|
Abstract: |
The eggs and larvae of longuefishes, Cynoglossus semilaevis and C. joyneri, were obtained from May to October 1979-1981 yrs. in the Bohai Bay. Their eggs all are pelagic, spherical in shape. The egg diameter of C. semilaevis is 1.00-1.24 mm oil globules 24-45 in number, and that of C. joyneri is 0.72-0.90 mm, oil globules 6-20. In larval stage, each has one or two elongate fin rays above the parietal. The myotomes are 10 + 46 = 56 and 9 + 42 = 51 respectively. |
