A STUDY OF INDIVIDUAL FECUNDITY OF THE HEMIBARBUS MACULATUS (BLEEKER) IN SOUTH LAKE WUCHANG

Gong Shiyuan; Liang Kaixue; Ku Yaomei, (Huazhong Agricultural University, Wuhan, 430070)  
Hemibarbus maculatus (Bleeker) is an economic freshwater fish widely distributedin China. A total of 149 specimens of H. maculatus (Bleeker) were collected from southlake wuchang on April 1 to 7, 1985 and characters of individual fecundity were invesig-ated. The results are summarized as follows: 1. The absolute fecundity (r) per individual varied from 4985 to 102850 (eggs)(average 43844) the relative fecundity (r/L) between 312 and 3280 (eggs/cm) (aver-age, 1728) and (r/W_n) between 66 and 203 (eggs/g) (average 136). 2. The relationship among the individual absolute fecundity(r), body length (L)and body-weight(W_n) can be expressed with the following equations: r=2399×10~(-5)L~(4·500) (S_b=0. 302, p0. 001), r=18IW-2257 (S_b=6. 195, p0. 001). 3 The individual fecundity (r, r/L) not only increases with increases of lengthand weight, but also changes with the maturation coefficient, egg diameter and age.
