内容記述 | Adult specimens of the cardinal fish, Apogon niger Doderlein used in this study were collected from Tomie Bay (32° 37' N, 128ー 46' E), Goto Island, Nagasaki Prefecture, during the months of July to November 1973 (Figs. 1, 2). Fish behaviors especially mouth breeding habits, form of eggs as well as the newly hatched larvae were closely investigated. In the cardinal fish, Apogon niger, females fish usually grew larger in size than males (Fig.3). The spawning period of this fish seemed to last considerably long from July to October. It was the male fish that took care of the incubation of eggs by keeping them in its mouth (Figs. 1, 5). During this time its isthmus was distended. From the fact that the stomach of the male fish contained no food particles but some undigested eggs which might have been swallowed at the time of catch, it was thought that the digestive tract of the male fish dose not function during the period of incubation (Table 1). The eggs being incubated were almost spherical in shape and creamy in colour measuring from 0.6 mm. to 0.7 mm. in diameter. Filamentous adhesive elements could be obviously seen joining eggs together into a big oval mass (Figs. 4, 5). Each egg mass was comprised of 15,000 and 18,000 eggs in 2 cases. The temperature in the incubating tank was maintainted at 22℃ to 25℃. The newly hatched larvae being 2.3 mm. to 2.7 mm. in total length possed a fairly large egg yolk with mouth and anus already opened (Fig. 8). | |||||
