-distance transportation of high density .This article describes an automatic monitoring system ,using pH meters dissolved oxygen analyzer and temperature sensor to detect related parameters respectively .During the transportation process, the fish excrement was cleared by a filter system , which helped to control the pH .The Dissolved oxygen in water was controlled by an oxygen pump and a composite oxygen-increasing agent.Also, the water temperature was controlled through the chiller water system .through tests, the operational rules of container transportation of live fish were determined as follow:appraisal, temporary culture, pre-cool, encasement, transport, re-warming.The results showed that after appraisal and temporary culture , the survival rate of fish can reach as high as 95%after 72 hour's transportation under the condition of a 1∶2 mass rate of water to fish, pH 6.5-8, the temperature controlled at 7 ℃ and the temperature change rate is less than 2 ℃/h, dissolved oxygen content of 8-13 mg/L.
