Biological zero temperature and effective accumulated temperature of postembryonic development of Chinese mitten crab (Eriocheir sinensis)

Temperature is an important factor affecting the postembryonic development duration of Chinese mitten crab (Eriocheir sinensis). Biological zero temperature and effective accumulated temperature reflect the intrinsic relationship between temperature and developmental duration. In this experiment, th...

description Temperature is an important factor affecting the postembryonic development duration of Chinese mitten crab (Eriocheir sinensis). Biological zero temperature and effective accumulated temperature reflect the intrinsic relationship between temperature and developmental duration. In this experiment, the larvae of Jianghai 21, an improved species of E. sinensis bred in Sheyang area of Yancheng City, Jiangsu Province, were used as experimental objects. A single factor, three treatments and three repetitive constant temperature test (constant temperature was set at 20, 22 and 24 ℃, respectively) was designed to monitor the development temperature and duration of E. sinensis at regular intervals. The biological zero and effective accumulated temperatures were calculated and validated by the effective accumulated temperature formula. The experimental data and the local five-year historical monitoring data were analyzed by single factor variance analysis. The test results showed that: 1) There was no statistically significant difference between the experimental data of biological zero temperature, effective accumulated temperature and the historical data (P>0.05). It was confirmed that the biological zero and effective accumulated temperatures of E. sinensis were separately 6.91℃ and 274.18 ℃•d at the postembryonic stage. 2) Among the experimental temperature range, the larval development period of E. sinensis decreased with the increase of temperature. The above results can provide a scientific and theoretical basis for the study of postembryonic development of E. sinensis.
