The bighest value of gonad index, value R and biggest primary branch diameterof gonad are found from July to middle of Angust. The spawning indivaduals in thisperiod account for 85--100% of total spawning indiveduals in a year. 2. As to histology, the development of gonad can be divided into 5 stages: rest,Proliferation, growth, maturation and spawhing periods. The period of tho spawningpeak varies with tbe size of the indivdual and locality. The bigger individual inshallow water shows a tendancy to spawn earlier. 3.
