A Study on Cultivated Techniques of Chinese Giant Salamander in Basement with Gentle Flowing Water

Abstract:

In order to achieve the object of Chinese giant salamander (Andrias davidianus) large-scale cultivation in Shandong province area, an experiment on cultivation in basement with gentle flowing water was carried out. The experiment, set 2 age groups of 1 and 3 years old, analyzed many aspects of culture field construction, management of water quality, feed and disease prevention and treatment, and growth condition of Chinese giant salamander based on the result of biological measure. The results show that：After two years，the Chinese giant salamander′s growth rate of average weight reached 6874.5% and 167.5% and average length reached 254.3%和50.5% at 1 and 3 years old respectively; The growth rate of weight taken on a character of “slow-fast-slow”, and of body length reduced gradually with increased culture time; Specific growth rate appeared a rule of high before and low behind, significantly reduced in all follow with culture time; Growth inflexion was 3.38, indicated that 3～4 years old is the critical period of weight growth. In all, the Chinese giant salamander cultivated in basement with gentle flowing water，has advantages in growth rate of body weight and length faster, growth inflexion come forth earlier, cultivation cycle shorter, the study can provide reference for carrying out large-scale Chinese giant salamander culture in Shandong area.
