| Abstract: | This paper reports comparison research on the morphological features and abundance distribution of eggs and larvae of Harengula zunasi Bleeker and
Clupanodon punctatus (Temminck & Schlegel) using mathematical methods such as t-test, linear regression with an independent variable, principal component analysis and hierarchical cluster analysis etc.. The specimens were taken from 1979 to 1982 in Bohai Bay by plankton nets by the Institute of Oceanology, Chinese Academy of Sciences. The main results were as follows: 1. Egg and yolk diameters between these two species in each stage were significantly different. Average egg and yolk diameters of Harengula zunasi were 1.47 - 1.56 mm and 0.81 - 0.92 mm , respectively; and that of Clupanodon punctatus were 1.28 - 1.36 mm and 0.96 - 1.01 mm respectively. 2. The larvae of these two species had quite similar shapes, and their change patterns were of apparently similar pattern when the yolks were absorbed. 3. There was significant correlation between any two among the five length features (body height, head length, standard length, preanal length and eye diameter) of each of these two species. They changed obviously from I to II stage of larvae, but the numbers of preanal and postanal myomers did not change. 4. The eggs and larvae of Harengula zunasi and Clupanodon punctatus occurred in the whole surveyed area. The spawning season of Harengula zunasi was from April to September, mainly from May to July, that of Clupanodon punctatus was from May to August, mainly from May to June. Offshoreward migratory tendency was apparent as Harengula zunasi developed from eggs to larvae. Shoreward migratory tendency was apparent as Clupanodon punctatus developed from eggs to larvae. |
