Title: Biological zero point of gonad development of Ruditapes philippinarum
Abstract: We have conducted an artificial promoting nature experiment on Ruditapes philippinarum from Dalian and Fujian province in artificial condition in 2004 and 2005; observed and recorded the average daily temperature and the laying of egg and sperm. Thereby,with the mathematical statistics methods and formula K= H (T-t) thermal sum beneficial,it is indicated that the biological zero point for the gonad development of Ruditapes philippinarum from Dalian is 6.774℃,and that from Fujian province is 10.990℃. The histological observation demonstrates that the average water temperature for half of Ruditapes philippinarum from Dalian and Fujian to enter into multiplication period is 7.0℃ and 10.1℃,respectively. Therefore,it is verified from the experiment that the biological zero points for the gonad development of Ruditapes philippinarum from the north and south sea areas are different.
