中文摘要:
      本文是从1963年4月25日至同年5月25日,在海南岛儋县洋浦湾用52GG筛绢制成的卫生鱼卵网拖取鱼卵标本16次,其中有5次是在晚7~9点;一次在中午,其余10次都是在上午7时30分~10时。 现将整理出的8种,内隶属鲱科 Clupeidae的 4种即脂眼鲱 Etrumenus micropus、玉鳞角Kowala coval、斑鰶Clupanodon punctatus、无齿鰶 Anodontoma chacunda;鱚科Sillagidae 的多鳞鱚 Sillago sihama;裸颊鲷科 Lethrinidae 的线棘裸颊鲷 Lethrinus nematacanthus;石鲈科 Pomadasyidae的三线矶鲈,paraprisipoma trilineatum;(鱼衔)科Callionymidae的一种Callionymus sp。 就该8种鱼卵、仔鱼拖到的时间及当时水温、盐度和孵化时间等归纳以下几个问题: (1)这些鱼类的卵及其仔鱼除三线矶鲈外,其他7种在本海区尚属第一次报道。 (2)该8种鱼卵均属圆球形,无色透明,彼此分离,天然受精卵浮于水面。在发育过程中有色素胞出现,脂眼鲱、玉鳞鱼、斑鰶、无齿鰶和三线矶鲈的卵黄有泡沫状龟裂,而(鱼衔)属的一种卵膜具有整齐的六角形龟裂纹(卵径0.61~0.68毫米),是其主要特征,与其他7种卵子极易区别。在16次采样中,它们分布在水温28~30℃、盐度30.70~31.62%之间。 (3)它们在湾内的产卵期均在4~5月前后,根据卵内的发育时间推测,其放卵时间均应。
英文摘要:
      The living specimens used for this study were towed horizontally by theHensen egg-net at Yangpow Bay, Hainan Island, from April 25th to May 25th,1963. The surface water temperature in the area where specimens were collec-ted varied from 28-30℃,and the salinity of the surface water from 30.70-31. 62‰. Altogether eight species of eggs and pre-larvae have been identified anddescribed briefly here. They are: 1) Etrumeus micropus, 2) Kowala coval, 3)Clupanodon punctatus, 4) Anodontostoma chacunda (Clupeidae), 5) Sillagosihama (Sillagimidae), 6) Lethrimus nematacanthus (Lethrimidae), 7)Paraprisipoma trilineatum (pomadasyidae) and Callionymus sp. (Callionymidae).Except Paraprisipoma trimineatum, the occurrence of the eggs and larvae ofthe other seven species are recorded for the first time in South China Sea alongthe coast of China. All the eggs of these eight species of fishes are bouyant and spherical.Except Callionymus sp.which bearing hexagonal reticulations on the egg membr-ane, the egg membranes of other seven species are smooth and thin, The-yolk granules of the eggs of paraprisipoma trilineatum and Callionymus sp. arehomogeneous,while those of the other 6 species are all with prominent segmen-tations.
